1. Choose a position on the outside wall. Min. 24” (61.0 cm
from ground may vary depending on local codes or
location. Make sure that no wall studs, pipes or wires
run through the opening area.
2. From inside, mark and drill a guide hole at the center of
the opening area.
3. From the outside, use the guide hoel as a starting point to
lay out the installation.
A. Use a T-square to measure 11
13/16
” (30.0 cm) to the
left of the guide hole, then 14
11/16
” (37.3 cm) tolocate
the top-left corner of the layout.
B. Starting from the top-left corner, mark a 22” (55.9 cm)
by 29
1/2
” (74.9 cm) rectangle on wall located from
guide hole.
4. Cut a rectangular hole in the siding only. Do not cut the
sheathing. Nail down all siding ends.
5. Mark an 11” (27.9 cm) diameter circle centered on the
guide hole and mark the center of the 1
1/4
” diameter
electrical wiring hole.
6. Cut the 11” (27.9 cm) hole in the sheathing and drill the
1
1/4
”(3.2 cm) as marked.
7. Place a large bead of caulk on the back side of the
housing along the outer edge.
8. Center the blower ring in the 11” (27.9 cm) diameter hole,
making sure that the 1
1/4
” (3.2 cm) diameter electrical
wiring hole aligns with the hole in the wiring box.
9. Attach blower to the wall 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.
10. Using a good grade of caulk, seal all around the mounting
screw heads.
11. Bring electrical wiring through the hole in the wiring box
and secure it according to local codes.
12. Make the electrical connections with the proper connector
for the type of wire being used. Connect white to blue,
black to black, and green or bare wire to grounding screw.
13. Replace wiring box cover and screws. Do not pinch wiring
under cover.
14. Check for free movement of the damper before installing
housing cover and screws.
15. Turn on power and check operation of the blower.
16. Top and side flanges of the back plate may be
covered with trim strips. Do not block grill opening
at bottom with trim. It will adversely affect
performance of the blower.

ROOF INSTALLATION

Exterior Power Ventilator
(also see instructions supplied with ventilator kit)
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.
2. Mark a point halfway between rafters.
3. Drill a guide hole through the roof at this point.
4. From the outside, use the guide hole as a starting point to
lay out the installation.
A. Use a T-square to measure 9
13/16
” (24.9 cm) to the left
of the guide hole, then 12
11/16”
(32.2 cm) to locate
the top-left corner of the layout.
B. Starting from the top-left corner, mark the rectangular
cutout and remove only the shingles in this area.
5. Mark an 11” (27.9 cm) diameter hole centered on the
guide hole. Mark the center of the 1
1/4
” (3.2 cm)
diameter electrical wiring hole.
6. Cut out the roof board(s) along the 11” (27.9 cm) diameter
circle and drill a 1
1/4
” hole as marked.
7. For flat roof installations, build a curb that will mount the
blower at a minimum pitch of 2/12. Discharge end of the
blower should be pointed away from prevailing winds.
8. Remove roofing nails from the shingles around the top
and sides of the cutout area only. Carefully lift the
shingles to allow the back flashing sheet on the blower
housing to fit under them.
9. Center the blower ring in the 11” (27.9 cm) diameter hole,
making sure that the 1 ¼” (3.2 cm) diameter electrical
wiring hold aligns with the hole in the wiring box.
10. Attach the blower to the roof with the six screws provided.
It is recommended that the screws be located inside the
blower housing. All six holes in the back panel must be
filled, or any moisture that may get inside the housing
could leak into the house.
11. 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.
12. Bring electrical wiring through the hole in the wiring box
and secure it according to local codes.
13. Make the electrical connections with the proper
connector for the type of wiring being used. Connect
white to white, black to black, and the green or bare wire
to green.
14. Replace wiring box cover and screws. Do not pinch
wiring under the cover.
15. Check for free movement of the damper before installing
housing cover and screws.
16. Turn on power and check operation of the blower.
