SPACE VENTILATOR
READ AND SAVE THESE INSTRUCTIONS.
ATTENTION
This ventilator’s flashing plate may possibly have been distorted during shipping and handling. Any
such distortion does not represent defective product and is not returnable for that reason. Flashing
material is purposely designed to be soft and flexible in order to allow the flashing plate to conform to the contour of the roof.
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 damage 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 INFORMA TION
1. For a power attic ventilator to effectively cool, it should provide at least ten air changes per hour. To
determine the proper CFM rating for a fan that will provide that number of air changes, the total square
footage of an attic must be multiplied 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 calculation. 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
winter. 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. See “Attic Intake Area Required” section.
1. The unit should be installed as close to the center of the roof ridgeline as possible on the rear slope
of the roof. The uppermost portion of ventilator dome should be just below ridge level. See Fig. 1.
2. After locating unit in desired installation position on top of roof, measure from the unit to the ends of
the roof and to the ridgeline. Using these measurements, locate the spot inside the attic directly under
the spot on the roof where the unit has been placed. Locate a centerline position between two rafters
as close as possible to this established position and drill a pilot hole through the roof from the inside.
See Fig. 2.

3. Cut a rectangular hole centered around the drilled hole 14 1/2” wide by 17” long. Be sure the 17” side
is parallel to the rafters.
4. With mounting plate parallel to ridgeline of roof, slide the upper outer flange of the plate under the row
of shingles just above the cutout so that the housing portion of unit can be centered in the cutout
opening. See Fig. 3.
5. Caulking or roofing cement must be used to seal the mounting plate to the roof, especially bottom and
side areas of flange not covered by shingles.
6. With unit in place, nail the top left corner and top right corner of flange to roof decking and rafters with
galvanized roof nails. This is accomplished by nailing directly through the aluminum plate. Nail the bottom of the flange the same way. Check to be sure all shingles are securely and neatly in place over
top portion of flange. See Fig. 3. Caulking nail heads is recommended.
7. Installation should be water checked by using a garden hose and spraying water directly on top of
unit. Do not spray water directly into vent opening.

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.
