Do you have a question about the Tru-lite Ultra Low-Profile Solar Attic Fan and is the answer not in the manual?
Select a location for the solar vent unit, preferably with southern exposure for maximum sunlight.
Hammer a nail at the center and scribe a 14" or 19" circle onto the roof shingles for the hole.
Use a reciprocating saw to cut the marked diameter for the solar attic fan, avoiding framing members.
Ensure fan is installed between or over roof rafters, not through any framing members.
Cut four-inch slits in shingles and tar paper to allow flashing insertion under the shingles.
Insert saw sideways to cut roofing nails around the flashing footprint to prevent sliding.
Apply two concentric rings of caulking material to the underside of the flashing.
Slide flashing under shingles and secure with screws at 3:00, 6:00, 9:00, and 12:00 positions.
Caulk over exposed screw heads and seal areas where slits were made for weather protection.
