GENERAL INFORMATION 1. For a power attic ventilator to effectively cool, it should provide at least ten air changes per hour. To determine the proper CFM rating for a fan that will provide that number of air changes, the total square footage of an attic must be multiplied by .7. This will give the CFM rating for the fan needed for an attic. Example: for a home with 1500 square feet of attic space, the calculation would be as follows: 1500 x .7 = 1050.

. Cut a rectangular hole centered around the drilled hole 14 1/2” wide by 17” long. Be sure the 17” side is parallel to the rafters. 4. With mounting plate parallel to ridgeline of roof, slide the upper outer flange of the plate under the row of shingles just above the cutout so that the housing portion of unit can be centered in the cutout opening. See Fig. 3. 5.

MINIMUM ATTIC INTAKE AREA REQUIRED Sufficient intake area must be provided in the attic to assure that the fan will not be overloaded and that it will deliver its rated CFM. This can be accomplished with some type of attic venting such as gable louvers or under-eave vents. The table below shows the minimum intake area needed for each fan installed.
