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.
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.
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.

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.
CAUTION
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power unit.
