INSTALL THE DUCTWORK
FLUSH
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.
ATTACH THE GRILLE PAN AND
GLASS SHADE
1. Thread a knurled nut onto
the short end of each shade
ring support. Install supports
from top and through holes
in grille pan.
2. Locate the grille pan over
the fan housing and connect
the wiring harness plug into
white receptacle in the fan
housing.
3. Insert rod through center
hole of grille pan. Use washer between collar on rod and
pan. Thread rod onto grille
screw in housing, until pan
is tight against ceiling.
4. Install bulbs. Use 60 Watt
(maximum), candelabra
base bulbs.
5. Install the shade ring onto
two of the supports and
secure each with a knurled
nut.
6. Place glass shade into the
shade ring. Install the third
support and secure with a
knurled nut.
7. Restore electrical power and
check operation of the unit.
