Continued
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.
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.

CHECK GAS TYPE

Use only the correct gas type (natural or propane/LP) for your unit.
If your gas supply is not correct, do not install heater. Call dealer where
you bought heater for proper type heater.
