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.

The dimensions shown on Pages 9 and 10, Figures 3 and 4, are minimum
clearances to maintain when installing this heater. Follow these instructions
carefully to ensure safe installation. Failure to follow instructions exactly can
create a fire hazard.
The following factors should be taken into consideration:
• This insert should have sufficient access for its safe operation and maintenance.
• The flow of combustion and ventilation air must not be obstructed.
• Minimum clearances to combustibles, such as mantels, must be maintained. Refer to
Pages 9 and 10, Figures 3 and 4.
• Never obstruct the front opening of the insert.
• Do not install in the vicinity where gasoline or other flammable liquids may be stored.
• These units can be installed in a bedroom. Refer to National Fuel Gas Code ANSI

When the unit is installed into a wood burning fireplace, the minimum distance the mantel
can be placed above the fireplace is governed by local building codes applicable to wood
burning fireplaces. Consult local authorities having jurisdiction for these clearances. The
underside of the mantel will become warm. Use only finishes which are heat resistant and
do not discolor.

• The insert must be placed within a code-conforming masonry fireplace or a tested and
listed zero-clearance (UL-17, solid fuel) fireplace. Repair any fireplace damage prior to
installation.
• Because the insert uses a circulation blower, clean the fireplace, smoke shelf and chim-
ney before installing.
• This heater may be placed in a bedroom. Please be aware of the large amount of heat
this appliance produces when determining a location.
