INSTALLATION
WARNING: To reduce the risk of fire, do not store or use
gasoline or other flammable vapors and liquids in the vicin-
ity of the heater.
CAUTION: High temperature, risk of fire, keep electrical cords,
drapery, furnishings, and other combustibles at least 3 feet
(0.9 m) from the front of the heater and away from the side
and rear.
For best results, choose a
location which allows fan to
be vented outside with the
shortest possible duct run
and the fewest number of
elbows.
1. Position unit between
joists and extend mount-
ing brackets. Position
brackets such that the
bottom edge of housing will be flush with finished ceiling.
Mark the top of keyhole slot on all four mounting brackets.
2. Remove unit tem-
porarily, and pound
nails partially into
joists at all four
marked locations.
3. Hang unit from nails and
check if unit will be flush with
finished ceiling. Pound nails
tight. For wide joist centers:
A #8 x 3/8 self-tapping screw
can be used to join extended
brackets together and cre-
ate a rigid mount. To ensure
a noise-free mount, crimp
the bracket channels tightly
around mounting brackets.
