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 hob generates heat and humidity in
the room where it is installed. This is why attention
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 m
3
and 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.
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.
In the event of a spill or boil over the burner ring
and head may need to be removed and cleaned.
Perform when burner is cold. For identification of
burner ring and head see page 7.
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 aftersales service.

3. Operating Principle
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:
20.5 MJ (5.69 kW) for natural gas
22.5 MJ (6.16 kW) for propane gas
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 16-17).

Switching on
• Place a suitable pot or a pan on the corresponding
cooking position.
• Press down the control knob for the 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. The electrode fires
and the burner ignites after a few seconds.
• 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.
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 and a signal is
sounded. 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 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.
4. Operation
Only light a burner if all burner parts are dry, and
assembled correctly. Otherwise, malfunctions may
occur or the appliance may switch off.

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.
Page 12
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 discoloration 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

cut-out and align it.
Note: do not stick the hob onto the worktop with
silicone.
• Turn the clamping screws under the countertop
and tighten them evenly. Do not tighten the
clamping screws too tightly, as a uniform sealing
gap should be left all round.
• Connect the appliance to the gas supply.
• Check the installation for gas leaks.

Installing the Spindles
The numbers correspond to the diagram on the
opposite page. Spindle extensions (SV 402-090 /
SV 402-205) are available should the appliance be
installed in a worktop which is non-standard depth.
Loosen the nuts of the spindle covers and remove
covers.
1 Insert the spindles from behind into the fittings of
the control knobs. Be careful that the broader pin
of the control knob fits the broader fitting of the
spindle.
2 The gas taps of the burners must be in the off
position (flat side to the top). Slide the spindles
on the gas taps.
3 Fix the spindles with the screws provided.
Turn the control knob to the off position. Connect
the appliance to the power supply, and check for
correct functioning. If the appliance switches off
there may be air in the gas supply line. Turn the
control knobs to the off position and relight. This
may need to be repeated until the appliance
ignites.

Nozzle Replacement
Changing over to a different gas type
Only authorised specialists are permitted to
change over to a different gas type.
The nozzles needed for the gas type to be set
are available as a conversion kit. Please specify the
appliance type and the required gas type.
The nozzles can be changed on the installed
appliance.
Loads for all gases
For all gas types and pressures, the rated load
is achieved by installing the high and low setting
nozzles for the required gas type (see nozzle
table).
Replacing the low setting nozzles
• Switch off the power at fuse point and close the
gas supply!
• Detach pod grid, burner rings, burner head
covers and burner heads.
• Undo trough securing nuts and carefully detach
the trough. Loosen the nuts of the spindle covers
and remove covers.
• Detach the spindles between the control knobs
and the gas taps.
• Turn the black plastic part so that the recess is
above the nozzle. Screw out nozzle and take
nozzle out with small pliers.
• Replace both low setting nozzles on the gas taps
according to the new gas type and as detailed in
the low setting nozzle table. Fully screw in the
new low setting nozzles.
Important: be careful not to damage the O-ring.
See table on page 16-17
for details of nozzle settings.

Replacing the main burner nozzles of the
normal burner and large burner
• Detach the safety spring on the supply lines.
Leave the electrode connected. Unscrew the
burners from the trough (Torx T20) and pull off the
burner from both supply lines.
• Carefully pull off both main nozzles together with
the O-ring by hand.
• Check whether the O-rings of the new nozzle
seats are fitted correctly. Fully push nozzles onto
the supply lines. Note: do not bend supply lines.
• Push the burners onto the supply lines.
Push the safety springs back on.
• Screw the burners back on the trough.
• Loosen the locking screw and adjust the air
regulation bush according to the nozzle table.
Tighten the locking screw.
• Fit the trough and tighten it firmly.
Checking functions
The flames are adjusted correctly if no yellow tips
are visible and if they do not go out when switching
over swiftly from the high to the low setting.
Please do not forget to stick the new adhesive label
included with the nozzle set over the old adhesive
label on the gas connection, thus documenting the
changeover to a different gas type.

Fitting the Appliance Cover
• The securing brackets are already fitted on the
base.
• Place the appliance cover on the brackets in
upright position and screw it down using the
pre-mounted grub screws.
• Close the appliance cover. It must lie evenly on
the appliance.
• If the cover is not fitted straight, loosen the sheet
metal screws holding the securing brackets and
fit the included shims on the securing bracket
until the appliance cover lies evenly on the panel
edge.
• Again firmly screw down the appliance cover.
Note:
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.
Do not close the appliance cover until the
appliance has cooled down completely. Do not
operate the appliance with the cover closed! This
may damage the appliance and the cover due to
the development of heat.
