Roof Rafter Roof Rafter Wall Stud Wall Stud 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.
