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 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.
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 certi-
fied 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. Continuedonpage4

Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following Figure
2 and the chart below for your specific installation requirements. See Figure3 on page 8 for firebox dimensions.
The framing headers may rest on the top of the firebox standoffs. Do not bring headers below top of standoffs.
Pleasenote: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.

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 combustibles  

• This fireplace may be installed along a wall, across a corner, or use an exterior chase. SeeFigure4for sug-
gested 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. See 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 edition), and Local Building Codes for specific installation
requirements.
• These units can be installed in a bathroom.

* When you install your fireplace in (D) room divider or (E) flat on wall corner positions (Y), a minimum of 6"
clearance must be maintained from perpendicular wall and front of fireplace.

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.
