INSTALL THE HOUSING
(continued)
Existing Construction
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 DUCTWORK
NOTE: The duct connector
has a counter-balanced
damper flap. The flap will be
"open" approx. 1" when duct connector is attached to hous-
ing. 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.
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 hous-
ing.
2. Connect 4" round duct to damper/duct connector and ex-
tend 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.
