1. Do not allow the flame to extend beyond the
edge of the cooking utensil. This instruction is
based on safety considerations.
2. Do not forget that the unit becomes hot when in
use. Common sense is important. Just because
the flame is out, it does not mean parts still
cannot be hot.
3. This appliance shall not be used for space
heating. This instruction is based on safety
considerations.
4. Be sure to disconnect the electrical supply
before disassembly of the appliance.
5. Keep the appliance area clear and free from
combustible materials, gasoline and other
flammable vapors and liquids.
6. Do not obstruct the flow of combustion and
ventilation air.
7. Do not install the appliance under a suspended
cabinet. For installation under a vapour extractor
hood, a minimum clearance of 650 mm from the
top edge of the pot stand to the bottom edge of
the extractor hood must be observed.
8. The gas pressure regulator supplied with the
appliance must be installed in line with the gas
pipe.
9. The appliance and its individual shutoff valve
must be disconnected from the gas supply
piping system during any pressure testing of the
system at test pressures in excess of 3.5 kPa
(1/2 psig). The appliance must be isolated from
the gas supply piping system by closing its
individual manual shutoff valve during any
pressure testing of the gas supply piping system
at test pressures equal to or less than 3.5 kPa
(1/2 psig).
10.Important:
When using a very large pot, leave a gap of at
least 50 mm (2") to avoid damaging any parts in
counter top wood, plastic or other non-heatresistant materials. Never leave oil or hot fat
unattended.
Note:
To avoid jeopardising the electrical safety of the
appliance, it is forbidden to use high-pressure or
steam jet cleaning devices.
Note:
The name plate is attached to the bottom of the unit
and to the inside of the housing.
This appliance shall be installed in accordance with
the manufacturer’s installation instructions, local
gas fitting regulations, municipal building codes,
electrical wiring regulations, the Installation Code
for gas burning appliances, AS 5601 and any other
statutory regulation. Refer to the AGA Installation

For Your Safety
You must not operate the appliance if it is damaged.
When connecting electrical appliances in the proxi-
mity of the appliance, make sure that connecting
leads do not come into contact with hot cooking
surfaces!
As the user, you yourself are responsible for
maintenance and proper use in the household.
Only ever operate the appliance under supervision.
Do not operate the appliance without pots and pans
placed on it. Make sure that all the burner parts are
correctly fitted.
Caution: the appliance heats up during operation.
Keep children away.
Do not clean the appliance with a steam cleaning
apparatus or with water pressure - risk of short-
circuits!
Isolate the appliance from the mains during every
maintenance operation. To do this, remove the
mains plug or switch off the corresponding
household fuse. Close the gas supply.
Repairs must be carried out by an authorised
person.
No warranty claims can be lodged for any damage
resulting from failure to observe these instructions.
Observe caution with oils and fats. They may
overheat and burn easily.
Foodstuffs that are prepared in fat and oil must only

bags away from children.
Check the appliance for transport damage before
installing it.

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).
