MOUNTING THE FAN
IMPORTANT: If the fan will be mounted on a flat roof, make a curb on which to mount the fan; the fan must be above the level of the roof’s water line.
1.Determine location of fan (center of attic near roof peak). At desired location, drill a hole through the roof (centered between the rafters).
2.Using the drilled hole as a center, make a 141⁄2” diameter circle on the roof. To make a circle, a compass can be made of a scrap piece of wood with two nails placed 71⁄4” apart.
3.Make cutout in roof along the circle that has been made. If the roof is shingled, cut shingles along the circle using the tin snips, knife etc.
4.Place fan over opening in roof. Nail mounting flange to roof. Caulk around mounting flange to help prevent water seepage. If the roof is shingled, slide mounting flange under the surrounding shingles.
