injury to persons observe the following:
Do not use this fan with any solid-state speed
control device.
Use this unit only in the manner intended by the

securely, fasten a prominent warning device, such
as a tag to the service panel.
Installation work and electrical wiring must be done
by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated
construction.
When cutting or drilling into wall or ceiling, do

Do not install this fan in a ceiling thermally
insulated to a value greater than R-40
• WARNING: Do not use in kitchens.
• WARNING: Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent back drafting.
Follow the heating equipment manufacturer' s
guidelines and safety standards such as those
published by National Fire Protection Association
(NFPA), and the American Society for Heating,
Refrigeration and Air Conditioning Engineers
(ASHRAE), and local code authorities.

Air King exhaust fans designed for installation in fire rated
ceilings are sold and shipped with the components broken
down. For Models BF90 and BF120 the components are
shipped in 4 pack housings, 4 pack fire dampers, and 4 pack
motor/blade/grills (MBG's). It is best to complete the installation
of the housing during the rough-in stage of construction.
Housing Installation, Electrical
Wiring, and Ducting
This housing will require at least 10" of clearance above the
ceiling. Check the area from above and plan the ducting and
wiring routes. A standard wall switch carrying the appropriate
electrical rating can be used to control the on/off operation of
the fan. The BF90 and BF120 housings are designed to mount
between 16" on centre joists using the supplied mounting rails.
Disconnect the power before beginning this installation.
All wiring and ducting must comply with local and national
codes.
Read these instructions fully before beginning this installation.

INSTALLATION
INSTRUCTIONS
1. Install the mounting rails on the housing and locate the
housing between the joists. When the housing is flush with
the ceiling, the damper retaining flanges will extend below
the ceiling (fig. 1). Secure the housing in place using screws
or nails.
2. Remove one of the electrical knockouts and connect an
approved electrical connector to the housing.
3. Run wiring, one neutral (white), one hot (from switch), and
green or bare ground wire to the fan. Make the connections
to the fan' s receptacle and connect the ground wire to the
green ground screw in the fan housing.
4. Once the electrical connections are made, connect the
ducting. Models BF90 and BF120 come complete from the
factory with a 4" duct adapter. Ducted fans must always be
vented to the outdoors.
Motor, Blade, and Venturi Installation
Once the housing is mounted and wired and ducting is run,
you may install the motor, blade and venturi into the housing.
Leave the grills in the MBG carton until needed so they do
not get damaged.
1. Remove the venturi mounting screw from the housing.
2. Insert the venturi (with motor and blade factory mounted)
into the housing, lining up the 2 tabs on the venturi with the
2 slots on the housing. Insert the venturi into the housing at
approximately a 45˚ angle, with the tabs down.
3. Once in place secure the venturi with the screw removed
earlier.
4. Rotate the blade to make sure it spins freely, then plug the
motor into the receptacle.
Fire Damper and Grill Installation
After the venturi is mounted and the motor is plugged into the
receptacle, you can install the fire damper.
1. Push the damper up into the housing. There are rails for
mounting screws and the grill springs on two sides of the
damper. These will line up with the rails which are on the
housing.
2. Once the damper is in place, bend the 'damper retaining
flanges' (fig. 1). They will bend easily by hand, but you can
use pliers if desired.
H u
3. With the damper in place secure it using the four screws
packaged with the damper.
4. To mount the grill, squeeze the grill springs together and
insert them into the slots provided on the damper rails.
