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.
CAUTION: If you install the
heater in a home garage
• heater pilot and burner must
be at least 18 inches above
floor
• locate heater where moving
vehicle will not hit it
For convenience and efficiency, install heater
• where there is easy access for operation, inspec-
tion, and service
• in coldest part of room
An optional fan kit is available from your dealer.
See Accessories, page 30. If planning to use fan,
locate heater near an electrical outlet.
