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.
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).
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
(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.
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
Section 2
-
New Constructions - BFQW Models (Oval Duct)
to
complete the installation.
NOTE:
Wall installation into existing construction will require you to patch the wall material
around the unit.
SECTION 4
Ducting
NOTE: 4" OR LARGER RIGID DUCT IS RECOMMENDED FOR BEST PERFORMANCE.
CAUTION:
ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL
BUILDING CODES.
1.
Connect the ducting to the fan’s duct
collar
(Figure 8).
Secure in place
using tape or screw clamp. Always
duct the fan to the outside through a
wall or roof cap. It is recommended
that low restriction termination
fittings be used.
NOTE:
For oval duct connection, squeeze
standard 4" round rigid ducting to form
an oval shape then follow instructions in
Step 1
.
