VENTING REQUIREMENTS
Determine which venting method is best for your application.
Ductwork can extend either through the wall or the roof.
The length of the ductwork and the number of elbows should
be kept to a minimum to provide efficient performance. The
size of the ductwork should be uniform. Do not install two
elbows together. Use duct tape to seal all joints in the ductwork
system. Use caulking to seal exterior wall or floor opening
around the cap.
Flexible ductwork is not recommended. Flexible ductwork
creates back pressure and air turbulence that greatly
reduces performance.
Make sure there is proper clearance within the wall or floor
for exhaust duct before making cutouts. Do not cut a joist or
stud unless absolutely necessary. If a joist or stud must be
cut, then a supporting frame must be constructed.

WARNING - To Reduce The Risk Of Fire, Use Only Metal
Ductwork.
ELECTRICAL REQUIREMENTS
A 120 volt, 60 Hz AC-only electrical supply is required on a
separate 15 amp fused circuit. A time-delay fuse or circuit
breaker is recommended. The fuse must be sized per local
codes in accordance with the electrical rating of this unit as
specified on the serial/rating plate located inside the unit
near the field wiring compartment. THIS UNIT MUST BE
CONNECTED WITH COPPER WIRE ONLY. Wire sizes
must conform to the requirements of the National Electrical
Code, ANSI/NFPA 70 - latest edition, and all local codes and
ordinances. Wire size and connections must conform with the
rating of the appliance. Copies of the standard listed above
may be obtained from:

• Venting system MUST terminate outside the
home.
• DO NOT terminate the ductwork in an attic or
other enclosed space.
• DO NOT use 4" laundry-type wall caps.
• Flexible-type ductwork is not recommended.
• DO NOT obstruct the flow of combustion and
ventilation air.
• Failure to follow venting requirements may result
in a fire.
This appliance should be connected directly to the fused
disconnect (or circuit breaker) through flexible, armored
or nonmetallic sheathed copper cable. Allow some slack
in the cable so the appliance can be moved if servicing
is ever necessary. A UL Listed, 1/2" conduit connector
must be provided at each end of the power supply cable
(at the appliance and at the junction box)
When making the electrical connection, cut a 1 1/4" hole
in the wall. A hole cut through wood must be sanded until
smooth. A hole through metal must have a grommet.
WARNING - TO REDUCE THE RISK OF FIRE OR ELEC-
TRIC SHOCK, do not use this fan with any solid-state
speed control device.
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRI-
CAL SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING: Use this unit only in the manner
intended by the manufacturer. If you have any ques-
tions, contact the manufacturer.
Before servicing or cleaning unit, switch power off
at service panel and lock the service disconnecting
means to prevent power from being switched on ac-
cidentally. When the service disconnecting means
cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
CAUTION: For General Ventilating Use Only. Do Not
Use To Exhaust Hazardous or Explosive Materials
and Vapors.
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRI-
CAL SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING: Installation Work And Electrical
Wiring Must Be Done By Qualified Person(s) In Ac-
cordance With All Applicable Codes And Standards,
Including Fire-Rated Construction.
Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent backdrafting. Fol-
low the heating equipment manufacturer's guideline
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 wall or ceiling, do not
damage electrical wiring and other hidden utilities.
Ducted fans must always be vented to the out-
doors.
WARNING
• Electrical ground is required on this rangehood.
• If cold water pipe is interrupted by plastic,
nonmetallic gaskets or other materials, DO NOT
use for grounding.
• DO NOT ground to a gas pipe.
• DO NOT have a fuse in the neutral or grounding
circuit. A fuse in the neutral or grounding circuit
could result in electrical shock.
• Check with a qualified electrician if you are in
doubt as to whether the rangehood is properly
grounded.
• DO NOT use this appliance with any solid state
fan speed control device.
• Failure to follow electrical requirements may

Cold Weather installations
An additional back draft damper should be installed to minimize
backward cold air flow and a nonmetallic thermal break should
be installed to minimize conduction of outside temperatures
as part of the vent system. The damper should be on the cold
air side of the thermal break. The break should be as close as
possible to where the vent system enters the heated portion
of the house.
