warnings
INSTALLER
• Read this owner’s manual carefully and completely before trying to assemble, operate,
or service this fireplace.
• Any change to this fireplace or its controls can be dangerous.
• Improper installation or use of this fireplace can cause serious injury or death from
fire, burns, explosions, electrical shock and carbon monoxide poisoning.
This fireplace is a vented product. This fireplace must
be properly installed by a qualified service person. The
glass door must be properly seated and sealed. If this
unit is not properly installed by a qualified service person
with glass door properly seated and sealed, combustion
leakage can occur.
CARBON MONOXIDE POISONING: Early signs of
carbon monoxide poisoning are similar to the flu with
headaches, dizziness and/or nausea. If you have these
signs, the fireplace may not have been installed properly.
Get fresh air at once! Have the fireplace inspected and
serviced by a qualified service person. Some people
are more affected by carbon monoxide than others.
These include pregnant women, people with heart or
lung disease or anemia, those under the influence of
alcohol, and those at high altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor
added to these gases can fade. Gas may be present
even though no odor exists.
Make certain you read and understand all warnings.
Keep this manual for reference. It is your guide to safe
and proper operation of this fireplace.

along with adequate accessibility clearance for
servicing and proper operation.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is normal for fireplaces fabricated of steel to
give off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is not unusual for gas fireplace to give off some
odor the first time it is burned. This is due to the
manufacturing process.
Please ensure that your room is well ventilated
during burn off — open all windows.
It is recommended that you burn your fireplace for
at least ten (10) hours the first time you use it. Place
the fan switch in the “OFF” position during this time.

installation planning
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
for horizontal termination
Select the amount of vertical rise desired. All horizontal run
of venting must have 1/4" rise for every 12" of run towards
the termination. With 71/2 feet or more vertical rise off top of
fireplace, the horizontal run may run level. NEVER run vent
piping downward.
warning
It is important to select the proper length of vent pipe for the type of termination you choose. It is also important
to note the wall thickness.
Never run the vent pipe
downward. This may cause
excessive temperatures which
could cause a fire.
You may use up to three 90° elbows in this vent configuration.
See Horizontal Termination Configurations on pages 21 and 22.
For vertical termination
Measure the distance from the fireplace floor to the ceiling. Add the ceiling thickness, the vertical rise in an attic
or second story, and allow for sufficient vent height above the roof line.
NOTE: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using
45° elbows. The appliance is approved for use with three 90° elbows maximum or a combination of 90°
and 45° elbows up to a maximum of 270°.
For two-story applications, firestops are required at each floor level. If an offset is needed in the attic, additional
pipe and elbows will be required.
You may use a chase with a vent termination with exposed pipe on the exterior of the house. See Installing Vent
System in a Chase below. If pipe is enclosed in chase, it is not exposed.
It is very important that the venting system maintain its balance between the combustion air intake and the flue
gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.
Installing a vent system in an outside chase
NOTICE
Treatment of firestops and construction of the chase may vary from building type to
building type. These instructions are not substitutes for the requirements of local
building codes. You must follow all local building codes.
NOTICE
A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a building. A chase
is required for such venting.
When installing in a chase, you should insulate the chase as you would the outside
walls of your home. This is especially important in cold climates. Insulation
should be considered a combustible material. Maintain proper clearances to all
combustible materials.

69D0023
Always maintain minimum clearances around vent systems. The minimum clearances to
combustibles for horizontal vent pipe are 3" at the top* and 1" at the sides and bottom
of the vent system until the pipe penetrates the nearest vertical wall (1" required). A
1" minimum clearance all around the pipe must be maintained at outside wall and on
vertical runs. Do not pack the open air spaces with insulation or other materials. This
could cause high temperatures and may present a fire hazard.
* Unless the vertical run is 71/2 feet or higher (top vent units only), the clearances for

The Vent Graph should be read in conjunction with the following vent installation instructions to determine the relationship
between the vertical and horizontal dimensions of the vent
system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimension
on the Sidewall Vent Graph below, locate the point intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical line to
the bottom of the graph.
3. Select the indicated dimension, and position the fireplace
in accordance with same.
Example: If the vertical dimension from the floor of the
fireplace is 11' (3.4 m) the horizontal run to the face of
the outer wall must not exceed 14' (4.3 m).
Example: If the vertical dimension from the floor of the
unit is 7’ (2.14 m), the horizontal run to the face of the
outer wall must not exceed 81/2' (2.6 m).

Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust,
certain limitations as to vent configurations apply and must be
strictly adhered to.
The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions
allowable. Figure 20
NOTE: Horizontal sections of this vent system require a minimum of 3"
clearances to combustibles at the top of the flue unless the vertical run is
71/2 feet or higher (top vent units only), the clearances for the horizontal
run is 1" at the top, and 1" clearance at the sides and bottom until the
flue penetrates the outside wall. A minimum 1" clearance all around the
flue is acceptable at this point of penetration.
Vertical sections of this vent system require a minimum of 1" clearance
to combustibles on all sides of the pipe.
WARNING
When vent exits through foundations less than 20" below outcrop, the
termination must be flush up with outcropped wall above.
It is best to locate the fireplace in such a way that minimizes the number
of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent pipe from the
flue collar of the fireplace (or the top of the Transition Elbow) to the
face of the outer wall.

Below Grade Installations
When it is not possible to meet the required vent terminal clearances of 12" above grade level, a snorkel kit is
recommended. It allows installation depth down to 7" (178 mm) below grade level. The 7" (178 mm) is measured
from the center of the horizontal vent pipe as it penetrates through the wall.
Ensure that sidewall venting clearances are observed. If venting system is installed below ground, we recommend a window well with adequate and proper drainage to be installed around the termination area.
If installing a snorkel, a minimum 24" vertical rise is necessary. The maximum horizontal run with the 24” vertical pipe is 36". This measurement is taken from the collar of the fireplace (or transition elbow) to the face of the
exterior wall. See the Sidewall Venting Graph for extended horizontal run if the vertical exceeds 24".
1. Establish vent hole through the wall. Figure 16, page 18
2. Remove soil to a depth of approximately 16" below base of snorkel. Install drain pipe. Install window well (not
supplied). Refill hole with 12" of coarse gravel leaving a clearance of approximately 4" below snorkel. Figure
26
3. Install vent system.
4. Ensure a watertight seal is made around the vent pipe coming through the wall.
5. Apply high temperature sealant caulking (supplied) around the 4" and 7" snorkel collars.
6. Slide the snorkel into the vent pipes and secure to the wall.
warning
7. Level the soil so as to maintain a 4" clearance below snorkel. Figure 26
• Do not back fill around snorkel.
• A clearance of at least 4" must be
maintained between the snorkel and
the soil.
If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten
brackets to wall first, then secure to snorkel with self drilling #8 x 1/2 sheet metal screws. It will be necessary to
extend vent pipes out as far as the protruding wall face. Figure 27

1. Determine the route your vertical venting will take. If ceiling
joist, roof rafters or other framing will obstruct the venting
system, consider an offset. Refer to Figure 30 to avoid cutting load bearing members.
For optimal flame appearance, a restrictor disk is necessary
on straight vertical runs of 20' of more.
• Runs may not incorporate elbows.
• The disk is part number 45D0551 and is included in
installation manual packet.
• Drop the disk into a 4" inner collar before installing the
first section of flue or install at the last section before
installing the termination.
• An additional disk may be installed on runs of 35' or
more. Rotate disks perpendicular to each other.
NOTE: Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shows in Figure 13, Page 20.

3. Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before
cutting hole in roof). The 91/2"x91/2" (241 mm x 241 mm) hole must be measured on the horizontal. Actual
length may be larger depending on the pitch of the roof. There must be a 1" minimum clearance from the vent
pipe to combustible materials. (Insulation should be considered a combustible material).
4. Connect a section of pipe and extend up through the hole.
NOTE: If an offset is needed to avoid obstructions, you must support the vent pipe every three (3) feet.
Use wall straps for this purpose. Refer to Figure 28, Page 23. Whenever possible, use 45° elbows instead
of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air.
5. Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the
roof and framing with roofing nails. Be sure roofing material overlaps the top edge of the flashing. There must
be a 1" clearance from the vent pipe to combustible materials.
6. Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements.
NOTE: You must increase vent height for steep roof pitches. Nearby trees, adjoining roof lines, steep
pitched roofs, and other similar factors may cause poor draft or down-drafting in high winds. Increasing
the vent height may solve this problem.
NOTE: If the vent pipe passes through any occupied areas above the first floor, including storage spaces
and closets, you must enclose pipe. You may frame and sheetrock the enclosure with standard construction
material. Make sure to meet the minimum allowable clearances to combustibles. Do not fill any of the
required clearance spaces with insulation. Cathedral

Installing gas piping to fireplace / burner system location
A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.
All electric heaters have hot and arcing or sparking parts inside. Do not store or
use gasoline or other flammable vapors and liquids in the vicinity of this or any
other appliance.
installation items needed
Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator (supplied by installer) •
Piping (check local codes) •
Sealant (resistant to propane/LP gas) • Equipment shutoff valve*
• Test gauge connection* •
Sediment trap (recommended)
• Tee joint
• Pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certified equipment shutoff valve from your dealer.
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do
not reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with
the vent pointing down as shown in Figure 40. Pointing the vent down protects it from freezing rain or sleet.

A manual shutoff valve must be
installed upstream of the appliance.
Union tee and plugged 1/8" NPT
pressure tapping point should be
installed upstream of the appliance.
See Figure 36.
NOTE : The gas line connection may be made using 1/2" rigid tubing or an approved flex connector.
Since some municipalities have additional local codes it is always best to consult your local authorities
and the current edition of the National Fuel Gas Code ANSI.Z223.1, NFPA54. In Canada CSA-B149 (1 or

caution
A listed manual shutoff valve must be installed upstream of the appliance.
Union tee and plugged 1/8" NPT pressure tapping point should be installed
upstream of the appliance. Figure 41
IMPORTANT: Install main gas valve (equipment shutoff valve) in an
accessible location. The main gas valve is for turning on or shutting off
the gas to the fireplace.
Use pipe joint
sealant that is
resistant to liquid
petroleum (LP) gas.
Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess
sealant in pipe could result in clogged burner system valve.
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 41. Locate sediment
trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and burner system.
Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap collects moisture and
contaminants and keeps them from going into the burner system gas controls. If sediment trap/drip leg is not
installed or is installed wrong, burner system may not run properly.

15 to 30 minutes, the flame should be yellow and
slightly taller than the rear log. Figure 59
If the flame is blue and only in the center, turn off
unit and let cool. After unit is cool, remove logs and
check to make sure rock wool is placed correctly.
Replace logs.
NOTE: The type of installation, vent system
configuration, and wind effects may cause the
flame patterns to vary.

cleaning and maintenance
Vent System
The fireplace and venting system should be inspected before initial use and at least annually by a qualified field
service person. Inspect the external vent cap on a regular basis to make sure that no debris is interfering with the
airflow. Inspect entire venting system to ensure proper function.
Glass Door
Thoroughly clean the inside of the glass door after using the fireplace for ten hours. Periodically clean the glass
door as necessary.
When cleaning the glass, remember:
•
Do not remove the glass when hot. Allow glass to cool before removal.
•
NEVER use abrasive materials.
•
Keep children and pets a safe distance away.
•
Never operate the fireplace without the glass door properly secured.
•
Never operate the fireplace if the glass is broken.
•
Replace any glass that is chipped, cracked, or broken. Replacement glass door assemblies MUST be supplied by the fireplace manufacturer ­– No substitute materials may be used.
•
Handle glass door with care to avoid striking or scratching it on hard objects.
To clean glass door, follow “Glass Removal” procedure outlined in the Final Installation section. Film deposit on
the inside of the glass should be cleaned off using a nontoxic, non-corrosive, non-abrasive, mild-cleaning solution.
Simply apply an adequate amount to the glass and wipe off with a damp cloth. After all maintenance has been
completed, re-install glass door.
Logs
Leave logs installed in the fireplace for cleaning. Vacuum surface of the logs with a brush attachment. If logs must
be removed for cleaning, handle carefully by holding gently at each end. Gloves are recommended to prevent
skin irritation from ceramic fibers. If skin becomes irritated, wash gently with soap and water. Vacuum surface of
logs with brush attachment or brush logs with a soft bristle brush (i.e. clean, dry paintbrush). To place logs back
in the fireplace, see “Log Placement” found in the Final Installation section.
NOTE: Do not use fluids to clean ceramic fiber logs.
Rock wool
Replace or add rock wool as required following installation instructions in the Final Installation section of this
manual.

C. Defective or malfunctioning
thermopile
D. Defective valve
A. Check that thermocouple flame impinges on thermocouple.
Clean and/or adjust pilot for maximum flame impingement.
Ensure that the thermocouple connection at the gas valve
is fully inserted and tight.
Disconnect the thermocouple from the valve, place one millivolt lead wire on the tip of the thermocouple and the other
meter lead wire on the thermocouple copper lead. Start the
pilot and hold the valve knob in. If the millivolt reading is
less than 15 mV, replace pilot assembly.
B.If thermocouple is producing more than 15 mV, replace
faulty valve.
A. Check switch and wire for proper connection. Place jumper
wires across terminals of switch. If burner comes on,
replace defective switch.If the switch is OK, repeat the
same procedure on remote control If burner comes on,
replace remote control.
Place jumper wire across wire at gas valves (terminals
marked TH and TP/TH). If burner comes on, wires are
faulty or connections are bad. Replace wire.
B.If pilot flame is not close enough to the thermopile, adjust
pilot flame.
C.Check thermopile wire connections to make sure all are
tight and that the thermopile is fully inserted into pilot
assembly. Check thermopile with a millivolt meter. Connect
leads to TP and TP/TH terminals on the control valve. If
meter reading is below 325 mV, replace pilot assembly.
D.Turn valve knob to “On” and switch to “ON.” Take a reading
at the thermopile leads (TP & TP/TH) on the valve. If the
meter reads greater than 175 mV and the burner does not
light, replace defective valve.
