OPERATION
GAS SURFACE BURNERS
BEFORE USING THE GAS SURFACE BURNERS
Read all instructions before using.
WARNING
CAUTION
• Make sure all burners are in their correct locations and fully assembled
before attempting to operate any burner.
• Never leave the surface burners on unattended. Boilovers may cause
smoke and greasy spillovers that may ignite.
• Do not use aluminum foil to line or cover the cooktop, grates, or any
other part of the cooktop. Doing so may result in carbon monoxide
poisoning, overheating of the cooktop surfaces, or fire.
• Use the proper pan size. Do not use pans that are unstable or that can
be easily tipped. Select cookware with flat bottoms large enough to
cover burner grates.
• To avoid spillovers, make sure the cookware is large enough to contain
the food properly. This will both save cleaning time and prevent
hazardous accumulations of food, since heavy spattering or spillovers
left on the range can ignite.
• Control the top burner flame size so it does not extend beyond the edge
of the cookware. Excessive flame is hazardous.
• Do not operate the burner for an extended period of time without
cookware on the grate. The finish on the grate may discolor or chip
without cookware to absorb the heat.
• Do not attempt to disassemble any burner while another burner is on.
Damage to the product may occur.
• Be sure the burners and grates are cool before you place your hand, a
pot holder or cleaning materials on them.
18
IMPORTANT:
USING THE GAS SURFACE BURNERS
The appearance of the knobs may vary from what are shown below.
Lighting a Surface Burner
NOTE:
1. Select a burner and find its control knob.
2. Push the control knob in and turn it to the IGNITE position. The electric
spark ignition system will make a clicking noise.
• The use of a gas-cooking appliance results in the production of heat and
moisture in the room in which it is installed. Ensure that the kitchen is well
ventilated: keep natural ventilation holes open or install a mechanical
ventilation device (mechanical extractor hood).
• Prolonged intensive use of the appliance may call for additional
ventilation, for example opening of a window, or more effective
ventilation, for example increasing the level of mechanical ventilation
where present.
• When one burner on the left or the right side is turned to IGNITE,
the other 3 burners on the same side will spark. Sparking will
continue as long as the knob remains at IGNITE.

Selecting a Flame Size
Watch the flame, not the control knob, as you reduce heat. Match the flame
size on a gas burner to the cookware being used for fastest heating.
NOTE:
• Never let the flames extend up the sides of the cookware. Flames larger
than the bottom of the cookware will not heat faster and may be
hazardous.
In Case of Power Failure
In case of a power failure, you can light the gas surface burners on your range
with a match. Surface burners in use when an electrical power failure occurs
will continue to operate normally.
1. Using extreme caution, hold a lit match to the burner
2. Push in the control knob, then turn the control knob to the Lo position.
3. Once gas is ignited, turn the control knob to adjust the flame size.
20
USING THE PROPER COOKWARE
Aluminum
Medium-weight cookware is recommended because it heats quickly and
evenly. Most foods brown evenly in an aluminum skillet. Use saucepans with
tight fitting lids when cooking with minimum amounts of water.
Cast-Iron
If heated slowly, most skillets will give satisfactory results.
Stainless Steel
This metal alone has poor heating properties and is usually combined with
copper, aluminum or other metals for improved heat distribution.
Combination metal skillets work satisfactorily if they are used with medium
heat as the manufacturer recommends.
Enamelware
Under some conditions, the enamel of this cookware may melt. Follow
cookware manufacturer’s recommendations for cooking methods.
Glass
There are two types of glass cookware. Those for oven use only and those for
top-of-range cooking.
Heatproof Glass Ceramic
Can be used for either surface or oven cooking. It conducts heat very slowly
and cools very slowly. Check cookware manufacturer’s directions to be sure it
can be used on gas ranges.

21
NOTE:
• The flame should not extend beyond the bottom edge of the cookware.
Oversized cookware that spans two burners should be placed front to
rear, not side to side.
• Use balanced cookware that sits level on the cooktop grate without
rocking. Center the cookware over the burner.
• Use a lid that fits properly. A well-fitting lid helps shorten the cooking
time.
• Match the size of the cookware to the amount of food being cooked to
save energy when heating.
• Do not use stove top grills on the surface burners. Using a stove top grill
on the surface burner will cause incomplete combustion and can result
in exposure to carbon monoxide levels above allowable current
standards. This can be a health hazard.
• If using a wok, use only a flat-bottomed wok with diameter of 14 inches
or less. Make sure that the wok bottom sits flat on the grate.
• Do not use a wok support ring. Placing the ring over the burner or grate
may cause the burner to work improperly, resulting in carbon monoxide
levels above allowable standards. This can be hazardous to your
health.
22
OVEN
BEFORE USING THE OVEN
Read the instructions for each feature and cooking mode in this manual
carefully before using the oven.
• Do not use any type of foil or oven liner to cover the oven bottom. These
items can trap heat or melt, resulting in damage to the product and risk
of shock, smoke or fire. Damage from improper use of these items is not
covered by the product warranty.
• Foil may be used to catch spills by placing a sheet on a lower rack,
several inches below the food. Do not use more foil than necessary and
never entirely cover an oven rack with aluminum foil. Keep foil at least
1-1/2" (3.8 cm) from oven walls to prevent poor heat circulation.
• Do not cover the slotted grid of the 2-piece broiler pan with aluminum
foil. This will catch the grease and could cause fire.
• Do not use plastic wrap or wax paper in the oven.
• Do not place food, water, ice, or any dish or tray directly on the oven
floor, as this will irreversibly damage the enamel surface.
• Do not block, touch or place items around the oven vent during
cooking. Your oven is vented through ducts at the center above the
burner grate. Do not block the oven vent when cooking to allow for
proper air flow.
• In case of power failure, do not use the oven. The oven and broiler
cannot be used during a power outage. If the oven is in use when a
power failure occurs, the oven burner shuts off and cannot be re-lit until
power is restored. Once power is restored, you will need to reset the
oven cooking mode.
• As the oven heats up, the heated air in the oven may cause
condensation to appear on the oven door glass. These water drops are
harmless and will evaporate as the oven continues to heat up.
CAUTION
23
FOOD POISONING HAZARD
• Do not let food sit in oven more than one hour before or after cooking.
Doing so can result in food poisoning or sickness.
• Foods that can easily spoil such as milk, eggs, fish, meat or poultry,
should be chilled in the refrigerator first. Even when chilled, they should
not stand in the oven for more than 1 hour before cooking begins, and
should be removed promptly when finished cooking.
NOTE:
• Because the oven temperature cycles, an oven thermometer placed in
the oven cavity may not show the same set temperature on the oven.
BEFORE USING THE OVEN FOR THE FIRST TIME
Start the oven in BAKE mode at the highest available temperature setting.
Allow oven to run for 1 hour to remove any dust or impurities. There will be a
distinctive odor - this is normal. Ensure your kitchen is well ventilated during
this conditioning period.
OVEN VENT
Areas near the vent may become hot during operation and may cause burns.
Avoid placing plastics near the vent as heat may distort or melt the plastic.
Do not block the vents (air openings) of the range. They provide the air inlet
and outlet that are necessary for the range to keep cool and operate properly
with correct combustion.
It is normal for steam to be visible when cooking foods with high moisture
content.
WARNING
24
OVEN DOOR
To avoid oven door glass breakage:
CAUTION
USING OVEN RACKS
The racks have a turned-up back edge that prevents them from being pulled
out of the oven cavity.
• Do not close the oven door if the racks are not fully inserted into the oven
cavity or if bakeware extends past the front edge of an oven rack.
• Do not set objects on the glass surface of the oven door.
• Do not hit glass surfaces with bakeware or other objects.
• Do not wipe down glass surfaces until the oven has completely cooled.
Removing Racks
Replacing Racks
1. Pull the rack straight out until it
stops.
2. Lift up the front of the rack and
pull it out.
• Replace oven racks before turning the oven on to prevent burns.
• Do not cover the racks with aluminum foil, or any other material, or
place anything on the bottom of the oven. Doing so will result in poor
baking and may damage the oven bottom.
• Only arrange oven racks when the oven is cool.
1. Place the end of the rack on the
support.
2. Tilt the front end up and push the
rack in.
25
Rack Positions
For best cooking results, adjust rack so
food is placed at the center of the
oven. For most foods this will be rack
position #2 or #3. For larger foods like
roasts and turkey, move the rack
position down to #1 or #2 to keep the
food centered in the oven.
When using multiple racks
simultaneously, try to space the food
out around the oven center (rack
position #1 and #3 or #2 and #4 for
two racks).
Broiling performs best with the food
close to the broil burner - typically rack
position #4 or #5.
PREHEATING
Preheating is generally desirable, although not absolutely necessary in all
circumstances. Some foods are more robust and may have acceptable results
without preheating. These foods include large pieces of meat (whole roasts,
hams, or poultry) where the total cooking time is much longer than the time
required to preheat. These foods also include frozen potato products and
frozen processed dinners that, by their nature and design, are more robust to
baking variations. More delicate foods, such breads (including cakes, cookies,
pastries, and pizzas), desserts, soufflés, etc. will likely not have acceptable
results without proper preheating.

BAKE
The Bake mode uses heat from the lower heating element to cook food. This
mode works best with food placed on a single rack. When using this mode to
prepare baked goods such as cakes, cookies and pastries, always preheat the
oven first and place food centrally near the middle or lower racks.
Setting the Bake Mode (Example: Set Bake at 350°F.)
1. Adjust oven rack levels as needed.
2. Turn the thermostat knob to select 350°F. The oven turns on and starts
preheating.
NOTE:
• Once the oven reaches the set temperature, the oven pauses
heating and the oven indicator light turns off temporarily. The oven
heating cycle will automatically resume to maintain the set
temperature, and the oven indicator light will turn on again.
3. Place the food in the oven after preheating.
4. Turn the thermostat knob to the OFF position when cooking is finished,
and remove the food from the oven.
NOTE:
• Baking time and temperature will vary depending on the
characteristics, size, and shape of the baking pan used.
• Check for food doneness at the minimum recipe time.
• Use metal bakeware (with or without a nonstick finish), heatproof glass-
ceramic, ceramic or other bakeware recommended for oven use.
• Dark metal pans or nonstick coatings will cook food faster with more
browning. Insulated bakeware will slightly lengthen the cooking time
for most foods.
28
BROIL
The Broil mode uses intense heat from the upper heating element to sear
foods. This mode works best for tender cuts of meat, fish, and thinly cut
vegetables, and is ideal for toasting, melting cheese, browning and searing
surface. Food should be placed near the upper racks, and should not be
cooked for too long on each side of the food. Preheat the oven for about 5
minutes before placing food in the oven.
Setting the Broil Mode
1. Adjust oven rack levels as needed and place the food in the oven.
2. Turn the thermostat knob to select BROIL. The oven turns on and starts
preheating.
3. Place the food in the oven after preheating for about 5 minutes.
4. Turn the thermostat knob to the OFF position when cooking is finished,
and remove the food from the oven.
NOTE:
• The broil burner is very powerful. Follow recipe directions and monitor
food closely to reduce risk of burning food.
• Always use a broiler pan and grid for excess fat and grease drainage.
This will help to reduce splatter, smoke, and flare-ups.
• Do not use a broiler pan without a grid. Oil can cause a grease fire.
• Do not cover the grid and broiler pan with aluminum foil. Doing so will
cause a fire.

CONVECTION BAKE
The Convection Bake mode uses heat from the lower heating element and hot
air movement from the convection fan to enhance cooking efficiency and
evenness across multiple racks. Always preheat the oven first. Baking times
may be slightly longer for multiple racks than what would be expected for a
single rack.
Setting the Convection Bake Mode
(Example: Set Convection Bake at 350°F.)
1. Adjust oven rack levels as needed.
2. Turn the thermostat knob to select 350°F, and press the Convection Fan
button. The oven turns on and starts preheating.
NOTE:
• Once the oven reaches the set temperature, the oven pauses
heating and the oven indicator light turns off temporarily. The oven
heating cycle will automatically resume to maintain the set
temperature, and the oven indicator light will turn on again.
3. Place the food in the oven after preheating.
4. Press the Convection Fan button and turn the thermostat knob to the OFF
position when cooking is finished, and remove the food from the oven
NOTE:
• The oven fan runs while convection baking.
• Use Convection Bake for faster and more even multiple-rack cooking of
pastries, cookies, muffins, biscuits, and breads of all kinds.
• Place the oven racks in positions suggested in the "Tips and Techniques"
section.
• Bake cookies and biscuits on pans with no sides or very low sides to
allow heated air to circulate around the food. Food baked on pans with
a dark finish will cook faster.
30
TIPS AND TECHNIQUES
BAKE
Baking is cooking with heated air. The lower heating element in the oven is
used to heat the air but no fan is used to circulate the heat.
Follow the recipe or convenience food directions for baking temperature, time
and rack position. Baking time will vary with the temperature of ingredients
and the size, shape and finish of the baking utensil.
• For best results, bake food on a single rack with at least 1" - 1½" (2.5 - 3
cm) space between utensils and oven walls.
• Use one rack when selecting the bake mode.
• Check for doneness at the minimum time.
• Use metal bakeware (with or without a non-stick finish), heatproof glass,
glass-ceramic, pottery or other utensils suitable for the oven.
• When using heatproof glass, reduce temperature by 25°F (15°C) from
recommended temperature.
• Use baking sheets with or without sides or jelly roll pans.
• Dark metal pans or nonstick coatings will cook faster with more browning.
Insulated bakeware will slightly lengthen the cooking time for most foods.
• Do not use aluminum foil or disposable aluminum trays to line any part of
the oven. Foil is an excellent heat insulator and heat will be trapped
beneath it. This will alter the cooking performance and can damage the
finish of the oven.
BROIL
The Broil mode uses intense heat from the upper heating element to sear
foods. The size, weight, thickness, starting temperature, and your preference
of doneness will affect broiling times.
• For best results when broiling, use a broiler pan and grid designed for
broiling.
• For proper draining, do not cover the grid with foil. The bottom of the pan
may be lined with aluminum foil for easier cleaning.
• Trim excess fat to reduce spattering. Slit the remaining fat on the edges to
avoid curling.
• Preheat the oven for about 5 minutes before placing food in the oven.
31
CONVECTION BAKE
The convection fan increases air movement and circulates heat within the
oven to improve heat distribution on multiple racks and enhance cooking
evenness while cooking with single or multiple racks. Reduce recipe baking
temperatures by 25°F (15°C). Cooking times may be slightly longer for multiple
racks than what would be expected for a single rack.
• For best results, foods should be cooked uncovered, in low-sided pans t o
take advantage of the forced air circulation. Use shiny aluminum pans fo r
best results unless otherwise specified.
• Heatproof glass or ceramic can be used. Reduce temperature by anothe r
25°F (15°C) when using heatproof glass dishes for a total reduction o f
50°F (30°C).
• Dark metal pans may be used. Note that food may brown faster whe n
using dark metal bakeware.
• The number of racks used is determined by the height of the food to be
cooked.
• Baked items, for the most part, cook extremely well in convection. Don’ t
try to convert recipes such as custards, quiches, pumpkin pie, o r
cheesecakes, which do not benefit from the convection-heating process.
Use the regular Bake mode for these foods.
• Multiple rack cooking for oven meals is
mostly done on rack positions 1, 2, 3,
and 4. All four racks can be used for
cookies, biscuits and appetizers.
- 2 Rack baking: Use positions 2 and
4 or 1 and 3.
- 3 rack baking: Use positions 1, 3
and 5 or 2, 3 and 4.
- When baking four cake layers at
the same time, stagger pans so
that one pan is not directly above
another. For best results, place
cakes on front of one rack and
back of another rack (See graphic
at right). Allow 1" - 1 ½" (2.5 – 3 cm)
air space around pans.
• Converting your own recipe can be easy. Choose a recipe that will work
well in convection.
• Reduce the temperature and cooking time if necessary. It may take som e
trial and error to achieve a perfect result. Keep track of your technique fo r
the next time you want to prepare the recipe using convection.

RANGE CARE AND MAINTENANCE
CLEANING
IMPORTANT: Before cleaning, make sure all controls are off and the oven and
cooktop are cool. Always follow label instructions on cleaning products. Soap,
water and a soft cloth or sponge are suggested first unless otherwise noted.
Do not use abrasive cleaning products.
NOTE:
• Do not clean the oven door gasket. The material of the gasket cannot
withstand abrasion. It is essential for the gasket to remain intact. If you
notice it becoming worn or frayed, replace it.
EXTERIOR PORCELAIN ENAMEL SURFACES
• Food spills containing acids, such as vinegar and tomato, should be
cleaned as soon as the entire appliance is cool. These spills may affect the
finish.
Cleaning Method:
• Glass cleaner, mild liquid cleaner or nonabrasive scrubbing pad: Gently
clean around the model and serial number plate because scrubbing may
remove numbers.
EXTERIOR STAINLESS STEEL
• Rub in direction of grain to avoid damaging.
Cleaning Methods:
• Liquid detergent or all-purpose cleaner: Rinse well with clean water and
dry with soft, lint-free cloth.
• Stainless Steel Cleaner and Polish. Vinegar for hard water spots.
NOTE:
• Do not use soap-filled scouring pads, abrasive cleaners, Cooktop
Polishing Cream, steel-wool pads, gritty washcloths or some paper
towels. Damage may occur, even with one-time or limited use.
33
OVEN DOOR EXTERIOR
Cleaning Method:
• Glass cleaner and paper towels or nonabrasive plastic scrubbing pad:
Apply glass cleaner to soft cloth or sponge, not directly on panel.
PORCELAIN-COATED GRATES AND CAPS
• Clean as soon as cooktop, grates and caps are cool.
• Food spills containing acids, such as vinegar and tomato, should be
cleaned as soon as the cooktop grates and caps are cool. These spills
may affect the finish.
• To avoid chipping, do not bang grates and caps against each other or
hard surfaces such as cast iron cookware.
• Do not reassemble caps on burners while wet.
Cleaning Method:
• Nonabrasive plastic scrubbing pad and mildly abrasive cleanser.
BURNER BASE/SPREADER
Cleaning Method:
• Wash the burner base/spreader frequently with boiling water and
detergent to remove any deposits which could block the flame outlet.
• Before reinstalling, dry the burner base/spreader thoroughly so the
burner will ignite properly.
COOKTOP CONTROL KNOBS
• Pull knobs straight away from control panel to remove.
• When replacing knobs, make sure knobs are in the OFF position.
