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.
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.
IMPORTANT SAFETY INSTRUCTIONS
• 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.

GENERAL INFORMATION
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
Top(broil) element, convection element and fan 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.
Convection Bake / Roast Mode
Top(broil) element, convection element 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.
