Connect The Wiring - NuTone 745BNNT Manual De Instrucciones

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. 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.
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.
