Connection with a stable pipework
The cooker comes with a G ½” threaded coupling. The connection to gas supply must be done in a manner that excludes stresses in
any point of the pipework or parts of the appliance. Make sure you do not exceed the torque when making the connection (maximum
torque is 20 Nm). Otherwise, the connection may be faulty or leaks may occur.
The gas hose should not touch metal elements of the cooker back shield.
Important!
Each time you replace a reducer, carry out technical inspection of the cooker that covers gas valves and proper
operation of the flame failure cut-off device.
Caution! On completion of the cooker installation, the tightness of all connections should be checked, e.g. applying water with
soap. Do not use fire to check tightness.
ELECTRICAL CONNECTION
ADAPTING THE COOKER TO ANOTHER TYPE OF GAS
This operation may only be carried out by an appropriately authorised fitter.
If the gas the cooker is to be supplied with differs from the gas provided for the cooker by the manufacturer, that is G20 / 25 mbar,
burner nozzles must be exchanged and the flame needs to be adjusted.
In order to adapt the cooker to burn a different type of gas, you should:
• exchange the nozzles (see the gas tables below);
• adjust the “economical” flame.
Caution!
The cookers provided by the manufacturer have burners which are factory-adapted to use the gas specified on their rating
labels.

2. Unscrew an adjusting bolt slightly and adjust

2. Screw in an adjusting bolt slightly and check
the flame size.
In order to perfom adjusting operations, take off the knobs.
Surface burners applied do not require adjustment of primary air. A correct flame has distinct internal cones of blue and green colour.
A short, humming flame or long, yellow and smoking one, without clearly outlined cones, shows improper quality of gas in the house-
hold piping or a damaged or soiled burner. In order to check a flame, heat a burner for around 10 minutes with a full flame, and next
turn the valve knob to the economical flame position. The flame should not go out or jump onto the nozzles.
• The cooker is manufactured to work with a one-phase alternating current (230V 1N~50Hz) and is equipped with a 3 x
1,5 mm
2
connection lead of 1.5 m length with a plug including a protection contact.
• A connection socket for electricity supply should be equipped with a protection pin and may not be located above the
cooker. After the cooker is positioned, it is necessary to make the connection socket accessible to the user.
• Before connecting the cooker to the socket, check if:
- the fuse and electricity supply are able to withstand the cooker load,
- the electricity supply is equipped with an efficacious ground system which meets the requirements of current
standards and
provisions.
- the plug is within easy reach.
