My Boiler
My combi boiler is a Vokera 20-80 RS Flowmatic.
I have a number of issues with it.
1) Sometimes, in warmer weather when I switch heating on the pump starts up but the gas will not fire up (pilot light is on)
2) When the heating is working normally and I turn on the hot water tap it makes a big clunk every time.
Questons:- What part of the boiler is it that tells the gas valve to fire up?
What on earth is causing the clunk?
Is it possible to get service/wiring diagram for this model bearing in mind it's no spring chicken.
Thanks in advance
