INSTALL THE HOUSING
- PLEASE NOTE -
THE FOLLOWING INSTALLATION ILLUSTRATIONS SHOW 2 X 6
JOISTS. IF YOU HAVE A TRUSS OR “I”-JOIST INSTALLATION,
MOUNT THE VENTILATOR TO THE ADDITIONAL FRAMING IN
THE SAME MANNER. (Additional framing must be a 2 x 6
(minimum height).
1. Choose the location for your fan in the ceiling. For best
possible performance, use the shortest possible duct run
and a minimum number of elbows.
2. Position mounting
brackets against joist
so that bottom edge of
housing will be fl ush
with fi nished ceiling.
Additional positioning
feature for 5/8”, 1”,
& 1-1/4” thick ceiling
material:
Holes in corners of
housing are labeled with various ceiling material thicknesses.
Position housing so bottom edge of joist is visible through
a matched set of holes. The housing is now in the proper
position for that ceiling material thickness.
Additional positioning feature for 1/2” thick ceiling
material:
Bend two tabs, on side of housing,
90° outward. Lift housing
until tabs contact underside of joist.
Mark the keyhole slot on both mounting brackets.

3. Set housing aside and
drive nails partially into
joist at the top of both
keyhole marks.
4. Hang housing from nails
and pound nails tight.
To ensure a noise-free
mount, pound another
nail through the top hole
of each mounting tab.
4. Place housing in opening so that its bottom edge
is fl ush with fi nished ceiling. Nail to joist through
keyhole on both sides. To ensure a noise-free
installation, drive another nail through the top hole
of each mounting bracket.
5. Additional mounting holes are provided for
installations where access from above is
inconvenient or not possible. Nail or screw
housing directly to joists or framing.
INSTALL THE HOUSING (cont’d)
INSTALL THE DUCTWORK
NOTE: The duct connector has a counter-balanced
damper fl ap. The fl ap will be “open” approx. 1” when
duct connector is attached to housing. This design
permits insulation to be in direct contact with fan/light
housing per UL (Underwriters Laboratories) standards.
The slightest backdraft, however, will close the damper
fl ap, preventing air from entering unit or fi nished space.
1. Snap the damper/duct connector onto housing.
Make sure that tabs on the connector lock into slots
in housing. Top of damper/duct connector should be
fl ush with top of housing.
NOTE: Make sure damper fl ap is in place inside of duct connector. If it
is not:
Squeeze top and bottom of connector to
snap fl ap back
into place.
2. Connect 4” round duct to damper/duct connector and extend duct to
outside through a roof or wall cap. Check damper to make sure that
it opens freely. Tape all duct connections to make them secure and
air tight.
