NES Cooktop Use and Care Manual
IMPORTANT SAFETY INSTRUCTIONS
Read all instructions before using your cooktop
! !
Save These Instructions
• Use only dry potholders. Moist or damp pot
holders on hot surfaces may cause burns from
steam. Do not use a towel or other bulky cloth in
place of potholders. Do not let potholders touch
hot cooking areas.
• This appliance is equipped with one or more
surface units of different sizes. Always use utensils
that have flat bottoms and that are large enough
to cover the whole cooking area. The use of a
utensil smaller than the size of the cooking area
will expose a portion of the heated area to direct
contact with the user which could result in burns.
Proper relationship of utensil to burner will also
improve efficiency.
• Turn handles of utensils inward so that they do
not extend over adjacent work areas, cooking
areas, or the edge of the cooktop. This will help
prevent hot food spills, risk of burns and ignition
of flammable materials, and preventing access by
children.
• The cooktop is for cooking. Never use it to warm
or heat a room.
Be sure your appliance is properly installed
and grounded by a qualified servicer in
accordance with the Installation
Instructions provided with the cooktop.
Do not repair or replace any part of the
appliance unless specifically recommended
in this manual.
All other servicing should
be referred to a qualified servicer.
• Always use cookware and utensils appropriate for
the type and amount of food being prepared.
• Do not place any hot cookware on the control
panel area.
• Use high heat settings on the cooktop only when
necessary. Use low to medium settings to heat oil
slowly.
• Never move a pan of hot oil, especially a deep fat
fryer. Wait until it is cool.
• Never leave the cooktop unattended when using
high heat settings. Boilovers can cause smoke and
possibly damage the cooktop.
• Hold the handle of the pan to prevent movement
of the utensil when stirring or turning food.
• Other than the use of metal pans,only certain types
of glass, heatproof glass ceramic, ceramic,
earthenware, or other glazed utensils are suitable
for cooktop use.These types of utensils may break
with sudden temperature changes.Use only on low
or medium heat settings according to the utensil
manufacturer’s directions.
• Clean the cooktop with caution. If the soil must
be removed while the cooktop is hot, clean the
hot top with the metal razor blade scraper only.
Do not use a wet sponge or cloth while it is hot.
Some cleaners produce noxious fumes if applied
to a hot surface.
• Clean the ventilation system above or behind the
cooktop frequently so that grease from the
cooking vapors does not accumulate on the filters,
fan, intake, or hood.
• For people who wear electronic implants such
as a pacemaker or insulin pump, it is possible that
some implants may be affected by magnetic fields.
You should not carry the control knob (mTwisT
dial) in your pockets. The control knob is highly
magnetic and persons wearing electronic implants
should keep the control knob at least four inches
from the implant.

Retained Heat
The glass cooking surface retains heat and stays hot
after the element(s) have been turned off. The retained
heat may be used to hold foods at serving temperatures
for a short time.
General Operation of Cooktop
The cooktop uses touch pads and a magnetic dial to
operate the cooktop.When touching the glass of a touch
pad, such as an element or function pad, use the flat
part of the finger and touch the center of the pad. A
beep will sound when touching any of these pads.
mTwisT Dial
The cooktop uses a mTwisT magnetic dial to select
the desired heat setting. The mTwisT dial is held onto
the cooktop by a strong magnet and automatically
positions itself in the center of the dial location when
placed on the cooktop.
Note: If the dial is removed from the cooktop when
in use, all elements will be turned off. The cooktop is
locked and the Panel Lock light comes on. (See Setting
Panel Lock on Page 6.)
Element‘ON’ Indicator Light
The area above the element touch pad being used
will show the cook setting when the element is on.
When the element is turned off, the hot surface
indicator comes on in this area. (See Hot Surface
Indicator Light below).
Hot Surface Indicator Light
Each element features a hot indicator light to show
when the cooking surface is too hot to touch. A
letter Hwill appear above the element touch pad.
The light remains on until the cooking area has cooled to a
safe-to-touch temperature.
If a hot surface light is on, use caution when working or
cleaning around the cooktop as the cooktop is still hot.

NES Cooktop Use and Care Manual Cooktop Operating Instructions
The Elements / Setting the Controls
PAGE 5
Radiant Elements
Bosch UltraSpeedTM radiant elements use a wire
ribbon located under the ceramic glass surface to
provide the heat for cooking.These radiant elements
will cycle on and off by design (see Temperature
Limiters, below.) There are 9 heat setting positions
from 9 (high) to 1 (low) and a special setting for keep
warm.
Dual Element
The dual element consists of two radiant ribbon
elements within the same heating area. Either the small
inner element or both the inner and outer elements
may be selected for use, depending on the size of
cookware. (See page 7.)
Temperature Limiters
Each UltraSpeed heating element has its own sensor
to protect the glass cooking surface from extreme
high temperatures. The limiters will operate
automatically by cycling the element on and off
regardless of the cook setting.
Although cycling is normal, any one of the following
conditions can activate the limiter and cause it to
cycle on and off more than usual:
• The base of the pan is not making full contact
with the heating surface (due to a warped or
uneven base).
• The pan is too small for the size of the element.
• The pan has boiled dry.
• The material or shape of the pan is slow to
transfer the heat.

Keep dish covered to keep foods hot.
Choose pans and cookware that may be safely used on a
hot surface. Example: Use CorningWare® "Safe for
Rangetop" rather than Pyrex® which is not recommended
for cooktop use.
Use a trivet or steamer inside a pan when necessary to
raise food off bottom of pan.

NES Cooktop Use and Care Manual
Cookware Characteristics
The choice of pans directly affects the cooking speed
and uniformity. For best results select pans with the
following features:
1. Flat Bases - When a pan is hot, the base (pan
bottom) should rest evenly on the surface without
wobbling (rocking). Flat, medium to heavy-weight
pans are best.
To test the flatness of your pans
Turn the pan upside down on the countertop and place
a ruler flat against the bottom of the pan. The bottom
of the pan and the straight edge of the ruler should be
flush against each other.
Another simple test to determine even heat
distribution across the cookware bottom is to place
1” of water in the pan. Bring the water to a boil and
observe the location of the bubbles as the water starts
to boil. Good, flat cookware will have an even
distribution of bubbles over the bottom surface area.
2. Diameter – The base of the pan should cover or
match the diameter of the element being used.
Pans may overhang the element area by 1" all
around.
3.Tight Fitting Lid – A lid shortens cooking time by
holding the heat inside the pan.
Specialty pans
Specialty pans, such as griddles, roasters, pressure
cookers, woks, water bath canners and pressure
canners must have the same features as described
above. Use only a flat-bottom wok. Never place a
support ring, such as a wok ring or trivet, on the
cooking surface.

Cooktop Operating Instructions
Using Proper Cookware
CAUTION
•Foods packaged in aluminum foil should not
be placed directly on the glass ceramic surface for
cooking; aluminum foil can melt and cause perma-
nent damage.
•Plastic, paper and cloth can melt or burn
when in contact with a hot surface. Do not let
these items come in contact with the hot glass
ceramic surface.
•Do not allow pans to boil dry. This can
permanently damage the pan, the element and
the cooktop glass.
Cookware Tips
• Use of pots and pans with rounded (either
concave or convex) warped or dented bottoms
should be avoided. See drawings above.
• Make sure the bottom of the pot or pan being
used is clean and dry.
• Use pots and pans with thick, smooth metal
bottoms.
• Do not slide metal pots across the cooktop.Pans
may leave marks. (See Page 9 for cleaning.)
• Do not use glass pans as they may scratch the
surface.
