DISPOSALS FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS
Our appliances are tested and regulated with liquid gas /see plate).
The conversion or adaptation to another type of gas must be carried out by a specialized technician. The nozzles for the
various types of gas are supplied in a packet and are marked in hundredths of mm (see table of "burners" technical
data).
SUBSTITUTING THE NOZZLE IN THE MAIN BURNER Fig.A
• Remove the front fixing screws from the panel (see figure A, pos. 02), remove the start up cable from the
piezoelectric ignition device (03).
• Using a suitable spanner, unscrew the nozzle (09) and substitute it with the right one (see table of "burners"
technical data).
• The main burner does not require any regulation of the primary air.
SUBSTITUTING THE NOZZLE IN THE PILOT BURNER Fig.A
La fiamma del bruciatore pilota ha l'aria fissa.
L'unica operazione necessaria é la sostituzione dell'ugello (08) secondo il tipo di gas.
Bisogna quindi svitare le viti come specificato al punto precedente con una chiave adeguata svitare il raccordo) e
sostituire l'ugello (08) con uno adeguato. Con l'ugello adatto la fiamma deve lambire la termocoppia (06).
Important!
After having effected the conversion to another type of gas, it is necessary to update the data plate, indicating the type
of gas for which the appliance has been converted.
