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 20 mbar,

flame needs to be adjusted.

type of gas, you should:
exchange nozzles (see tables below),
adjust the “economical” flame.

The cookers provided by the manufacturer
have burners which are factory-adapted to
use the gas specified on their data plates and
guarantee cards.
