Open the valve for filling the heating installation
and fill it with the heating medium.
4.
Close the vent when the heating medium flows
out of it continuously (without air bubbles).
5. Control the manometer showing pressure in-
crease. Fill the system until the pressure of 2 bar,
and then close the filling valve.
6. Start the circulation pump of the heating system
every now and then, while opening the vents
placed on the heating circuit.
7. Open the safety valve until the pressure at the
manometer falls down to about 1 bar of the nor-
mal operating range.
8. If, while venting, the pressure drops down below
