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, pages 5 through 7.
If high humidity 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.
