READ AND SAVETHESE INSTRUCTIONS

WARNING

TOREDUCETHERISKOFFIRE,ELECTRICSHOCK,ORINJURY TO PERSONS, OBSERVETHE 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, 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-ratedconstruction 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 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.

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!Use14GA.MINIMUMcopperwire.AlthoughthePowered 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.This unit must be grounded.

8.Do not use this unit with any solid state speed control device (Models 356 and 358 only).

TOOLS AND MATERIALS REQUIRED

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 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.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 natural-draftgas 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.The Broan Model 353 Gable MountVentilator is available for side wall applications.

9.The dome may be painted with a high-qualitypaint. Follow the paint manufacturer's recommendations for PVC plastic or aluminum, as appropriate.

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.) If the ventilator top is level with the roof peak, it can't be seen from the street. Keep this approximate location in mind as you work from within the attic.

3. Drill a guide hole through the roof at this mark.

4. Cut out the template found on the carton.

6. Cut out the shingles inside of the circle.

7.Replace template over guide hole and draw a 14-3/8"diameter circle on the black paper or roof boards using the smaller half of the template.

9. Cut out the roof board(s) inside of the line.

10.For proper removal of roofing nails, draw a 22" square, centered around the hole.Remove nails holding shingles down from top two-thirdsof square.

8.Drill a large starting hole for the sabre saw just inside of the line.

11.Slide the flashing under the shingles. Start two-thirdsof the way down from the top of the 22" square. Do not bend the shingles any more than necessary. Center the ventilator over the hole.

12.Carefully lift shingles and nail flashing securely to the roof using galvanized roofing nails.

13.Using a good grade of roofing cement material, seal all of the shingles and heads of nails.

DO NOT seal the bottom edge of the flashing.

3.Replace the metal cover plate over the thermostat wiring box and fasten securely.

4.The thermostat setting determines the temperature at which the ventilator turns “on”. The ventilator automatically turns off when the attic temperature is 10OF lower than the thermostat.

If you want the ventilator to operate at a different temperature, insert a screwdriver into the slot and turn the indicator to the desired temperature.

The ventilator will now turn “ON” at this temperature and “OFF” 10OF lower.
