How to Re-pressurise an Ideal Logic Boiler

Loss of system water pressure
indicates the central heating system pressure.
If the pressure is seen to fall below the original installation
pressure of 1-2 bar over a period of time then a water leak may
be indicated. In this event conduct the re-pressurising procedure
as shown below. If unable to do so or if the pressure continues to
drop it’s time to call in a qualified engineer
THE BOILER WILL not OPERATE if the pressure has reduced to 0.3 BAR or less.
To re-pressurise:

Ensure filling loop isolation valves are closed. Turn the filling loop isolation valves to the open position. The system will now fill. Wait for pressure gauge to reach between 1 and 1.5 bar. Close the isolation valves.
