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 any questions, contact the manufacturer at the
address or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at
service panel and lock the service disconnecting means to
prevent power from being switched on accidentally. When the
service disconnecting means cannot be locked, securely
fasten a prominent warning device, such as a tag, to the
service panel.
3. Installation work and electrical wiring must be done by a
qualified person(s) in accordance with all applicable codes
and standards, including fire-rated construction codes and
standards.
4. 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 guideline 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.
5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
6. The wiring must be permanent. DO NOT USE AN EXTENSION
CORD! Use 14 GA. MINIMUM copper wire. Although the
Powered Attic Ventilator may be wired directly to power, we
advise that some type of shut off switch be installed in the
line. Please see the section on electrical wiring for suggested
wiring diagrams and instructions.
7. To reduce the risk of electric shock, do not use this fan with
any solid-state speed control device.
8. This unit must be grounded.
9. When applicable local regulations comprise more restrictive
installation and/or certification requirements, the aforementioned
requirements prevail on those of this document and the installer
agrees to conform to these at his own expense.
10. When performing installation, servicing or cleaning this unit, it
is recommended to wear safety glasses and gloves.

CAUTION
!
1. For 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
impeller, keep drywall spray, construction dust, etc. off power
unit.
3. This unit has an unguard impeller. Do not use in locations
readily accessible to people or animals.
4. Fan is equipped with a thermostat which may start fan
automatically. To reduce risk of injury or electric shock while
servicing or cleaning unit, switch power off at service panel
and lock service panel to prevent power from being switched
on accidentally. When the service disconnecting means cannot
be locked, securely fasten a prominent warning device, such
as a tag, to the service panel.
5. Home Ventilating Institute (HVI) recommends one square foot of
open air inlet per 300 cfm of fan capacity. 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 naturaldraft
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 opening in the roof. During extreme rain
and wind storms you may want to turn on your attic ventilator
to prevent excess moisture accumulation in your attic.
7. Records show, under ideal conditions, exposed galvanized steel
can remain rust free up to 100 years. For best protection, the
exposed portion of the roof sheet should be painted, especially
in areas of unusually high industrial air pollution. Follow paint
manufacturer’s instructions for good adhesion.
8. This ventilator is intended for roof installation.
9. The dome may be painted with a high-quality paint. Follow the
paint manufacturer’s recommendations for powder-coated steel.
10. Please read specification label on product for further information
and requirements.

1. Locate the ventilator at the center of the rear slope of the roof.
Place it as high on the roof as possible. The location should
be free of obstacles (T.V. leads, electrical lines, etc., see A in
illustration). If the ventilator top is level with the roof peak, it
can’t be seen from the street (see B in illustration). Keep this
approximate location in mind as you work from within the attic.
With the location set, measure down from the roof peak to the
center or the powered attic ventilator. Note this measurement.
2. From inside the attic, measure and place a mark at the point
which is one half the distance between 2 rafters, closest to
the position of the powered attic ventilator. Draw a line parralel
to the rafters. Measure down from the roof peak the distance
found in Step 1 and mark that measurement on the center
line between the 2 rafters.
3. Drill a guide hole through the roof at this mark.

4. Cut out the red and blue template found on the carton.
5. On the roof outside, mark 4 lines at 11½” from the guide hole
to form a 23" square. These lines will be used to center the
unit over the hole to be cut off.
Push a large nail through the center of the cardboard template
and into the guide hole.
Using the large half of the template, draw a 17½” diameter
circle on the shingles.
