opening so that
its bottom edge is
flush with finished
ceiling. Screw
housing to joist
through holes in
housing as shown.
5. Seal between
ceiling material and
housing to prevent
air leakage.
INSTALL THE DUCTWORK
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) standards. The slightest backdraft, however,
will close the damper flap, preventing air from entering unit
or finished space.
1. 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.
