Installation And Clearances (Vent-Free Operation Only)
INSTALLATION
WARNING: A qualified service person must in-
stall heater. Follow all local codes.
WARNING: Before installing in a solid fuel burn-
ing 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. A dirty chimney flue may create and
distribute soot within the house. Inspect chimney
flue and firebox 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 unless installed as a
vented appliance (Variable Manually-Controlled
Models Only) (see page 10)
in a recreational vehicle
where curtains, furniture, clothing, or other flam-
mable objects are less than 42 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 (such
as, but not limited to, tobacco smoke, aromatic
candles, cleaning fluids, oil or kerosene lamps, etc)
in the air exist, may discolor walls or cause odors.
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 beneficial, installing heater in rooms without enough venti-
lation air may cause mildew to form from too much moisture. See
Air for Combustion and Ventilation, pages 4 through 6.
NOTICE: State or local codes may only allow opera-
tion of this appliance in a vented configuration. Check
your state or local codes.
NOTICE: This heater is intended for use as supple-
mental heat. Use this heater along with your primary
heating system. Do not install this heater as your
primary heat source. If you have a central heating
system, you may run systems circulating blower
while using heater. This will help circulate the heat
throughout the house. In the event of a power outage,
you can use this heater as your primary heat source.
