THE FOLLOWING INSTALLATION ILLUSTRATIONS
SHOW 2 X 6 JOISTS. IF YOU HAVE A TRUSS OR
“I”-JOIST INSTALLATION, MOUNT THE VENTI-
LATOR TO THE ADDITIONAL FRAMING IN THE
SAME MANNER. (Additional framing must be a
2x6 (minimum height).
1. Choose the location for your fan in the ceil-
ing. 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 flush
with finished 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, 900outward.
Lift housing until tabs contact underside of
joist.
Mark the keyhole slot on both mounting
brackets.

1. Choose the location for your fan/light in the ceiling. For
best possible performance, use the shortest possible
duct run and a minimum number of elbows.
2. In attic, position mounting brackets against joist. Trace
outline of housing on ceiling material.
3. Set housing aside and cut ceiling opening slightly larger
than marked.
4. Place housing in opening so that its bottom edge is flush
with finished 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
INSTALL THE DUCTWORK
NOTE: The duct connector has a counter-balanced damper flap.
The flap will be “open” approx. 1” when duct connector is at-
tached to housing. This design permits insulation to be in direct
contactwithfan/lighthousingperUL(UnderwritersLaboratories)
standards.Theslightestbackdraft,however,willclosethedamper
flap, preventing air from entering unit or finished 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 flush with top of housing.
NOTE: Make sure damper flap is in place inside of duct con-
nector. If it is not:

Squeeze top and bottom of connector
to

snap flap 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.
