WALL INSTALLATION
EXTERIOR-POWER VENTILATOR
EXTERIOR POWER VENTILATOR KIT
1. Choose a position on the outside wall. Min. 24” (61.0cm)
from ground may vary depending on local codes or
location. Make sure no wall studs, pipes or wires run
through the opening area
2. Drill a guide hole at the center of the opening area.
3. From the outside, use the guide hole as a starting point.
A. Use a T-square to measure 11 13/16” (30.0 cm) to
the left of the guide hole, then down 14 11/16”
(37.3cm) to locate 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 the wall
located from guide hole.
4. Cut a rectangular hole in the siding only. Do not cut
the sheathing. Nail down all siding edges.
5. Mark an 11” (27.9 cm) diameter circle centered on the
guide hole and mark the center of the 1 1/4” (3.2 cm)
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 hold aligns with the hole in the wiring box.
9. 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.
10. Using a good grade of roofing cement, seal all the mounting
screws.
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 wiring being used. Connect white to white,
black to black, and green or bare wire to green.
13. Replace wiring box cover and screws. Do not pinch wiring
under the 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.
