LOCATING HEATER
WARNING: Maintain the
minimum clearances shown
in Figure 4. If you can, provide
greater clearances from floor,
ceiling, and joining wall.
You can locate heater on the floor, away from a
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 23). Determine
which method is best for your application.
INSTALLATION
Continued 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
from the front, top, or sides of
the heater
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
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 dehumidi-
fier 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 23. If planning to use fan,
