GENERAL
SURFACE COOKING UNITS
• If the top burner flame goes out,gas is still flowing to the
burner until the knob is turned to the “OFF” position.Do not
leave the burners “ON” unattended.
• 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.
• Be sure you know which knobs operate each burner.
Make sure you turned on the correct burner.
• To prevent burns, always be sure that the controls for all
burners are at the “OFF” position and all grates are cool
before attempting to remove them.
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 center burner. 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.
DEEP FAT FRYERS:
• Use extreme caution when moving the grease kettle or
disposing of hot grease.
