READ AND SAVE THESE INSTRUCTIONS
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, disable the ventilator by cover-
ing the solar panel with cardboard or disconnecting the wires
from the motor terminals (note wire locations when disconnect-
ing).
3. Installation work must be done by a qualified person(s) in ac-
cordance with all applicable codes and standards, including
fire-rated construction codes and standards.
4. If removing an existing 120 VAC powered attic ventilator, use
only a qualified person(s) to remove any electrical wiring in
accordance with all applicable codes and standards.
5. 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 manufac-
turer'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 Condition-
ing Engineers (ASHRAE), and the local code authorities.

CAUTION
1. For general ventilating use only. Do not use to exhaust hazard-
ous 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. This ventilator operates when the solar panel is exposed to
sun light. To reduce risk of injury while installing, servicing or
cleaning unit, cover the solar panel with cardboard or discon-
nect the wires from the motor terminals (note wire locations
when disconnecting).
5. The recommended open air inlet for this ventilator is 2 square
feet. 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-draft gas 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 condi-
tion with all attic ventilators and will not cause any damage to
the structure. We recommend that you do not store any valu-
able articles directly under the fan opening in the roof.
7. This ventilator is intended for roof installation. Broan Models
353, 345GOBK & 345GOWW Gable Mount Ventilators are
available for side wall applications.
8. The plastic ventilator dome and base may be painted with
high quality paint. Follow the paint manufacturer's recommen-
dations for acrylic and ABS plastic as appropriate. Take care
to avoid getting paint on the solar panel.
9. This ventilator includes a permanently lubricated motor. Do
not oil or disassemble.
10. The installation instructions contained in this document are
only a recommendation and individual professionals may
have their own methods of installation. If your roof has an
existing warranty, installation of this product by anyone other
than those who installed the roof may jeopardize any future
warranty claim. Please check with the original installer of your
roof if this is a concern.
11. When working with asphalt shingles in cold weather (below
40 F), take care to avoid damage to the shingle edges and
o
corners.
12. For installations in climates where cold weather condensation
is not a concern, Broan Model CWT45 thermostat is available.
It disconnects power to the motor when the temperature drops
below 50 o F. Power is applied to the motor when the tempera-
ture reaches 61 F.
