PREPARE THE INSTALLATION
LOCATION
ROOF 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.). 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.
