Gas maintenance
Replacement of the injectors of the burners
Select the injectors to be replaced according to the "Table for the choice of the
injectors".
The nozzle diameters, expressed in hundredths of a millimetre, are marked on
the body of each injector.
If the injectors are not supplied they can be obtained from the "Service Centre".
Replacement of the injectors of the cooktop burners
To replace the injectors proceed as follows:
* Remove pan supports and burners from the cooktop.
* Using a wrench, substitute the nozzle injectors "J" (figs. 9.10, 9.11) with those
most suitable for the kind of gas for which it is to be used.
The burners are conceived in such a way so as not to require the
regulation of the primary air.
