extinguish flames.
• Never let clothing, potholders, or other flammable materials come in contact
with hot burners or hot burner grates.
• Do not clean the cooktop while it is still hot. Some cleaners produce noxious
fumes when applied to a hot surface.
• Smother flames from food fires other than grease fires with baking soda.
Never use water on cooking fires.
• 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.
• Have the cooktop installed and grounded by a qualified technician.
• Do not repair or replace any part of the appliance unless specifically recom-
mended in this manual. All other servicing should be referred to a qualified
technician.
• Do not use aluminum foil to line any part of the cooktop.
If the cooktop is near a window, be certain that curtains or any other window
covering do not blow over or near the burners; they could catch on fire.
When using the cooktop: Do not touch the burner grates or the immediate sur-
rounding 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.
Always position handles of utensils inward so they do not extend over adja-
cent work areas, burners, or the edge of the cooktop.
Wear proper apparel. Loose fitting garments or hanging sleeves should never
be worn while cooking.
Use only certain types of glass, heatproof glass, ceramic, earthenware, or
other glazed utensils that are suitable for cooktop use.
Leave the hood ventilator on when flambeing food.
• Smother flames from a grease fire with a close-fitting lid, cookie sheet, or
other metal tray, then turn off the gas burner. Be careful to prevent burns. If
the flames do not go out immediately, evacuate and call the fire department.
• Do not use water, including wet dishcloths or towels on grease fires. A violent
steam explosion may result.
• Never pick up a flaming pan. You may be burned.

Installation and service must be performed by a qualified installer,
authorized service agency or the gas supplier.
Gas Cooking Safety
• 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 flam-
mable material toward the flames or push the flames so that they extend
beyond the edges of the pan.
• Have the cooktop installed and grounded by a qualified technician. Have the
installer show you where the gas shut-off valve is located.
• For proper lighting and performance of burners, keep igniters clean and dry.
• In the event that a burner goes out and gas escapes, open a window or a
door. Wait at least 5 minutes before using the cooktop.
• Do not obstruct the flow of combustion and ventilation air.
California Proposition 65
WARNING: Burning gas cooking fuel generates some by-products
which are on the list of substances which are known by the State of
California to cause cancer or reproductive harm. To minimize exposure
to these substances, always operate this unit according to the instruc-
tions contained in this booklet and provide good ventilation.

Sealed Burners
Burner Caps
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.
The burner cap is porcelainized steel. On the underside of the cap is one Iocator
which must fit into the corresponding notch on the burner base. tf the burner cap
is not placed correctly, the burner may not light or the flame may not burn com-
pletely or correctly.

WARNING: To prevent flare-ups do not use the cooktop without all
burner caps and all burner grates properly positioned.
Burner Grates The position of each double grate is labeled on the underside edge of the grate as
shown in the figure below.

Burner Control Knobs
WARNING: To prevent flare-ups all grates must be properly posi-
tioned on the cooktop whenever the cooktop is in use. Each of the four
feet must be placed into the corresponding dimples in the cooktop. Do
not use a grate if the rubber feet are missing or damaged.
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 counter-
clockwise to the desired flame size. Turn OFF by turning the control knob clock-
wise 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 cook-
top opening. Place the control knob indicator line at the OFF position; press down
firmly.
Using the Cooktop
Before Using the Cooktop •
for the First Time Remove all packing materials and literature from the cooktop surface.
While cool, wipe with a clean, damp sponge and dry.
There may be a slight odor during the first several uses; this is normal and will
disappear.
Optimum cooking results depend on the proper cookware being selected and
used. (See Proper Cookware.)
Read all safety precautions and Use and Care Manual information prior to
operating.

Operation
Normal Operation
(Electronic Ignition/Reignition)
In the Event of a Power Failure
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.
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.
The ignitor should be clean and dry for proper operation.
• 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.
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 con-
trol knobs to the OFF position. The burners can then be ignited manually by hold-
ing 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.
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.
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow, verify that the regulator is set for the
correct fuel. After adjustment, retest.
Some yellow streaking is normal during the initial start-up. Allow unit to operate
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.
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.

Getting the Most Out Of Your Cooktop
Cooking Techniques
(For Best Results)
Proper Cookware
Cookware Characteristics
Proper Cookware Practices
• Bring food to a boil; stir well to be sure all the food is boiling, then cover and
reduce the setting to the XLO zone.
• Use a lid to keep a more constant cooking temperature.
• Use a higher XLO setting if the pan is uncovered.
• Check the food occasionally to see if the control knob should be turned to a
lower or higher setting.
• If the control knob is set too low to maintain simmer, bring the food back to a
boil before setting a higher simmer setting.
• It is normal to stir food occasionally.
• Simmer bubbles may not be seen when the flame has cycled OFE
• While the flame is ON, there may be bubbling.
• There should be steam and slight quivering of the liquid's surface while sim-
mering.
• Use proper cookware. (See section Proper Cookware below.)
• Center the pan over the burner before turning the burner on.
• Refer to the Cooking Chart below for suggested flame settings.
• 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.
Table 2: Proper Cookware Practices
a)
b)
Practice
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.
English 7

Table 2: Proper Cookware Practices
Practice
c) 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 number listed on the
back cover.
Use a Wok with a flat bottom. If using a round bottomed wok, use the Bosch
accessory support wok ring. To order call the number listed on the back cover.
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 main-
tain a boil or pressure (for pressure canners/cookers).
