WARNING: Never install the
heater
• in a bedroom or bathroom
unless installed as a vented
appliance (Variable Manually-
Controlled Models Only) (see

• in a recreational vehicle
• where curtains, furniture,
clothing or other ammable
objects are less than 42" from
front, top or sides of heater
• in high trafc 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 u-
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 benecial, 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.

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.
