• Keep the ller cock open until the pressure gauge shows a value of 1÷1.3 bar;

Should boiler shuts down frequently occur it means there is boiler malfunction in progress. Contact qualied personnel or an authorised

If you do not, when the pressure increases, the safety valve may activate and discharge water.
