WARNING — TO REDUCE THE
RISK OF BURN INJURIES DURING

!

COOKTOP USE, OBSERVE THE
FOLLOWING:

• When using the cooktop: DO NOT TOUCH THE
BURNER GRATES OR THE IMMEDIATE SUR­ROUNDING AREA.

• Use only dry potholders; moist or damp potholders
on hot surfaces may cause burns from steam.

• Never leave the cooktop unattended when in use.
Boilovers cause smoking, and greasy spillovers may
ignite. A spill on a burner can smother all or part of
the flame or hinder spark ignition. If a boilover
occurs, turn off burner and check operation. If
burner is operating normally, turn it back on.

• During cooking, set the burner control so that the
flame heats only the bottom of the pan and does
not extend beyond the bottom of the pan.

• Take care that drafts like those from fans or forced air
vents do not blow flammable material toward the

flames or push the flames so that they extend
beyond the edges of the pan.

• Always position handles of utensils inward so they
do not extend over adjacent work areas, burners, or the
edge of the cooktop.

• Wear proper apparel. Loose fitting garments or
hanging sleeves should never be worn while cooking.

• In the event that personal clothing catches fire, DROP
AND ROLL IMMEDIATELY to extinguish flames.

• Never let clothing, potholders, or other flam­mable materials come in contact with hot burn­ers or hot burner grates.

• Use only certain types of glass, heatproof glass­ceramic, ceramic, earthenware, or other glazed
utensils that are suitable for cooktop use.

• Do not clean the cooktop while it is still hot. Some
cleaners produce noxious fumes when applied to a hot
surface.

• Never use the cooktop to warm or heat a room.

• Children or pets should not be left alone or

unattended in an area where appliances are in
use. They should never be allowed to sit or stand on any

part of the appliance.

• CAUTION: Do not store items of interest to

children above or at the back of the cooktop .

• Do not store flammable materials on or near the
cooktop.

• CAUTION: Do not allow aluminum foil, plastic,
paper or cloth to come in contact with a hot
burner or grate. Do not allow pans to boil dry.

COOKTOP OPERATION

The following pages explain how each feature on the
gas cooktop works and how to get the best cooking
results.
Follow these hints when cooking on the cooktop:

• Use proper cookware. (See Page 6.)

• Center the pan over the burner before turning the

burner on.

• Refer to the Cooking Chart on Page 7 for suggested

flame settings.

Sealed Burners

Your new cooktop has sealed gas burners. There are
no burner parts under the cooktop to clean, disassemble
or adjust. Your cooktop has two different burner cap
sizes, large and medium. Match the pan to the size burner.

Burner Caps

Porcelain

Enamel Burner Cap

Burner Grates

The position of each double grate is labeled on the

underside edge of the grate as shown in the figure below.

Single

(36"

models

only)

SideUniversal

(30" models only)

30" Models have two universal grates. Position the

straight side in the center. They are interchangeable by
rotating 180°.

36" Models have one side grate, one center grate and

one single grate. Position the grates on the cooktop as
illustrated above.

WARNING:To prevent flare-ups all
grates must be properly positioned on the
cooktop whenever the cooktop is in use.
Each of the four feet must be placed into
the corresponding dimples in the cooktop.
See illustration on Page 8. Do not use a grate
if the rubber feet are missing or damaged.

Center

Notch

Burner Base

The burner cap is porcelainized steel. On the under­side of the cap is one locator which must fit into the
corresponding notch on the burner base. If the burner
cap is not placed correctly, the burner may not light or the
flame may not burn completely or correctly.

WARNING: To prevent flare-ups do not
use the cooktop without all burner caps

!

and all burner grates properly positioned.

STANDARD BURNER CONTROL

PAGE 4

COOKTOP OPERATION

Burner Control Knobs (continued)

The standard burner controls have an infinite number

of heat settings with no fixed positions.

To operate: Select the appropriate control knob, push
down and turn counterclockwise to the desired flame
size. Turn OFF by turning the control knob clockwise to
OFF.

A rubber grommet is located under each control knob.

To remove knob and grommet: With burner in
the OFF position, gently lift knob up and off. Gently pull
grommet toward center and lift out.

WARNING: To avoid electric shock, do not

!

reach through opening into rough-in box.

To replace grommet and knob: Replace grommet by
placing center groove around cooktop. The rubber grom­met should be firmly attached around the cooktop open­ing. Place the control knob indicator line at the OFF
position; press down firmly.

Electronic Ignition/Reignition

The cooktop uses electronic igniters to light the
burners. There is no pilot light. Each burner has its own
igniter. If a burner flame blows out during use, the burner
will automatically reignite.

The ignitor should be clean and dry for proper opera-

tion.

• Avoid getting water or food on the igniter.

• If the igniter is wet or soiled, it may spark without
igniting the burner, or even spark continuously when
a flame is present.

Note: If the burner does not light within 4 seconds,

turn the burner off. Check to see that the cap is posi­tioned correctly on the burner base and the igniter is
clean and dry. If a burner still fails to ignite, see Before
Calling for Service on Page 10.

Typical Flame Characteristics

The burner flame should be blue in color and stable
with no yellow tips, excessive noise or fluttering. It should
burn completely around the burner cap.

Foreign particles in the gas line may cause an orange
flame during initial use. This should disappear with use.
Check burner cap to make sure port holes are not
obstructed. If the ports are clogged, see Before Calling for
Service on page 10.

Note: An audible “pop” may be heard when the
burner is turned off manually. The “popping” may be
louder with LP gas than with natural gas. This is normal.

CAUTION: All igniters spark when any single burner is
turned ON or the reignition system is activated. Do not
touch any of the burners when the cooktop is in use.

Power Failure

In the event of a power failure, the burners can be
ignited manually.

If the cooktop is being used when a power failure
occurs, turn all the burner control knobs to the OFF
position. The burners can then be ignited manually by
holding a match at the ports and turning the control knob
to the HI position. Wait until the flame is burning all the
way around the burner before adjusting the flame to the
desired height.

CAUTION: The reignition feature will not work in
the event of a power failure.

PAGE 5

PROPER COOKWARE

Cookware Characteristics

• Aluminum or copper bottomed pans conduct heat evenly.

• Steel pans, if not combined with other metals, may cook unevenly.

• Cast-iron cookware absorbs heat slowly and cooks more evenly at low-to-medium settings.

• Flat, heavy bottom pans provide even heat and stability.

DO NOT USE pans that are thin, warped, dented or ridged as they heat unevenly.

Match Pan Diameter to Flame Size

– The flame should be the same size as the bottom

of the pan or smaller. Do not use small pans with
high flame settings as the flames can lick up the
sides of the pan.

– Oversize pans that span two burners are placed

front to rear, not side to side.

Use Balanced Pans

– Pans must sit level on the cooktop grate without

rocking.

– Center pan over burner.

Use a Lid That Fits Properly

– A well-fitting lid helps shorten the cooking time.

Pans that span 2 burners, i.e. griddles, roasters and fish poachers, may be used when placed front to
back. Adjust flame equally to cook evenly. Use the Bosch accessory griddle on your Bosch Cooktop. To
order, call the 800 number listed below.

Use a wok with a flat bottom. If using a round bottomed wok, use the Bosch accessory support wok
ring. To order call the 800 number listed below.

For simmering stews and soups, or melting chocolate, use the Bosch simmer plate accessory. The
simmer plate distributes the heat evenly and gently. The simmer plate is supplied with NGP models only,
but is available separately for the NGT. Follow use and care instructions provided with the simmer plate.

Canners and pressure cookers must meet the same requirements as described above.

• After bringing contents to a boil, use lowest heat setting possible to maintain a boil or pressure (for
pressure canners/cookers).

PROBLEM SOLVER

BEFORE CALLING FOR SERVICE

IF BURNERS DO NOT IGNITE PROPERLY, CHECK FOR THE FOLLOWING:

• Make sure that the gas shut-off valve is in the
ON position and the gas supply to the house
is not shut off.

• Make sure the burner caps are properly
positioned and the burner ports are not
clogged. Clear ports with a wire or
straightened paper clip if clogged.

• Make sure the igniters are clean and dry.

• Make sure that there is no draft in the room.

• Check the power supply. It should be properly
grounded with the correct polarity. Make sure
the unit is plugged in and the circuit breaker is
not tripped.

• When the electrical power connection has
been activated at the first power up or re­connected after an outage, the igniters may
spark once or twice even though all burner
knobs are in the off position.
