GENERAL
SURFACE COOKING UNITS
• Use Proper Pan Size – This appliance is equipped with one or
more surface units of different sizes. 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 burner will also improve efficiency.
• Never Leave Surface Units Unattended at High Heat Settings
– Boil overs may cause smoking and greasy spillovers may ignite.
• Make Sure Reflector Pans or Drip Bowls Are in Place –
Absence of these pans or bowls during cooking may subject
wiring or components underneath to damage.
• Protective Liners – Do not use aluminum foil to line surface unit
drip bowls or oven bottoms, except as suggested in the manual.
Improper installation of these liners may result in a risk of electric
shock, or fire.
• 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.
• Do Not Soak Removable Heating Elements – Heating
elements should never be immersed in water.
• Be sure you know which control pads operate each surface unit.
Make sure you turned on the correct surface unit.
SELF-CLEAN OVENS
• 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.
• Clean in the self-clean cycle only parts listed in this manual.
Before self-cleaning the oven, remove the broiler pan and any
utensils from the oven.
• Never keep pet birds in the kitchen – the health of birds is
extremely sensitive to the fumes released during an oven self-
clean cycle. Fumes may be harmful or fatal to birds. Move birds to
well-ventilated room.
• Important Instruction – In the event the self-clean mode “F”
code goes on, or three long beeps sound, oven is malfunctioning
in the self-clean mode. Turn off or disconnect appliance from
power supply and have serviced by a qualified technician.
IMPOR
IMPORT TANT SAFETY INSTRUCTIONS ANT SAFETY INSTRUCTIONS
VENTILATING HOODS:
• Clean Ventilating Hoods Frequently – Grease should not
be allowed to accumulate on hood or filter.
• When flaming foods under the hood, turn the fan on.
OVEN
• Use Care When Opening Door – Let hot air or steam escape
before you remove or replace food in the oven
• Do Not Heat Unopened Food Containers – Build-up of pressure
may cause container to burst and result in injury.
• Keep Oven Vent Ducts Unobstructed – the oven vent is located
above the left rear surface unit. this area could become hot during
oven use. Never block this vent and never place plastic or heat-
sensitive items on vent
• 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.
• Do Not allow aluminum foil or meat probe to contact heating
elements.
GLASS/CERAMIC COOKING SURFACES
• Do Not Cook on Broken Cook-Top – If cook-top should break,
cleaning solutions and spillovers may penetrate the broken cook-
top and create a risk of electric shock. Contact a qualified
technician immediately.
• Clean Cook-Top 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.
DEEP FAT FRYERS:
• Use extreme caution when moving the grease kettle or disposing
of hot grease.

Functional Operation
Bake Mode
Top and hidden bottom elements operate during
bake. Bake can be used to cook foods which are
normally baked. Oven must be preheated.
Broil Mode
Top element operates during broil. Broil can be
used to cook foods which are normally broiled.
Preheating is not required when using broil. All
foods should be turned at least once except fish,
which does not need to be turned.
Convection Bake / Roast Mode
Upper element, lower element, Rear element(some
model) and fan operate during convection bake.
Convection bake should be used for cooking
casseroles and roasting meats. Oven should be
preheated for best results when using convection
bake. Pans do not need to be staggered. Cooks
approximately 25% quicker than bake.
Cooking Guide
Refer to the owners manual for recommendations
of times and temperatures. Times, rack position,
and temperatures may vary depending on
conditions and food type. For best results, always
check food at minimum time. When roasting,
choose rack position based on size of food item.
