WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer at the address
or telephone number listed in the warranty.
2. Before servicing or cleaning unit, disable the ventilator by covering the solar panel with cardboard or disconnecting the wires
from the motor terminals (note wire locations when disconnecting).
3. Installation work must be done by a qualified person(s) in accordance with all applicable codes and standards, including
fire-rated construction codes and standards.
4. If removing an existing 120 VAC powered attic ventilator, use
only a qualified person(s) to remove any electrical wiring in
accordance with all applicable codes and standards.
5. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment
to prevent backdrafting. Follow the heating equipment manufacturer's guidelines and safety standards such as those published
by the National Fire Protection Association (NFPA), and the
American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
6. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.

CAUTION
1. F o r general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
unit.
3. This unit has an unguarded impeller. Do not use in locations
readily accessible to people or animals.
4. This ventilator operates when the solar panel is exposed to
sun light. To reduce risk of injury while installing, servicing or
cleaning unit, cover the solar panel with cardboard or disconnect the wires from the motor terminals (note wire locations
when disconnecting).
5. The recommended open air inlet for this ventilator is 4.25
square feet. The best location for these air intake vents are
under the eaves with direct access to the attic. Failure to provide these intakes could cause natural-draft gas appliances to
backdraft.
6. Your attic fan installation will create a screened opening into
your attic space. During a heavy rain storm there could be a
light spray of rain into this attic space. This is a normal condition with all attic ventilators and will not cause any damage to
the structure. We recommend that you do not store any valuable articles directly under the fan

INSTALLATION
Note: This ventilator is capable of replacing an existing
120 volt powered attic ventilator. Only a qualified person should remove any electrical wiring in accordance

composite shingle roofing material. This product is also
suitable for installations on tile, slate, metal or membrane
roofs.

3. Separate the ventilator dome from the ventilator base by
removing the four (4) stainless steel 5/16” sheet metal
screws. Lift the ventilator dome off the ventilator base
and proceed to the following steps.
1. Determine the sun’s best exposure location on your roof
barring shade (trees, other buildings etc.) at 4:00pm in
the hottest month of the year. Generally, we recommend
a point located 24” – 36” on center below the roof peak
and centrally along the ridgeline on the south, southwest,
or west side of the home.
2. Prior to installation, we recommend setting up the
ventilator to verify operation. Take the ventilator to a
location exposed to sun. Removing the cardboard
cover from the solar panel should cause the ventilator
to operate. Secure cardboard in place over solar panel
(for safety).

4. Working from the inside of your attic, find the desired
ventilator location and mark a spot halfway between
rafters at a point that is 24” – 36” below the roof ridge.
5. Drill a guide hole through the roof at this mark.
2" MIN.
16-1/8"
19-1/4"
6. Taking into consideration the thickness of your chosen
flashing material, build a 19-1/4” x 16-1/8” (outside
dimensions) curb out of 2” x 4” or 2” x 6” material.

string to scribe a 14” diameter circle on the black paper
or roof decking.
17”
20”
7. Working from the outside of your roof, use the guide
hole as a center point, cut and remove roofing material
in a 20” x 17” minimum area.
9. Drill a large starting hole for the sabre saw just inside of
the line or the 14" circle.
10. Cut out the roof board(s) inside of the line.

11. Center the curb over the hole, ensure the top of curb is
parallel with the roof ridge and toenail in place. Make
sure the curb is securely attached to the roof.
12. Flash with lead, copper or other preferred flashing
materials. Ensure flashing on top two thirds of curb is
installed under adjacent roofing materials.
13. Apply a large bead of silicone on the bottom side of
ventilator base, place over curb and affix with galvanized
nails or screws.
14. Using a good grade of roofing cement material, seal
shingles, flashing and all nail heads. DO NOT seal the
bottom edge of the flashing.
15. Install the ventilator dome to the ventilator base using the
four (4) stainless steel 5/16” sheet metal screws removed
