Installation Pointers
When determining location of the unit, try to place the solar attic fan on the south side of the roof, also consider
potential problems such as objects shading the unit during certain times of the day. The unit should also be
centered on the roof and the center of the unit should be about 2 feet down from the roof ridge.
Step 1
Choose location for solar vent unit, south exposure is best. If a southern exposure is not feasible for your installation, the fan can be installed on any
other exposure and the solar panel adjusted to capture maximum sunlight.
Step 2
Hammer a nail at the center of the location chosen between rafters for the
solar attic fan unit. The center of the unit should be about 2 feet down
from the ridge. Attach a string to the nail. Measure 9.5” of string and attach
a marking pen to the string, see diagram. Scribe a 19” circle onto the roof
shingles or use the template created earlier.

Step 3
With a reciprocating saw, cut the diameter of the hole.
IMPORTANT: The solar attic fan must be installed between the roof
rafters or over a roof rafter. DO NOT CUT THROUGH ANY FRAMING
MEMBER.
Step 4
Roof rafters are generally 16” or 24” on center. On 16” on center
construction, the installer can either cut a 14” hole between the rafters or
cut a 19” hole with the roof rafter running through the cut hole - do not
cut the rafter (see diagram). On 24” on center construction, center the fan
between the rafters. NEVER CUT THROUGH ANY ROOF RAFTERS. LEAVE
ALL FRAMING MEMBERS IN PLACE. Only remove roof sheathing.
Step 5
With a razor knife, cut a four inch slit through the shingles and tar paper
at the three and nine o’clock position of the flashing. This allows for the
foot print of the flashing to be inserted under the shingles.
NOTE: If a 14” hole was cut instead of a 19” hole in Step 3,
additional shingles may also need to be removed on the
high side towards the ridge to allow the flashing to slide
over the hole (see inset Illustration).

Step 6
Insert the reciprocating saw blade sideways at the three o’clock position
and commence cutting the roofing nails up and around to the nine o’clock
position. This process removes the nails that will prevent the
flashing foot print from sliding up underneath the shingles.
Step 7
Caulk underside of flashing with the provided caulking material. Two
concentric rings of caulking material is sufficient.
NOTE: Installation on tile roofs will require the use of a skirt.
Step 8
Taking care not to smear caulk on the exposed shingles, slide flashing
under tar paper and shingles and force flashing up until the shingles come
in contact with the raised portion of the flashing. The bottom side of the
flashing will be on top of the shingles. Secure flashing with four Phillips
head screws at the 3:00, 6:00, 9:00 and 12:00 positions. The 3:00 and
9:00 positions screws should go under the shingles. The 6:00 and 12:00
position screws should go on top of the shingles.
Step 9
At the 6:00 and 12:00 positions, caulk over the screw head, since it will be
exposed to the weather. Use remaining caulk to seal the areas where the
4” slits were made and around the area where the shingles meet with the
raised area of the flashing.
Step 10
Loosen, but do not remove, the screw on the clip/screw assembly located
on each side of the solar panel bracket. Adjust the solar panel to the
position it will collect the most sunlight throughout the day. Tighten screws
at the desired position.
