Gas Setup
The gas type in the gas pipe network must be checked by a qualified technician that, if necessary, replaces
the nozzle, adjusts the primary air and sets the type of gas on the oven control panel and apply the label.
Nozzle replacement and primary air adjustment
Using the table in the attached technical data sheet, replace the main injector and adjust the primary air using
the corresponding bushing. This procedure should only be carried out once the gas valve upstream of the
oven has been shut off and the power supply disconnected. Make sure that the diameter measurement of the
injector to be replaced is stamped on it, in hundredths of a millimetre (1/100 mm). The injector is located at
the rear, on the bottom left-hand side. To replace the injector and adjust the primary air, proceed as follows
(see illustration below):
• Loosen screw A.
• Adjust bushing B in accordance with the information provided in the
attached table.
• Unscrew and remove injector C using a 13 mm spanner.
• Install the injector most suited to the type of gas supplied (see relevant
technical table).
• Position bushing B at the correct distance H (see relevant technical table).
• Re-tighten screw A.
There are 2 types of nozzle:
- one suitable for G20, G25 and G25.1 gas
- one suitable for G30 and G31 gas
