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.
Caulking or roofing cement must be used to seal the mounting plate to the roof, especially bottom and
side areas of flange not covered by shingles.
6.
With unit in place, nail the top left corner and top right corner of flange to roof decking and rafters with
galvanized roof nails. This is accomplished by nailing directly through the aluminum plate. Nail the bot-
tom of the flange the same way. Check to be sure all shingles are securely and neatly in place over
top portion of flange. See Fig. 3. Caulking nail heads is recommended.
7.
Installation should be water checked by using a garden hose and spraying water directly on top of
unit. Do not spray water directly into vent opening.
