IMPORTANT SAFETY INFORMATION
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 head-
aches, 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 quali-
fied 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 indi-
cated 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 neighborʼs
phone. Follow the gas supplierʼs instructions.
Continued on page 4
• 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.

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.
Never connect unit to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
WARNING

We suggest that our gas hearth
products be installed and
serviced by professionals who
are certified in the U.S. by the

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 inspec-
tions.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows. Minimum clearances to combustibles must be maintained.
• This fireplace may be installed along a wall, across a corner, or use an exterior chase. See Figure 5 for suggested loca-
tions.
• 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
not 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
