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.
IMPORTANT SAFETY INSTRUCTIONS
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.
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.
• Do Not Leave Children Alone - Children should not be left alone
or unattended in area where appliance is in use. They should
never be allowed to sit or stand on any part of the appliance.
• Never Use Your Appliance for Warming or Heating the Room.
• Storage in or on Appliance – Flammable materials should not
be stored in an oven or near surface units. Be sure all packing
materials are removed from the appliance before operating it.
Keep plastics, clothes and paper away from parts of the appliance
that may become hot
• Wear Proper Apparel – Loose-fitting or hanging garments should
never be worn while using the appliance.
• Do Not Use Water on Grease Fires – Turn off oven to avoid
spreading the flame. Smother the fire or flame by closing the door
or use dry chemical, baking soda or foam- type extinguisher.
• 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.
WARNING
• DISCONNECT power supply cord from
the outlet before servicing.
• Replace all panels and parts before
operating.
• RECONNECT all grounding devices.
- Failure to do so can result in severe personal
injury, death or electrical shock.

Rating Label
Model numbers are recorded on the rating label.
Rating label is located on the lower front left corner
of the oven frame. It can be seen by opening the
storage drawer or warming drawer. Before ordering
parts, write down the correct model and serial
number from rating label. This avoids incorrect
shipments and delays. Please refer to parts
reference material when ordering replacement parts.
Functional Operation
Bake Mode
Upper and rear 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. All foods
should be turned at least once except fish, which
does not need to be turned.
USING YOUR RANGE
GENERAL INFORMATION
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. Difference
between bake and convection mode is fan speed
and amount of cycling time. When cook with bake
mode, fan speed and amount of cycle tine is lower
than convection mode. Difference between
convection bake and convection roast at high
temperature (More 330F) is that amount of broil
cycling time. Broil cycling time of convection roast is
more than twice than convection bake mode.
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.
