3.13 Filling the system
Once all boiler connections have been completed, CH system can be filled.
The procedure is to be cautiously carried out, following each step:
• Open the bleeding valves on all radiators and verify the boiler automatic valve operation.
• Gradually open the relevant filler cock, checking any automatic bleeding valves installed in the system properly work (see Fig. 2 Filler cock).
• Close all radiator bleeding valves as soon as water starts coming out.
• Check on pressure gauge that water pressure reaches the 1÷1.3 bar reading.
• Shut the filler cock and bleed any air out again, by opening the air bleeding valves on radiators.
• Start the boiler and bring the system to working temperature, stop the pump, and repeat air bleeding procedure.
• Allow the system to cool and restore water pressure to 1÷1.3 bars.
WARNING
The low water safety pressure switch will not electrically enable the burner ignition when water pressure is below 0.4-0.6 bar.
The CH system water pressure must not be lower than 1 bar. Otherwise, fill the heating system.
The procedure is to be followed while the system is cold.
Pressure gauge is used to read pressure inside the heating circuit.
WARNING
As for water treating in the domestic heating systems in order to optimise efficiency and safety, ensure a long life, trouble-free
operation of auxiliary equipment, minimise power consumption, thereby integrating the standards and rules in force in the
country of installation, it is recommended to use specific products suitable for multi-metal heating systems.
