Before testing the boiler, it is advisable to check:
- the smoke evacuation duct and the terminal part are installed
in accordance with the instructions: with the boiler on no
leakage of products of the combustion from no gasket;
- the boiler power supply voltage is 230 V - 50 Hz;
- the system is properly filled with water (pressure al
manometer 1-1.3 bar);
- any shut-off cocks on the pipes of the plant are open;
- the mains gas corresponds to the boiler calibration one:
otherwise, proceed with the conversion of the boiler to the use
of available gas: this operation it must be performed by
qualified technical personnel;
- the fuel supply cock is open;
- there are no combustible gas leaks;
- the main electrical switch upstream of the boiler is inserted;
- the 3 bar safety valve is not blocked;
- there are no water leaks;
