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.
 Early signs of carbon
monoxide poisoning are similar to the flu with headaches,
dizziness and/or nausea. If you have these signs, the fire-
place 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.
1. This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases unless a certified
kit is used.
2. For propane/LP fireplace, do not place propane/LP
supply tank(s) inside any structure. Locate propane/
LP supply tank(s) outdoors. To prevent performance
problems, do not use propane/LP fuel tank of less than
100 lbs. capacity.
3. If you smell gas
• shut off gas supply.
• do not try to light any appliance.
• do not touch any electrical switch; do not use any
phone in your building .
• immediately call your gas supplier from a neigh-
bor’s phone. Follow the gas supplier’s instruc-
tions.
4. Never install the fireplace
• in a recreational vehicle
• where curtains, furniture, clothing, or other flam-
mable objects are less than 42" from the front, top,
or sides of the fireplace
• in high traffic areas
• in windy or drafty areas
5. This fireplace reaches high temperatures. Keep chil-
dren and adults away from hot surfaces to avoid burns
or clothing ignition. Fireplace will remain hot for a time
after shutdown. Allow surfaces to cool before touch-
ing.
6. Young children should be carefully supervised when
they are in the same room as the appliance. Toddlers,
young children and others may be susceptible to
accidental contact burns. A physical barrier is recom-
mended if there are at risk individuals in the house. To
restrict access to a fireplace or stove, install an adjust-
able safety gate to keep toddlers, young children and
other at risk individuals out of the room and away from
hot surfaces.
7. Do not modify fireplace under any circumstances. Any
parts removed for servicing must be replaced prior to
operating fireplace.
8. Turn fireplace off and let cool before servicing, install-
ing, or repairing. Only a qualified service person should
install, service, or repair the fireplace. Have burner
system inspected annually by a qualified service
person.
9. You must keep control compartments, burners, and
circulating air passages clean. More frequent clean-
ing may be needed due to excessive lint and dust.
Turn off the gas valve and pilot light before cleaning
fireplace.
10. Have venting system inspected annually by a quali-
fied service person. If needed, have venting system
cleaned or repaired. Refer to Cleaning and Mainte-
nance, Page 44.
11. Keep the area around your fireplace clear of combus-
tible materials, gasoline, and other flammable vapor
and liquids. Do not run fireplace where these are used
or stored. Do not place items such as clothing or deco-
rations on or around fireplace.

12. Do not use this fireplace to cook food or burn paper or
other objects.
13. Never place anything on top of fireplace.
14. Do not use any solid fuels (wood, coal, paper, card-
board, etc.) in this fireplace. Use only the gas type

grounded in accordance with local codes or in the
absence of local codes, with the National Electrical
Code, ANSI/NFPA 70, or the Canadian Electrical Code,

16. Do not obstruct the flow of combustion and ventilation
air in any way. Provide adequate clearances around
air openings into the combustion chamber along with
adequate accessibility clearance for servicing and
proper operation.
17. When the appliance is installed directly on carpeting,
tile or other combustible material other than wood
flooring, you must set appliance on a metal or wood
panel or hearth pad extending the full width and depth
of the appliance.

service technician to inspect the appliance and replace
any part of the control system and any gas control
which as been submerged in water.
19. Do not operate fireplace if any log is broken.

Firebox framing can be built before or after the appliance
is set in place. Refer to Figure 2 for fireplace and framing
dimensions. Construct firebox framing following Figure 2
for your specific installation requirements. The framing
headers may rest on the top of the firebox standoffs. Do
not bring headers below top of standoffs.
The firebox may be installed directly on a combustible floor
or raised on a platform of an appropriate height. When
the firebox is installed directly on carpeting, tile, or other
combustible material, other than wood flooring, the firebox
shall be installed on a metal or wood panel extending the
full width and depth of the enclosure.

Plan for the installation of your appliance. This includes
determining where the unit is to be installed, the vent con-
figuration to be used, framing and finishing details, and
whether any optional accessories (i.e. blower, wall switch,
or remote control) are desired. Consult your local building
code agency to ensure compliance with local codes, includ-
ing permits and inspections.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows.

• This fireplace may be installed along a wall, across a
corner, or use an exterior chase. Refer to Figure 3 for
suggested locations.
• Location should be out of high traffic areas and away
from furniture and draperies due to heat from appli-
ance.
• Never obstruct the front opening of the fireplace.
• Do  install in the vicinity where gasoline or other
flammable liquids may be stored.
• Vent pipe routing. Refer to Venting section found in this
manual for allowable venting configurations.
• These units can be installed in a bedroom. See National
Fuel Gas Code ANSI Z233.1/NFPA 54 — (current
edition), the Uniform Mechanical Code — (current edi-
tion), and Local Building Codes for specific installation
requirements.
