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.). Bear in mind, 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.

will mount the blower at a minimum pitch of
