CAUTION: If you install the
heater in a home garage
• heater pilot and burner must be at
least 18" (45.7 cm) above floor
• locate heater where moving
vehicle will not hit it
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 Ventilation,
page 5. If high humid-
ity is experienced, a dehumidifier may be used to
help lower the water vapor content in the air.
For convenience and efficiency, install heater
• where there is easy access for operation,
inspection and service
• in coldest part of room
To use fan, locate heater near an electrical
outlet.
