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.

3.Thread rod onto grille screw in housing, until pan is tight against ceiling.

4. Install bulbs. (see "Bulb Replace- ment" chart on next page for proper

bulbs for your model).

5. Place glass shade over mounting rod and align shade onto grille pan. Secure glass shade to grille pan with

finial cap and finial nut as shown.

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