Sealed BurnersYour 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 CapsThe 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.

30" (76cm) Models have two universal grates. Position the straight side in the center. They are interchangeable by rotating 180°.
36" (91cm) 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 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.
Burner Control KnobsThe standard burner controls have an infinite number of heat settings with no
fixed positions.

firmly.
•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.
English 5
Operation
Normal Operation
(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.
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 FailureIn 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.
Typical Flame CharacteristicsThe 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
English 6
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)
•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 OFF.
•While the flame is ON, there may be bubbling.
•There should be steam and slight quivering of the liquid’s surface while simmering.
•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.
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-tomedium 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.
Proper Cookware Practices
Table 2: Proper Cookware Practices
Practice
a) 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.
b) 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 maintain a boil or pressure (for pressure canners/cookers).
