others is very important.

We have provided many important
safety messages in this manual and
on your appliance. Always read and
obey all safety messages.

This is the safety alert symbol.
This symbol alerts you to

potential hazards that can kill
or hurt you and others. All safety
messages will follow the safety alert
symbol and either the word “DANGER”
or “WARNING”. These words mean:

DANGER

instructions.

follow

WARNING

You can be killed or seriously injured
if you don’t follow instructions.

All safety messages will tell you what
the potential hazard is, tell you how to
reduce the chance of injury, and tell
you what can happen if the
instructions are not followed.

Important: Observe all governing
codes and ordinances.

Proper installation is your
responsibility. Make sure you have
everything necessary for correct
installation. It is the responsibility of
the installer to comply with the
clearances specified.

Check the location where the range
hood will be installed. The location
should be away from strong draft
areas, such as windows, doors, and
strong heating vents.

Mobile home installation

The installation of this range hood
must conform to the Manufactured
Home Construction Safety
Standards, Title 24 CFR, Part 328
(formerly the Federal Standard for
Mobile Home Construction and
Safety, Title 24, HUD, Part 280) or
when such standard is not
applicable, the Standard for
Manufactured Home Installation

WARNING — TO REDUCE THE
RISK OF FIRE, ELECTRIC
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

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 — To reduce the r isk
of fire, use only metal ductwork.

This unit must be grounded.

Electrical
requirements

Important: Observe all governing
codes and ordinances.

It is the customer’s responsibility:

•To contact a qualified electrical
installer.

•To assure that the electrical
installation is adequate and in
conformance with National
Electrical Code, ANSI/NFPA 70
— latest edition*, or CSA
Standards C22.1-94, Canadian
Electrical Code, Part 1 and
C22.2 No.0-M91 - latest
edition** and all local codes
and ordinances.

A separate ground wire must be
used. It is recommended that a
qualified electrician determine that
the ground path is adequate.

A 120-volt, 60-Hz, AC-only, fused
electrical system is required. A
separate 15-amp circuit is
recommended.

Do not ground to a gas pipe.

Check with a qualified electrician if
you are not sure range hood is
properly grounded.

Do not have a fuse in the neutral or
ground circuit.

IMPORTANT:
Save Installation Instructions for
electrical inspector’s use.

The range hood must be connected
with copper wire only.

The range hood should be
connected directly to the fused
disconnect (or circuit breaker) box
through flexible armored or
nonmetallic sheathed copper cable.
A U.L.- or C.S.A.-listed strain relief
must be provided at each end of the
power supply cable. Wire sizes
(COPPER WIRE ONLY) and
connections must conform with the
rating of the appliance as specified
on the model/serial rating plate.

Wire sizes must conform to the
requirements of the National
Electrical Code ANSI/NFPA 70 —
latest edition*, or CSA Standards

ordinances.

A U.L.- or C.S.A.-listed conduit
connector must be provided at each
end of the power supply cable (at
the range hood and at the junction
box).

In U.S. only: For power cord
connected installations, a U.L.­listed range hood cord-connection
kit MUST be used. Cord kit has not
been evaluated for use in Canada.

Venting requirements

Venting system must terminate to
the outside.

Do not terminate the vent in an attic
or other enclosed space.

Do not use four-inch (10.2 cm)
laundry-type wall caps.

Do not use plastic vent.

Vent system needed for installation
is not included.

Determine which outside venting
method needs to be used. It is
recommended that the vent
system be installed before
installing the hood.

NOTE: If a non-vented
(recirculating) installation is
desired, follow instructions on
Page 5.

The length of the vent system and
number of elbows should be kept
to a minimum to provide efficient
performance. The size of the vent
system should be uniform. Do
Not install two elbows together.
Use duct tape to seal all joints in
the vent system. Vent system can
terminate either through the roof
or wall. Use caulking to seal
exterior wall or roof opening
around exhaust hood. For the
most efficient and quiet operation,
it is recommended that the range
be vented vertically through the

roof through 6" (15.2 cm) round
vent system.

Figures 1 and 2 show common
venting methods and what types
of materials are needed.

Recommended vent length

Use 3-1/4" x 10" (8.3 x 25.4 cm) or
6" (15.2 cm) or larger round vent
with a maximum length of 70 feet
(21.3 m) for vent system. If 7"
(17.8 cm) round vent is used, the
maximum length is 80 ft. (24.4 m).
For best performance, use no
more than three 90° elbows. To
calculate the length of system
you need, add the equivalent feet
(meters) for each vent piece used
in the system. See the examples
on the next page.
