supply. Once the appliance has been installed, it is necessary to check for gas leaks from the pipe fittings; do not use a

flame for this purpose but a non-corrosive substance such as soapy water or foamy substances as contained in leak-

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 is read by inserting a gauge (minimum resolution of 0.1 into the relative pressure outlet (see fig. A).

Remove the hermetically closed screw and insert the gauge pipe.

After reading, put back the screw tightening it hermetically and check for pressure leaks.

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 natural gas H G20

The connection pressure for natural 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.

RULES FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS

Our appliances are tested and regulated with liquid gas (see plate inside).

The conversion or adaptation to another type of gas must be carried out by a specialised technician. The nozzles for the

various types of gas are in a packet supplied with the appliance and marked in hundredths of mm (see the "Technical

Data" table).

SUBSTITUTING THE NOZZLE IN THE MAIN BURNER

•

In order to operate inside the appliance, it is necessary to empty the water container.

•

Remove the small knob from the panel by unscrewing it.

•

Remove the front fixing screws from the panel, remove the start-up cable from the piezoelectric ignition device.

•

Using a suitable spanner, unscrew the nozzle and substitute it with the right one (see the "Technical Data" table).

•

The main burner does not require any regulation of the primary air.

SUBSTITUTING THE NOZZLE IN THE PILOT BURNER

The flame of the pilot burner has fixed air.
