IMPORTANT SAFETY INSTRUCTIONS
WARNING:
TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Do not use this fan with any Solid-State Speed Control Device.
2. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
3. Before servicing or cleaning unit, switch power off at service
panel and lock service panel to prevent power from being
switched on accidentally.
4. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction.
5. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of fuel
burning equipment to prevent back drafting. 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.
6. “When cutting or drilling into wall or ceiling, Do Not dam-
age electrical wiring or other hidden utilities.”
7. CAUTION: This unit has an unguarded impeller. Do not
use in locations readily accessible to people or animals.
8. CAUTION: For general ventilation use only! Do not use
to exhaust hazardous or explosive materials and vapors.
GENERAL INFORMATION
1. For a power attic ventilator to effectively cool, it should pro
vide at least ten air changes per hour. To determine the prop
er CFM rating for a fan that will provide that number of air
changes, the total square footage of an attic must be multi
plied by .7. This will give the CFM rating for the fan needed
for an attic. Example: for a home with 1500 square feet of
attic space, the calculation would be as follows: 1500 x .7 =
1050. A fan with 1050 CFM rating would be needed for such
an attic. For dark roofs, 15%
should be added to this CFM cal-
culation. If a roof is particularly
steep, a slightly higher CFM
rating should be sought.
2.
The air intake area must be adequate for proper operation of the
power attic ventilator. One square foot
of free open air inlet per
300 CFM of fan capacity is recommended. See “Attic Intake
Area Required” section.
3. Along with the power attic ventilator’s summer advantages, it
also offers home protection during the win-ter. In winter
months, moist air creeps into the attic from the house below,
condensing on the underside of the roof boards, beams and
other materials. Excessive moisture can rapidly deteriorate
these materials. It can also penetrate insulation, reducing its
effectiveness and making the home less energy efficient. An
accessory dehumidistat can be used with this power attic
ventilator to automatically activate unit in the winter to combat
excessive moisture.
4. The power attic ventilator is designed for ventilating
attic space. Do not use unit to exhaust dirt, dust, grease or lint
laden air.

INST ALLATION
NOTE: For maximum operating efficiency, the proper intake air opening must be provided to allow replacement of exhaust air. The best
location for air intake is at the opposite end of the attic. See “Attic Intake Air Required” section.
1. This gable ventilator is designed to mount behind existing louvers in your attic. If a louver is not present and one must be installed, it
should
be mounted in the center of the upper most portion of the gable. The area of the louver should be greater than the outlet area of the
ventilator.
2. There are four sets of holes spaced 90º apart in the housing, providing a choice of four depth positions. Reversing the brackets makes
eight positions. Select the proper mounting holes to align the bracket and mounting structure on louvers.
3. Figure 1 shows the ventilator mounted directly against a gable louver. If the louver is sufficiently strong, the mounting brackets may be
nailed or screwed to it.
4. If mounting the vent directly to the gable louvers is undesirable, a pair of furring strips may be suspended vertically a minimum of 14 3/4
inches apart.
5. Figure 2 shows the ventilator mounted on a rectangular louver.
6. For better performance: Cover any open louvered area around vent with plywood or other suitable material. This will improve the efficiency
of
the air exchange between the attic and the outside. It will also prevent the thermostat from being directly affected by outside air.

MINIMUM A TTIC INT AKE AREA REQUIRED
Sufficient intake area must be provided in the attic to assure that the fan will not be overloaded and that it will deliver its rated CFM. This can
be accomplished with some type of attic venting such as gable louvers or under-eave vents. The table below shows the minimum intake area
needed for each fan installed.

WIRING INSTALLATION
WARNING: To reduce the risk of fire or electrical shock, do not use this fan with any solid state speed control device.
(This fan is designed to run on 120 volts, 60 Hz power only)
1. Wiring of this unit is done inside the attic. Remove cover from thermostat/junction box. Bring the power cable at least 6” into the box. Fasten
power cable to box with appropriate connector.
3
2. For standard installation, connect the two leads in the thermostat/junction box to the two supply leads. Attach ground wire from the supply
to the green ground screw in the box. See Fig. 3.
3. See Figure 4 for wiring dehumidistat to ventilator.
4. Replace cover to thermostat/junction box.
5. The ventilator will automatically turn “ON” when the attic temperature rises above 105º F and will turn “OFF” when the temperature drops
below 95º F.
