LOCATION

LOCATION
ROOF INSTALLATIONS
1. Locate the ventilator 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 ventilator
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.
Figure 1
WALL INSTALLATIONS
1. Choose a position on the outside wall. Make sure
that no wall studs, pipes or wires run through the
opening area.
Figure 3
From inside the attic space:
2. Drill a PILOT HOLE up through the roof, 8½"
from the inside edge of a ROOF RAFTER.
From outside - on the roof:
3. Measure and mark the 20¾" x 20½" rectangle.
Cut and remove only the shingles inside this
rectangle.
4. Measure and mark the 11" DIAMETER HOLE
and the 1¼" DIAMETER HOLE. Cut these holes
all the way through the roof.
Figure 2
5. For flat roof installations, build a curb that will mount
the ventilator at a minimum pitch of 2/12. See
Figure 2. Discharge end of the ventilator should
be pointed away from prevailing winds.
From inside the wall:
2. Drill a PILOT HOLE through the wall, 8½" from
the inside edge of a WALL STUD.
From outside - on the wall:
3. Measure and mark the 25" x 29½" rectangle.
Cut and remove only the siding inside this
rectangle.
4. Measure and mark the 11" DIAMETER HOLE
and the 1¼" DIAMETER HOLE. Cut these holes

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 ventilator housing to fit under them.
2. Center the ventilator 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 ventilator 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 ventilator 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.
