finder sprays. All our appliances undergo careful testing: the type of gas, the operating pressure and the category are
indicated on the data plate.
The appliances must be checked in such a way as to verify that the heat output is correct:
• The heat output (thermal power) is indicated on the data plate of the appliance.
• Firstly, check that the appliance can be used with the type of gas supplied; then check that the indication on the
plate corresponds to the gas to be used. For converting to another type of gas, check that the type of gas complies
with what is stated in this instruction manual.
The pressure must be read by inserting a gauge for liquids (e.g. a U gauge). With a minimum definition of 0,1 mbar,
into the relative pressure outlet (see fig. A position B).
Remove the screw from the airtight pressure outlet, connect the rubber pipe of the U gauge and read the pressure.
After reading, remove the flexible pipe of the gauge, put back the screw, tighten hermetically and check the pressure
tightness.
Connection for liquid gas G30/G31
The connection pressure for liquid gas is 30 mbar with butane and 37 mbar with propane.
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one supplied
by the manufacturer.

Connection with methane gas H G20

The connection pressure for methane gas is 20 mbar.
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one supplied
by the manufacturer.
All burners are provided with special injectors which do not require regulation of the primary air.

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.B

• Remove the front fixing screws from the panel (see figure B, 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.B

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).
