About Use
The appliance is intended solely for use in the
household and must not be put to any other uses.
Use the appliance to prepare meals only. It must not
be used to heat up the room in which it is installed.!
Use of a gas cooker generates heat and humidity
in the room where it is installed. This is why atten-
tion must be paid to good kitchen ventilation.
The natural ventilation openings must be kept
unobstructed. Prolonged use of the appliance
with several or all rings may call for additional
ventilation such as opening a window or a door,
or stronger air extraction by an extractor hood.
To guarantee good combustion, the room in
which the appliance is installed must have
a minimum volume of 20 m3and must possess
a door that opens outdoors or a window that
can be opened.
Keep the ventilation openings at the back of the
appliance free at all times.
Only use the burners after placing pots and
pans on them. Do not heat up any empty pots
or pans; this may result in a build-up of heat. Use
pots and pans with thicker bottoms because heat
distribution is particularly improved in the low
setting. Using pots and pans which are adapted to
the burner size increases the efficiency of the heat
from the gas flame, thereby reducing power costs.
It is not permitted to use roasting pans, frying pans
or grill stones heated simultaneously by several
burners because the resulting heat build-up may
damage the appliance.
Do not let adults or children operate the appliance
unsupervised:
– if they are mentally or physically unable to use
the appliance safely and correctly
– if they don’t have the knowledge and
experience to use the appliance safely and
correctly.
Pots with a diameter of less than 90 mm or more
than 280 mm should not be used. When using large
pots, pay attention to keeping to a minimum
distance of 50 mm between the cooking vessel and
combustible surroundings.
Do not use any pots or pans that protrude over the
edge of the gas cooker.
Switch the burners to the low setting whenever you
remove pots or pans briefly. In this way, you reduce
the risk of burns when working next to naked
flames; you also save gas and reduce pollution.
Whenever the gas hob is fitted under an extractor
hood, always cover the rings with pots or pans.
Otherwise, parts of the extractor hood may become
damaged by the extreme heat development or
grease residues in the filter may ignite.
Ensure an adequate supply of air when using
an extractor hood operating in the extraction
mode !
The appliance cannot be used during a power
failure.
In the event of malfunctions, please inform your
specialist dealer or your nearest Gaggenau after-
sales service.
Caution, risk of burns! Do not operate the
appliance with the cover closed! Do not close the
appliance cover until the appliance has cooled
down completely. Do not use the appliance cover as
a surface for placing objects or for keeping things
warm. Wipe away spills before opening the
appliance cover.

3. Operating Principle
6
The appliance features one-hand operation, flame
detection and automatic re-ignition. The ignition is
activated when the control knob is turned.
Should the flame go out during operation, the
appliance will automatically re-ignite the burner.
During a disturbance, the appliance will cut off
the gas supply as a safety measure, to prevent
unburned gas escaping.
The total rated thermal load amounts to:
6 kW referred to Hs* (gross calorific value)
5.4 kW referred to Hi(calorific value)
The specified rated load is defined by installation
of the fixed nozzles.
The gas hob is converted to a different gas
type by nozzle replacement (full and low-burning
nozzles) (see nozzle table on page 14-15).
Simmering
The burner switches the flame on and off when
simmering. You can use simmering for example to
melt choccolate or prepare delicate sauces.
The time slot for switching on / switching off is
approx. 30 seconds.
0 - OFF
Simmering

Switching on
• Place a suitable pot or a pan on the cooking
position.
• Press down the control knob and turn it to the
required position. The burner ignites
automatically.
• When being switched on, a short sound may be
heard when the electronic of the gas hob opens
the gas supply valve. When changing the power
level you can also hear a sound. This is a normal
condition.
Should the flame go out during operation
(e.g. because of a draught), the appliance will
automatically re-ignite the burner.
Should the re-ignition be unsuccessful (e.g. burner
is soiled by spilled over food or liquid), the gas
supply is switched off automatically after
10 seconds. Turn the control knob to the OFF
position. After the appliance has cooled down
sufficiently, check if all the burner parts have been
assembled correctly. Check if the burner, the heat
sensor or the electrode have been soiled.
Switching off
Fully turn the control knob to the OFF position.
The electronics of the appliance switch the gas
supply off.
Safety Deactivation
The appliance switches off automatically if it has
been operating for an extended period of time. The
time until switching off depends on the setting
(level 12 = 1 hour, level 1 = 4 hours).
Turn the control knob to the OFF position. Then you
can operate the appliance as usual.
4. Operation
Only light the burner if all burner parts are dry, and
assembled correctly. Otherwise, malfunctions may
occur or the appliance may switch off.

Keeping warm
Switch to the high setting in order to reach the required temperature quickly. Then switch back to a lower
setting.
The values given above must be looked upon as recommended values. The heat required depends not
only on the type and condition of the food, but also the size and contents of the pot.
Due to the high performance of the cooktop, fat and oil will heat up quickly. Never leave the cooktop
unattended, fat can ignite, food can burn.

Pots with a diameter of less than 90 mm or more
than 280 mm should not be used. When using large
pots, pay attention to keeping to a minimum
distance of 50 mm between the cooking vessel and
combustible surroundings.
When buying pots, pay attention to the fact
that the manufacturer frequently specifies the top
pot diameter, which is generally larger than the
diameter of the base.
Observe the manufacturer’s specifications! Use
cooking utensils that the manufacturer states as
being “suitable for gas". Use pots with heat resistant
handles.
Use pots and pans with a thick base, because heat
distribution is particularly improved in the low
setting. Using the correct size of pots and pans for
the burner ensures improved cooking performance
and energy efficiency.
To ensure an even distribution of heat, center the
pot above the burner. The flames should be
covered by the pot base.
Place the pot or pan securely and level on the pot
grid. Turn the pan handle to the side, it should not
point to the front. In order to guarantee a secure
position on the pot grid, the pot base should be flat
and not warped or dented.
Placing a fitting lid on the pot will shorten cooking
times. Through a glass lid you can watch the
cooking progress without having to take the lid off.

Keep the ventilation openings on the rear of the
appliance clean. Do not block the ventilation
openings.
The burners (burner head cover, burner ring and
burner head) will change their color during
operation and become darker. This change in color
will not influence the use-value.
Please thoroughly clean the appliance before
operating it for the first time and after every use.
Do not use scouring agents, abrasives or chemically
aggressive cleaners (for example oven cleaner)!
Do not use any nitro polishing agents for cleaning!
Do not use any abrasive sponges either.
Before cleaning, please wait until the cooktop
has cooled to hand-warm !
• First lift the pot grid with both hands (be careful
not to scratch the base).
• Remove the burner head cover, the burner
rings and the burner head.
• Important! Only clean the burner parts when
cold!
• Soak burnt-in remainders in a little water and
detergent. This loosens even the most stubborn of
soiling. Do not use any abrasive agents and
abrasive sponges.
• Only use very little water to clean your cooktop.
Be careful that no water enters the burner base.
• As the result of heat development, slight dis-
coloration can appear on the stainless steel
surface. Do not attempt to scrape away such
discoloration. This damages the surface.
Distribute stainless steel care agents uniformly
and thinly on the hob. This will ensure an even
surface and will keep your hob in a good
condition for a long period of time.
• Make sure the burner parts are dry before
assembly. Only operate the appliance with all
parts dry. Damp burner parts will cause
malfunctions when igniting or unstable flames.
• When assembling the burner parts, make sure
that the burner ring and burner head are placed
in such a way that the locking lugs fit in the
corresponding recesses.
7. Cleaning and Care
Note: to avoid jeopardising the electrical safety of
the appliance, do not use high-pressure or steam
jet cleaning devices – risk of short circuits!
Caution, risk of burns! Before cleaning,
please wait until the cooktop has cooled to
hand-warm. Never switch on the cooktop
