Conversion to Natural Gas or LPG
Replacing the Burner Injectors
If the NATURAL GAS/LPG conversion kit is not supplied with the appliance this kit can be purchased by
contacting the After-Sales Service.
Choose the injectors to be replaced according to the table below.
The injector diameter, expressed in hundredths of a millimetre, is marked on the injector body.
To replace the injectors proceed as follows:
– Remove the pan supports, the burner caps and flame speaders.
– Using a wrench, substitute the nozzle injectors “J” (Figs. 19 - 20) with those most suitable for the kind
of gas for which it is to be used.
The burners are made in such a way so as not to require regulation of the primary air.
