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.

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.
