OPERATION GUIDELINES
5
As wood is burned in the fireplace, room air enters the air slot on the lower front edge and circulates around the
firebox.
The air circulation around the firebox serves to cool the fireplace and must not be blocked in any manner.
Blocking of the inlet slot or outlet louver will cause the firebox to reach hazardous temperatures.
When an OAC4 combustion air assembly and a combustion air duct are attached to the connecting point on
the side of the fireplace, combustion air may enter the firebox through a dampered opening behind the side
panel. This feature is designed for your benefit to reduce the room air used for combustion and to prevent
excessive loss of heat 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 side of the firebox 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 for additional information.
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 unique design of the fireplace allows the routing of the combustion air duct downward, horizontally or
upward to obtain the outside combustion air. This permits maximum flexibility in planning your installation. See
figure 22 for typical installation methods. Be sure to review the precautions and recommendations in the
section of this manual pertaining to outside combustion air assembly.
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 Martin Hearth & Heating fireplace. This results from an oil residue on the
metal. Open a door or window to allow the smoke to escape.
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.
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, Martin Hearth & Heating is not
responsible for heat loss or air infiltration through or around the fireplace.

SELECTING A LOCATION
CAUTION: Do not install fireplace over carpeting.
This fireplace does not require any special foundation. If the fireplace is to be trimmed with large stane or brick
facing, an adequate foundation is required to support these materials. Use figures 5 and 6 as a guide for
selecting a location and determining the space required for the fireplace.
The location for the fireplace should be
adjacent to the load bearing wall and away
from objects that will create drafts that could
disturb the normal flow of air into the fire.
Such objects are frequently opened doors
and central heat and air outlets and returns.
See figure 6 which illustrates various types
of locations and installations and figure 1 for
additional information concerning installation
heights, construction details, and methods
of installation.
A location that requires cutting the least
number of joists and rafters for the chimney
installation will simplify and reduce
installation cost. The opening required for
passage of the chimney through the roof,
ceilings and floors must be 17 inches square
as indicated by figures 7 and 8. The 17-inch
square opening provides for the installation
of the model LF-FS-2 firestop spacer in a
residential installation.
Since the pitch of the roof influences the
opening size required at the roof level, table
1 should be used as a guide for sizing the
roof opening.
Proper selection of a chimney outlet location is also important. Objects such as overhanging or nearby trees,
adjacent building or embarkments or unusual roof designs can all create air turbulance and interfere with
chimney performance and cause the fireplace to spill smoke into the room.
A factory-built fireplace, properly installed in a single story wing of a multi-story builing as shown by figure 9,
may be affected by environmental factors that will cause poor chimney draft and occasional spillage of smoke
from the fireplace opening. Although this occurs infrequently, location of the fireplace in the preferred location
as indicated by figure 9 is recommended.
If the chimney is to pass through living areas or spaces used for storage, be sure that it will be possible to
enclose the chimney to prevent contact with and possible damage to the chimney. Elbows may be used to
avoid obstructions such as electrical wires, water, or sewer pipes, attic fans, heating ducts, etc. Refer to the
section of this manual concerning chimney offsets for proper elbow installation and use.
If the fireplace is to be installed in an outside wall, the surrounding walls should be enclosed and insulated.
failure to properly enclose the fireplace will cause a heat loss and diminish the fireplace efficiency due to
transfer of heat through the fireplace to the outside.

53D9041. Rev 1 03/03
FLOOR PROTECTION
All fireplaces installed over a combustible floor must incorporate a non-combustible hearth extension. It is
required to protect the floor in front of the fireplace from both radiant heat and sparks.
Hearth extension dimensions should be determined by using the chart below. use hearth extensions as illustrated in figures 6, 10 and 11 or use an acceptable thickness of a durable non-combustible material with an
equal or greater insulating value than K = .43 Btu in/ft2-HR-Fº, or a thermal resistance that equals or exceeds
R = 1.16. These materials should be covered with a decorative non-combustible veneer.
NOTE: Any non-combustible material with a K factor value that is less than .43, or whose R value is more than
1.16 for 1/2” thick material is acceptable.
HOW TO DETERMINE HEARTH EXTENSION REQUIREMENTS
The following information is provided to determine required thickness for any non-combustible material when
either the K or R values are known. They are expressed as the following: K = Btu-in/ft2-HR-Fº or R = HR-fº/Btu.
These materials should be covered by a decorative non-combustible material such as tile, brick, stone or slate.
To determine the thickness needed for a material other than those listed in the chart, use the following formulas
to calculate that which will be an acceptable equivalent.
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:
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)
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. 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.
* See figure 6A for an alternate hearth extension using brick only.
WARNING: THE CRACK BETWEEN THE HEARTH EXTENSION AND FIREPLACE MUST BE SEALED WITH
A NON-COMBUSTIBLE MATERIAL. WHEN INSTALLING THE HEARTH EXTENSION, BE CAREFUL NOT
TO BLOCK THE HEAT CIRCULATING AIR INLETS (LOUVERS, SLOTS, ETC.). SEE FIGURE 6A.
Wall Protection
A model WS wall shield or an equivalent must be installed when the closed end of the fireplace is closer than
24 inches from a wall perpendicular to the face of the fireplace. (see figures 10 and 11). The WS wall shield
should be attached securely to the wall by driving nails or screws through it into the wall studs. The wall shield
should be covered by a decorative non-combustible material such as brick, tile, slate, etc.
The WS wall shield is constructed by 1 inch of Micore CV230 insulation board, manufactured by U.S. Gypsum
Corporation, covered by a sheet of galvanized metal. An alternate insulating material with a K factor of .43 or
lower can be used. refer to the preceeding section for instructions for selecting an alternate insulating material.
WARNING: IF NOT INSTALLED, OPERATED AND MAINTAINED IN ACCORDANCE WITH THE
MANUFACTURER’S INSTRUCTIONS, THIS PRODUCT COULD EXPOSE YOU TO SUBSTANCES IN FUEL
OR FROM FUEL COMBUSTION WHICH CAN CAUSE DEATH OR SERIOUS ILLNESS AND WHICH ARE
KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM. ALSO, OPERATION, INSTALLATION AND SERVICING OF THIS PRODUCT COULD EXPOSE YOU TO AIRBORN PARTICLES OF GLASS WOOL FIBERS KNOW TO THE STATE OF CALIFORNIA

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 Model MD36I fireplace.
FIREPLACE INSTALLATION
1. Refer to Figure 1 for examples of typical fireplace framing.
2. Be sure the location of the fireplace will provide the required safety clearances as specified by this instruction manual.
3. Set the fireplace in the desired location and be sure it is securely supported and leveled. Install metal
safety strip for hearth extension as shown by Figures 10, 11, and 12. Check the face of the fireplace with
a carpenter’s level to make sure the fireplace is plumb. If it is not plumb, plumb 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. Install chimney and other fireplace components
as needed.
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.
14
53D9041. Rev 1 03/03
CHIMNEY INSTALLATION
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 Figure 1. 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. (see figure 12) 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 Table 1.
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.

53D9041. Rev 1 03/03
CHIMNEY OFFSET INSTALLATION
NOTE: If you intend to have a total fireplace installation of more than 30 feet, you must use a chimney support
at or below 30 feet to support the weight of additional chimney pipe. If it is impossible to nail the chimney
support to the load bearing framing of the builing at the 30 foot level, the chimney support may be installed at
a lower level if the height of the chimney above the support does not exceed 30 feet. Effective height of the
chimney support is 16-3/4 inches. Chimney supports must be installed at 30 foot intervals.
To install the chimney support, place the crimped end of the flue into the last section of chimney pipe (see
figure 15). Push down until the outside or inlet air duct of the chimney support overlpas and snaps 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 15. You must use
at least two 8 penny nails per strap.
ELBOW INSTALLATION
NOTE: If triple wall elbow is to be placed directly to the top of the fireplace, it will be necessary to bend a tab
over located on each of the four inlet air collar brackets. bend these tabs over only when using a triplewall
elbow to start a chimney run. The tabs may be easily bent with your fingers or pliers. See figure 16A.
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. See Figure 16.
2. Elbows should not be used in any combination that inclines the chimney more than 30 degrees from vertical.
3. The limitations on the quantity of elbows per chimney are as follows: If the total height of the fireplace and
chimney is — 16' 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 17 and 18 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 elbow by placing the crimped end 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. See Figure 19.

CHIMNEY CAP INSTALLATION
MODEL SC CHIMNEY CAP
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 it penetrates the roof. See Figure 12.
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 18.
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.

OUTSIDE COMBUSTION AIR PRECAUTIONS & RECOMMENDATIONS
NOTE: The use of outside air for combustion is optional unless required by building codes. It is only
necessary to supply outside combustion air to one side of the fireplace. Use the model OAC4 combustion
air kit.
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. See Figure 22 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.
21
53D9041. Rev 1 03/03
COMBUSTION AIR ASSEMBLY
MODEL OAC4 COMBUSTION AIR ASSEMBLY
1. Remove the cover cap from the 4 inch outlet opening location on the left or right outside surface of the
fireplace. DO NOT REMOVE THE COVER IF THE OUTSIDE AIR WILL NOT BE CONNECTED.
2. Fasten the (4 inch) starting collar over the hole on the left or right side of the fireplace with the four sheet
metal screws provided. (see figure 22).
3. Cut a 6 inch diameter opening for model OAC4 in the outside wall covering where the model OAC4 outside
grille is to be located. (See figure 24).
4. Select and cut a piece of duct of sufficient length to attach to the fireplace and protrude at least three
inches beyond the face of the wall to which the OAC4 inlet air box assembly 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. (See figure 25)
6. Slip the exposed end of the duct over the flange tube of the fireplace.
7. Place the duct clamp around the exposed end of the aluminum duct.
8. Slip the band through the housing, then pull the band tight around the duct.
9. Snap the band locking screw down and tighten it with a screwdriver or nutdriver. (see figure 25)
10.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 rain from entering the assembly. Be sure the 6 inch diameter
opening around the air duct is sealed with insulation material to prevent cold air from entering through the
wall. If it is necessary to splice the duct, a model 403 duct connector should be installed as described by
figure 26.

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, ANSI Z21.60. If a decorative gas appliance is installed, it must be installed in accordance with
the National Fuel Gas Code, ANSI Z223.1.
CAUTION: When a decorative gas appliance is installed, the fireplace damper must be set in the fully open
position at all times.
WARNING: THIS FIREPLACE HAS NOT BEEN TESTED WITH AN UNVENTED GAS LOG SET. TO
REDUCE RISK OF FIRE OR INJURY, DO NOT INSTALL AN UNVENTED GAS LOG SET INTO

GAS APPLIANCE INSTALLATION
TRIM INSTALLATION
The face of your fireplace may be left exposed or trimmed with any noncombustible material such as brick,
stone or marble. See Figure 28. If a noncombustible 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 reduce the possibility of such a crack developing.
CAUTION: Do not allow any 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.
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. 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.
CAUTION: No trim should block or restrict in any way the flow of air into the air inlets in the face of the
fireplace. See Figures 28 and 29
Be sure to provide the required floor protection as described in a preceeding section of this manual. (See
Figure 10).
GLASS DOOR INSTALLATION
This fireplace has been tested and listed for use with Model MGD36B or MGD36PB glass doors. For installation of the Model MGD36B or MGD36PB glass doors, see the instructions provided with the doors.

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”.)
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 its combustion air damper by
pushing upward on the lever located above the firebrick on the corresponding 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.
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.

FIREPLACE OPERATION
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.
27
53D9041. Rev 1 03/03
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.
Martin Hearth & Heating does not recommend chemical cleaners because some may contain elements that
corrode the metal parts of the chimney or fireplace.
28
53D9041. 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 firebrick, and
side firebrick refractory panels inside the fireplace. 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 Martin Hearth & Heating fireplace dealer. See Figure 34.
