We have just brought a new house and I can’t get the pilot light to ignite on the boiler, it is at least a few months since the boiler has been used. Where to I start on tracking down the problem?
(It is an old UK system –pre electronic , the boiler heats up water that then heats the house)
The gas fire works, so we must have gas!
The controler is a Honeywell V4600C, I have check at the inlet pressure measure point and there is gas. Sometimes I can see a flame for a very short time when I try to light the pilot light, then the flame goes out.
