INSTALL THE BLOWER
ROOF INSTALLATIONS
1. Remove roofing nails from the upper 2/3
of the shingles around the cutout area
and carefully lift the shingles to allow the
back flashing sheet on the blower hous-
ing to fit under them.
2. Center the blower ring in the 11" diam-
eter hole, making sure that the 1-1/4"
diameter electrical wiring hole aligns with
the hole in the wiring box.
3. Attach the blower to the roof with the six
screws provided. All six holes in the back
panel must be filled, or any moisture that
may get inside the housing could leak
into the house.
4. Using a good grade of roofing cement,
seal all of the shingles around the hous-
ing and flashing sheet as well as the
mounting screw heads.
5. Bring electrical wiring (from hood) through
the hole in the wiring box and secure it
according to local codes.
