Crawl Space Vent
Installation
Keeping air moving in your crawl space can
help to remove moisture and inhibit mold
and mildew growth. The Gable Mount
unit can be mounted as described above,
or a box frame can be built to hold the fan
in position. It is recommended that you
evaluate your crawlspace to determine the
best method.
To Build the Box Frame
Step 1
Depending on the distance your fl oor
joists are separated, you will need to cut
4 braces: two at 14.5" for the side braces,
one at 17.5" for the bottom brace and
one between 17.5"
and 25.5" for the top
brace (Figure 15).
Most fl oor joists are
either 16" on center
or 24" on center.
Measure the distance
before cutting the
top brace to be
sure of the distance
required.
Step 2
Fasten the 4 boards
together with 3"
screws to make a
square box with

Step 4
Mount the fan
inside the frame
by attaching the
brackets with
included mounting
screws. Center the
fan in the frame
making sure that there is at least 4" of
clearance between the fan housing and
the crawlspace vent opening. (Figure 21)
Mounting the Solar Panel
Maintenance Tip: The solar panel is most
effective when clean and free of dust, leaves,
and debris. Normally, rainwater will cleanse
the solar panel and keep it operating at
peak effi ciency. If necessary, simply hose off
the solar panel between rain showers.
Surface mounting on asphalt roofs:
Step 1
Determine the

for mounting the
solar panel. It is
recommended the

facing roof slopes are ideal.
Note: This product comes with 30 feet of

extension wire, as this is suitable for the vast
majority of installations. However, the panel
can be placed up to 60 feet away from the
fan's location without having a meaningful
drop in performance. If the distance exceeds
30 feet, a Wire Extension Kit specifi c to this
product will need to be purchased separately
from your building materials supplier.

to allow the sealant

Step 9
After attaching the mounting base to
the roof deck feed the connecting cable

through the hole in the roof deck. Leave

enough slack under the solar panel
to allow the panel full travel to avoid
pinching the cable or pulling on the cable
connection during adjustment.
Step 10
Adjust the tilt of the panel to maximize
exposure to the sun throughout the day.
The optimal adjustment is to have the
panel 90 degrees to mid-day path of the
sun. If desired, the angle of the panel can
be adjusted as the seasons change to
maximize sunlight captured.
