1. Choose the location for your fan/light in the ceiling. For
best possible performance, use the shortest possible
duct run and a minimum number of elbows.
2. In attic, position mounting brackets against joist. Trace
outline of housing on ceiling material.
3. Set housing aside and cut ceiling opening slightly larger
than marked.
4. Place housing in opening so that its bottom edge is flush
with finished ceiling. Nail to joist through keyhole on both
sides. To ensure a noise-free installation, drive another
nail through the top hole of each mounting bracket.
5. Additional mounting holes are provided for installations
where access from above is inconvenient or not possible.
Nail or screw housing directly to joists or framing.
INSTALL THE HOUSING
INSTALL THE DUCTWORK
NOTE: The duct connector has a counter-balanced damper flap.
The flap will be “open” approx. 1” when duct connector is at-
tached to housing. This design permits insulation to be in direct
contact with fan/light housing per UL (Underwriters Laboratories)
standards. The slightest backdraft, however, will close the damper
flap, preventing air from entering unit or finished space.
1. Snap the damper/duct connector onto housing. Make sure
that tabs on the connector lock into slots in housing. Top of
damper/duct connector should be flush with top of housing.
NOTE: Make sure damper flap is in place inside of duct con-
nector. If it is not:
Squeeze top and bottom of connector
to
snap flap back into place.
2. Connect 4” round duct to damper/duct connector and extend
duct to outside through a roof or wall cap. Check damper to
make sure that it opens freely. Tape all duct connections to
make them secure and air tight.
