WARNING: Never install the
heater
• in a bedroom or bathroom
unless installed as a vented
appliance (Variable Manually-
Controlled Models Only) (see
page 12)
• in a recreational vehicle
• where curtains, furniture,
clothing or other flammable
objects are less than 42" from
front, top or sides of heater
• in high traffic areas
• in windy or drafty areas
CAUTION: This heater cre-
ates warm air currents. These
currents move heat to wall sur-
faces 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 flu-
ids, 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 ventilation
air may cause mildew to form from too much
moisture. See Air for Combustion and Ventila-
tion, page 6.
CHECK GAS TYPE
Use the correct gas type (natural or propane/
LP) for your unit. If your gas supply is not cor-
rect, do not install heater. Call dealer where
you bought heater for proper type heater.
WARNING: This appliance is
equipped for either natural gas
or propane/LP gas but not both.
Gas type is indicated on the rat-
ing plate. Field conversion is not
