If the preparation of the appliance does not correspond to the family of gas available on site, it is mandatory to carry out
a transformation of the appliance for adaptation to the type of gas present. In this case it is absolutely necessary to
inform the authorized technical service center.
The commissioning of the appliance with the expected thermal power depends on the inlet pressure and calorific value
of the gas as well as the nozzle, the pressure to the same and the correct supply of primary air.
The inlet pressure that allows the operation of the appliance is included for the several types of gas within the limits
indicated in the following table. Outside these limits, the commissioning of the apparatus is prohibited. If a pressure
different from what is shown in the table is found, it is advisable to consult the body or company that supplies the gas or
the company that carried out the plant.
The lower calorific value of the gas is needed from the entity or company that supplies the gas and must correspond to
what is reported in the technical sheet
12.
GAS CONNECTION: INLET PRESSURE CONTROL (only for gas cylinders)
The gas connection must be conducted by professionally qualified personnel and must meet the requirements of current
local and national rules and/or regulations. Check that the supply gas follows that indicated in the technical data plate
located in the rear of the machine.
The largest inlet pressure is 50 mBar.
Below is the sign for any pressure checks by means of a pressure gauge.
1)
inlet pressure socket
2)
outlet pressure taking shows the pressure at the burner
3)
pressure regulator
The loose safety screws for pressure measurement, MUST ABSOLUTELY be screwed back once the measurement has
been carried out.
Check the correct positioning of the adjustment collar (if any). Con machine in operation, and side doors closed, check
the correct pressure at the nozzle: use the following table.
For feeding from the network use an approved pipe: the pipe must be equipped with an expansion ring in case the pipe
is rigid.
For the dimensions of the gas supply pipe refer to the attached technical sheet: the external pipes must be adapted to the
type of gas used and follow the current legislation of the country of destination. Install a suitably sized pressure reducer
on the gas supply line and equip the line with a manually closing valve.
ATTENTION!
Gas valves have a pressure limit of 50mbar. Exceeding this pressure can cause the valve membranes to rupture.
Therefore, perform a correct check of the pressure available upstream of the machine, before connecting the gas
supply.
