I have two broken wires in my boiler which are coloured blue and I belive that thay control the lighting of the boiler, I just wondered if it matters which way round thay go as there is no ather identifaction on the wires?
It would help a great deal if you could determine - and say - where the wires run to. I should think ALL the wires in your boiler have something to do with the control of the lighting.
