3.
Go to the roof. Using the screw as a reference point, trace out a 14” diameter circle.
4.
Use a reciprocating saw to cut out the traced hole pattern from the roof decking. Remove the cut out decking
material from around the hole as needed.
(See Figure 2.3B)
5.
If you have a shingle roof, insert the reciprocating saw sideways between the shingles and roof decking.
Starting at the 3 o’clock position of the vent hole, begin cutting in a sweeping motion under the shingles,
cutting through any roofing nails or staples. Continue cutting counterclockwise around the vent hole until
reaching the 9 o’clock position. Using a roofing knife, cut a 4 inch horizontal slit in the shingles at the 9 o’clock
and 3 o’clock positions of the hole,
allowing the fan’s flashing to slide underneath the shingles.
6.
Apply weatherproof material to the roof.
(See Figure 2.3C)
7.
Position the fan so that it is centered with the vent hole.
(See Figure 2.3D)
8.
Lifting the fan unit up at an angle, apply weatherproof caulking to the bottom side of the fan unit. This will help
keep the fan in place and will seal nice and tight.
9.
Slide the fan unit underneath the shingles until the fan reaches the top of the hole. Secure the fan flashing to
the roof. Finish caulking around the fan and flashing it into the roof to make a nice seal.
(See Figure 2.3E)
Adjusting the Solar Panel
The fan’s solar panel should be adjusted to maximize exposure to the sun’s path during the day. The optimal
adjustment is to have the panel 90 degrees to the midday path of the sun. You can readjust the panel during
winter or summer seasons if desired.
Adjusting Panel Tilt
This fan has two solar panel adjustments: 15° and 45°. Set the angle properly to capture the most direct sunlight.
Remove the screw on both sides of the panel assembly. Lift the panel and swing the panel braces up to the
desired position and re-attach the screw in the applicable holes.
Adjusting Panel Rotation
The fan has a horizontal rotational adjustment that moves 180°. Simply loosen the 4 wing nuts to loosen the
solar panel and rotate for adjustment. If you need more adjustment than 180°, the assembly can be removed by
removing the 4 wing nuts and repositioning the panel. This gives a full 360° rotation ability.
