3.1Central Heating System Pressure

1.The normal operating water pressure is between 1 and 2.5 bar (Fig. 1). If the pressure exceeds 3 bar the safety pressure valve will operate and a fault is indicated. Contact your installer.

2.It may be necessary to repressurise the system occasionally (Fig. 2). A filling device (the filling loop) will be fitted on the system.

3.If you are unsure of its position, or cannot identify it, consult the installer who fitted the boiler.

4.The filling loop consists of two taps and a separate metal braided hose with connection fittings.

5.Only when repressurising should the hose be connected between the two taps. Ensure that the nuts on the pipe ends are tightened onto the taps.

6.Fully open one of the taps first, and then while watching the pressure gauge, carefully open the second tap.

7.When the needle on the gauge is indicating 1 or more turn both taps off.

8.Disconnect the metal braided hose from the taps (a small amount of water may be present) and remove it. Keep the hose in a safe place for future use.
