Air King exhaust fans designed for installation in fire rated
ceilings are sold and shipped with the components broken
down. For Models AK80, AK90, AK110 and AK130 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 AK80, AK90, AK110 and AK130 housings are
designed to mount between 16” on centre joists using the
supplied mounting rails, or from above by using the key hole
slots on the sides of the housing (ceiling brackets not supplied).
Disconnect the power before beginning this installation.
All wiring and ducting must comply with local and national
Read these instructions fully before beginning this installation.
1. Install mounting rails on the housing and locate the housing
between the joist. Line up the housing on the joist so that the
fan/light housing will be flush with the finished ceiling. Nail or
screw the housing in place securely.
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 AK80, AK90, AK110 and AK130 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 blower housing factory
mounted) into the housing at approximately a 45˚ angle, with
the notched side of the venturi down. As you are installing
the venturi, plug the motor into the receptacle. The notched
side of the venturi should be locked under the lances in the
housing (fig. 1).
3. Once in place secure the venturi with the screw removed
4. Rotate the blade to make sure it spins freely.
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 on two sides of the damper and rails with
slots to accept the grill springs on the other two sides.
2. With the damper in place secure it using the four screws
packaged with the damper.
3. To mount the grill, squeeze the grill springs together and
insert them into the slots provided on the damper rails.
