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, remote blowers should transition to 9" round duct
as soon as possible. If small ducting is used, it should be
transition to 9" round as soon as possible.
WARNING - To Reduce The Risk Of Fire, Use Only Metal
Ductwork.
WARNING
!
• 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.
ELECTRICAL REQUIREMENTS
A 120 volt, 60 Hz AC-only electrical supply is required on
a separate 15 amp circuit, fused on both sides of the line.
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).
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, 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 off power at service panel and lock service panel
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.
Installation Work And Electrical Wiring Must Be Done By
Qualified Person(s) In Accordance With All Applicable
CodesAnd Standards, Including Fire-Rated Construction.
When cutting or drilling into wall or ceiling, do not dam-
age electrical wiring and other hidden utilities. Ducted
fans must always be vented to the outdoors.
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
ProtectionAssociation (NFPA), and theAmerican Society
for Heating, Refrigeration andAir Conditioning Engineers
(ASHRAE), and the local code authorities.
CAUTION: For General Ventilating Use Only. Do Not
Use To Exhaust Hazardous or Explosive Materials and
Vapors.
For Remote Blowers only: CAUTION: This unit has an un-
guarded impeller. Do Not Use In Locations Readily Accessible
To People Or Animals.
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.
