risk of fire,electric shock,or injury to persons.
Beginbyinsuringproperinstallationandservicing.
Follow the installation instructions which came
with this appliance. Be sure to have a qualified
technician to install and ground this appliance
before using.
Have the installer show you where the gas supply
shutoff valve is located so you will know how and
where to turn off the gas to the appliance.
Ifyousmellgas,theinstallerhasnotdoneaproper
jobofcheckingforleaks.You can havea smallleak
and therefore a faint gas smell if the connections
are not completely tight.Finding a gas leak is not
a “do-it-yourself” procedure. Some leaks can only
be found with the burner control in the “ON”
position and for your protection it must be done
by a qualified service technician.
WARNING:
Gasleaks mayoccur inyour systemand
result in a dangerous situation. Gas
leaks may not be detected by smell
alone. Gas suppliers recommend you
purchase and install an UL approved
gas detector. Install and use in
accordance with the manufacturer’s
instructions.
If by some chance a burner goes out and gas
escapes,open a window or a door to let the room
air out.Do not attempt to use the appliance until
the gas has had time to dissipate. Follow the
instructions on page 1,“What to do if You Smell
Gas”.
This appliance has been factory assembled for
natural gas. It should be correctly adjusted by a
qualified service technician or installer for the
type of gas that is used.
Do not repair or replace any part of this appliance
unless it is specifically recommended in this
manual.All other servicing should be referred to a
qualified technician.
Children should not be left alone or unattended
in an area where appliances are in use. They
should never be allowed to turn knobs, push
buttons,sit or stand on any part of an appliance.
Children in walkers, or children crawling can be
attracted to the round oven door handle and may
grab and open the oven door. This can result in
injury from the door being pulled open on a child,
or severe burns if the oven is in use and hot.
WARNING:
Donotstoreitemsofinteresttochildren
above or at the back of any appliance.
Children could be seriously injured if
they should climb onto the appliance to
reach these items.
Never store anything in the oven or on the
cooktop. Flammable materials can catch fire,
plasticitemsmaymeltor igniteandother types of
items could be ruined.
Do not hang articles from any part of the
appliance or place anything against the oven.
Some fabrics are quite flammable and may catch
on fire.
If the appliance is near a window be certain the
curtains do not blow over or near the cooktop
burners;they could catch on fire.
Do not use water on grease fires.Turn all burners
OFF, then smother fire with baking soda or use a
dry chemical or foam-type fire extinguisher.
Neverletclothing,potholders,orother flammable
materialscomeincontact with,ortoocloseto,any
burner or burner grate until it has cooled. Fabric
may ignite and result in personal injury.
Be certain to use only dry pot holders: moist or
damp pot holders on hot surfaces may cause
burns from steam. Do not use a towel or other
bulky cloth in place of pot holders.Do not let pot
holders touch hot burners,or burner grates.
For personal safety, wear proper apparel. Loose
fitting garments or hanging sleeves should never
be worn while using this appliance. Some
synthetic fabrics are highly flammable and should
not be worn while cooking.
Do not use aluminum foil to line any part of the

cooking performance and can damage the finish
of the oven or the cooktop parts.
WARNING:
This appliance is for cooking. Based on
safety considerations, never use the
oven or cooktop to warm or heat a
room. Also, such use can damage the
cooktop or oven parts.
When using the cooktop: Do not touch the
burner grates or the immediate surrounding
area. Areas adjacent to the burners may become
hot enough to cause burns.
When using the oven:Do not touch the interior
surfaces of the oven, the exterior area
immediately surrounding the door or the back
trim. The surfaces directly above the oven door
maybehotiftheovenhasbeenoperatedwiththe
door open, or if something has prevented the
door from sealing.
Never leave the cooktop unattended when
using high flame settings. Boil overs cause
smoking and greasy spill overs may ignite. More
importantly,iftheburnerflamesaresmotheredby
a severe boil over which effects the igniter,
unburned gas will escape into the room. See
page 1.
Only certain types of glass, heat-proof glass-
ceramic,ceramic,earthen ware,or other glazed
utensils are suitable for cooktop use. This type
of utensil may break with sudden temperature
changes. Use only on low or medium flames
settings according to the manufacturer’s
directions.
Do not heat unopened food containers; a build
up of pressure may cause the container to burst.
During cooking, set the burner control so that
the flame heatsonly the bottom ofthe pan and
does not extend beyond the bottom of the pan.
This could heat and/or melt the handles.
Always use utensils that have flat bottoms
large enough to cover the burner. The use of
undersized utensils will expose a portion of the
flame to direct contact and may result in ignition
of clothing.
To minimize burns, ignition of flammable
materials and unintentional spill overs, position
handles of utensils inward so they do not extend
over adjacent work areas, cooking areas, or the
edge of the cooktop.
Hold the handle of the pan to prevent
movement of the utensil when stirring or turning
food.
GREASE IS FLAMMABLE. Let hot grease cool
before attempting to handle it. Avoid letting
grease deposits collect around the cooktop
burners.Clean after each use or boil over.
For proper lighting and performance of the
cooktop burners,keep the burner ports clean. It
may be necessary to clean these when there is a
boil over or when the burner does not light,even
though the electronic igniters click.
Clean the cooktop with caution. Avoid steam
burns; do not use a wet sponge or cloth to clean
thecooktopwhileitishot.Somecleanersproduce
noxious fumes if applied to a hot surface. Follow
directions provided by the cleaner manufacturer.
Be sure all the range and/or cooktop controls are
turned off and the appliance is cool before using
any type of aerosol cleaner on or around the
appliance. The chemical that produces the
spraying action could, in the presence of heat,
ignite or cause metal parts to corrode.
Place oven racks in desired position while the
oven is cool. If a rack must be moved while the
oven is hot,do not let the pot holders contact the
hot interior of the oven.
Use care when opening the oven door. Let hot
air or steam escape before removing or replacing
foods.
Do not rub, damage, move or remove the door
gasket.Itisessentialforagoodsealduringbaking.
Clean the ventilator hood and filters above the
range or cooktop frequently so grease from
cooking vapors does not accumulate on them.
Turn the ventilator OFF in case of fire or when
intentionally “flaming” liquor or other spirits on
the cooktop. The blower, if in operation, could
unsafely spread the flames.
Do not obstruct the flow of combustion or
ventilation air to the appliance.Be sure a fresh air
supply is available.
For safety reasons and to avoid damage to the
appliance never sit, stand, or lean on the oven
door or cooking surface.
Service should only be done by authorized
technicians. Technicians must disconnect the
power supply before servicing this appliance.
