The gas connection must be done with steel or copper pipes, or otherwise with flexible steel pipes in compliance with
the national norms, if any exist. Each appliance must be provided with a cut-off cock for rapid interruption of the gas
supply. Once the appliance has been installed, it is necessary to check for gas leaks for 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.
NB: The year of the appliance manufacture is shown in item "N" on the data plate. The first two numbers (e.g. 93..)
represent the year of manufacture.
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 with a gauge (minimum resolution of 0.1 mbar) inserted in the relative pressure outlet..
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.
CHECKING PRIMARY AIR TO THE MAIN BURNERS AND PILOT NOZZLES
All the burners are fitted with an air regulator by means of which the primary air can be varied thanks to an adjustable
bush that can be locked with a screw. In the "Burner Technical Data" table you will find the approximate values for the
"h" parameter (primary air). The flow of primary air must be regulated so there is no detachment of the flame when the
burner is cold or a return of the flame when the burner is hot.
The pilot air is regulated when the appliance is tested and inspected for the gas it is set for.
If you are going to change to a different type of gas, regulate the air by means of the adjusting bush until the flame stops
sputtering and becomes an intense blue colour.

RULES FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS
Our appliances are tested and regulated with liquid gas (see data plate).
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 supplied in a packet and are marked in hundredths of mm (see "burners" technical data table).
