Mounting the Fan
Sizing Requirements
See sizing chart to assure that you select the correct number
of fans for your situation. Some attics have walled off or
chambered areas that will require additional fans to properly
vent the space.
If you have any questions or concerns please feel free to call
our customer service specialists at 866-446-0966.
For crawlspace applications use 1 fan for every
1200 sq. ft. based on a 2.5 ft. height.
Determine your mounting application
One of the great features about the All Purpose Ventilator is the many mounting options.
Gable Vent Static or Turbine Vent Crawlspace Vent
If you have a tile roof and do not want
to cut into the tiles, use the gable vent
for mounting the fan.
Rather than removing the static or
turbine vent, simply use the same
opening.
If your crawlspace has too much moisture,
increase the airflow and reduce moisture
by installing near a vent opening.
Important Tip:
To maximize airflow to the attic close off any unused
static vents. Use tar paper and staples as shown.
Before you begin:
Loosen (but do not remove) the 8 nuts (fig1)
on the 4 mounting brackets (fig 2) so they can slide freely.
And remember: Always note the orientation of the fan’s
air flow relative to the vent opening. 4 mounting brackets

Gable Vent Installation
For installation in a gable vent you typically have 2 options:
OPTION 1
Vent is located between
standard 16” on center
framing members
OPTION 2
Vent area is larger than the
fan and requires mounting
braces to support fan
Option 1 - vent is located between framing members
Step 1.
Position the fan over the louvers and slide the mounting brackets into position against the vent frame. (fig. 3)
Step 2.
Mark the position of the holes in the brackets and pre-drill if necessary. (fig. 4)
Step 3.
Use included screws “G” to fasten the brackets to the vent frame. There are 8 positions two on each bracket. (fig. 5)
Step 4.
Once brackets have been fastened, slide the fan assembly into position, pressing it firmly against the vent
louvers and tighten the 8 nuts. (fig. 6)
fig. 3 fig. 4 fig. 5 fig. 6
Option 2 - vent area requires additional mounting braces
Step 1.
Measure the distance between the 2 framing members that the braces will attach to. (fig. 7)
Step 2.
Cut two 2x4 braces to the required length. (fig. 8)
Step 3.
Locate the two braces between 14.25” and 15” apart and centered over the vent opening then fasten
to the framing members with 3” screws (not supplied). (fig. 9)
Step 4.
Then mount the fan as described in option 1. (fig. 10)

Important tip for gable fan installations:
To maximize efficiency of the fan, seal off the gable vent area around the
fan to avoid recirculating outside air around the fan and back outside.

Crawl Space Vent Installation
Keeping air moving in your crawl space can help to remove moisture and inhibit mold and mildew growth. The
all purpose ventilator 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 floor joist are seperated, 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 (fig. 17). Most floor 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 inner
dimensions 14.5” x 14.5”. (fig. 18 & 19)
To mount in crawlspace
Step 3.
Mount the frame in front of the vent opening by attaching it to the floor joists with 3”
galvanized screws. If the frame assembly and fan mount lower than the bottom of the
vent opening, (fig. 20) mount the frame about 8” to 10” away from the vent to prevent
direct contact with the foundation when the fan is mounted. (fig. 21a)
Secure the frame to the bottom of the floor joists with at least 2 screws on each side
making sure it is centered evenly on both. (fig. 21b)
Step 4.
Mount the fan inside the frame by attaching the brackets with included screws “G”. 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. (fig. 22)

Static or Turbine Vent Installation
The All Purpose Ventilator can be used to push hot air out of your attic
through existing roof vent.
Step 1.
Determine the location of the vent to be used and measure the distance between the two rafters.
(fig. 13)
Step 2.
Cut two 2x4 braces to the required length.
Step 3.
Locate the two braces between14.25” and 15” apart and centered over the vent opening then fasten to the rafters with
3” galvanized deck screws (not supplied). (fig. 14)
Note:When the rafter is greater than 5” wide locate the braces between the rafters to insure fan can be positioned against the vent.
Step 4.
Position the fan assembly between the two braces and slide the fan assembly towards the vent opening. (fig. 15)
Step 5.
Fasten the brackets to the two braces with included screws “G” (fig. 15) and tighten the 8 nuts. (fig. 16)

Surface mounting on composition roofs:
Orient the solar panel to face the sun for the longest possible exposure during the day, (south or southwest facing slopes are the best).
The powder coated panel base can be mounted to just about any surface.
Step 1.
Loosen and remove screw A (both sides) to allow the panel to swing away from the base.
Set the screws aside. (fig. 24)
Step 2.
Before mounting, make sure to pull the wire back through the hole in the center of the base so the base can lay flat on the roof surface
when installed. (fig. 25)
Step 3.
Mount the base using four 3” galvanized screws making sure to seal the screw holes with a roof tile adhesive as shown. Tilt the panel
away from the base while installing the screws. If the panel is to remain flat against the base when installed it is recommended that
you allow the roof tile adhesive to completely dry before contacting with the panel. (fig. 26 & 27)
fig. 24 fig. 25 fig. 26 fig. 27
Surface mounting for S-Tile, Flat Tile or Metal roofs
Step 1.
Determine the location of the contact points by positioning the panel in the desired area. For S-Tile roofs, find a position with as much
surface area coming in contact with the bottom of the panel as possible. The panel must be mounted on at least 2 rows of tile as
shown. (fig. 28 & 29)
Step 2.
Apply enough roof tile adhesive to the underside of the base to firmly secure the panel to the surface. Both surfaces should be dry
and free of any dirt or solvents. (fig. 30)
Step 3.
The panel can be tilted into two positions with the adjustment arm, chose the best angle and reinstall the adjusting screws (screw A). (fig. 31)

Mounting the Solar Panel
Determine the distance between the vent and
the area you will be mounting the solar panel
The Solar panel unit comes with 30 ft. of wire. It is a good idea to measure the distance from the
vent opening and where you’ll be installing the panel to make sure you have enough wire to cover
the span. (fig. 23) fig. 23

Wall mounting:
Brackets are included to mount the panel to a wall if preferred.
First, assemble the braces to the brackets as follows:
Step 1.
Attach the brace to each bracket with the cross brace bolt and nut (E.) (fig. 32)
Step 2.
Attach the brackets to the panel using the 4 bolts (F.) (fig. 33)
Step 3.
Depending on the material your wall is made of, mount the assembly to the wall using appropriate fasteners
(see “Optional Hardware” on page 1 for details).
(fig. 34 and 35)
fig. 32 fig. 33 fig. 34 fig. 35
Connecting the panel to the fan:
Step 1.
Once the panel and fan are mounted, route the wire from the panel to the fan, attaching the wire to the building
appropriately. We suggest using romex mounting clips or coaxial staple for either wood or masonry available at your
local hardware store or home builder supply. (fig. 36)
Step 2.
Typically the wire will route through an opening in the vent or an unused louver. (fig. 37)
Step 3.
Connect the wires to the fan, matching the red wire to the red connector and the black to the black connector on
the motor. (fig. 38)
Step 4.
Include a drip curve if possible when securing to the wall to prevent water running down the wire and into the attic
or crawl space. (fig. 39)

Thermal Switch
The thermal switch allows the fan to run when the temperature
reaches 80 degrees and shuts the fan off when the temperature
dips below 65 degrees.
You can bypass the switch if you’d prefer the motor to run
continuously during the day. To do this, simply disconnect the
black leads from the switch and black terminal (fig. 40a and 40b)
and re-connect the lead from the switch directly to the motor as
shown (fig. 40c and 40d).
