WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE 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-rated
construction 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!
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.
7. This unit must be grounded.
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 Gable installation. The Broan Models
350, 355, 356 & 358 Roof Mount Ventilators are available for roof
mount applications.
9. Please read specification label on product for further information
and requirements.
10. 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.
11. If the fan makes excessive noise or if there is unusual noise or smells
of smoke, disconnect power supply and contact customer service.
If this fan is to be used to ventilate a garage:
A. Use only in single family, residential garages
B. Install in a GFCI protected branch circuit
C. 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
D. 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.
E. Run regularly if exposed to salty air environments
F. Extra cleaning may be required due to possible dirty surroundings

TOOLS & MATERIALS REQUIRED
PREPARE THE VENTILATOR
1. Unpack the ventilator and find:
1 - power unit with wiring box
4 - angle brackets
8 - sheet metal screws
2. 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
ventilator and louver will minimize
air recirculation.
CAUTION
1. For general ventilating use only. Do not use to exhaust hazardous or
explosive materials or vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced impellers,
keep drywall spray, construction dust, etc. off power unit.
CAUTION
 Electrical supplies
(to comply with codes)
 Nails
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 and 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.
Vents for attic side wall 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.
6. 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 mositure accumulaltion
in your attic.
