Determine your mounting
application
One of the great features about the
VentSure Solar Attic Exhaust Fan (Gable
Mount) is the many mounting options.
Gable Vent
If you have a gable
and prefer to avoid
cutting into your
roofi ng materials, use
the gable vent for
mounting the fan.
Static or Turbine Vent
Rather than
removing the static
or turbine vent,
simply use the same
opening.
Static/Turbine Vents
Crawlspace Vent
If your crawlspace
has too much
moisture, increase
the airfl ow and
reduce moisture by
installing near a vent
opening.
Before You Begin
Loosen (but do not
remove) the 8 nuts
(Figure 1) on the 4
mounting brackets
(Figure 2) so they
can slide freely. And
remember: Always
note the orientation
of the fan's air fl ow

mounting
relative to the vent
brackets
opening.
Gable Vent Installation
Important tip for both gable fan installation
methods: To maximize effi ciency of the fan,
seal off the gable vent area around the fan
to avoid recirculating outside air around the
fan and back outside.
For installation in a gable vent you typically
have two options:
Option 1
Vent is located
between standard
16" on center
framing
Step 1
Position the fan over
the louvers and
slide the mounting
brackets into
position against the
framing studs. (Figure 3)
Step 2
Mark the position
of the holes in the
brackets and pre-drill
if necessary. (Figure
4)
Step 3
Use included
mounting screws to
fasten the brackets
to the framing
Gable Vent
studs. There are 8
attachment locations, with two on each
bracket. (Figure 5)
Step 4
Once brackets have
been fastened, slide
the fan assembly into
position, pressing
it fi rmly against the
vent louvers and
tighten the 8 nuts.
(Figure 6)
Option 2
Crawlspace Vent
Vent area requires
additional mounting
braces to support
the fan
Step 1
Measure the distance
between the 2
Loosen
Figure 1 framing members
that the braces will
attach to. (Figure 7)
Step 2
Cut two 2x4 braces
Figure 2
to the required
length. (Figure 8)
Step 3
Locate the two
braces between
14.25" and 15" apart
and centered over
the vent opening and
then fasten to the
framing members
Framing Studs with 3" screws (not
supplied). (Figure 9)
Step 4
16" on center
Then mount the
Option 1
fan as described in
Option 1. (Figure 10)
Figure 3
Static or Turbine Vent
Installation
The Gable Mount
unit can be used to
push hot air out of
Figure 4
your attic through an
existing roof vent.
Important Tip: Seal off other static vents to
avoid turning them into intake vents once
the powered fan is installed and running.
Figure 5
Step 1
Determine the
location of the vent
to be used and
measure the distance
between the two
rafters. (Figure 11)
Step 2
Cut two 2x4 braces to the required length.
Figure 6
Step 3
Locate the two
braces between
14.25" and 15" apart
and centered over
the vent opening
then fasten to the
rafters with 3"
galvanized deck screws (not supplied).
Option 2
(Figure 12)
Step 4
Position the fan
assembly between
the two braces
and slide the fan
Figure 7
assembly towards
the vent opening.
(Figure 13)
Step 5
Fasten the brackets
to the two braces
Figure 8
with included
mounting screws
(Figure 13) and
tighten the 8 nuts.
(Figure 14)
Note: When the rafter is larger than
Figure 9
a 2"x4", (e.g. 2"x6") locate the braces
between the rafters to ensure fan can be
positioned against the vent.
