INSTALLATION INSTRUCTIONS

CAUTION: MAKE SURE POWER IS SWITCHED OFF AT

SERVICE PANEL BEFORE STARTING INSTALLATION.

SECTION 1

Preparing the Exhaust Fan

1. Unpack fan from the carton and conﬁrm that all pieces are present. In addition to the

exhaust fan you should have:

1 - Grill 1 - Hardware Bag

1 - Damper Assembly (attached) 1 - Electrical Connector

1 - Mounting Bracket 3 - Wire Nuts

1 - Instruction/Safety Sheet

2. Remove the wire compartment cover and store in the carton until needed so it does not

get damaged or lost (Figure 1).

3. Choose the location for your fan. To ensure the best

air and sound performance, it is recommended that

the length of ducting and the number of elbows be

kept to a minimum, the radius of each elbow be as

large as possible for the installation, and that insulated

hard ducting be used. Larger duct sizes will reduce

noise and airﬂow restrictions.

4. Select the most convenient electrical

knockout and remove using a straight-

blade screw driver (Figure 2).

5. No additional vibration deadening materials are

needed for this fan.

New Construction - BFQW Models (Oval Duct)

1. Using the gauge on the bracket, line up the bracket on the side of a wall stud such that

the bottom of the fan will be ﬂush with the ﬁnished wall. The bracket should sit one

drywall thickness forward on the stud (Figure 5).

NOTE: For proper damper operation, the duct

adaptor must be facing up towards the ceiling.

NOTE: ½” minimum thickness drywall must be used for

wall mount applications.

2. Nail or screw the bracket in place securely.

3. Snap the fan body into the bracket, making

sure the duct collar is pointing upwards

towards the ceiling (Figure 6).

SECTION 3

Existing Construction - BFQ Models

1. Position housing against the joist

or stud and trace an outline of

the housing onto the ceiling/wall

material. Set housing aside and cut

opening, being careful not to cut

or damage any electrical or other

hidden utilities (Figure 7).

2. Line up the bracket on the joist so

the bottom of the fan will be ﬂush

with the ﬁnished ceiling. Nail or

screw the snap-in bracket in place

securely (Figure 3).

3. Snap the fan body into the bracket The fan can be snapped into position (Figure 4).

with the duct collar facing to the left or the right depending which is most convenient.

Existing Construction - BFQW Models (Oval Duct)

1. Remove a section of the wall material large enough for you to ﬁt the fan housing into as

well as gain access to the top plate, and have enough space to connect the ducting. This

will typically be across two studs and approximately 24" starting at the top of the wall.

2. Follow the instructions in - to Section 2 New Constructions - BFQW Models (Oval Duct)

complete the installation.

NOTE: Wall installation into existing construction will require you to patch the wall material

around the unit.
