INSTALLATION
WARNING: To reduce the risk of fire, do not store
or use gasoline or other flammable vapors and
liquids in the vicinity 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.
8. For best results, choose a location which allows

possible duct run and the fewest number of
elbows.
9. Position unit between joists and extend
mounting brackets. Position brackets such
that the bottom edge of housing will be flush

slot on all four mounting brackets. (FIG. 6)
10. Remove unit temporarily, and drive nails
partially into joists at all four marked locations.
(FIG. 7)
11. Hang unit from nails and use embossed
measuring guides to check if unit will be flush
with finished ceiling. Drive nails tight. For wide
joist centers: A #8 x 3/8 self-tapping screw can
be used to join extended brackets together and
create a rigid mount. To ensure a noise-free
mount, crimp the bracket channels tightly
around mounting brackets. (FIG. 8)
12. Snap the damper/duct connector onto housing.
Make sure that tabs on the connector lock in
housing slots. (Top of damper/duct connector
