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, inspec-
tion and service
• in coldest part of room
An optional fan kit is available from your dealer.
See Accessories, page 26. If planning to use fan,
locate heater near an electrical outlet.

WARNING: Maintain the
minimum clearances shown
in Figure 4. If you can, provide
greater clearances from floor,
ceiling and joining wall.
A wall mounting bracket is included with this
heater. An Optional Base Kit (GA4550) may be
purchased to allow the unit to be installed away
from a wall (see Accessories, page 26). Determine
which method is best for your application.
WARNING: Never install the
heater
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,
clothing or other flammable
objects are less than 36 inches
(91.5 cm) from the front, top or
sides of the heater
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
CAUTION: If you install the
heater in a home garage
• heater pilot and burner must
be at least 18 inches (45.7 cm)
above floor
• locate heater where moving
vehicle will not hit it
CAUTION: This heater creates
warm air currents. These currents
move heat to wall surfaces next
to heater. Installing heater next
to vinyl or cloth wall coverings
or operating heater where impu-
rities (such as, but not limited to,
tobacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls or cause odors.
