Grates And Burner Caps; Sealed Burners - Bosch NHT 72 Series Use And Care Manual

Grates and Burner Caps
The top surface of the grates and the burner caps
are covered with a porcelain enamel coating. This
coating not only serves to protect the grates and
burner caps from oxidation, but also provides
ferrous components an attractive finish.
The porcelain enamel coating on the burners and
grates undergo extreme thermal and mechanical
conditions; far more severe than experienced by
any other porcelain enamel surface in your kitchen.
This means that over time, due to these severe
conditions, the porcelain enamel coating of these
components will inevitably undergo a change in
appearance. This is in addition to any damage they
may receive from the utensils that may be used on
them. Special attention to the care and cleaning of
the grates and burner caps will slow the changes in
appearance, but will not eliminate them. See the
Care and Cleaning section of this manual for
recommendations for maintaining the appearance
of your cook-top.
Sealed Burners
The cook-top has sealed gas burners designed to
spread the heat evenly across the bottom of your
cooking utensils. Each burner is equipped with a
spark igniter to light the burner and each burner
incorporates auto-reignition in case a flame is
blown out. The burners on the Bosch cook-tops
have been set at the factory for use in Natural Gas.
The cook-top can be converted for use on
LP/Propane, but such a conversion should only be
performed by a qualified service technician.
LP/Propane conversion kits can be ordered from
your dealer
The Bosch gas cook-top comes in two basic sizes:
• The 30 inch, 4 burner, models:
• NHT 722 AUC
• NHT 725 AUC
NHT 726 AUC
have four sealed burners: two large burners
rated at 12,500 BTU/Hr maximum input and
two medium burners rated at 6,000 BTUPHr
maximum input. The two large burners are
located at the front of the cook-top, while the
two medium burners are located at the rear.
The 36 inch, 5 burner, models:
• NHT 922 AUC
• NHT 925 AUC
• NHT 926 AUC
have five sealed burners: two large burners
rated at 12,500 BTU/Hr maximum input and
three medium burners rated at 6,000 BTU/Hr
maximum input. The two large burners are
located at the front of the cook-top, while the
three medium burners are located at the rear.
See Figure 1 on page 6.
The large burners are intended to be used for
cooking large quantities of food, deep frying
and/or cooking with large diameter pots or pans.
The medium burners are to be used for simmering,
for cooking smaller quantities of food, or when
using smaller diameter pots or pans.
The burners used are of the sealed type, meaning
that the bottom of the burners, where they meet the
cook-top surface, are provided with gaskets (seals)
to prevent any spilled liquid from entering the
body of the cook-top. In this way any spilled
liquids are kept out of the cook-top and on the
surface for easy cleaning.
