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 sepa-
rate 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:
National Fire Protection Association
Batterymarch Park
Quincy, Massachusetts 02269
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 nec-
essary. 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)
• 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.
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

LOWING: 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.
WARNING - TO REDUCE THE RISK OF SHOCK: This fan
must be installed with an isolating wall control/switch.
CAUTION: For General Ventilating Use Only. Do Not Use To
Exhaust Hazardous or Explosive Materials and Vapors.

-
LOWING: 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.
• DO NOT use this appliance with any solid state fan
speed control device.
• Failure to follow electrical requirements may result
in a fire.
