Using Electric Ignition
The surface burners are lighted by electric
ignition, eliminating the need for standing pilot
lights with constantly burning flames.
All the igniters make clicking sounds and
spark even when only a single burner is being
turned on. Do not touch any of the burners
when the igniters are clicking.

In case of a power outage, the surface burners
on the cooktop can be lit with a match. Hold a
lighted match to the burner, then turn the knob to
the HIGH position. Use extreme caution when
lighting burners this way.
Surface burners in use when an electrical power
failure occurs will continue to operate normally.

The burners on this cooktop automatically
relight if the flame goes out. All burner igniters
spark while a burner is relighting.
Lighting a Burner
Push the control knob in and turn it
counterclockwise to the desired position from
HIGH to LO.
After the burner ignites, turn the knob in
either direction to adjust the flame size.
To turn a burner off, turn the knob clockwise,
as far as it will go, to the OFF position.
The right rear burner is best for smaller pans
and cooking operations that require carefully
controlled simmering conditions. The center
and two left burners are best for general

cooking. The front right burner is the high-power
burner for larger pans and fast boiling.
WARNING: Be sure the burners and grates are
cool before you place your hand, a pot holder,
cleaning cloths, or other materials on them.
Caution: Do not operate a burner for an
extended period of time without cookware on the
grate. The finish on the grate may chip without
cookware to absorb the heat.
Selecting Flame Size
Watch the flame, not the knob, as you reduce
the heat.
The flame size on a gas burner should match
the cookware you are using.
For safe handling of cookware, never let the
flame extend up the sides of the cookware.
Any flame larger than the bottom of the
cookware is wasted and only serves to heat the
handle.
GEA00262
Selecting 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 for
cooking with minimum amounts of water.
Cast Iron: If heated slowly, most skillets will give
satisfactory results.
Enamelware: Under some conditions, the
enamel of some 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 surface
cooking (saucepans, coffee pots, and teapots).
Glass conducts heat very slowly.
Heatproof Glass - Ceramic: This can be used
for either surface or oven cooking. It conducts
heat very slowly and cools very slowly. Check
the cookware manufacturer’s directions to be
sure it can be used on gas cooktops.
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
generally work satisfactorily if they are used at
medium heat as the manufacturer recommends.
– 3 –
Using Woks
WARNING: Do not use woks that have
support rings. Use of these types of woks, with
or without the ring in place, can be dangerous.
Placing the ring over the burner grate may cause
the burner to work improperly, resulting in carbon
monoxide levels above allowable current
standards. This could be dangerous to the
customer’s health. Do not try to use such woks
without the ring. Serious burns may result if the
wok is tipped over.
We recommend using only a flat-bottomed wok,
available at local retail stores.
Using Stovetop Grills
WARNING: Do not use stovetop grills on your
sealed gas burners. Using the stovetop grill on
the sealed gas burner will cause incomplete
combustion and can result in exposure to carbon
monoxide levels above allowable current
standards. This can be hazardous to the
customer’s health.

Downdraft Vent Features and Controls
GEA00265
Throughout this manual, features and appearances may vary from the customer’s model.
Raising or Lowering the Vent
WARNING: Be careful when raising or lowering the
vent. Be sure pots, pot handles, and other objects
are clear of the vent cover and cannot be struck or
tipped by the vent being raised. Keep hands and
fingers away from all vent parts.
Note: The vent fan will only operate in the fully
extended position.
To raise the vent, turn the VENT knob to the
RAISE/LOWER position. The vent will rise to the
fully extended position. There is no intermediate
position.
To lower the vent, turn the VENT knob again to
the RAISE/LOWER position. The vent will then
descend.
GEA00267
Operating the Vent System
Turn the FAN knob to the HIGH position to turn it
on. If you continue turning the FAN knob, you can
select a fan speed between HIGH and LO.
The FAN knob does not have to be turned to OFF
before the vent is lowered. The fan will
automatically turn off when the VENT LOWER
position is selected.
If the fan was not turned OFF when the vent was
lowered, it will automatically come on at the
previously selected speed when the vent is fully
raised.

Care and Cleaning
Proper care and cleaning are important for efficient and
satisfactory service.
WARNING: Before cleaning, be sure all burners are
OFF and disconnect electrical power to the cooktop at
the fuse box, circuit breaker panel, or cooktop power
plug, located inside the cabinets beneath the cooktop.
Cleaning Glass Cooktop
WARNING: Do not cook on, or clean, a broken or
cracked cooktop. Cleaning solutions and spillovers
penetrating the cooktop can create a risk of electric
shock.
Caution: Do not use abrasive materials such as metal
pads, cleansing powder,or scouring pads—they may
scratch the surface. Do not use harsh chemicals such as
bleach or chemical oven cleaners.
GEA00251
GEA00252
To keep the cooktop looking its best, wipe up any spills
as they occur. This will keep them from burning on and
becoming more difficult to remove. As soon as the
cooktop is cool, wash the glass surface with a cloth
moistened with warm, soapy water. Rinse the surface
with clean water, and dry it with a soft cloth. You can use
any liquid household detergent.
Cleaning Grease Filters
The efficiency of the downdraft depends on a clean filter.
Frequency of cleaning depends on the type of cooking
you do. Grease filters should be cleaned at least once a
month. Never operate the downdraft without the filters in
place.
To remove: Lift up and pull the bottom out. Remove the
left filter first, then slide the right filter to the left and
remove it.
To clean: Soak, then agitate in a hot detergent solution.
Light brushing may be used. Rinse, shake, and remove
moisture before replacing. Filters may be cleaned by
placing them in a dishwasher, although some slight color
fading may occur after several washings.
GEA00253
With careful handling, the filter will last for years. If
replacement becomes necessary, order the part from
your dealer.

WARNING: Do not operate the burner without all burner
parts in place.
• Turn all controls OFF before removing burner parts.
The burner grates, caps, and burner heads can be lifted
off, making them easy to clean.
Cleaning Burner Heads
Note: Before removing the burner heads and caps,
remember their sizes and locations. Replace them in the
same locations after cleaning.
For proper ignition, make sure the small hole in the
section that fits over the electrode is kept open. A
sewing needle or wire twist-tie works well to unclog it.
The slits in the burner heads of your cooktop must be
kept clean at all times for an even, unhampered flame.
You should clean the surface burners routinely,
especially after bad spillovers, which could clog these
openings. To remove burned-on food, soak the burner
heads in a solution of mild liquid detergent and hot water
for 20 to 30 minutes. For more stubborn soil, use a
toothbrush.

Before putting the burner head back, shake out excess
water and then dry it thoroughly by setting it in a warm
oven for 30 minutes. Replace the burner heads and
caps. Make sure the heads and caps are replaced in the
correct locations. There are 2 or 3 medium, 1 large, and
1 small head and cap.
Cleaning Burner Caps
Lift off when cool. Wash burner caps in hot, soapy water
and rinse with clean water. You may scour with a plastic
scouring pad to remove burned-on food particles. Dry
them in a warm oven or with a cloth — don’t reassemble
them wet.
Make sure that caps are replaced on the correct size
burner. There are 2 or 3 medium, one large, and one
small head and cap.

GEA00237
Cleaning Burner Grates
Cast-iron burner grates should be washed regularly and,
of course, after spillovers. Wash them in hot, soapy
water and rinse with clean water. Dry the grates with a
cloth—don’t put them back on the cooktop wet. When
replacing the grates, be sure they’re positioned securely
over the burners.
To get rid of burned-on food, place the grates in a
covered container or plastic bag. Add 1/4 cup ammonia
and let them soak for 30 minutes. Wash, rinse well, and
dry.
To prevent rusting, apply a light coat of cooking oil on
the bottom of the grates.
Caution: Do not operate a burner for an extended
period of time without cookware on the grate. The finish
on the grate may chip without cookware to absorb the
heat.
Note: Although they’re durable, the grates will gradually
lose their shine, regardless of the best care you can give
them. This is due to their continual exposure to high
temperatures.
Cleaning Stainless Steel Surfaces
Caution: Do not use a steel wool pad on stainless steel;
it will scratch the surface.
Some models have stainless steel surfaces. Clean with
hot, soapy water. Rinse and dry. If food soil remains, try
a general kitchen cleaner such as Fantastik
Green®, or Formula 409®.
For hard-to-clean soil, use a standard stainless steel
cleaner, such as Bon-Ami
®
or Cameo®. Soils can be
soaked for several hours with wet towels. Apply cleaner
with a damp sponge, rinse thoroughly, and dry. Always
scrub lightly in the direction of the grain.
After cleaning, use a stainless steel polish such as
Stainless Steel Magic
®
, Revere Copper and Stainless
Steel Cleaner®, or Wenol All Purpose Metal Polish®.
Follow the product instructions for cleaning the stainless
steel surface.
