3.1

Central Heating System Pressure

1. The water pressure in the central heating system is
indicated by the pressure gauge.

2. With the system cold and the boiler not operating the
pressure should be at least 0.5 bar. During operation the
pressure should not exceed 2.5 bar, and will normally be
between 1.0 and 2.0 (Fig. 1).

3. A pressure of 3 or greater indicates a fault. The safety
pressure relief valve will operate at a pressure of 3 (Fig. 3). 

It

is important that your Installer or Service Engineer is
contacted as soon as possible.

4. The minimum pressure for correct operation is 0.5. If the
pressure falls below 0.5, this may indicate a leak on the
central heating system (Fig. 2).

3.2

To Repressurise the System 

1. The procedure is for the optional filling loop kit when
fitted. However, even if your boiler has an external loop, the
principle is similar.

2. Look at the boiler from underneath. There will be two taps
at the end of copper pipes, one with a blanking cap on the
end. Do not operate these taps yet.

3. Your installer will have left a metal braided hose (the ‘filling
loop’) with you for safe keeping.

4. This loop MUST be connected to the taps. Remove the
blanking cap and set aside.

5. Connect the loop to the taps with the wing nuts. These
should be hand tightened.

6. Carefully open the handles on both taps and check the
boiler pressure gauge. Once the needle on the gauge is
above the 0.5 mark both taps can be closed.

7. Undo the two wing nuts, remove the loop and refit the
blanking cap. Put the loop in a safe place for future use.
