Instructions / Assembly
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.
Existing Construction
2. In attic, position mounting brackets against joist. Trace outline 
of housing on ceiling material.
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.
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.

CONNECT THE WIRING
1.  Wire unit following diagram above. Run electrical cable as direct 
as possible to unit. Do not allow cable to touch sides or top of 
unit after installation is complete. 
INSTALL THE DUCTWORK
FLUSH
NOTE: The duct connector has a 
counter-balanced damper flap. The 
flap will be “open” approx. 1” when 
duct connector is attached to hous-
ing. This design permits insulation 
to be in direct contact with fan/
light housing per UL (Underwrit-
ers Laboratories) standards. The 
slightest backdraft, however, will 
close the damper 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 connector. 
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.
