Check list before ignition
After the installation, which has to be carried out by an authorized technician in order with the rules in force, and before
burner's lighting which has to be carried out by a qualified technician, you have to do the following check:
Injectors' check
First of all you have to compare the data on the plat serial number and on the supplementary one about device category
and predisposition to gas type with the characteristic data of the local gas (gas type and pressure). The device must be
turned on according to the thermal capacity forseen for prescribed injectors.
Tank filling
To do these check operations it is necessary to fill the water tank. To fill it with the net water you have to:
- open the cold water discharge cock;
- open the warm water exit cock.
We suggest to open a warm water tap of the domestic system so that air in pipe evacuates.
The necessary time for the filling is strictly connected with tank's capacity.
Control pressure inlet gas (Pn)
This check must be carried out with an U-shaped pressure meter (lowest resolution 0,1 mbar). The pressure meter must
be connected with the pressure tap indicate in picture 7.

Pressure tap (Entry)
Turn on the device by following the instructions for use, and after some minutes check the pressure. The pression must
have the following values:
IT - I2H - 20 mbar
for natural gas: entry gas pressure (Pn) 20 mbar; if it's lower than (Pmin) 17 mbar or higher than (Pmax) 25 mbar, turn
off completely the device and contact the gas distribution company to solve the problem.
Control pressure outlet gas (Injectors pressure)
This check must be carried out with an U-shaped pressure meter (lowest resolution 0,1 mbar). The pressure meter must
be connected with the pressure tap indicate in picture 8.
Measure the injectors pressure through the pressure tap (Exit) and if it's necessary set the injectors pressure using the
adjustment screw shown in picture 9. The injectors pressure must be corresponds to the value indicated in the table of
technical data (See table page 4).
