A.

A 115-volt, 60-Hz, AC-only, fused
electrical supply is required. The total
ampere load used, including the range
hood, must not exceed 90% of the rated
capacity of the circuit. The ampere rating

housing.

B.

The range hood must be
connected with copper wire only.

C.

The range hood can be
connected directly to the fused disconnect
(or circuit breaker) box through flexible
armored or nonmetallic sheathed copper
cable. A U.L.-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.

For power cord connected installations, 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 A
RANGE TOP GREASE FIRE:

Never leave surface units unattended at
high settings. Boilovers cause smoking and
greasy spillovers that may ignite. Heat oils
slowly on low or medium settings.

Always turn hood ON when cooking at high
heat or when cooking flaming foods.

Clean ventilating fans frequently. Grease
should not be allowed to accumulate on fan
or filter.

GREASE FIRE, OBSERVE THE FOLLOWING:

SMOTHER FLAMES with a close-fitting lid,
cookie sheet, or metal tray, then turn off the
burner. BE CAREFUL TO PREVENT BURNS. If the
flames do not go out immediately, EVACUATE
AND CALL THE FIRE DEPARTMENT.

Recommended vent length

Use 3-1/4" x 10" or 7" vent with a maximum
length of 26 feet for vent system. For best
performance, use no more than three 90°
elbows. To calculate the length of system
you need, add the equivalent feet for
each vent piece used in the system. See
the following examples.

Vented installation

Now start...

With range hood in kitchen.

Slide cardboard or hardboard under range
before moving range across floor to
prevent damaging floor covering.

Cover countertop, cooktop or set-in range
with a thick, protective covering to prevent
damaging countertop.

1.Disconnect and move freestanding

range from cabinet opening to provide
easier access to upper cabinet and rear
wall. Put a thick, protective covering over
cooktop, set-in range or countertop to
protect from damage or dirt.

2.Determine which venting method

(roof or wall venting or non-venting) you
need to use. This range hood is shipped for
non-vented installation.

If non-venting (recirculating) installation is
desired, follow instructions on Panel D.

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 laundry-type wall
caps.

Do not use plastic vent.

Vent system needed for installation is not
included. Wall or roof caps used must have
backdraft damper.

Determine which outside venting method
needs to be used. NOTE: If a non-vented
(recirculating) installation is desired, follow
instructions on Panel D.

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 7" round
vent system.

Figures 1-4 show common venting methods
and what types of materials are needed.

3.

Remove screws from vent baffle on
top of range hood. Remove vent baffle.

4.

Turn vent baffle and reinsert in slot in top of
range hood so that the word “Vented” is
facing up. Fasten vent baffle with screws.
