Regulating the Burner Minimum Setting
When changing from one type of gas to another, the minimum
tap output must also be correct, considering that in this posi-
tion the flame must be about 4 mm long and must remain lit
even when the knob is turned sharply from the maximum to
the minimum position.
The adjustment is performed with the burner lit, as follows:
–
Turn the knob to the minimum position.
–
Remove the tap knob.
–
Turn the screw “
A
” to the correct setting with a screwdri-
ver (fig. 24).
For LPG, tighten the adjustment screw completely.

Conversion to Natural Gas or to 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 for the Choice of the Injectors”.
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 “

” (Figs. 22 - 23) 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.
