I NTENDED PRODUCT USAGE
This fireplace is intended for supplemental heating only and is not intended for use as a primary heating
system.
This fireplace is designed to sit directly on a combustible floor. The fireplace must be installed with clearances
to combustible building materials as specified by this manual. Only parts manufactured by Monessen Hearth
Systems and labeled for use with this fireplace should be used in the installation of the fireplace except for
special roof flashings that may be fabricated locally. The use of improper parts in the installation can be
hazardous and voids the warranty offered by Monessen Hearth Systems.
This fireplace is designed to burn solid wood fuel (wood), UL- classified processed solid fuel fire logs, or a
certified decorative gas appliance may be installed in the fireplace as described later by this instruction manual.
This fireplace is not designed to burn coal, unplumbed liquid fuels, unplumbed gaseous fuels or household
refuse. Any attempt to burn these fuels in the fireplace can be hazardous.
NOTICE:
THIS FIREPLACE IS NOT DESIGNED FOR INSTALLATION IN MANUFACTURED HOMES WITHOUT A VENTED ATTIC SPACE. THE
FIREPLACE MAY BE INSTALLED IN MANUFACTURED HOMES WHICH HAVE A VENTED ATTIC SPACE IF THE FIREPLACE IS EQUIPPED WITH
GD36B OR GD36PB GLASS DOORS, AN AK6 OUTSIDE COMBUSTION AIR KIT (INSTEAD OF THE AK4 OUTSIDE COMBUSTION AIR
SVTR FIRESTOP THIMBLE,
AND THE MINIMUM INSTALLED HEIGHT FROM FLOOR TO FLUE OUTLET IS 14 FEET. SEE FIGURE 1.
KIT OFFERED FOR RESIDENTIAL TYPE HOMES AS DESCRIBED LATER BY THIS INSTRUCTION MANUAL), A
CAUTION: DO NOT USE A FIREPLACE INSERT OR OTHER PRODUCT NOT SPECIFIED FOR USE WITH THIS FIREPLACE.
WARNING: IMPROPER INSTALLATION OR USE OF THIS FIREPLACE WILL VOID ITS WARRANTY AND CAN CAUSE:
1. Damage to the fireplace from overheating.

OPERATION GUIDELINES
5
As wood is burned in the fireplace, room air entering the fireplace is circulated around the fireplace firebox. This air
circulation protects the firebox from overheating. Air circulation through the fireplace must not be blocked or restricted
in any manner. Blocking or restricting air circulation through the fireplace can cause a fire hazard.
In residential type installation, an AK4 outside combustion air kit may be connected to the left side of the fireplace to
allow outside air to enter the firebox through a dampered opening in that side of the fireplace. This “outside combustion
air” feature reduces the room air used for combustion and prevents excessive heat loss from the room. When the
fireplace is in use, the fireplace’s “outside combustion air” damper connected to an AK4 may be opened to allow air
from outside to enter the fireplace firebox. When the fireplace is not in use, the “outside combustion air” damper
should be closed to prevent cold air from entering the firebox. An “outside combustion air” damper is open when its
control lever is up, and closed when its control lever is down. A control lever for the “outside combustion air” damper
is located inside the firebox near the top of the side firebrick on the left side of the fireplace. The design of the
fireplace allows the routing of the combustion air duct downward or horizontally to obtain the outside combustion air;
this permits flexibility in planning your installation. See Figures 24 thru 27 and their instructions for typical installation
of outside combustion air kits. Review the precautions and recommendations in this manual pertaining to outside
combustion air. Outside air for combustion is optional in residential type installations unless required by
local codes; it is mandatory in manufactured home installations. Use an AK6 outside combustion air kit in
manufactured home installations, instead of the AK4 offered for residential type installations.
Glass doors (model GD36B or GD36PB by Monessen Hearth Systems) may be installed to receive the maximum
benefit from your fireplace. For large fires, the maximum heating benefit from the fireplace will be obtained with the
doors open due to the high amount of radiant heat being emitted out of the front opening of the fireplace. With a
small fire, or before retiring in the evenings, it is best to operate the fireplace with the doors closed to prevent
excessive room air from being drawn up the chimney. When the doors are open, the mesh screens should be closed
to help keep burning embers from popping out of the firebox.
Glass doors are mandatory on fireplaces installed in manufactured homes.
WARNING: Fireplaces equipped with glass doors should be operated only with the glass doors fully open or fully
closed. If doors are left partly open, gas and flame may be drawn out of the fireplace opening, creating risks of both
fire and smoke.
The fireplace also is equipped with a flue damper, which must be open when the fireplace is in use. The flue damper
control lever is located inside the fireplace. The counterweighted damper is operated by simply pushing up to open
or pulling down to close the damper. When the fireplace is not in use, the damper should be closed to prevent cold
air form entering the chimney as well as preventing warm air in the room from escaping up the chimney. NOTE: It
is normal for a small amount of smoke to be released from the upper portion of the fireplace the first few times you
use your new Monessen Hearth Systems fireplace. This results from an oil residue on the metal. Open a door or
window to allow the smoke to escape.
The grate included with this fireplace helps to appropriately locate and contain the burning wood. Failure to use this
grate may cause overheating of parts of the fireplace and allow large pieces of burning wood to roll forward out of the
firebox. If the grate becomes warped or damaged, it must only be replaced by a Monessen Hearth Systems 055119
grate.
All fireplace chimneys are in direct contact with cold air on the exterior of the structure. Consequently, when the
fireplace is not in use, cold air can fall down the chimney of the fireplace to cool off the fireplace chase. Therefore,
the fireplace chase must be insulated to minimize the risk of cold air infiltration to the home. Even if the fireplace
chase is adequately insulated, this cannot completely ensure that cold air infiltration into the structure will be eliminated.
Cold air infiltration is a possibility with any fireplace or device that freely communicates with the air on the outside of
the structure. Today’s homes are more energy-efficient and, therefore, better insulated and tightly constructed.
Unfortunately, when air is removed from the house, as by a bathroom fan, or consumed by a furnace, additional air
is needed to replace the air consumed. Unless the additional air is
4
53D9031. Rev 1 03/03
6
OPERATION GUIDELINES
supplied, this can cause a negative pressure in the home. When this happens, the house will draw in outside
air from the cracks in the windows, down the fireplace flue or other locations of air leakage in the home.
Because cold air infiltration may be unavoidable in some structures, Monessen Hearth Systems is not responsible
for heat loss or air infiltration through or around the fireplace.

FIREPLACE LOCATION
CAUTION: Do not install fireplace over carpeting.
This fireplace does not weigh more than large pieces of furniture and can normally be located near a load
bearing wall without requiring additional foundations or supports. If however, the fireplace is to be trimmed
with a heavy stone or brick facing and hearth extension, be sure the supporting structure is adequate.
Figures 4 and 5 provide dimensional details of the fireplace, required spacing to combustible walls, and some
suggested fireplace locations. When selecting a location, choose one that is away from frequently opened
doors, central heat outlets or returns, or other places where air movements may disturb the airflow around the
fireplace. Air turbulence near the fireplace may cause smoke to spill out of the fireplace opening.

INSTALLATION PREPARATION
Survey the planned location for the fireplace for overhead plumbing or electrical wires, etc., that might complicate
the installation or endanger persons installing or cleaning the chimney. Avoid a location where the chimney
cap will be near abrupt changes in the roof shape, nearby wall or embankments, under or near trees or above
the roof of a single story wing of a two story building as shown by Figure 8. All these conditions can cause
turbulence or pressure conditions that can cause poor chimney draft and smoke spillage from the fireplace
opening. Elbows may be used to offset the chimney to avoid obstructions or to locate the chimney cap in a
preferred location. Refer to the sections of this manual pertaining to chimney offsets for instructions on proper
elbow use. Poor installation or location of the chimney cap and/or components can cause wind blown rain to
enter the chimney.
Be sure the selected location will allow a 14˚" square combustible material-free space for the chimney to pass
through. If the chimney is to pass through living or storage spaces, be sure there is adequate space to enclose
the chimney to avoid personal contact with, or damage to, the chimney. If the fireplace is to be installed on an
outside wall, the surrounding walls (chase) should be constructed and insulated as shown by Figure 6. Failure
to insulate the fireplace from outside temperatures will cause heat loss through and around the fireplace.

The ability of insulating material to retard the transfer of heat may be expressed as either Thermal Conductance (C), Thermal Conductivity (K), or Thermal Resistance (R). The mathematical relationship of these
values and the formulas for converting one value to another is as follows:
FIGURE 11
C=K divided by the material thickness
(Example C = .43 divided by 1/2 (.50)
C = .86)
K = C multiplies by the material thickness
(Example K = .86 multiplied by 1/2 (.50)
K = .43)

SAFETY STRIP
With either type hearth extension minor shifting of the supporting floor or expansion and contraction may
eventually cause a crack to develop between the hearth extension and the face of the fireplace. To help
prevent the crack from developing, the hearth extension materials must be firmly fastened in place. Wall ties
should be screwed to the face of the fireplace and imbedded in the mortar joints of brick, stone, or other noncombustible materials. The metal safety strip packed with the fireplace must be placed beneath the fireplace
and extended under the hearth extension or into a mortar joint of the hearth extension as shown by Figures 10,
11, and 12. In the event a crack does eventually develop, the metal safety strip will serve as a barrier to
prevent sparks or embers from falling from the fireplace onto combustible flooring materials.
The hearth extension must not block the side air vents, or air inlet louvers on the lower front of the fireplace.
These openings must be unobstructed to assure an adequate flow of cooling air around the firebox. If the
fireplace is equipped with a blower, or may be equipped with one at a later date, the hearth extension must not
prevent the removal of the lower louver panel for servicing the blower. Plan adequately by determining the
finished height of the hearth extension to be used and elevate the fireplace on a platform, if necessary, to
prevent obstructing the air openings or lower louvered panel.

1. Refer to Figure 1 for an example of a typical installation of the fireplace components.
2. Be sure the location of the fireplace will provide the required clearances indicated by Figures 1, 2, 4, & 5
and the minimum chimney air space clearance to combustibles of two inches.
3. Set the fireplace in the desired location and be sure it is securely supported and leveled. Check the face
of the fireplace with a carpenter’s level and if it is not plumb; correct it by placing shims under the edges of
the fireplace.
4. Block in the fireplace to prevent any shifting of the firebox. Secure the fireplace with nails or screws
through the flanges located on each side of the fireplace. Do not enclose the fireplace until the combustion
air duct and chimney pipes are installed.
NOTE: Some local codes may require electrically grounding the fireplace and chimney.
CHIMNEY INSTALLATION
In order to assure safe and satisfactory performance of the fireplace, it is very important to properly install the
chimney. This is an important part of the installation and the sections of this manual pertaining to chimney
installation should be reviewed very thoroughly.
For your safety, some of the important things to remember in regard to chimneys are listed below:
1. Use only parts and accessories labeled for use with this fireplace.
2. Use only undamaged parts and accessories.
3. Enclose the chimney where it passes through the living spaces to prevent contact with and possible damage to the chimney.
4. Install firestop spacers at each ceiling level.
5. Install the proper chimney cap or chimney housing on the chimney to prevent the entry of rain and debris
into the chimney and to assure the proper venting of smoke.
6. Do not use more than four elbows in the chimney.
NOTE: To select the proper chimney height, refer to Figures 1, 7, 9, and 14. The flue outlet must be a
minimum of three feet above the highest point where the chimney penetrates the roof and a minimum of two
feet above all portions of the building within ten feet. If the chimney is to include elbows to offset the chimney,
refer to the Chimney Offset and Cap Installation section of this manual. There must be at least two inches air
space between all sections of the chimney and combustible materials between floors.

1. Lay out, cut and frame openings through all ceilings and the roof at the point where the chimney will pass
through. Unless the chimney is to be offset, the point where the center line of the chimney will pass
through the ceiling and roof can be determined with a plumb line as shown by Figure 15. The fireplace
should be located in the planned installation position. After the center line is established and a nail is
driven to mark the point, the opening can be cut if you are satisfied with the chimney location relative to
ceiling and roof joists and/or any other obstructions. The roof opening center line should be marked by
driving a nail through the roof from underneath that will penetrate the roof and can be located from the
rooftop. If the chimney is to penetrate a pitched roof, the hole in the roof must be rectangular instead of
square and should be sized according to Table1.
2. Install the firestop spacer as required from beneath the ceiling unless the space above is attic space. In an
attic, the firestop spacer should be installed at the floor level of the attic. Figure 17. You must have joists
or headers on all four sides of the spacer and use a minimum of four 8-penny nails to secure the spacer.
3. To install the “S” series chimney sections, insert the male end of the flue, the smallest diameter pipe, into
the flue outlet of the fireplace and press down until the snap locks engage. Continue the process, adding
the chimney sections on top of each other until the chimney is at least six inches above the roof opening on
all sides. As the chimney sections are installed, check each joint to make sure it is properly locked to the
previous section. If additional strength of the outer pipe joints is desired, you may use two or three sheet
metal screws placed through the area where the outer pipes overlap one another. To install these screws,
drill a 1/8-inch diameter hole through the chimney sections, taking care not to penetrate the inner flue pipe.
Warning: Be very careful when drilling the holes into the outer pipe. The drill must not penetrate the inner
stainless steel pipe.
NOTE: If you intend to have a total fireplace installation of more that 30 feet you must use chimney support
model SCS at or below 30 feet to support the weight of additional chimney pipe.
To install the chimney support, place the crimped end of the flue and outlet air duct portions into the last section
of chimney pipe. Push down until the outside or inlet air duct of the chimney support overlaps and snap locks
the chimney support into the chimney section.
Nail the support straps tightly to a building frame member or ceiling joist as shown by Figure 16. You must use
at least two 8-penny nails per strap.

ELBOW INSTALLATION
The following are important points that should be observed when installing elbows on the fireplace:
1. The support straps of all elbows not installed directly on top of the fireplace should be nailed securely to the
surrounding structure. This allows the support strap to carry the weight of the chimney above the elbow
and prevents this weight from breaking the elbow or chimney sections apart. Figure 18.
2. Elbows should not be used in any combination that inclines the chimney more than 30 degrees from
vertical.
ALL FOUR SUPPORT
STRAPS MUST BE NAILED
TO FRAMING MEMBER
AROUND THE ELBOW WITH
A MINIMUM OF TWO (2)
8-PENNY NAILS PER STRAP.

3. The limitations on the quantity of elbows per chimney are as follows: If the total height of the fireplace and
chimney is — 13' 6" or more — two elbows may be used in the chimney. 21' 0" or more — four elbows
may be used in the chimney.
4. The inclined portions of chimneys that pass through living spaces likely to be used for storage should be
enclosed to avoid contact with and possible damage to the chimney. The minimum air space of two inches
between the chimney and enclosing materials must be maintained. Figures 20 and 21 illustrates elbow
installations.
5. The length of the inclined portion of chimney between elbows must not exceed 6 feet when unsupported or
20 feet if the chimney is supported at six-foot intervals with support such as metal support straps.
6. When enclosing the elbows and inclined portions of the chimney, enclosing materials must be installed
vertically to maintain the required two-inch minimum air space clearance to the chimney at the extremities
of the offset. It is recommended that enclosing material not follow the inclined portions of the chimney.
OFFSET INSTALLATION SEQUENCE
1. Determine the location and amount of offset required, then select the combinations of chimney sections
and elbows required from the offset chart. Refer to Table 2.
2. Install the first SE30 elbow by placing the extended flue into the mating part of the fireplace or chimney
section. Push down until the outside or inlet air duct of the elbow overlaps and the snaps lock the elbow
into the fireplace or chimney section.
3. Nail the support straps to the framing member with a minimum of two 8-penny nails per strap.
4. Install the sections of pipe between elbows until the proper number of chimney sections have been installed.
5. Install the second elbow to return the run of the chimney to vertical.
6. Nail the support straps of the second elbow to a building frame member.
7. Continue installing the vertical portion of the chimney.
NOTE: If the inclined portion of the chimney passes through a floor or ceiling, an SF30 firestop spacer should
be installed to provide the firestop and support required. Be sure proper spacing in maintained between the
chimney and combustibles. Figure 19.

SPECIAL NOTE: The proper height as previously explained is important to assure proper draft and safety. The
chimney cap extends the flue outlet four inches above the top of the last section of chimney. This should be
kept in mind when determining the proper height for the chimney. The chimney should not be extended more
than 90 inches above the supporting roof structure without additional support. In the case of an “A” frame type
construction or other steep pitch roofs that require more than 90 inches of chimney above the roof, a support
should be attached to the chimney at the 90 inch level that is strong enough to support a wind load of 3-1/8
pounds for each inch the chimney extends above 90 inches. The flue outlet must be a minimum of three feet
above the point where in penetrates the roof. Figure 14.
CAUTION: Be careful to avoid electrical shock hazard when contacting wires to the metal chimney components.
1. Extend the regular chimney sections until the top of the chimney is 4 inches below the total flue height
desired. Do not snap the last section of inlet air duct or largest diameter pipe in place until Step 3 is
completed.
2. Remove the shingles from around the chimney so that the flashing may be installed, with the upper part of
the flashing under the shingles.
3. Set the flashing on the roof and scribe a line around the flashing, then cut the top off the flashing by cutting
1/4 inch below the scribed line. This should increase the diameter of the flashing outlet sufficiently to allow
the flashing to be placed over the chimney. See Figure 22.
4. Snap the last section of inlet air duct in place and slide the flashing over the chimney. Adjust the chimney
to assure that the proper minimum clearances are maintained.
5. Nail the flashing securely in place with eight nails.
6. Seal the crack between the top of the flashing and the chimney with mastic. Leave some excess mastic at
this area to be used in step eight. NOTE: Use pliers and wear gloves when performing step seven to
minimize the danger of cutting your hands on the edge of the storm collar.
7. Place the storm collar around the chimney and put the collar together like a belt in belt loops. Slide the end
of collar under the two loops on the other end with the loops facing up. Overlap the ends of the collar until
it is tight against the chimney. Bend the free end of the collar back over the loops to hold the storm collar
securely together. The excess end of the storm collar may be trimmed off.
8. Slide the storm collar down snugly against the flashing until the excess mastic left in step six is forced up
into the crack between the storm collar and the chimney. This should make the joint between the flashing
and the chimney watertight.
9. Install the chimney cap by placing the cap into matching parts of the last chimney section. Push down until
the brackets on the bottom of the chimney cap sits on the chimney pipe. Then punch or drill 1/8 inch
diameter holes in the inlet air duct (chimney pipe) where specified on the brackets and fasten it down with
the No. 8 screws provided. Do not penetrate the inner stainless steel pipe while installing the screws.
10. Check all the parts of the fireplace, chimney and chimney termination cap to assure that no parts have
been damaged or bent during installation and that all parts have been installed properly.
NOTE: The metal used for the chimney cap has a rust protective coating but the cut edges of the parts are not
protected. To prevent rusting and rust staining of nearby structures, exposed parts of the chimney and chimney
cap should be detergent washed and painted with a galvanized primer paint.

NOTE FOR STRAIGHT RUN CHIMNEYS:
Chimney support required at 25' chimney height.
NOTES FOR CHIMNEYS WITH ELBOW OFFSETS:
The length of the inclined portion of the chimney between
elbows must not exceed 6 feet when unsupported, or 20
feet if the chimney is supported at 6 foot intervals using
either metal support straps or an LCS chimney support.
The LCS chimney support when installed at a 30 degree
angle will add 8" of rise and 4-5/8" of offset to the chimney
height calculations.
CHIMNEY CAP CHASE INSTALLATION
The preinstalled chimney sections should be no more than 10 inches below the top of the chase. The installation
should be planned so that either a two-foot or three-foot chimney section will be used for the top section. This
is necessary to ensure complete engagement of the inlet air telescope and chimney cap into the top section.
CAUTION: Be careful around electrical wires to avoid the electrical shock hazard of contacting the wires with the
metal chimney components.
NOTE: When two fireplace chimneys are terminated above the same chase, the centers of the chimney caps
should be at least 24 inches apart to help prevent smoke from a fireplace in use from being drawn down the
chimney of a fireplace that is not in use. Additional spacing between caps or staggering the height of the caps
will further lessen the likelihood of this occurring.
1. Extend the chimney sections until the top of the chimney is not more than 10 inches below the top of the
chase.
2. Center the hole in the chase cover over the chimney. The chase cover overhang should be lanced, formed
over the chase and secured with nails. This prevents water from seeping under the chase cover. If two or
more chase covers are to be used on the same chase, they should be soldered together to form two
watertight seams.
3. Place the inlet air telescope inside the hole in the chase cover and lower it down into the mating pipe of the
chimney until the flange on the telescope section rest on the flange of the chase cover. Note: All telescoping
sections should extend a minimum of three inches inside the mating chimney pipes.
4. Install the SCL or SQL8 chimney cap by placing the cap into the matching duct telescope and flue telescope
of the last chimney section as shown by Figure 23. Lower the cap until the brackets on the bottom of the
chimney cap rests on the raised flange of the flat flashing, punch or drill 1/8 inch diameter holes in the
raised flange of the flat flashing, and fasten the cap to the flashing with the No. 8 screws provided.
5. Check all parts of the chimney and chimney cap to assure that no parts have been damaged or bent during
installation and that all parts have been installed properly.
NOTE: The metal used for the chimney and chimney cap has a rust-protective coating but the cut edges of the
parts are not protected. To prevent rusting and rust staining of nearby structures, exposed parts of the chimney
and chimney cap should be detergent-washed and painted with galvanized primer paint.

1. Push the insulation back approximatly 2"
from the end of each duct .
2. Slip each duct over the duct connector until
an equal length of the connector extends into
each duct.
3. Place a duct clamp over the end of each duct
and tighten it down snuggly.
4. Push the insulation back into place and over
the duct clamp.
OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS
OUTSIDE COMBUSTION AIR RECOMMENDATIONS (CONTINUED)
1. Extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air
assembly should be avoided. These conditions will increase the resistance to the free flow of air through
the duct. Refer to Figures 1 and 27 for methods of installing the outside air for combustion assemblies.
2. The combustion air assembly should be located at an exterior location, which is not likely to be accidentally
blocked in any manner. The assembly should be located above the snow line to prevent blockage by snow
accumulation.
3. The combustion air inlet assembly should never be mounted in a garage or storage area where combustible
fumes such as gasoline might be drawn into the fireplace.
4. Combustion air can be drawn from the crawl space under a house when an adequate supply of air is
provided by open ventilation.
5. Do not take combustion air from attic space or garage space.

COMBUSTION AIR ASSEMBLY
MODEL AK-4 COMBUSTION AIR ASSEMBLY
1. Remove the cover plate from the 4-inch outlet opening location on the left or right outside of the fireplace.
DO NOT remove the cover if the outside air will not be connected.
2. Place the insulation ring between the AK-4 starting collar and fireplace wall and place the starting collar (4
inch) into the hole on the side of the fireplace. Fasten it in place with the four sheet metal screws provided.
Figure 24.
3. Cut a 6-inch diameter opening for model AK-4 in the outside wall covering where the outside vent is to be
located. Figure 25.
4. Select and cut a piece of duct sufficient length to attach to the fireplace and protrude at least three inches
beyond the face of the wall to which the AK-4 inlet air vent will be attached. The duct may be cut with a
standard pocket knife (use FP-4 U duct for maximum efficiency and safety). Do not use a combustible
duct. Always use UL Listed Class 0 or 1 duct material.
5. If the duct is the insulated type, push the insulation back from one end of the duct approximately two
inches. Figure 26.
6. Slip the exposed end of the duct over the starting collar on the fireplace.
7. Using the sheet metal screws provided, secure the duct end to the collar attached to the fireplace.
8. Nail or screw the combustion air assembly to the surface of the wall.
NOTE: If the wall covering is brick or stone, use appropriate masonry fasteners. Mount the combustion air
assembly with “TOP’” upward to prevent cold air from entering through the wall. If it is necessary to splice the
duct, a model 403-duct connector should be used to splice duct sections.
GAS APPLIANCE INSTALLATION
WARNING: Improper installation or operation of a gas appliance in this fireplace can allow unburned gas to leak
out which will cause a fire or explosion hazard, or the release of poisonous carbon monoxide into the dwelling
which can cause serious injury or death to its inhabitants. To reduce these risks to a minimum, the following
important notices and instructions should be read and followed carefully.
IMPORTANT NOTICES:
1. The provision for a gas line is intended for connection to a decorative gas appliance which has an automatic
shutoff device and complies with the Standard for Decorative Gas Appliances for Installation in Vented
Fireplaces, ANSIZ21.60. If a decorative gas appliance is installed, it must be installed in accordance with
the National Fuel Gas Code, ANSIZ223.1.
CAUTION: “When a decorative gas appliance is installed, the fireplace damper must be set in the fully open
position at all times."
24
53D9031. Rev 1 03/03
GAS APPLIANCE INSTALLATION
CAUTION: If an unvented gas appliance is installed in the fireplace, the gas appliance must only be operated
with the fireplace glass door fully open (if included). Only unvented gas log set which have been found to
comply with the standard for unvented room heaters, ANSI/IAS/AGA Z21.11.2, are to be installed in this
fireplace.
WARNING: Do not operate an unvented gas log set in this fireplace with the chimney removed.
The installer of the fireplace and gas appliance must describe the operation of the fireplace and appliance
to the people who will be operating them and leave all instruction manuals with the operator of the appliance.
2. An approved gas shut off valve must be located outside the fireplace in an area accessible to the users of
the fireplace.
3. All gas piping and fitting must be either steel or malleable iron. Unions must be of the ground joint type.
4. Some code authorities prohibit or place restrictions on the use of gas appliances in fireplaces. Check with
local code authorities before proceeding with the installation.
5. The gas appliance and all connecting gas piping should only be installed by a licensed gas appliance
installer. See Figure 28 for the gas line opening dimensions on the fireplace.
6. The installer should advise the persons who will use the appliance to set the fireplace damper in the full
open position when the appliance is in use.
7. See Figures 29 and 30 for acceptable combustible mantel locations if an unvented gas appliance is being
installed in the fireplace. See Figure 31 for acceptable combustible mantel location if the fireplace is being
installed to burn wood.
The following instructions only apply to passing the gas line through the fireplace wall. Follow the instructions
provided by the appliance for the gas line, testing and adjusting it.
1. Locate the recessed area in the side refractory panel as shown by Figure 28.
2. Tap out a round hole in the brick liner with a hammer by tapping lightly on the recessed area.
3. Remove the two screws that hold the cover plates on the jacket wrap and discard the cover plate.
4. Use a screwdriver or similar tool to push the loose insulation out of the tube between the firebox and the
outer jacket of the fireplace.
5. Install the gas pipe through the tube between the firebox and jacket.
6. Attach the gas appliance to the gas pipe according to the appliance makers instructions.
7. Pack the insulation removed in step 4 around the pipe to prevent air flowing through the tube either into or
out of the firebox.
8. Be sure the gas is turned off at the appliance, then turn the gas on at the cut off valve and test the gas line
connections for leaks with soapy water solution or a liquid leak detector. DO NOT USE A MATCH OR
OTHER FLAME SOURCE TO CHECK FOR GAS LEAKS. If a gas leak is detected, turn the gas off
immediately and fix the leak.
9. Proceed with testing the appliance for leaks and adjusting it as required by the manufacturer instructions.

FIREPLACE OPERATION
WARNING: If a decorative gas appliance is used in the fireplace the fireplace damper must be fixed in an open
position. (See additional operation information in section titled “Operation Guidelines”.)
ADVANTAGES OF A WOOD BURNING FIREPLACE
These are the practical, ecological advantages of wood as a fuel. Also to be considered is the aesthetic
appeal. Most of us consider a wood fire with nostalgia. We enjoy the aroma, and find the flickering light of a
cozy hearth conductive to a happy remembrance of things past. Wood has a low ash content. And the little
ash that remains after burning is useful in home gardening as a fertilizer and soil conditioner.
WHICH WOODS ARE BEST?
Each wood species offers something different in aroma or heat value, and you should consider your needs and
desires before building your fire.
Softwoods, like pine, spruce, and fir are easy to ignite because they are resinous. However, a fire built entirely
of softwoods burns out quickly and requires frequent replenishment. While a softwood fire is not too desirable
for a long evening, it’s fine in the morning when you want quick warmth, or late in the evening when you want
a fire that will burn out before you go to bed.
On occasion when a longer fire is desired, it’s best to combine softwoods with the heavier hardwoods such as
ash, beech, birch, maple, oak and hickory. These hardwood species burn less rapidly, with shorter flames,
and produce steady, glowing coals.
For the most pleasing aroma, you’ll want to burn the wood of fruit trees such as apple and cherry, or nut trees
such as beech, hickory and pecan. Such wood is generally more expensive, but a little combined with other
wood, goes a long way. Start your fire with a mixture of softwood and hardwood, then add some fruit or nut
wood for nostalgic aroma. Since most woods will not burn well when freshly cut, the wood you purchase
should be reasonably dry. The sizes you buy are dictated by the size of your fireplace. Purchase logs that will
fit when laid across your grate, and ask that the larger, heavier logs be split. Kindling should be short, easily
split lengths of softwood, lumber yard or mill scraps, or twigs and branches gathered from your yard.
HOW TO BUILD A BETTER FIRE
The first three fires should be of moderate size to allow the fireplace to adjust and the bricks to cure before
being subjected to larger fires.
First, make sure your room is well ventilated, your damper open and the flue is unobstructed. Then make sure
your wood is dry and seasoned. Unseasoned wood burns poorly and coupled with poor ventilation or an
obstructed chimney, leads to smoking problems.
If your fireplace is equipped with an outside combustion air assembly, open the combustion air inlet by pushing
upward on the lever located above the firebrick on the left side of the firebox.
NEVER
USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR
SIMILAR LIQUIDS TO START OR "FRESHEN UP" A FIRE IN THIS FIREPLACE. KEEP ALL SUCH LIQUIDS
WELL AWAY FROM THE FIREPLACE WHILE IT IS IN USE. USE OF THIS FUEL CAN CAUSE A SERIOUS
EXPLOSION.
Prepare your fire by placing two logs on the iron grate or fire basket, and laying the tinder between them.
Tinder may be dry scrap paper, twigs, or bark. On top place a small handful of twigs or split softwood kindling.
Place more dry logs over this base. Keep logs close together, as narrow air spaces between them promote
better drafts, and heat reflected between adjacent surfaces aids in raising and maintaining combustion
temperatures.
29
53D9031. Rev 1 03/03
FIREPLACE OPERATION
You’ll need a minimum of three logs, preferably four, to make a good fire. Add kindling and new logs as needed
to rekindle a dying fire. New logs should be added at the rear grate after raking the coals toward the front. DO
NOT OVERFIRE THE FIREPLACE. Overfire conditions may be created by large amounts of kindling, building scraps,
or other improper fuels.
Ashes, important because they form a bed of glowing coals, should only be left to accumulate within an inch or
two of the bottom of the grate. Excess ashes can be used to check a flaming fire; or to “bank” your fire, cover
the logs with ashes. A “banked” fire will hold glowing coals for 8-10 hours, thereby saving a fire for later use.
WOOD VS. FOSSIL FUELS
Compared to fossil fuels, a full cord of dry hickory weighs about two tons and is approximately equal in heating
value to a ton of hard coal. On a pound basis, heavy hardwoods have about half the heating value of coal. The
tabulation shows the relative densities and heat values of a variety of dry woods. Varieties at the top of the list
(Dogwood) burn longer and those near the bottom (White Pine) ignite and burn quicker. A combination of both
light and heavy wood is desired.

A FEW WORDS OF CAUTION
Beware of burning certain material in your fireplace. Among these are plastics, poison ivy twigs and stems,
and chemically treated woods such as discarded poles and railroad ties. These not only create air pollution,
but can induce extreme irritation for some individuals.
Use hemlock, spruce, juniper and other resinous woods with caution. They contain moisture pockets which,
upon heating, “pop” with considerable vigor.
Always use a fire screen. And always “bank” a fire, or at least push all unburned fuel to the rear of the grate
before leaving a fire unattended. Do not use this fireplace as an incinerator.
Because the termination of the chimney above the roof is exposed to wind and cold and the pressure changes
these and other environmental conditions may cause, a sufficient chimney draft may be hard to establish at
times. At other times the draft may be sufficiently disrupted to cause smoke to spill from the fireplace opening.
If problems with chimney draft occur, help start chimney draft before you build a fire by holding a piece of
burning paper near the flue opening at the top of the firebox to preheat the chimney. If smoke spills from the
fireplace opening after the fire is burning, open a window on the up wind side of the house that is far enough
away form the fireplace that the wind will not blow across the fireplace opening, push the burning wood as near
the back of the fireplace as possible, and if the fireplace is equipped with glass doors, close them.
DO NOT LEAVE CHILDREN OR PHYSICALLY OR MENTALLY HANDICAPPED, OR SENILE PERSONS
ALONE WITH A BURNING FIREPLACE.

MAINTENANCE AND SAFETY
FUEL STORAGE
Wood can be dried sufficiently for burning within a few weeks if protected form rain in a low humidity area. It is
far better to cut wood and allow it to dry for a year. In all cases, the wood should be stacked so that both ends
of the sticks are exposed to the air and protected from rain. The drier the wood, the more usable heat produced
by the fire and less likely rapid accumulation of soot and creosote within the chimney is to occur. See the
section of this manual concerning chimney maintenance for information concerning the hazards of soot a
creosote accumulation. Small quantities of wood required for fire tending must be kept at least 30 inches from
the fireplace.
DISPOSAL OF ASHES
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be
placed on a noncombustible floor or on the ground well away from all combustible materials pending final
disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained
in the closed container until all cinder has thoroughly cooled. Ashes should never be placed in a container with
combustible materials.
CHIMNEY MAINTENANCE
Creosote, Formation and Need for Removal: When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively
cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When
ignited, this creosote makes an extremely hot fire.
The chimney should be inspected at least twice a year during the heating season to determine if a creosote
buildup has occurred.
If creosote has accumulated it should be removed to reduce the risk of a chimney fire.
The chimney cap can be removed for inspection, maintenance and cleaning by removing three screws from
the support legs and lifting upward.
When the fireplace is first in use, inspect the chimney frequently and clean the chimney any time an accumulation
is observed on the flue walls. The frequency of these inspections can be increased or reduced appropriately
after a pattern of accumulation has been established. Please note, however, that changes in the outside
environmental conditions such as temperature and humidity or changes in the operation of the fireplace can
lead to rapid buildup of soot and/or creosote.
To clean the chimney, obtain the services of a qualified and reputable chimney sweep, or remove the
accumulation with brushes on wooden or fiberglass poles. Do not use metal pipes, chains, wires, etc., to clean
the chimney because such items can scratch the surface of the stainless steel flue which can shorten the life
of the flue and provide a rough surface for soot particles to attach to.
Be sure to cover nearby furnishing and arrange some method of catching soot and creosote particles that may
fall during the chimney cleaning process. If glass doors are installed on the fireplace, they should be closed.
Extra caution must be used to avoid damage to the flue damper during the cleaning process.
In addition to checking and cleaning the chimney on a regular basis, be sure to inspect the chimney before
starting a fire at the beginning of each heating season. Make sure the chimney is clear from any accumulation
of soot, creosote or any other debris, and that all joints are intact.
Monessen Hearth Systems does not recommend chemical cleaners because some may contain elements
that corrode the metal parts of the chimney or fireplace.

MAINTENANCE AND SAFETY
FIREPLACE MAINTENANCE
At the end of each heating season or when the fireplace will not be in use for an extended time, the ashes
should be removed and the hearth area should be swept as clean as is practical. The slow absorption of
moisture into the ashes over a long period of time could cause a condition which would be corrosive to the
metal fireplace parts.
At the beginning of each heating season, always operate the flue damper and make sure it has not become
stuck from soot, creosote, etc., during the period of inactivity.
Keep the lower and upper grille panels clean and free from dirt and lint accumulation at all times to get the
maximum efficiency from your fireplace.
As you use the fireplace, expansion and contraction will cause minor cracking of the hearth, back, and side
refractory materials. This is normal and unavoidable. If the cracks become large enough or parts dislodge and
metal behind the refractory is exposed, the refractory panels should be replaced with new panels that can be
obtained from you Monessen Hearth Systems fireplace dealer.

53D9032. Rev 1 03/03
OPERATION GUIDELINES
5
As wood is burned in the fireplace, room air enters the lower louvered panel of models BWBC500 and BWBC500I,
or the bottom/side vents on models BWB500 and BWB500I circulates around the firebox. This air circulation cools
the firebox and must not be blocked or restricted in any manner. Blocking the air flow can cause a fire hazard.
When a AK4 combustion air assembly and a combustion air duct are attached to the connecting point on the left side
of the fireplace, combustion air may enter the firebox through a dampered opening behind the left side panel. This
feature reduces the room air used for combustion and prevents excessive heat loss from the room. When the
fireplace is in use, this damper should be open. When the fireplace is not in use, the damper should be closed to
prevent cold air from entering the firebox. The combustion air damper is open when the lever, located on the left side
of the firebox near the top of the left firebrick, is up and closed when the lever is down.
Outside air for combustion is optional unless required by federal, state or local building codes. See the section of
this manual providing the instructions for installation of the combustion air assembly. The design of the fireplace
allows the routing of the combustion air duct downward or horizontally to obtain the outside combustion air. This
permits flexibility in planning your installation. See Figure 27 for typical installation methods. Review the precautions
and recommendations in this manual pertaining to outside combustion air installation.
Glass doors should be installed to receive the maximum benefit from your fireplace. For large fires, the maximum
heating benefit from the fireplace will be obtained with the doors open due to the high amount of radiant heat being
emitted out of the front opening of the fireplace. With a small fire, or before retiring in the evenings, it is best to
operate the fireplace with the doors closed to prevent excessive room air from being drawn up the chimney. When
the doors are open, the mesh screens should be closed to help keep burning embers from popping out of the
firebox.
The fireplace also is equipped with a flue damper, which must be open when the fireplace is in use. The flue damper
control lever is located behind the upper panel and may be locked closed by turning the damper rod and latching it
over the clip provided. The counterweighted damper is operated by simply pushing up to open or pulling down to
close the damper. When the fireplace is not in use, the damper should be closed to prevent cold air form entering
the chimney as well as preventing warm air in the room from escaping up the chimney. NOTE: It is normal for a
small amount of smoke to be released from the upper portion of the fireplace the first few times you use your new
Monessen Hearth Systems fireplace. This results from an oil residue on the metal. Open a door or window to allow
the smoke to escape.
The grate included with this fireplace helps to appropriately locate and contain the burning wood. Failure to use this
grate may cause overheating of parts of the fireplace and allow large pieces of burning wood to roll forward out of the
firebox. If the grate becomes warped or damaged, it must only be replaced with Monessen Hearth Systems 035326
grate.
WARNING: Fireplaces equipped with doors should be operated only with the doors fully open or doors fully closed.
If doors are left partly open, gas and flame may be drawn out of the fireplace opening, creating risks of both fire and
smoke.
All fireplace chimneys are in direct contact with cold air on the exterior of the structure. Consequently, when the
fireplace is not in use, cold air can fall down the chimney of the fireplace to cool off the fireplace chase. Therefore,
the fireplace chase must be insulated to minimize the risk of cold air infiltration to the home. Even if the fireplace
chase is adequately insulated, this cannot completely ensure that cold air infiltration into the structure will be eliminated.
Cold air infiltration is a possibility with any fireplace or device that freely communicates with the air on the outside of
the structure. Today’s homes are more energy-efficient and, therefore, better insulated and tightly constructed.
Unfortunately, when air is removed from the house, as by a bathroom fan, or consumed by a furnace, additional air
is needed to replace the air consumed. Unless the additional air is supplied, this can cause a negative pressure in
the home. When this happens, the house will draw in outside air from the cracks in the windows, down the fireplace
flue or other locations of air leakage in the home. Because cold air infiltration may be unavoidable in some structures,
Monessen Hearth Systems is not responsible for heat loss or air infiltration through or around the fireplace.

FIREPLACE LOCATION
CAUTION: Do not install fireplace over carpeting.
This fireplace does not weigh more than large pieces of furniture and can normally be located near a load
bearing wall without requiring additional foundations or supports. If however, the fireplace is to be trimmed
with a heavy stone or brick facing and hearth extension, be sure the supporting structure is adequate.
Figures 4 and 5 provide dimensional details of the fireplace, required spacing to combustible walls, and some
suggested fireplace locations. When selecting a location, choose one that is away from frequently opened
doors, central heat outlets or returns, or other places where air movements may disturb the airflow around the
fireplace. Air turbulence near the fireplace may cause smoke to spill out of the fireplace opening.

INSTALLATION PREPARATION
Survey the planned location for the fireplace for overhead plumbing or electrical wires, etc., that might complicate
the installation or endanger persons installing or cleaning the chimney. Avoid a location where the chimney
cap will be near abrupt changes in the roof shape, nearby wall or embankments, under or near trees or above
the roof of a single story wing of a two story building as shown by Figure 8. All these conditions can cause
turbulence or pressure conditions that can cause poor chimney draft and smoke spillage from the fireplace
opening. Elbows may be used to offset the chimney to avoid obstructions or to locate the chimney cap in a
preferred location. Refer to the sections of this manual pertaining to chimney offsets for instructions on proper
elbow use. Poor installation or location of the chimney cap and/or components can cause wind blown rain to
enter the chimney.
Be sure the selected location will allow a 14-1/2" square combustible material-free space for the chimney to
pass through. If the chimney is to pass through living or storage spaces, be sure there is adequate space to
enclose the chimney to avoid personal contact with, or damage to, the chimney. If the fireplace is to be
installed on an outside wall, the surrounding walls (chase) should be constructed and insulated as shown by
Figure 6. Failure to insulate the fireplace from outside temperatures will cause heat loss through and around
the fireplace.

FLOOR PROTECTION
If this fireplace is installed on a combustible floor, the floor area 20 inches in front of, and 12 inches either side
of the fireplace opening must be protected by an insulating noncombustible hearth extension. This hearth
extension may be either minimum 6-inch thick stone or brick as shown by Figure 10, an H2066 Hearth Extension
Kit or a locally constructed hearth equivalent to the H2066.
The insulation used in the H2066 hearth extension has a thermal conductivity (K Factor) of .43. If you do
construct a hearth extension equivalent to the H2066, be sure the insulation you use has enough compressive
strength to support the weight of the covering materials and persons standing on it, and insulating qualities
equal too or better than the ˚" covering provided by the H2066.

The ability of insulating material to retard the transfer of heat may be expressed as either Thermal Conductance (C), Thermal Conductivity (K), or Thermal Resistance (R). The mathematical relationship of these
values and the formulas for converting one value to another is as follows:
FIGURE 11
C = K divided by the material thickness
(Example C = .43 divided by 1/2 (.50)
C = .86)
K = C multiplies by the material thickness
(Example K = .86 multiplied by 1/2 (.50)
K = .43)
R = The material thickness divided by K
(Example R = 1/2 (.50) divided by .43
R = 1.16)

METAL SAFETY STRIP
With either type hearth extension minor shifting of the supporting floor or expansion and contraction may
eventually cause a crack to develop between the hearth extension and the face of the fireplace. To help
prevent the crack from developing, the hearth extension materials must be firmly fastened in place. Wall ties
should be screwed to the face of the fireplace and imbedded in the mortar joints of brick, stone, or other noncombustible materials. The metal safety strip packed with the fireplace must be placed beneath the fireplace
and extended under the hearth extension or into a mortar joint of the hearth extension as shown by Figures 10,
11, and 12. In the event a crack does eventually develop, the metal safety strip will serve as a barrier to
prevent sparks or embers from falling from the fireplace onto combustible flooring materials.
The hearth extension must not block the side air vents, or air inlet louvers on the lower front of the fireplace.
These openings must be unobstructed to assure an adequate flow of cooling air around the firebox. If the
fireplace is equipped with a blower, or may be equipped with one at a later date, the hearth extension must not
prevent the removal of the lower louver panel for servicing the blower. Plan adequately by determining the
finished height of the hearth extension to be used and elevate the fireplace on a platform, if necessary, to
prevent obstructing the air openings or lower louvered panel.

FIREPLACE INSTALLATION
LOCATION SELECTION
Unpack and check the fireplace and chimney for damage. If any items have been damaged, report this to your
dealer. Before beginning the installation, be sure you have the proper parts in sufficient quantity. Refer to the
Parts Diagram and List section of this manual for proper identification of parts.
Do not substitute parts. Use only parts listed for use with Monessen Hearth Systems Models BWB500, BWB500I,
BWBC500, and BWBC500I fireplaces.
FIREPLACE INSTALLATION
1. Refer to Figure 1 for an example of a typical installation of the fireplace components.
2. Be sure the location of the fireplace will provide the required clearances indicated by Figures 1, 2, 4, & 5
and the minimum chimney air space clearance to combustibles of two inches.
3. Set the fireplace in the desired location and be sure it is securely supported and leveled. Check the face
of the fireplace with a carpenter’s level and if it is not plumb; correct it by placing shims under the edges of
the fireplace.
4. Block in the fireplace to prevent any shifting of the firebox. Secure the fireplace with nails or screws
through the flanges located on each side of the fireplace. Do not enclose the fireplace until the combustion
air duct and chimney pipes are installed.
NOTE: Some local codes may require electrically grounding the fireplace and chimney.
CHIMNEY INSTALLATION
In order to assure safe and satisfactory performance of the fireplace, it is very important to properly install the
chimney. This is an important part of the installation and the sections of this manual pertaining to chimney
installation should be reviewed very thoroughly.
For your safety, some of the important things to remember in regard to chimneys are listed below:
1. Use only parts and accessories labeled for use with this fireplace.
2. Use only undamaged parts and accessories.
3. Enclose the chimney where it passes through the living spaces to prevent contact with and possible damage
to the chimney.
4. Install firestop spacers at each ceiling level.
5. Install the proper chimney cap or chimney housing on the chimney to prevent the entry of rain and debris
into the chimney and to assure the proper venting of smoke.
6. Do not use more than four elbows in the chimney.
NOTE: To select the proper chimney height, refer to Figures 1, 7, 9, and 14. The flue outlet must be a
minimum of three feet above the highest point where the chimney penetrates the roof and a minimum of two
feet above all portions of the building within ten feet. If the chimney is to include elbows to offset the chimney,
refer to the Chimney Offset and Cap Installation section of this manual. There must be at least two inches air
space between all sections of the chimney and combustible materials between floors.

1. Lay out, cut and frame openings through all ceilings and the roof at the point where the chimney will pass
through. Unless the chimney is to be offset, the point where the center line of the chimney will pass
through the ceiling and roof can be determined with a plumb line as shown by Figure 15. The fireplace
should be located in the planned installation position. After the center line is established and a nail is
driven to mark the point, the opening can be cut if you are satisfied with the chimney location relative to
ceiling and roof joists and/or any other obstructions. The roof opening center line should be marked by
driving a nail through the roof from underneath that will penetrate the roof and can be located from the
rooftop. If the chimney is to penetrate a pitched roof, the hole in the roof must be rectangular instead of
square and should be sized according to Table1.
2. Install the firestop spacer as required from beneath the ceiling unless the space above is attic space. In an
attic, the firestop spacer should be installed at the floor level of the attic. Figure 17. You must have joists
or headers on all four sides of the spacer and use a minimum of four 8-penny nails to secure the spacer.
3. To install the “S” series chimney sections, insert the male end of the flue, the smallest diameter pipe, into
the flue outlet of the fireplace and press down until the snap locks engage. Continue the process, adding
the chimney sections on top of each other until the chimney is at least six inches above the roof opening on
all sides. As the chimney sections are installed, check each joint to make sure it is properly locked to the
previous section. If additional strength of the outer pipe joints is desired, you may use two or three sheet
metal screws placed through the area where the outer pipes overlap one another. To install these screws,
drill a 1/8-inch diameter hole through the chimney sections, taking care not to penetrate the inner flue pipe.
Warning: Be very careful when drilling the holes into the outer pipe. The drill must not penetrate the inner
stainless steel pipe.
NOTE: If you intend to have a total fireplace installation of more that 30 feet you must use chimney support
model SCS at or below 30 feet to support the weight of additional chimney pipe.
To install the chimney support, place the crimped end of the flue and outlet air duct portions into the last section
of chimney pipe. Push down until the outside or inlet air duct of the chimney support overlaps and snap locks
the chimney support into the chimney section.
Nail the support straps tightly to a building frame member or ceiling joist as shown by Figure 16. You must use
at least two 8-penny nails per strap.

ELBOW INSTALLATION
The following are important points that should be observed when installing elbows on the fireplace:
1. The support straps of all elbows not installed directly on top of the fireplace should be nailed securely to the
surrounding structure. This allows the support strap to carry the weight of the chimney above the elbow
and prevents this weight from breaking the elbow or chimney sections apart. Figure 18.
2. Elbows should not be used in any combination that inclines the chimney more than 30 degrees from
vertical.
FIGURE 18

3. The limitations on the quantity of elbows per chimney are as follows: If the total height of the fireplace and
chimney is — 14' 0" or more — two elbows may be used in the chimney. 21' 0" or more — four elbows
may be used in the chimney.
4. The inclined portions of chimneys that pass through living spaces likely to be used for storage should be
enclosed to avoid contact with and possible damage to the chimney. The minimum air space of two inches
between the chimney and enclosing materials must be maintained. Figures 20 and 21 illustrates elbow
installations.
5. The length of the inclined portion of chimney between elbows must not exceed 6 feet when unsupported or
20 feet if the chimney is supported at six-foot intervals with support such as metal support straps.
6. When enclosing the elbows and inclined portions of the chimney, enclosing materials must be installed
vertically to maintain the required two-inch minimum air space clearance to the chimney at the extremities
of the offset. It is recommended that enclosing material not follow the inclined portions of the chimney.
OFFSET INSTALLATION SEQUENCE
1. Determine the location and amount of offset required, then select the combinations of chimney sections
and elbows required from the offset chart. Refer to Table 2.
2. Install the first SE30 elbow by placing the extended flue into the mating part of the fireplace or chimney
section. Push down until the outside or inlet air duct of the elbow overlaps and the snaps lock the elbow
into the fireplace or chimney section.
3. Nail the support straps to the framing member with a minimum of two 8-penny nails per strap.
4. Install the sections of pipe between elbows until the proper number of chimney sections have been installed.
5. Install the second elbow to return the run of the chimney to vertical.
6. Nail the support straps of the second elbow to a building frame member.
7. Continue installing the vertical portion of the chimney.
NOTE: If the inclined portion of the chimney passes through a floor or ceiling, an SF firestop spacer should be
installed to provide the firestop and support required. Be sure proper spacing in maintained between the
chimney and combustibles. Figure 19.

SPECIAL NOTE: The proper height as previously explained is important to assure proper draft and safety. The
chimney cap extends the flue outlet four inches above the top of the last section of chimney. This should be
kept in mind when determining the proper height for the chimney. The chimney should not be extended more
than 90 inches above the supporting roof structure without additional support. In the case of an “A” frame type
construction or other steep pitch roofs that require more than 90 inches of chimney above the roof, a support
should be attached to the chimney at the 90 inch level that is strong enough to support a wind load of 3-1/8
pounds for each inch the chimney extends above 90 inches. The flue outlet must be a minimum of three feet
above the point where in penetrates the roof. Figure 14.
CAUTION: Be careful to avoid electrical shock hazard when contacting wires to the metal chimney components.
1. Extend the regular chimney sections until the top of the chimney is 4 inches below the total flue height
desired. Do not snap the last section of inlet air duct or largest diameter pipe in place until Step 3 is
completed.
2. Remove the shingles from around the chimney so that the flashing may be installed, with the upper part of
the flashing under the shingles.
3. Set the flashing on the roof and scribe a line around the flashing, then cut the top off the flashing by cutting
1/4 inch below the scribed line. This should increase the diameter of the flashing outlet sufficiently to allow
the flashing to be placed over the chimney. See Figure 22.
4. Snap the last section of inlet air duct in place and slide the flashing over the chimney. Adjust the chimney
to assure that the proper minimum clearances are maintained.
5. Nail the flashing securely in place with eight nails.
6. Seal the crack between the top of the flashing and the chimney with mastic. Leave some excess mastic at
this area to be used in step eight. NOTE: Use pliers and wear gloves when performing step seven to
minimize the danger of cutting your hands on the edge of the storm collar.
7. Place the storm collar around the chimney and put the collar together like a belt in belt loops. Slide the end
of collar under the two loops on the other end with the loops facing up. Overlap the ends of the collar until
it is tight against the chimney. Bend the free end of the collar back over the loops to hold the storm collar
securely together. The excess end of the storm collar may be trimmed off.
8. Slide the storm collar down snugly against the flashing until the excess mastic left in step six is forced up
into the crack between the storm collar and the chimney. This should make the joint between the flashing
and the chimney watertight.
9. Install the chimney cap by placing the cap into matching parts of the last chimney section. Push down until
the brackets on the bottom of the chimney cap sits on the chimney pipe. Then punch or drill 1/8 inch
diameter holes in the inlet air duct (chimney pipe) where specified on the brackets and fasten it down with
the No. 8 screws provided. Do not penetrate the inner stainless steel pipe while installing the screws.
10. Check all the parts of the fireplace, chimney and chimney termination cap to assure that no parts have
been damaged or bent during installation and that all parts have been installed properly.
NOTE: The metal used for the chimney cap has a rust protective coating but the cut edges of the parts are not
protected. To prevent rusting and rust staining of nearby structures, exposed parts of the chimney and chimney
cap should be detergent washed and painted with a galvanized primer paint.

CHIMNEY CAP CHASE INSTALLATION
The preinstalled chimney sections should be no more than 10 inches below the top of the chase. The installation
should be planned so that either an 18-inch or 36-inch chimney section will be used for the top section. This
is necessary to ensure complete engagement of the inlet air telescope and chimney cap into the top section.
CAUTION: Be careful around electrical wires to avoid the electrical shock hazard of contacting the wires with the
metal chimney components.
NOTE: When two fireplace chimneys are terminated above the same chase, the centers of the chimney caps
should be at least 24 inches apart to help prevent smoke from a fireplace in use from being drawn down the
chimney of a fireplace that is not in use. Additional spacing between caps or staggering the height of the caps
will further lessen the likelihood of this occurring.
1. Extend the chimney sections until the top of the chimney is not more than 10 inches below the top of the
chase.
2. Center the hole in the chase cover over the chimney. The chase cover overhang should be lanced, formed
over the chase and secured with nails. This prevents water from seeping under the chase cover. If two or
more chase covers are to be used on the same chase, they should be soldered together to form two
watertight seams.
3. Place the inlet air telescope inside the hole in the chase cover and lower it down into the mating pipe of the
chimney until the flange on the telescope section rest on the flange of the chase cover. Note: All telescoping
sections should extend a minimum of three inches inside the mating chimney pipes.
4. Install the SCL or SQL8 chimney cap by placing the cap into the matching duct telescope and flue telescope
of the last chimney section as shown by Figure 23. Lower the cap until the brackets on the bottom of the
chimney cap rests on the raised flange of the flat flashing, punch or drill 1/8 inch diameter holes in the
raised flange of the flat flashing, and fasten the cap to the flashing with the No. 8 screws provided.
5. Check all parts of the chimney and chimney cap to assure that no parts have been damaged or bent during
installation and that all parts have been installed properly.
NOTE: The metal used for the chimney and chimney cap has a rust-protective coating but the cut edges of the
parts are not protected. To prevent rusting and rust staining of nearby structures, exposed parts of the chimney
and chimney cap should be detergent-washed and painted with galvanized primer paint.

1. Push the insulation back approximatly 2"
from the end of each duct .
2. Slip each duct over the duct connector until
an equal length of the connector extends into
each duct.
3. Place a duct clamp over the end of each duct
and tighten it down snuggly.
4. Push the insulation back into place and over
the duct clamp.
OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS
OUTSIDE COMBUSTION AIR RECOMMENDATIONS (CONTINUED)
1. Extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air
assembly should be avoided. These conditions will increase the resistance to the free flow of air through
the duct. Refer to Figures 1 and 27 for methods of installing the outside air for combustion assemblies.
2. The combustion air assembly should be located at an exterior location, which is not likely to be accidentally
blocked in any manner. The assembly should be located above the snow line to prevent blockage by snow
accumulation.
3. The combustion air inlet assembly should never be mounted in a garage or storage area where combustible
fumes such as gasoline might be drawn into the fireplace.
4. Combustion air can be drawn from the crawl space under a house when an adequate supply of air is
provided by open ventilation.
5. Do not take combustion air from attic space or garage space.

MODEL AK4 COMBUSTION AIR ASSEMBLY
1. Remove the cover plate from the 4-inch outlet opening location on the left or right outside of the fireplace.
DO NOT remove the cover if the outside air will not be connected.
2. Place the insulation ring between the AK4 starting collar and fireplace wall and place the starting collar (4
inch) into the hole on the side of the fireplace. Fasten it in place with the four sheet metal screws provided.
Figure 24.
3. Cut a 5-inch diameter opening for model AK4 in the outside wall covering where the outside vent is to be
located. Figure 25.
4. Select and cut a piece of duct sufficient length to attach to the fireplace and protrude at least three inches
beyond the face of the wall to which the AK4 inlet air vent will be attached. The duct may be cut with a
standard pocket knife (use FP-4 U duct for maximum efficiency and safety). Do not use a combustible
duct. Always use UL Listed Class 0 or 1 duct material.
5. If the duct is the insulated type, push the insulation back from one end of the duct approximately two
inches. Figure 26.
6. Slip the exposed end of the duct over the starting collar on the fireplace.
7. Using the sheet metal screws provided, secure the duct end to the collar attached to the fireplace.
8. Nail or screw the combustion air assembly to the surface of the wall.
NOTE: If the wall covering is brick or stone, use appropriate masonry fasteners. Mount the combustion air
assembly with “TOP’” upward to prevent cold air from entering through the wall. If it is necessary to splice the
duct, a model 403 duct connector should be used to splice duct sections.

GAS APPLIANCE INSTALLATION
WARNING: Improper installation or operation of a gas appliance in this fireplace can allow unburned gas to leak
out which will cause a fire or explosion hazard, or the release of poisonous carbon monoxide into the dwelling
which can cause serious injury or death to its inhabitants. To reduce these risks to a minimum, the following
important notices and instructions should be read and followed carefully.
IMPORTANT NOTICES:
1. The provision for a gas line is intended for connection to a decorative gas appliance which has an automatic
shutoff device and complies with the Standard for Decorative Gas Appliances for Installation in Vented
Fireplaces, ANSIZ21.60. If a decorative gas appliance is installed, it must be installed in accordance with
the National Fuel Gas Code, ANSIZ223.1.
CAUTION: When a decorative gas appliance is installed, the fireplace damper must be set in the fully open
position at all times.
CAUTION: If an unvented gas appliance is installed in the fireplace, the gas appliance must only be operated
with the fireplace glass door fully open, if glass doors are installed on the fireplace.
WARNING: Do not operate an unvented gas log set in the fireplace with the chimney removed.
The installer of the fireplace and gas appliance must describe the operation of the fireplace and appliance
to the people who will be operating them and leave all instruction manuals with the operator of the appliance.
2. An approved gas shut off valve must be located outside the fireplace in an area accessible to the users of
the fireplace.
3. All gas piping and fitting must be either steel or malleable iron. Unions must be of the ground joint type.
4. Some code authorities prohibit or place restrictions on the use of gas appliances in fireplaces. Check with
local code authorities before proceeding with the installation.
5. The gas appliance and all connecting gas piping should only be installed by a licensed gas appliance
installer. See Figure 28 for the gas line opening dimensions on the fireplace.
6. The installer should advise the persons who will use the appliance to set the fireplace damper in the full
open position when the appliance is in use.
The following instructions only apply to passing the gas line through the fireplace wall. Follow the instructions
provided by the appliance for the gas line, testing and adjusting it.
1. Locate the recessed area in the side refractory panel as shown by Figure 28.
2. Tap out a round hole in the brick liner with a hammer by tapping lightly on the recessed area.
3. Remove the two screws that hold the cover plates on the jacket wrap and discard the cover plate.
4. Use a screwdriver or similar tool to push the loose insulation out of the tube between the firebox and the
outer jacket of the fireplace.
5. Install the gas pipe through the tube between the firebox and jacket.
6. Attach the gas appliance to the gas pipe according to the appliance maker’s instructions.
7. Pack the insulation removed in step 4 around the pipe to prevent air flowing through the tube either into or
out of the firebox.
25
53D9032. Rev 1 03/03
GAS APPLIANCE INSTALLATION
8. Be sure the gas is turned off at the appliance, then turn the gas on at the cut off valve and test the gas line
connections for leaks with soapy water solution or a liquid leak detector. DO NOT USE A MATCH OR
OTHER FLAME SOURCE TO CHECK FOR GAS LEAKS. If a gas leak is detected, turn the gas off
immediately and fix the leak.
9. Proceed with testing the appliance for leaks and adjusting it as required by the manufacturer instructions.

APPLYING DECORATIVE TRIM TO THE FIREPLACE
Do not allow the trim materials to extend closer than 3/8 inch to the vertical edges of the firebox opening if you
plan to equip the fireplace with glass doors.
The face of your fireplace may be left exposed or trimmed with any noncombustible material such as brick,
stone or marble. See Figure 29. If a trim is installed, be sure it is fastened snugly to the face of the fireplace.
A crack between the material and the face of the fireplace could pose a fire hazard and impair the proper
operation of the fireplace. Blocking the fireplace with framing and attaching the base to the supporting floor will
further reduce the possibility of such a crack developing.
Wall ties should be fastened to the face of the fireplace with sheet metal screws and placed in the mortar joints
of masonry trim.
Combustible material must not be installed below the top spacers of the fireplace or overlap the sides of the
fireplace face. Figures 30 and 31. Seal the face of the fireplace to the surrounding wall with non-combustible
caulk or trim materials to prevent cold air leakage around the fireplace.
The trim should not block or restrict in any way the flow of air into the side air inlets in the face of the fireplace.
Be sure to provide the required floor protection as described in a preceding section of this manual.
Combustible mantles and trim must be installed in accordance with the National Fire Protection Association ANSI NFPA 211 Standard - Section 7-2.3.3.

FIREPLACE OPERATION
WARNING: If a decorative gas appliance is used in the fireplace the fireplace damper must be fixed in an open
position. (See additional operation information in section titled “Operation Guidelines”.)
ADVANTAGES OF A WOOD BURNING FIREPLACE
These are the practical, ecological advantages of wood as a fuel. Also to be considered is the aesthetic
appeal. Most of us consider a wood fire with nostalgia. We enjoy the aroma, and find the flickering light of a
cozy hearth conductive to a happy remembrance of things past. Wood has a low ash content. And the little
ash that remains after burning is useful in home gardening as a fertilizer and soil conditioner.
WHICH WOODS ARE BEST?
Each wood species offers something different in aroma or heat value, and you should consider your needs and
desires before building your fire.
Softwoods, like pine, spruce, and fir are easy to ignite because they are resinous. However, a fire built entirely
of softwoods burns out quickly and requires frequent replenishment. While a softwood fire is not too desirable
for a long evening, it’s fine in the morning when you want quick warmth, or late in the evening when you want
a fire that will burn out before you go to bed.
On occasion when a longer fire is desired, it’s best to combine softwoods with the heavier hardwoods such as
ash, beech, birch, maple, oak and hickory. These hardwood species burn less rapidly, with shorter flames,
and produce steady, glowing coals.
For the most pleasing aroma, you’ll want to burn the wood of fruit trees such as apple and cherry, or nut trees
such as beech, hickory and pecan. Such wood is generally more expensive, but a little combined with other
wood, goes a long way. Start your fire with a mixture of softwood and hardwood, then add some fruit or nut
wood for nostalgic aroma. Since most woods will not burn well when freshly cut, the wood you purchase
should be reasonably dry. The sizes you buy are dictated by the size of your fireplace. Purchase logs that will
fit when laid across your grate, and ask that the larger, heavier logs be split. Kindling should be short, easily
split lengths of softwood, lumber yard or mill scraps, or twigs and branches gathered from your yard.
HOW TO BUILD A BETTER FIRE
The first three fires should be of moderate size to allow the fireplace to adjust and the bricks to cure before
being subjected to larger fires.
First, make sure your room is well ventilated, your damper open and the flue is unobstructed. Then make sure
your wood is dry and seasoned. Unseasoned wood burns poorly and coupled with poor ventilation or an
obstructed chimney, leads to smoking problems.
If your fireplace is equipped with an outside combustion air assembly, open the combustion air inlet by pushing
upward on the lever located above the firebrick on the left side of the firebox.
NEVER
USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR
SIMILAR LIQUIDS TO START OR "FRESHEN UP" A FIRE IN THIS FIREPLACE. KEEP ALL SUCH LIQUIDS
WELL AWAY FROM THE FIREPLACE WHILE IT IS IN USE. USE OF THIS FUEL CAN CAUSE A SERIOUS
EXPLOSION.
Prepare your fire by placing two logs on the iron grate or fire basket, and laying the tinder between them.
Tinder may be dry scrap paper, twigs, or bark. On top place a small handful of twigs or split softwood kindling.
Place more dry logs over this base. Keep logs close together, as narrow air spaces between them promote
better drafts, and heat reflected between adjacent surfaces aids in raising and maintaining combustion
temperatures.
29
53D9032. Rev 1 03/03
FIREPLACE OPERATION
You’ll need a minimum of three logs, preferably four, to make a good fire. Add kindling and new logs as needed
to rekindle a dying fire. New logs should be added at the rear grate after raking the coals toward the front. DO
NOT OVERFIRE THE FIREPLACE. Overfire conditions may be created by large amounts of kindling, building scraps,
or other improper fuels.
Ashes, important because they form a bed of glowing coals, should only be left to accumulate within an inch or
two of the bottom of the grate. Excess ashes can be used to check a flaming fire; or to “bank” your fire, cover
the logs with ashes. A “banked” fire will hold glowing coals for 8-10 hours, thereby saving a fire for later use.
WOOD VS. FOSSIL FUELS
Compared to fossil fuels, a full cord of dry hickory weighs about two tons and is approximately equal in heating
value to a ton of hard coal. On a pound basis, heavy hardwoods have about half the heating value of coal. The
tabulation shows the relative densities and heat values of a variety of dry woods. Varieties at the top of the list
(Dogwood) burn longer and those near the bottom (White Pine) ignite and burn quicker. A combination of both
light and heavy wood is desired.

A FEW WORDS OF CAUTION
Beware of burning certain material in your fireplace. Among these are plastics, poison ivy twigs and stems,
and chemically treated woods such as discarded poles and railroad ties. These not only create air pollution,
but can induce extreme irritation for some individuals.
Use hemlock, spruce, juniper and other resinous woods with caution. They contain moisture pockets which,
upon heating, “pop” with considerable vigor.
Always use a fire screen. And always “bank” a fire, or at least push all unburned fuel to the rear of the grate
before leaving a fire unattended. Do not use this fireplace as an incinerator.
Because the termination of the chimney above the roof is exposed to wind and cold and the pressure changes
these and other environmental conditions may cause, a sufficient chimney draft may be hard to establish at
times. At other times the draft may be sufficiently disrupted to cause smoke to spill from the fireplace opening.
If problems with chimney draft occur, help start chimney draft before you build a fire by holding a piece of
burning paper near the flue opening at the top of the firebox to preheat the chimney. If smoke spills from the
fireplace opening after the fire is burning, open a window on the up wind side of the house that is far enough
away form the fireplace that the wind will not blow across the fireplace opening, push the burning wood as near
the back of the fireplace as possible, and if the fireplace is equipped with glass doors, close them.
DO NOT LEAVE CHILDREN OR PHYSICALLY OR MENTALLY HANDICAPPED, OR SENILE PERSONS
ALONE WITH A BURNING FIREPLACE.

MAINTENANCE AND SAFETY
FUEL STORAGE
Wood can be dried sufficiently for burning within a few weeks if protected form rain in a low humidity area. It is
far better to cut wood and allow it to dry for a year. In all cases, the wood should be stacked so that both ends
of the sticks are exposed to the air and protected from rain. The drier the wood, the more usable heat produced
by the fire and less likely rapid accumulation of soot and creosote within the chimney is to occur. See the
section of this manual concerning chimney maintenance for information concerning the hazards of soot a
creosote accumulation. Small quantities of wood required for fire tending must be kept at least 30 inches from
the fireplace.
DISPOSAL OF ASHES
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be
placed on a noncombustible floor or on the ground well away from all combustible materials pending final
disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained
in the closed container until all cinder has thoroughly cooled. Ashes should never be placed in a container with
combustible materials.
CHIMNEY MAINTENANCE
Creosote, Formation and Need for Removal: When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively
cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When
ignited, this creosote makes an extremely hot fire.
The chimney should be inspected at least twice a year during the heating season to determine if a creosote
buildup has occurred.
If creosote has accumulated it should be removed to reduce the risk of a chimney fire.
The chimney cap can be removed for inspection, maintenance and cleaning by removing three screws from
the support legs and lifting upward.
When the fireplace is first in use, inspect the chimney frequently and clean the chimney any time an accumulation
is observed on the flue walls. The frequency of these inspections can be increased or reduced appropriately
after a pattern of accumulation has been established. Please note, however, that changes in the outside
environmental conditions such as temperature and humidity or changes in the operation of the fireplace can
lead to rapid buildup of soot and/or creosote.
To clean the chimney, obtain the services of a qualified and reputable chimney sweep, or remove the
accumulation with brushes on wooden or fiberglass poles. Do not use metal pipes, chains, wires, etc., to clean
the chimney because such items can scratch the surface of the stainless steel flue which can shorten the life
of the flue and provide a rough surface for soot particles to attach to.
Be sure to cover nearby furnishing and arrange some method of catching soot and creosote particles that may
fall during the chimney cleaning process. If glass doors are installed on the fireplace, they should be closed.
Extra caution must be used to avoid damage to the flue damper during the cleaning process.
In addition to checking and cleaning the chimney on a regular basis, be sure to inspect the chimney before
starting a fire at the beginning of each heating season. Make sure the chimney is clear from any accumulation
of soot, creosote or any other debris, and that all joints are intact.
Monessen Hearth Systems does not recommend chemical cleaners because some may contain elements
that corrode the metal parts of the chimney or fireplace.
31
53D9032. Rev 1 03/03
MAINTENANCE AND SAFETY
FIREPLACE MAINTENANCE
At the end of each heating season or when the fireplace will not be in use for an extended time, the ashes
should be removed and the hearth area should be swept as clean as is practical. The slow absorption of
moisture into the ashes over a long period of time could cause a condition which would be corrosive to the
metal fireplace parts.
At the beginning of each heating season, always operate the flue damper and make sure it has not become
stuck from soot, creosote, etc., during the period of inactivity.
Keep the lower and upper grille panels clean and free from dirt and lint accumulation at all times to get the
maximum efficiency from your fireplace.
As you use the fireplace, expansion and contraction will cause minor cracking of the hearth, back, and side
refractory materials. This is normal and unavoidable. If the cracks become large enough or parts dislodge and
metal behind the refractory is exposed, the refractory panels should be replaced with new panels that can be
obtained from your fireplace dealer.
GLASS DOOR MAINTENANCE
For glass door maintenance, see instructions provided with the glass doors.
