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. Locate the grille pan over the fan housing and connect the wiring harness plug into white receptacle in the fan housing.

2. Insert rod through center hole of grille pan. Use washer between collar on rod and pan.

3. Thread rod onto grille screw in housing, until pan is tight against ceiling. Do not over-tighten mounting rod.

4. Install bulbs. Use 60-watt (maximum), B10 type, candelabra bulbs.

5. Place washers and glass shade over mounting rod and align shade onto grille pan. Secure glass shade to grille pan with felt washer(s) and finial nut as shown.

6. Restore electrical power and check operation of the unit.
