GABLE VENTILATOR
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 manufac-
turer. 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.
