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.
. 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 prob-
lems, 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 neighbor’s
phone. Follow the gas supplier’s instructions.

odor the first time it is burned. This is due to the
manufacturing process.

Read this homeowner manual thoroughly and follow all
instructions carefully. Inspect all contents for shipping
damage and immediately inform your dealer if any damage
is found. Do not install any unit with damaged, incomplete,
or substitute parts. Check your packing list to verify that

Firebox framing can be built before or after the appliance
is set in place. Construct firebox framing following Figure 2
for your specific installation requirements. Refer to Figure
2 for firebox dimensions. The framing headers may rest
on the top of the firebox standoffs. Do not bring headers
below top of standoffs.  When planning your framing
and installation, keep in mind that your gas line will come
in on the right side of the box (as you are facing it) and
your electricity will come in on the left side.
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.

If you live in a cold climate, seal all cracks around your appliance, and
wherever cold air could enter the room, with noncombustible material.
It is especially important to insulate the outside chase cavity between
the studs and under the floor on which the appliance rests, if the floor
is above ground level.

Plan for the installation of your appliance. This includes determining where the unit is to
be installed, the vent configuration 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, including permits
and inspections.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows. Minimum clearances to com-
bustibles 
• 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 appliance.
• 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. Refer to National Fuel Gas Code ANSI
Z33.1/NFPA 54 — (current edition), the Uniform Mechanical Code — (current edition),
and Local Building Codes for specific installation requirements.
• These units can be installed in a bathroom.

 Any remote wiring (i.e. remote control, wall switch, and optional fan) must be done prior to
final finishing to avoid costly reconstruction.
Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL fire rating
of Zero) may be used to cover the black painted face of the appliance. It is permissible to bring
combustible wall board to the top and side edges of the black painted face. A 300°F minimum
adhesive may be used to attach facing materials to the black surface. If joints between the finished
wall and the fireplace surround are sealed, a 300°F minimum sealant material (General Electric
RTV103 or equivalent) must be used.
