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. If it is used, each foot
of flexible ductwork used is equivalent to two feet of straight
metal ductwork when calculating the ductrun length. Thus,
a flexible elbow equals two standard elbows.
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. For best
results, internal blowers should use 6" round ducting and
remote blowers should transition to 10" round duct as soon
as possible. If small ducting is used, it should be transitioned
to 9 or 10" round as soon as possible.
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
dedicated 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:

Batterymarch Park
Quincy, Massachusetts 02269
• 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.
SUITABLE FOR USE WITH SOLID STATE SPEED CONTROLS.
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRICAL
SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
A) Use this unit only in the manner intended by
the manufacturer. If you have any questions, contact the
manufacturer.
B) 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 FIRE, ELECTRICAL
SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
A) Installation Work And Electrical Wiring Must Be Done
By Qualified Person(s) In Accordance With All Applicable
Codes And Standards, Including Fire-Rated Construction.
B) 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 Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
C) When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
D) Ducted fans must always be vented to the outdoors.
WARNING
• Electrical ground is required on this range hood.
• 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 range hood is properly
grounded.
• Failure to follow electrical requirements may result
in a fire.
WARNING
For residential use only.

Cold Weather installations
(NOT INCLUDED)
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.
CAUTION: To reduce risk of fire and to properly exhaust air, be
sure to duct air outside - do not vent exhuast air into spaces
within walls or ceilings or into attics, crawl spaces or garages.
