1. Locate the ventilator at the center of the rear slope of the
roof. Place it as high on the roof as possible. The location
should be free of obstacles (T.V. leads, electrical lines,
etc.) If the ventilator top is level with the roof peak, it can't
be seen from the street. Keep this approximate location
in mind as you work from within the attic.
2. Mark a spot halfway between rafters.
3. Drill a guide hole through the roof at this mark.
4. Cut out the template found on the carton.
5. Push a large nail through the center of the cardboard
template and into the guide hole.
Using the large half of the template, draw a 17½" diameter
circle on the shingles.
