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
manufacturer.
Before servicing or cleaning the unit, switch power
off at the service panel. To prevent power from
being switched on accidentally when the service
disconnecting means cannot be locked 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 not
damage electrical wiring or other hidden utilities.
Ducted fans must always be vented to the outdoors.
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.

BFQ series bathroom fans come complete with a metal ‘snap-in’
mounting bracket. On the side of this bracket is a drywall gauge
(fig. 1) to allow for fan height adjustment through different ceiling
drywall thickness.
Mounting the
Housing: New
Construction
Select the desired location to
mount the fan.
1. Line up the bracket on the
joist so that the bottom of
the fan will be flush with
the finished ceiling. Nail or
screw the snap-in bracket
in place securely as shown
in fig. 1.
2. On the fan body remove
the wire compartment
cover and select the desired electrical knockout and remove it.
Install an approved 1
1
/2” electrical connector in the knockout.
3. Snap the fan body into the snap-in bracket as shown in fig. 2.
The fan can be ducted either left or right – whichever is most
convenient.
Mounting the Housing: Existing Construction
Select the desired location to mount the fan.
1. Drill a small hole through the ceiling at the chosen location. Stick
the end of a coat hanger through the hole into the attic to help
locate the spot in the attic.
2. Check the chosen area
from above to make sure
that the wiring and ducting
can be installed and that
the installation will not
interfere with any existing
wiring. Remove the
electrical compartment
cover and remove the
desired electrical knockout.
Install an approved 1
1
/2”
electrical connector in the
knockout.
3. From above, position the
housing next to the joist
and use the housing as a
template to mark the required cut out in the ceiling.
4. After making the cut out for the fan, you will have to install the
snap-in bracket from below. Line the bracket up so that the fan will
be flush with the finished ceiling. Nail or screw the bracket to the
joist securely as shown in fig. 1.
5. Snap the fan body into the snap-in bracket as shown in fig. 2. The
fan can be ducted either left or right – whichever is most
convenient.
Ducting
When installing the ducting always try to ensure that there is a
downward slope away from the fan to ensure that there is no
condensation run back. It is recommended that you use insulated
ducting.
NOTE: All ducting must
comply with local building
codes.
1. Connect the correct ducting
to the fan as shown in fig.
3. (BFQ model fans come
complete from the factory
with a 4” duct collar.)
Secure in place using duct
tape or a screw clamp.
Always duct these fans to
the outside through the
wall or roof cap. To ensure
maximum delivery keep the
length of duct and number
of elbows to a minimum.
Electrical Wiring
CAUTION: Make sure the power is switched off before making this
installation.
NOTE: All wiring must comply with local and national codes. You
must ground this unit.
1. Run wiring from a wall switch (not provided) to the housing
electrical compartment, 1 neutral (white), 1 ground (green or bare
copper wire), and 1 hot (black lead connected to the switch).
Secure the electrical wire 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).
2. Make the connection to the fan’s green ground screw first (use
approved electrical conductors).
3. Connect the white wire from the house to the white wire of the
fan’s receptacle. Connect the one black wire from the fan switch
to the black wire of the fan’s receptacle (use approved electrical
conductors). Replace the fan’s wire compartment cover.
Completing the Installation
1. After you have installed the housing in the ceiling, run ducting
from the unit to the outside and have made all the necessary
electrical connections you can install the fan’s motor plug into the
fan’s receptacle. Rotate the blower wheel by hand to ensure it
revolves freely.
2. To install the grill, squeeze the two ends of each spring fastener
together and insert each into the slots on the venturi. Push the
grill up to the ceiling.
