GABLE-MOUNT POWERED ATTIC VENTILATORMODEL 353MODEL 35316
READ AND SAVE THESE INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
- 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.
- Before servicing or cleaning the unit, switch power off at the 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.
- 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.
- 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 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.
- When cutting or drilling into a wall or ceiling, do not damage electrical wiring and other hidden utilities.
- 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.
- This unit must be grounded.
CAUTION
- For general ventilating use only. Do not use to exhaust hazardous or explosive materials or vapors.
- To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off the power unit.
- This unit has an unguarded impeller. Do not use in locations readily accessible to people or animals.
- The fan is equipped with a thermostat which may start the fan automatically. To reduce the risk of injury or electric shock while servicing and cleaning the unit, switch power off at the service panel and lock the 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.
- 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 is under the eaves with direct access to the attic. Vents for attic sidewall installations should be placed at the end of the house opposite the installed ventilator. Failure to provide these intakes could cause natural-draft gas appliances to backdraft.
- Your attic installation will create a screened opening into your attic space. During a heavy rainstorm, 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 gable. During extreme rain and wind storms, you may want to turn on your attic ventilator to prevent excess moisture accumulation in your attic.
- 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 the paint manufacturer’s instructions for good adhesion.
- This ventilator is intended for Gable installation. The Broan Models 350, 355, 356 & 358 Roof Mount Ventilators are available for roof mount applications.
- Please read the specification label on the product for further information and requirements.
- The wearing of safety glasses and gloves is recommended when installing, maintaining, or cleaning the unit to reduce the risk of injury that could be caused by the presence of thin metal and/or high moving parts.
- If the fan makes excessive noise or if there is unusual noise or smells of smoke, disconnect the power supply and contact customer service.
If this fan is to be used to ventilate a garage:
- Use only in single-family, residential garages
- Install in a GFCI protected branch circuit
- To help offset the risk posed by high concentrations of vapors from paints, glues, solvents, and fuels, install fan at least 18 inches (0.5m) above the floor
- NEVER run a vehicle or use a fuel-burning appliance inside of a garage. Deadly levels of carbon monoxide can build up in the area. Using this garage fan, or opening windows and doors, will NOT supply enough fresh air to eliminate the danger.
- Run regularly if exposed to salty air environments
- Extra cleaning may be required due to possible dirty surroundings.

PREPARE THE VENTILATOR
- Unpack the ventilator and find:1 – power unit with wiring box4 – angle brackets8 – sheet metal screws
- Fasten the four (4) angle mounting brackets to the housing using the eight (8) sheet metal screws provided. Position the bracket flush with the edge of the housing band. A close fit between the ventilator and louver will minimize air recirculation.
INSTALL THE VENTILATOR
The ventilator is designed to mount behind existing louvers. Find the type of louver you have in the examples below. If no louver exists, one must be installed. Louver should be mounted in the center of the upper portion of the gable as high as possible. For maximum efficiency, the area of the louver should be greater than the outlet area of the ventilator.
There is some loss in fan output because the louver blocks some of the airflows. Metal louvers have more open areas than wood louvers and usually allow more airflow.
When installing the ventilator behind louvers, you should seal off any louver area not covered by the ventilator housing band to prevent air leakage and recirculation. We suggest you mount the ventilator on a piece of plywood for the best sealing. Allow at least one square foot of air intake area for every 300 CFM of ventilator capacity.
CAUTION! When installing louvers or shutters, do not remove any existing structural members without providing alternate support members.
The ventilator can be mounted flush to a rectangular type louver by fastening through the mounting brackets to the frame of the louver.
On a wide louver, the brackets can first be fastened to the backside of two boards of the appropriate length and these boards can then be fastened to the frame.
With a narrow louver mounted between studs on 16” centers, two of the brackets can first be mounted to the backside of boards and the boards and other brackets nailed to the studs.
The ventilator can also be mounted off-center in an odd-shaped louver.
On large triangular louvers, mount to the frame or nail boards to the frame to provide a mounting surface for the ventilator. For the most effective installation, enclose the louver area not covered by the fan, with plywood or similar material.
Louvers that are smaller than the ventilator outlet will restrict air delivery. When this condition exists, a chamber should be built to properly direct the air through the louvers. A typical example of the suggested construction is shown.
An automatic shutter, Model 433, may also be installed to provide the necessary outlet for the fan. Installation instructions are provided with the Model 433 shutter.
WIRE THE VENTILATOR
- Remove the thermostat wiring box cover plate. Bring the power cable at least 6” into the thermostat wiring box. Fasten to box with the appropriate connector.
- For a standard installation, connect the two leads in the thermostat wiring box to the two power leads. Attach ground wire from the power cable to the green screw in the box.This diagram shows how to bypass the thermostat to turn the ventilator on or off manually.
This diagram shows how to wire a humidistat.
- Replace the metal cover plate over the thermostat wiring box and fasten securely.
- The thermostat setting determines the temperature at which the ventilator turns “on”. The ventilator automatically turns off when the attic temperature is 10 O F 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” 10 0F lower.
