2. Position the damper inside of the damper frame and secure
the damper by bending the two tabs up and around the lip of
the damper (Figure 8).
NOTE: The damper will only fit into the damper frame one way.
If the damper is not fitting flush against the damper frame, turn
the damper 90°.
3. Line up the slots in the damper frame with the lances on the
housing and install the damper frame and damper up into the
housing. The damper will fit inside of the housing while the
damper frame will fit outside of the housing. Secure in place
by inserting the included #8 screws through the slots of the
damper frame and into the lances of the housing (Figure 9).
4. If there are any gaps between the drywall and the ceiling
damper frame, seal them with caulk carrying the appropriate
UL rating (Figure 10).
SECTION 5
Wiring
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE
MADE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES,
OR NATIONAL ELECTRICAL CODE. IF YOU ARE UNFAMILIAR
WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE
THE SERVICES OF A QUALIFIED ELECTRICIAN.
1. Run wiring from an approved wall switch carrying the
appropriate rating. One neutral (white), one ground (green or
bare copper), and one hot (black lead connected to the switch).
Secure the electrical wires to the housing with an approved
electrical connector. Make sure you leave enough wiring in
the box to make the connection to the fan’s receptacle.
2. From where you have access to inside the fan’s junction box,
connect the white wire from the house to the white wire from
the fan’s receptacle. Connect the black wire from the wall
switch to the black wire from the fan’s receptacle. Connect the
ground wire from the house to the green wire from the fan’s
receptacle (Figure 6). Use approved methods for all connections.
SECTION 6
Completing the Installation
1. Reinstall the fan’s venturi by holding it at approximately a 45
degree angle, hook the two tabs on the venturi into the slots
on the housing and secure in place by tightening the venturi
screw. Rotate the blower wheel by hand to ensure it spins
freely. Now plug the fan motor into the receptacle (Figure 7).
