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 DUCTWORK

BJ0003
N O T E : The duct connector
has a counter-balanced damper
fl ap. The fl ap 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 fl ap, preventing air from entering
unit or fi nished 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 fl ush 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.
