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
• 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 ELECTRIC SHOCK, do
not use this fan with any solid-state speed control device.
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRICAL 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 accidentally. 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, ELECTRICAL SHOCK,
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING: Installation
Work And Electrical Wiring Must Be Done By Qualified Person(s)
In Accordance 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. Follow 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 Heat-
ing, 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 outdoors.
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.
• Failure to follow electrical requirements may result
in a fire.
WARNING
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 ordi-
nances. Wire size and connections must conform with the
rating of the appliance. Copies of the standard listed above
may be obtained from:
