PREPARE LOCATION AND INSTALL BLOWER
FLAT OR LOW SLOPE ROOF MOUNT
1. For flat roofs having a pitch less than 1-1/2” of rise per 12”
length, mount the blower on a roof curb as shown in Figure
#1.
2. Position the blower so that discharge-end of the blower slopes
downward and away from prevailing winds.
3. Use flashing and roofing mastic to prevent leaks between
the roof, the curb, and the blower.
4. Cut holes for ducting and electrical wiring as shown below.
TYPICAL ROOF MOUNT
1. Position the blower so that discharge-end of the blower slopes
downward and away from prevailing winds.
2. Center the blower duct opening between roof rafters.
3. Remove shingles from the 20” x 20” area and cut openings
for ducting and electrical wiring as shown in Figure #2.
4. Apply a quality grade of roof mastic between the bottom of the
remote blower and the roof.
WARNING: Failure to properly
seal between the remote blower and the roof surface may
result in leaks, resulting in damages to roofing and ceiling
material.
5. For proper drainage, shingles must fully cover the blower’s
rear flashing flange and not less than 20” of the side flanges
as shown in Figure #3. The flashing on the discharge-end of
the blower must rest on top of the roof shingles.
TYPICAL ROOF MOUNT, CONTINUED
6. Fasten the blower to the roof using the mounting screws
provided.
7. Apply roof mastic between the shingles, the remote blower,
and any exposed screw heads.
WALL MOUNT WITH LAP SIDING
1. Remove siding from the 24” x 28” area as shown in Figure
#4.
CAUTION: Do not cut through the wooden sheathing
behind the siding.
2. Use furring strips to frame in around the siding. For best
appearance, the thickness of the strips should be equal to
or greater than the thickness of the siding.
3. Anchor the frame securely to the sheathing with glue and
wood screws. Caulk all joints to prevent water leakage.
4. Cut openings for ducting and electrical connector as shown
above.
5. Apply caulk around the front face of the furring strips.
6. Fasten the blower to the frame using the screws provided.
