hello,
I have a problem with this same combi (ravenheat 820/20).
I really need the wiring diagram and service manual, so I can properly diagnose the fault. The burner runs continuously, even when the selector switch is set to DHW (all taps are closed) and the time switch is set to 'off'.
Has anyone seen this before?, could it be the diverter valve?
Many thanks for your help.
