Bosch NGT/NGP Cooktop

Carefully wipe the igniters with a cotton swab wet with water, ammonia, or Formula 409®, and gently scrape off soil with a toothpick. Avoid excess water on the igniter, as a damp igniter will prevent the burner from lighting. Remove any remaining lint after cleaning. (Page 15)

No, you should not clean removable cooktop parts in any self-cleaning oven. Always use the mildest cleaner that will do the job with clean, soft cloths, sponges, or paper towels. After cleaning, place all parts in their proper positions before using the cooktop. (Page 14)

Do not try to light any appliance, do not touch any electrical switch, and do not use any phone in your building. Immediately call your gas supplier from a neighbor's phone and follow the gas supplier's instructions. If you cannot reach your gas supplier, call the fire department. (Page 6)

The cooktop comes with a full one-year warranty from the date of installation, covering any part that fails in normal home use — Bosch will pay for all repair labor and replacement parts found to be defective due to materials and workmanship. Service must be provided by a Factory Authorized Service Agency during normal working hours. The warranty does not cover damage from misuse, improper installation, or service by unauthorized agencies. (Page 15)

The 30-inch models have two universal grates that should be positioned with the straight side in the center; they are interchangeable by rotating 180°. The 36-inch models have one side grate, one center grate, and one single grate that must be positioned as illustrated in the manual. All four feet of each grate must be placed into the corresponding dimples in the cooktop, and grates with missing or damaged rubber feet should not be used. (Page 8)

To operate a burner, select the appropriate control knob, push down and turn counter-clockwise to the desired flame size. To turn off, turn the control knob clockwise to the OFF position. The standard burner controls have an infinite number of heat settings with no fixed positions. (Page 9)

If the burner does not light within 4 seconds, turn the burner off immediately. Check to see that the cap is positioned correctly on the burner base and that the igniter is clean and dry. If the burner still fails to ignite after checking these items, refer to the 'Before Calling for Service' section. (Page 10)

Yes, the burners can be ignited manually during a power failure. Turn all burner control knobs to the OFF position first, then hold a match at the ports and turn the control knob to the HI position. Wait until the flame is burning all the way around the burner before adjusting to the desired height. Note that the automatic reignition feature will not work during a power failure. (Page 10)

A yellow flame indicates that further adjustment is required. If the flame is completely or mostly yellow, verify that the regulator is set for the correct fuel type. After adjustment, retest the burner. Note that yellow tips on outer cones are normal for LP gas, while soft blue flames are normal for natural gas. (Page 10)

Clean the burner cap exterior (porcelain enamel) with hot sudsy water, rinsing and drying thoroughly; nonabrasive cleansers like Fantastic or Formula 409 can also be used. For the burner base and underside of the cap (aluminum alloy), use detergent and hot water or abrasive pads like Brillo or S.O.S., then rinse and dry. Do not soak burner caps, and clean clogged ports with a wire or straightened paper clip — never a toothpick that may break off. (Page 14)

Do not try to light any appliance, do not touch any electrical switch, and do not use any phone in your building. Immediately call your gas supplier from a neighbor's phone and follow their instructions. If you cannot reach your gas supplier, call the fire department. (Page 6)

The burner cap has a locator on its underside that 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. Always reassemble the cap so it is seated on the base and aligned with the notch. (Page 8)

Flat, heavy bottom pans provide even heat and stability, and aluminum or copper-bottomed pans conduct heat evenly. Do not use pans that are thin, warped, dented, or ridged as they heat unevenly. The flame should be the same size as the bottom of the pan or smaller — never use small pans with high flame settings. (Page 11)

The cooktop comes with a full one-year warranty from the date of installation or date of occupancy for a new, previously unoccupied dwelling. During this period, any part that fails in normal home use will be repaired or replaced free of charge, with Bosch paying for all repair labor and replacement parts found to be defective due to materials and workmanship. Service must be provided by a Factory Authorized Service Agency during normal working hours. (Page 15)

Before calling for service, verify that the gas shut-off valve is in the ON position and the home gas supply is not shut off. Also ensure the burner caps are properly positioned, the burner ports are not clogged, the igniters are clean and dry, and there is no draft in the room. Additionally, check that the unit is plugged in, properly grounded, and that the circuit breaker has not tripped. (Page 15)
