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 - Damper Assembly (attached)
1 - Mounting Bracket
1 - Hardware Bag
1 - Electrical Connector
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.
SECTION 2
New Construction - BFQ Models
1. Using the gauge on the mounting bracket, line up the bracket on the
joist so the bottom of the fan will be flush with the finished ceiling.
Nail or screw the bracket in place securely (Figure 3).
WARNING: PROPER INSTALLATION REQUIRES A MINIMUM
OF 4 SCREWS LOCATED IN HOLES CLOSEST TO DRYWALL.

2. Snap the fan body into the bracket (Figure 4). The fan can be
snapped into position with the duct collar facing to the left or the right
depending which is most convenient.
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).
