The pilot light on this (Protherm 60-80 CI) is out and will not re-ignite. I haven't got the manual and I am totally lost on how to get it to light up again.
All else seems to be fine about it, as much as I can tell anyway. It's light is on and it makes all the usual noises right up the point where the flame kicks in.
