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.). 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.
2. mark and drill a guide hole centered between roof
rafters.
3. From the outside, use the guide hole as a starting point
to lay out the installation:
A. Use a T-square to measure 9
guide hole, then up 12
corner of the layout.
B. Starting from the top-left corner, mark the rectan-
gular cutout (18" W x 20½" H) and remove only the
shingles in this area.
C. mark an 11" diameter hole centered on the guide
hole. Cut this hole through the roof board(s).
D. mark and cut a 1¼" diameter hole through the roof
board(s) where shown.
