Connect The Wiring - NuTone 768CHNT Manual De Instrucciones

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 connec-
tor 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.
