LOCATING HEATER
This heater is designed to be mounted on a wall.
WARNING: Maintain the mini-
mum clearances shown in Figure
4. If you can, provide greater clear-
ances from floor, ceiling, and join-
ing wall.
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 ve-
hicle will not hit it
IMPORTANT: Vent-free heaters add mois-
ture 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 Com-
bustion and Ventilation, pages 4 through 6.
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 to-
bacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls.
WARNING: Never install the
heater
• in a 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
For convenience and efficiency, install heater
• where there is easy access for operation,
inspection, and service
• in coldest part of room
