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.
