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).
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.
Figure 8
2. Ensure duct joints and exterior penetrations are sealed with caulk or
other similar material to create an air-tight path to minimize building
heat loss or gain and to reduce the potential for condensation. Place/

MAKE SURE POWER IS SWITCHED OFF AT SERVICE
ALL ELECTRICAL CONNECTIONS MUST BE MADE
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.
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 10). Use
approved methods for all connections.
