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 el-
bows 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 discon-
nect (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, 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 questions, 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, ELECTRI-
CAL 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 exhaust-
ing 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 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 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
For residential use only.
