ROOF INSTALLATIONS WALL INSTALLATIONS
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.). 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 and drill a guide hole centered
between roof rafters.
