77 DRAINING THE BOILER
1. Refer to frame 57.
2. Close all the water isolating (CH and DHW) valves on the boiler inlet.
3. To drain the central heating circuit : Attach a length of hose to the CH drain point and open the drain valve.
4. To drain the domestic hot water circuit . As there is no direct drain for the domestic hot water circuit, depending on
the location of the boiler, opening the lowest hot water tap may drain this circuit. However it must be noted that some
residual water will be experienced during replacement of components.
5. After replacing any component on the boiler, close the drain valve, remove the hose and open all system
isolating valves (re-pressurise as appropriate with filling loop) before proceeding to check operation of the
boiler.
6. Check operation of the boiler. Refer to Frames 45 & 46.
1. Refer to Frame 57.
2. Swing the control box down into the servicing
position. Refer to Frame 51.
3. Drain the boiler. Refer to Frame 77.
4. Remove the divertor valve actuator head. Refer
to Frame 67.
5. Unscrew the top connection to access the
internal parts.
6. To allow residual water within the waterset to
drain, slacken CH isolation valve union nut
connecting isolation valve to waterset.
NOTE. Failure to do this may result in
compression of trapped residual water
during diverter valve reassembly, resulting in
damage to the pressure gauge located on
the CH isolation valve.
7. Fit the new valve cartridge mechanism
ensuring correct fit of the pin.
8. Reassemble in reverse order ensuring CH
isolation valve union is reconnected.
9. Refill the boiler. Refer to Frame 36.
10. Check operation of the boiler. Refer to Frames
45 & 46.
