1.Drain the boiler primary circuit and undo the nut on the pressure gauge capillary.

2.Undo the screws securing the gauge retaining bracket.

3.Remove the bracket and gauge assembly. Depress the barbs on the side of the gauge and remove the retaining bracket.

4.Examine the sealing washer, replace if necessary.

5.Reassemble in reverse order.

14.18Hall Effect Sensor (Fig. 92)

1.Ease the sensor upwards off the hydraulic inlet manifold assembly.

2.Disconnect the electrical plug from the sensor.

3.Connect the plug to the new sensor. Carefully fit the new sensor to the hydraulic assembly, ensuring it is fully down.

14.19Pressure Relief Valve (Fig. 93)

1.Drain the boiler primary circuit.

2.Disconnect the discharge pipe from the valve. Using a suitable hexagon key undo the grub screw sufficiently to release the valve.

3.Note the orientation of the valve, rotate it and withdraw it from the manifold.

4.Fit the new valve and ‘O’ ring seal and set to the previously noted orientation. Reassemble in reverse order.
