1. Important Notes

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 35 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 ever use the burners after placing pots
and pans on them. Do not heat up any empty
pots or pans.
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.
Pots with a diameter of less than 90 mm or more
than 280 mm / 320 mm for the large (WOK)
burner 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.
A minimum distance of 50 mm must be observed
between the control knob / control panel and the
pot or pan. The pot or pan should not touch the
control panel.
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.

3. Operating Principle
The gas hob features two normal burners,
two large burners and a Wok burner.
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 flame setting is infinitely variable between high
and low.
The total rated thermal load amounts to:
17.0 kW referred to Hs* (gross calorific value)
15.3 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 17-19).

Switching on
• Place a suitable pot or a pan on the corresponding
cooking position.
•Press down the control knob for the corresponding
cooking position and turn it to the required
position between the and symbols. The burner
ignites automatically.
• When using large pots or pans you should ignite
the burner in the low position.
• Every time the gas hob is switched on, the
electronics run an auto test. All electrodes fire
and the required burner ignites after a few
seconds. When switching on further burners, only
the corresponding electrode fires.
• When being switched on, a short sound may be
heard when the electronic of the gas hob opens
the gas supply valve. This is a normal condition.
The flame size can be set continuously between full
and low by slowly turning the control knob.
Indicator light
The indicator light next to the control knob comes
on, if the burner is switched on and the flame burns
correctly.
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), all burners
are switched off, the indicator lights of the burners
that were switched on flash. Turn all control knobs
to the OFF position. The flashing indicator lights will
go out except for the affected burner. This indicator
will continue to flash for a few seconds. After the

assembled correctly. Otherwise, malfunctions may
occur or the appliance may switch off.

appliance has cooled down sufficiently, check this
burner to see if all the burner parts have been
assembled correctly. Check if the burner or the
electrode has been soiled (see trouble shooting
guide on page 16).
Note: if a malfunction occurs on one burner, you
can continue using the remaining burners, however,
you must turn all control knobs to the off-position
first, before recommencing.
Please note when switching on the cold
appliance on the HIGH setting: depending on
the gas type and pressure, it is possible that the
electrode continues to fire, although there is a
flame visible, and then switches off.
Turn all control knobs to the OFF position. Then
turn the control knob for the required cooking
position to any setting except the high position and
leave to warm up for 30 to 60 seconds.
Then you can continue to use your appliance as
usual.
Switching off
Fully turn the control knob to the OFF position.
The electronics of the appliance switch the gas
supply off, if all control knobs are in the off position.

Switch to the high setting in order to reach the required temperature quickly. Then switch back to a lower
setting.
The output of the inner flame ring is the same on the normal, as well as the large burners.
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.
Preferably use the rear cooking zones to prepare meals, that need longer to cook.
Preferably use the larger burners or the wok burner for brief cooking, deep fat frying and brief frying of
large quantities.

Pots with a diameter of less than 90 mm or more
than 280 mm / 320 mm for the large (WOK)
burner 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.
A minimum distance of 50 mm must be observed
between the control knob / control panel and the
pot or pan. The pot or pan should not touch the
control panel.
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.

The Wok and Accessories
(not included in the scope of delivery)
–The round-bottom wok is the ideal wok for your
gas cooker.
–The wok looks like a hollow semisphere with a
long handle or wooden handle. It has a rounded
base and slanted sides. The thin steel passes the
heat swiftly to the inside, but soon cools down
again as soon as the flame is set to a lower
setting. Therefore, ingredients cannot overcook.
– The diameter is between 35 - 40 cm for 4 persons.
– Make sure that a wok with a rounded base is
positioned safely on the pot grid.
– Woks may consist of various materials. Cast-iron
woks are more stable and keep the heat longer.
– They have a round, high cover. Therefore, they
are also capable of steaming and stewing.
– The semicircular grid is hooked in on the edge of
the wok. On it, you can steam ingredients, you
can allow deep fried foods to drip or you can
keep browned foods warm.
– Use the chan (rounded spatula) or a long handled,
wooden spatula.
– Use a ladle to remove foods.
– Use the strainer to lift deep fried foods from the
fat or large pieces out of a sauce.
– You can use bamboo baskets for steaming.
Cooking in the Wok
You can fry, steam, deep fry, stew and cook normally.
Stir frying is the special cooking method for the
wok. Ingredients cut into small pieces are cooked
as briefly as possible under strong heat and
constant stirring. In the large, round pan everything
can be stirred and turned faster and with greater
ease than in a conventional frying pan. Thanks to
stirring, ingredients do not burn onto the pan.
Surplus oil drains off towards the middle. In next to
no time, you obtain delicious roasted foods, the
pores in meat close and fish becomes nices and
juicy. Vegetables stay crispy, and aromas and
healthy vitamins are retained.
Important: the cooking time is so short that all
ingredients should be ready for cooking before you
begin. The correct sequence is also important. First
place the ingredients with the longest cooking time
in the wok. For example, these are hard-fibred
vegetables such as carrots. Soft vegetables such as
mushrooms or sprouts are added later.
Proceed as follows:
– Pour sufficient oil into the wok to coat the surface.
We advise you to use peanut or or soya oil.
– Heat up the oil to just before the smoking point;
only then begin with stir frying.
– Cut the food into pieces of equal size, but not too
small, thus making sure they will not burn.
– If you are cooking larger quantities, work with
portions as otherwise not all of the food will reach
the hot base of the wok.
– Meals that are ready ca be kept warm on a
minimal flame. Clean the wok after every use and
rub its inside with oil. This will prevent rusting.

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.

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
while cleaning.

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 one of the pot grids on the side with both
hands (be careful not to scratch the base). Then
remove the remaining two pot grids.
• Remove the burner head cover, the burner ring
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 (not on the control panel!).
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.
• Important! Fit the middle pot support first
(be careful to center it over the burner) and
then the pot supports on the side. The
rounded corners of the pot supports on the
side must face out to the side.
