Important Safety Instructions

9 WARNING

When properly cared for, your new appliance has
been designed to be safe and reliable. Read all
instructions carefully before use. These precautions
will reduce the risk of burns, electric shock, fire and
injury to persons. When using kitchen appliances,
basic safety precautions must be followed, including
those in the following pages.

Gas Appliance Safety

with the burner control in the ON position and this must
be done by a qualified service technician. See “WHAT

TO DO IF YOU SMELL GAS” on page 2.

• During a power failure, only the cooktop burners can
be lit manually.

• To prevent carbon monoxide build-up, do not block
appliance air vents.

• For proper lighting and performance of burners, keep
igniters clean and dry.

9 WARNING

State of California Proposition 65 Warnings:

This product contains chemicals known to the State
of California to cause cancer, birth defects or other
reproductive harm.

IMPORTANT SAFETY NOTICE: The California

•
Safe Drinking Water and Toxic Enforcement Act
requires the Governor of California to publish a list of
substances known to the state to cause cancer, birth
defects or other reproductive harm, and requires
businesses to warn customers of potential exposure to
such substances.
The burning of gas cooking fuel can generate some by­products which are on the list. To minimize exposure to
these substances, always operate this unit according to
the instructions contained in this booklet and provide
good ventilation.

• Birds have very sensitive respiratory systems. Keep
pet birds out of the kitchen or other rooms where
kitchen fumes could reach them. Kitchen fumes such
as overheating margarines and cooking oils may be
harmful.

• Have the installer show you where the gas shut-off
valve is located.

• If a burner goes out and gas escapes, open windows
and doors. Wait until gas dissipates before using the
appliance.

• If you smell gas, your installer has not done a proper
job of checking for leaks. If the connections are not
perfectly tight, you can have a small leak and,
therefore, a faint smell. Finding a gas leak is not a "do-

it-yourself" procedure. Some leaks can only be found

Fire Safety

• Do not use aluminum foil to line any part of the
cooktop.

• Set the burner control so that the flame does not
extend beyond the bottom of the pan.

• Use this appliance only for its intended use as
described in this manual. For example, never use the
appliance for warming or heating the room. Never use
the appliance for storage.

English 2

9 IMPORTANT SAFETY INSTRUCTIONS

READ AND SAVE THESE INSTRUCTIONS

• Do not allow aluminum foil, plastic, paper or cloth to
come in contact with a hot burner or grate. Do not allow
pans to boil dry.

• If the cooktop is near a window, forced air vent, or fan,
be certain that flammable materials such as window
coverings do not blow over or near the burners or
elements. They could catch on fire.

• Always have a working smoke detector near the
kitchen.

• Never leave the cooktop unattended when in use.
Boilovers cause smoking and greasy spillovers may
ignite.

WARNING—TO REDUCE THE RISK OF A RANGE

•
TOP GREASE FIRE:

a) 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.

b) Always turn hood ON when cooking at high heat or

when flambéing food (i.e. Crepes Suzette, Cherries
Jubilee, Peppercorn Beef Flambe').

c) Clean ventilating fans frequently. Grease should

not be allowed to accumulate on fan or filter.

d) Use proper pan size. Always use cookware

appropriate for the size of the surface element.

• In the event that personal clothing or hair catches fire,
drop and roll immediately to extinguish flames.

• Smother flames from food fires other than grease fires
with baking soda. Never use water on cooking fires.

• Take care that drafts like those from fans or forced air
vents do not push the flames so that they extend
beyond the edges of the pan.

3) The fire department is being called.

4) You can fight the fire with your back to an exit.

5) Have an appropriate fire extinguisher
available, nearby, highly visible and easily
accessible near the oven.

• Whenever possible, do not operate the ventilation
system during a cooktop fire. However, do not reach
through fire to turn it off.

Burn Prevention

• DO NOT TOUCH SURFACE UNITS OR AREAS NEAR
UNITS - Surface units may be hot even though they
are dark in color. Areas near surface units may become
hot enough to cause burns. During and after use, do
not touch, or let clothing, potholders, or other
flammable materials contact surface units or areas
near units until they have had sufficient time to cool.
Among these areas are the cooktop and areas facing
the cooktop.

• Do not heat or warm unopened food containers. Build­up of pressure may cause the container to burst and
cause injury.

• Use high heat settings on the cooktop only when
necessary. To avoid bubbling and splattering, heat oil
slowly on no more than a low-medium setting. Hot oil is
capable of causing extreme burns and injury.

• Never move a pan of hot oil, especially a deep fat fryer.
Wait until it is cool.

CAUTION:

All igniters spark when any single burner is turned on. Do
not touch any of the burners when the cooktop is in use.

WARNING:

TO REDUCE THE RISK OF INJURY TO PERSONS IN
THE EVENT OF A GREASE FIRE, OBSERVE THE
FOLLOWING:

a) 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.

b) NEVER PICK UP A FLAMING PAN - You may be

burned.

c) DO NOT USE WATER, including wet dishcloths or

towels - a violent steam explosion will result.

d) Use an extinguisher ONLY if:

1) You know you have a Class ABC extinguisher,
and you already know how to operate it.

2) The fire is small and contained in the area
where it started.

English 3

Child Safety

• When children become old enough to use the
appliance, it is the legal responsibility of the parents or
legal guardians to ensure that they are instructed in
safe practices by qualified persons.

• Do not allow anyone to climb, stand, lean, sit, or hang
on any part of an appliance. This can damage the
appliance and potentially cause severe injury.

• Do not allow children to use this appliance unless
closely supervised by an adult. Children and pets
should not be left alone or unattended in the area
where the appliance is in use. They should never be
allowed to play in its vicinity, whether or not the
appliance is in use.

CAUTION:

Items of interest to children should not be stored in an
appliance, in cabinets above an appliance or on the

9 IMPORTANT SAFETY INSTRUCTIONS

READ AND SAVE THESE INSTRUCTIONS

backsplash. Children climbing on an appliance to reach
items could be seriously injured.

Cleaning Safety

• Do not clean the appliance while it is still hot. Some
cleaners produce noxious fumes when applied to a hot
surface. Wet clothes or sponges can cause burns from
steam.

• After a spill or boilover, turn off the burner and allow the
cooktop to cool. Clean around the burner and burner
ports. After cleaning, check for proper operation.

Cookware Safety

• Hold the handle of the pan when stirring or turning
food. This helps prevent spills and movement of the
pan.

• Use Proper Pan Size. The use of undersized cookware
will expose a portion of the heating element or burner
to direct contact and may result in ignition of clothing.
Select cookware having flat bottoms large enough to
cover the surface heating unit. This appliance is
equipped with one or more surface units of different
size. Proper relationship of cookware to heating
element or burner will also improve efficiency.

• Always position handles of utensils inward so they do
not extend over adjacent work areas, burners, or the
edge of the cooktop. This reduces the risk of fires,
spills and burns.

• Adjust burner flame size so that it does not extend
beyond the edge of the cookware. Proper relationship
of cookware to burner flame reduces safety risks.

• Use only certain types of glass, heatproof glass,
ceramic, earthenware, or other glazed utensils that are
suitable for cooktop use.

Proper Installation and Maintenance

• Have the installer show you the location of the circuit
breaker or fuse. Mark it for easy reference.

• This appliance must be properly installed and
grounded by a qualified technician. Connect only to
properly grounded outlet. Refer to Installation
Instructions for details.

use only. It is not approved for outdoor use. See

“STATEMENT OF LIMITED PRODUCT WARRANTY”
on page 18. If you have any questions, contact the

manufacturer.

• Do not store or use corrosive chemicals, vapors,
flammables or nonfood products in or near this
appliance. It is specifically designed for use when
heating or cooking food. The use of corrosive
chemicals in heating or cleaning will damage the
appliance and could result in injury.

• Do not operate this appliance if it is not working
properly, or if it has been damaged. Contact an
authorized service provider.

• Do not repair or replace any part of the appliance
unless specifically recommended in this manual. Refer
all servicing to a factory authorized service center.
