3.0 Repressurising System

3.1

Central Heating System Pressure

1. The normal operating water pressure is when the

needle is in the GREEN section of the gauge, between 1

and 2.5 bar (Fig. 1). If the pressure exceeds 3 bar (needle

in the RED section) 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). The needle will be in the lower RED

section of the gauge, between 0 and 0.5.

3.A filling device (the filling loop) will be fitted on the

system. This will be on the boiler itself (Fig. 3), or on

pipework near to the boiler.

4. If you are unsure of its position, or cannot identify it,

consult the installer who fitted the boiler.

5. The filling loop consists of two taps and a separate

flexible pipe with connection fittings.

6. Only when repressurising should the flexible pipe be

connected between the two taps. Ensure that the nuts

on the pipe ends are tightened onto the taps.

7. Fully open one of the taps first, and then while

watching the pressure gauge, carefully open the second

tap.

8. When the needle on the gauge is indicating 1 or more,

in the green section of the gauge, turn both taps off.

9. Disconnect the flexible pipe from the taps (a small

amount of water may be present) and remove it. Keep

the pipe in a safe place for future use.
