IMPORTANT SAFETY
INSTRUCTIONS
•If there is a fire in the oven
during baking, smother the fire
by closing the oven door and
turning the oven off or by using
a multi-purpose dry chemical or
foam-type fire extinguisher.
•Do not use any type of foil or
liner to cover the oven bottom or
anywhere in the oven, except as
described in this manual. Oven
liners can trap heat or melt,
resulting in damage to the
product and risk of shock, smoke
or fire.
•Use Only Dry Potholders – Moist
or damp potholders on hot
surfaces may result in burns
from steam. Do not let potholder
touch hot heating elements. Do
not use a towel or other bulky
cloth.
•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 or other
flammable materials contact
surface units or areas near units
until they have had sufficient
time to cool. Among these areas
are the coil elements, the
cooktop, and surfaces facing the
cooktop.
•DO NOT TOUCH HEATING
ELEMENTS OR INTERIOR
SURFACES OF OVEN – Heating
elements may be hot even
though they are dark in color.
Interior surfaces of an oven
become hot enough to cause
burns. During and after use, do
not touch, or let clothing or other
flammable materials contact
heating elements or interior
surfaces of oven until they have
had sufficient time to cool. Other
surfaces of the appliance may
become hot enough to cause
burns – among these surfaces
are oven vent openings and
surfaces near these openings,
oven doors, and windows of
oven doors.
•Do Not Cook on Broken Cooktop
–If cooktop should break,
cleaning solutions and spillovers
may penetrate the broken
cooktop and create a risk of
electric shock. Contact a
qualified technician
immediately.
•Avoid scratching or impacting
glass doors, cooktops, or control
panels. The cooktop can be
scratched with items such as
knives, sharp instruments, rings
or other jewelry, and rivets on
clothing. Doing so may lead to
glass breakage.
READ AND SAVE THESE INSTRUCTIONS

IMPORTANT SAFETY
INSTRUCTIONS
•Never Leave Surface Units
Unattended at High Heat
Settings – Boilover causes
smoking and greasy spillovers
that may ignite.
•Do Not Heat Unopened Food
Containers – Build-up of
pressure may cause container to
burst and result in injury.
•Wear Proper Apparel – Loose-
fitting or hanging garments
should never be worn while
using the appliance.
•Use Proper Pan Size – This
appliance is equipped with one
or more surface units of different
size. Select utensils having flat
bottoms large enough to cover
the surface unit heating
element. The use of undersized
utensils will expose a portion of
the heating element to direct
contact and may result in
ignition of clothing. Proper
relationship of utensil to heating
element will also improve
efficiency.
•Glazed Cooking Utensils – Only
certain types of glass,
glass/ceramic, ceramic,
earthenware, or other glazed
utensils are suitable for range-
top service without breaking due
to the sudden change in
temperature.
•Utensil Handles Should Be
Turned Inward and Not Extend
Over Adjacent Surface Units – To
reduce the risk of burns, ignition
of flammable materials, and
spillage due to unintentional
contact with the utensil, the
handle of a utensil should be
positioned so that it is turned
inward, and does not extend
over adjacent surface units.
•If power is lost to an electric
cooktop with knob surface unit
controls while a surface unit is
ON, the surface unit will turn
back on as soon as power is
restored. In the event of power
loss, failure to turn all surface
unit knobs to the OFF position
may result in ignition of items on
or near the cooktop, leading to
serious injury or death.
•Do not place or store items that
can melt or catch fire on the
glass cooktop, even when it is
not being used. If the cooktop is
inadvertently turned on, they
may ignite. Heat from the
cooktop or oven vent after it is
turned off may cause them to
ignite also.
•Use Care When Opening Door –
Let hot air or steam escape
before removing or replacing
food.
READ AND SAVE THESE INSTRUCTIONS

10
IMPORTANT SAFETY
INSTRUCTIONS
•Never broil with door open.
Open-door broiling is not
permitted due to overheating of
control knobs.
•Care must be taken to prevent
aluminum foil and meat probes
from contacting heating
elements.
•Placement of Oven Racks –
Always place oven racks in
desired location while oven is
cool. If rack must be moved
while oven is hot, do not let
potholder contact hot heating
element in oven.
•Injuries may result from misuse
of appliance doors or drawers
such as stepping, leaning, or
sitting on the doors or drawers.
•Storage in or on Appliance –
Flammable materials should not
be stored in an oven or near
surface units.

flammable vapors and liquids.
•Do not let cooking grease or
other flammable materials
accumulate in or near the range.
Grease in the oven or on the
cooktop may ignite.
•Keep Oven Vent Ducts
Unobstructed.
•Clean Cooktop With Caution – If
a wet sponge or cloth is used to
wipe spills on a hot cooking
area, be careful to avoid steam
burn. Some cleaners can
produce noxious fumes if
applied to a hot surface.
•Use care when touching the
cooktop. The glass surface of the
cooktop will retain heat after the
controls have been turned off.
•Do Not Soak Removable
Heating Elements – Heating
elements should never be
immersed in water.
•Do Not Clean Door Gasket – The
door gasket is essential for a
good seal. Care should be taken
not to rub, damage, or move the
gasket.
•Do Not Use Oven Cleaners – No
commercial oven cleaner or
oven liner protective coating of
any kind should be used in or
around any part of the oven.
