INSTALLATION IN EXISTING
CONSTRUCTION
Refer to Figure 5.
NOTE: In existing construction, hanger bar and mounting
brackets are not used.
1. Determine desired location of heater. Area above heater
must be free of plumbing and electrical wiring. There must
be enough clearance above ceiling for heater housing and
installation of duct and wiring.
2. Drill a small hole up through ceiling and insert a wire or nail to
help in locating from above.
3. Locate hole from above. Center heater housing between joists
and use the bottom flange of housing as a template to mark
cutout. Cut out hole in ceiling.
4. Refer to Figure 3. Secure short pieces of 1" x 3" lumber
(¾" nominal) to joists on either side of opening. Leave
approximately ½" between top of ceiling so that flange of
heater housing can slide under spacers. If joist spacing is
greater than 16" O.C., cut spacers of 2" x 4" lumber to fit
between housing and joists.
5. Place heater over opening and between spacers. From below,
align housing so
flange is flush with
finished ceiling.
Secure to spacers
with nails or wood
screws though
keyhole slots. NOTE:
If necessary, housing
can be installed from
below by removing
vent blower, vent
housing, and outlet
box.
6. Install 4" duct and
refer to previous
section of these
instructions for Wiring
and Completing
Installation.
