INSTALLING
NOTICE
A qualified service person must install heater. Follow all local codes.
WARNING
Before installing in a solid fuel burning fireplace, the chimney flue
and firebox must be cleaned of soot, creosote, ashes and loose paint
by a qualified chimney cleaner. Creosote will ignite if highly heated.
Inspect chimney flue for damage. If damaged, operate heater with
flue damper closed.
WARNING
Seal any fresh air vents or ash clean-out doors located on floor or wall
of fireplace. If not, drafting may cause pilot outage or sooting. Use a
heat-resistant sealant. Do not seal chimney flue damper.
WARNING
Never install the heater
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other flammable objects are
less than 36 inches from the front, top, or sides of the heater
• in high traffic areas
• in windy or drafty areas
CAUTION
This heater creates warm air currents. These currents move heat
to wall surfaces next to heater. Installing heater next to vinyl or
cloth wall coverings or operating heater where impurities in the air
(such as tobacco smoke) exist, may discolor walls.
CHECK GAS TYPE
Use only natural gas. If your gas supply is not natural gas, do not install heater.
Call dealer where you bought heater for proper type heater.
IMPORTANT:
Vent-free heaters add moisture to the air. Although this is benefi-
cial, installing heater in rooms without enough ventilation air may cause mildew to
form from too much moisture. See Air for Combustion and Ventilation, pages 5
through 7.
NOTICE
State or local codes may only allow operation of this appliance in a
vented configuration. Check your state or local codes.
WARNING
Make sure the remote selector switch is in the OFF position before
installing heater.
