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

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.

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)

Universal

Side

Center

(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.

STANDARD BURNER CONTROL

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: Toavoidelectricshock,donot 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.

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 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.

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).
