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.
• Be sure your appliance is properly installed and grounded by
a qualified technician.
• Do not repair or replace any part of the appliance unless
specifically recommended in the manual.
All other servicing should be referred to a qualified technician.
• Always disconnect power to appliance before servicing by
removing the fuse or switching off the circuit breaker
• DO NOT step or sit on the door and install the Anti-Tip
Bracket packed with range.
- The range could be tipped and injury might result from
spilled hot liquid, food, or the range itself.
- If the range is pulled away from the wall for cleaning,
service, or any other reason, ensure that the Anti-Tip
Device is properly reengaged when the range is pushed
back against the wall.
To reduce the risk of tipping of the range, the range must be
secured by properly installed anti-tip devices. To check if
the bracket is installed properly.
- Warming drawer : grasp the top rear edge of the Range
and carefully attempt to tilt it forward.
Verify that the anti-tip devices are engaged.
- Storage drawer : Remove drawer and verify leveling leg is

Refer to the installation manual for proper anti-tip bracket installation.
WARNING
• DO NOT touch burners, grates or
interior surfaces of oven.
- Burners, grates may be hot even though they are off.
- Interior surfaces of an oven become hot enough to
cause burns.
• During and after use, do not touch, or
let clothing or other flammable
materials contact burners, grates or
interior surfaces of oven until they
have had sufficient time to cool.
-
Other surfaces of the appliance may become hot
enough to cause burns among these surfaces are
oven vent openings and surfaces near these
openings, oven doors, and windows of oven doors.
WARNING
• DO NOT store items of interest to
children in cabinets above a range or
on the back guard of a range.
- Children climbing on the range to reach items
could be seriously injured.
WARNING
• ALL RANGES CAN TIP
• INJURY TO PERSONS
COULD RESULT
• INSTALL ANTI-TIP DEVICES
PACKED WITH RANGE
• SEE INSTALLATION
• 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.
• Make sure your range is properly adjusted by a qualified
service technician or installer for the type of gas (natural or
LP) that is to be used. Your range can be converted for use
with either type of gas.
• NEVER block the vents (air holes)of the range. They provide
the air inlet and outlet that are necessary for the range to
operate properly with correct combustion. Air openings are
located at the rear of the cooktop, at the top and bottom of the
oven door, and at the bottom of the range under the warming
drawer.

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.

IMPORT TANT SAFETY INSTRUCTIONS ANT 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.

Convection Bake / Roast Mode
Convection bake should be used for cooking
casseroles and roasting meats. Oven should be
preheated for best results when using convection
bake. The convection cooking modes automatically
reduce the oven temperature by 25 °F (14 °C).
The display shows the changed temperature.
• This feature is called auto conversion.
• The range comes with this feature enabled.
• The oven fan runs while convection baking.
If the door is left open for longer than 30 seconds
during baking, the fan stops.
Broil Mode
Broil burner operates during broil mode. 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.
Cooking Guide
Refer to the Owner’s 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.
