9.2Checking the Burner Pressure

1.Turn on the gas and electrical supplies to the boiler and ensure that all external controls are calling for heat.

2.Set the hot water and central heating temperature controls to maximum and the selector switch to the OFF position (Fig. 37).

3.Slacken the pressure test point sealing screw on

the gas valve and connect a pressure gauge (Fig. 38).

4.Disconnect the sensing tube from the gas valve.

5.Turn the selector switch fully anticlockwise against the spring pressure to the reset position and hold for

2seconds to reset the boiler.

6.Turn the selector switch to the Cental Heating and

10.2 mbar

Propane

21.8 mbar

If not, check that the gas supply pressure is correct (Natural Gas 20mbar, and Propane 37mbar).

9.The pressure can be adjusted if required.

10.To check and set minimum pressure first remove one of the modulator wires.

Adjusting the Pressure (Fig 39)

11.Remove the plastic protection cap from the pressure adjustment nuts on the valve.

12.The smaller nut (5mm) adjusts minimum pressure and the larger nut (8mm) maximum pressure.

13.Using a suitable spanner adjust the relevant nut until the correct pressure is achieved.

14.Once the pressure has been set turn the boiler off and disconnect the pressure gauge.

15.Tighten the pressure test screw and refit the modulator to the valve. Reassemble in reverse order.
