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). If these data do not
correspond, it is necessary to do a transformation of the device (see paragraph transformation).
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.
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 - II2H3P - 20; 37 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.
for LPG (G31): entry gas pressure (Pn) 37mbar; if it’s lower than (Pmin) 25 mbar or higher than (Pmax) 45 mbar, turn off
the device and the contact the installer to solve the problem.
