This insert is a vented product. This insert 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 prop-
erly 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 insert
may not have been installed properly. Get fresh air at once!
Have the insert inspected and serviced by a qualified service
person. Some people are more affected by carbon monox-
ide 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 insert.
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 insert, 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 neighbor’s
phone. Follow the gas supplier’s instructions.

Plan for the installation of your insert. This includes determining the size of fireplace in which
unit is to be installed, length of venting to be used and finishing details, and whether any optional
accessories (i.e. 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:
• 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
8 and 9, Figures 4 and 5.
• 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 Z33.1/
NFPA 54 (current edition), the Uniform Mechanical Code (current edition), and Local Building
Codes for specific installation requirements.

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

 Please review the following carefully.
It is normal for inserts 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.
It is not unusual for your insert to give off some odor the first time it is burned. This is due to the curing
of the paint and any undetected oil from the manufacturing process.
