PREPARE THE FAN / LIGHT

FLUSH
NOTE: The duct connector has a counter-balanced damper flap.
The flap will be "open" approx. 1" when duct connector is attached
to housing. This design permits insulation to be in direct contact
with fan/light housing per UL (Underwriters Laboratories) stan-
dards. The slightest backdraft, however, will close the damper
flap, preventing air from entering unit or finished space.

Allows fan circuit to be turned OFF when desired.
3. Hang housing from
nails. Use measur-
ing guides on cor-
ners of housing to
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 create a rigid mount. To ensure a noise-free mount, crimp
the bracket channels tightly around mounting brackets.
4. 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.
5. 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.
