Electrical connection
The appliance must only be connected to the power supply by a
licensed professional. The appliance must be installed in
accordance with the most recent IEE guidelines (Institute of
Electrical Engineers). The appliance may be damaged if
incorrectly connected.
Make sure the voltage of the power supply corresponds to the
specified value on the rating plate.
Ensure that the power supply is properly earthed and that the
fuse and the wiring and piping system in the building is
sufficiently dimensioned for the electrical power of the
appliance.
It is recommended that you configure the circuit for the
appliance to 16 A.
Observe the following points when routing the service cable:
■
Do not pinch or squeeze the cable.
■
Keep the cable away from sharp edges.
■
Do not bring the cable into contact with parts that can reach
temperatures of more than 50 °C above room temperature.
Connecting the appliance to the power supply
The appliance corresponds to protection class 1 and may only
be operated with a protective earth connection.
The appliance must be disconnected from the power supply for
all installation work.
The appliance must only be connected to the power supply with
the power cable provided.
Contact protection must be ensured by the installation.
Only a licensed expert may connect the appliance. He is subject
to the regulations of the local electricity provider.
Power cable with a plug with earthing contact
Connect the appliance to the enclosed plug with earthing
contact to a properly installed earthed socket. The socket must
be accessible after installation. If this is not the case, an all-pole
isolating switch with a contact gap of at least 3 mm must be
included in the installation.
Gas connection
The appliance must be connected in accordance with the
currently applicable regulations. Before installing the appliance,
check that the local conditions (type of gas and pressure) are
compatible with the appliance settings. The permissible
appliance settings can be found on the rating plate. The
appliance must be connected to the gas lines and seals by a
professional in accordance with currently applicable standards.
Gas connection on the appliance
The gas connection is located at the rear of the appliance.
A connection angle (EN ISO 228 G1/2 male - 228 G1/2 male)
and an adapter piece (EN ISO 228 G1/2 - EN 10226 R1/2) are
supplied with the appliance.
Default setting of the burners
The burners are preset for natural gas G20 (20 mbar). A nozzle
set for liquefied gas G30 31 (28 -30/37 mbar) is supplied with
the appliance.
Accessories
You can buy accessories from the after-sales service, from
specialist retailers or online.

Gas connecting line with conical thread (EN 10226 R1/2) - Fig.
6a
Only use connecting cables or flexible hoses which comply with
the applicable regulations and which are approved for this
purpose.
1. Screw the angle (3) and the seal (2) to the gas connection (1)
2. Hold the angle (3) with a spanner and screw the adapter piece
(5) and the seal (4) to the angle.
3. Hold the adapter piece (5) with a spanner and screw it to a
fixed connecting line or a flexible gas connecting hose (6).
Only use approved sealing compound to seal the thread.
Gas connecting line with cylindrical thread (EN ISO 28 G1/2) -
Fig. 6b
Only use connecting cables or flexible hoses which comply with
the applicable regulations and which are approved for this
purpose.
1. Screw the angle (3) and the seal (2) to the gas connection (1)
2. Hold the angle (3) with a spanner and screw it to a fixed
connecting line or a flexible gas connecting hose (5) and the
seal (4).
Flexible hoses - Fig. 7
For flexible hoses, observe the following points:
■
Do not pinch or squeeze hoses.
■
Do not subject the hoses to twisting or pulling forces.
■
Keep the hoses away from sharp edges.
■
Do not let the hoses come into contact with parts that may
reach a temperature higher than 70 °C above room
temperature.
■
Make sure that the full length of the hoses is accessible for
inspection.
Installing the safety valve
The installation of a safety valve for opening and closing the gas
supply is a compulsory requirement. Fit the safety valve
between the gas supply line to the appropriate room and the
appliance. Ensure unhindered access to this valve.
Checking for leaks
After connecting the gas line, check the connections for leaks
using soapy water.
Initial use
Switch the appliance on as described in the instructions for use.
Light all the burners and check that the flames remain stable at
both the high and low settings.
Converting the gas type
If the appliance is not already set up for the existing type of gas,
the appliance must be converted. The conversion to a different
type of gas must be carried out by an authorised expert in
accordance with the applicable regulations. The type of gas and
pressure that was preset at the factory are indicated on the
rating plate.
In order to convert to a different type of gas, the nozzles must be
replaced and the low flame and primary air may have to be
adjusted.
Replacing the gas burner nozzles - Fig. 8
1. Disconnect the appliance from the electricity supply.
2. Remove the pan support.
3. Remove the burner cap A and burner cup B from the burner C
(Fig. 8a).
4. Remove the nozzle D and replace it with an appropriate nozzle
for the new type of gas (Fig. 8b).
5. Replace the old gas label with the new gas label.
The new gas label is supplied with the nozzle set.
6. Place the burner cup B onto the burner C.
7. Position the burner cap A exactly on top of the burner cup B
(Fig. 8c).
8. Refit the pan support.
Setting the minimum gas flow - Fig. 9
1. Switch on the gas burner.
2. Turn the control knob for the gas burner towards the small
flame setting.
3. Remove the control knob for the gas burner.
4. Adjust the internal setting screw until a stable flame is burning
correctly.
5. Loosen the setting screw to increase the gas flow or tighten it
to decrease the gas flow.
Note: Make sure that the flame does not go out when the gas
flow is quickly changed between maximum and minimum, and
vice versa.
The setting is correct when the height of the small flame is
approx. 3 to 4 mm.
6. Refit the control knob for the gas burner.
