LOCATION
WALL INSTALLATIONS
1. Locate the blower on the rear slope of the roof.
Place it in a location to minimize duct run. The
location should be free of obstacles (T.V. leads,
electrical lines, etc.). Bear in mind, if the blower top
is level with the roof peak, it will not be seen from
the street. Keep this approximate location in mind
as you work from within the attic.

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 housing to fit under them.
2. Center the blower ring in the 11" diameter 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 blower
housing could leak into the house.
4. Using a good grade of roofing cement, seal all of the
shingles around the housing and flashing sheet as
well as the mounting screw heads.
5. Bring electrical wiring through the hole in the wiring
box and secure it according to local codes.
