4.0System Pressure & Temperature

4.1Central Heating System Pressure

1.The normal operating water pressure is between 1 and 2.5 bar (Fig. 4). If the pressure exceeds 3 bar the safety pressure valve will operate and a fault is indicated (Fig. 6). Contact your installer.

2.It may be necessary to repressurise the system occasionally (Fig. 5). A filling device (the filling loop) will be fitted on the system. If you are unsure of its position, or cannot identify it, consult the installer who fitted the boiler.

3.The filling loop will probably consist of two taps and a separate metal braided hose with connection fittings.

4.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.

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

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

7.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.

4.2Temperature Control

1.Central Heating: The central heating hot water flow temperature can be adjusted between 30° C (± 5° C) minimum and 85° C (± 5° C) maximum.

2.Turn the control knob clockwise to increase the temperature (Fig. 7). In normal winter usage we recommend that the central heating temperature be set at maximum.

3.Domestic Hot Water: The temperature of the domestic hot water can be adjusted by turning the control knob clockwise to increase up to a maximum of 65°C (Fig. 8).

4.The temperature of the water is also dependent on the water flow rate and the temperature of the mains coming into the house.

5.By slightly reducing the flow from the tap the temperature will increase up to the maximum if required.

6.The flow rate can be reduced down to as low as 2.5 litre/min. The boiler will still recognise the need to heat the water.
