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.
