My central heating boiler has started to play up, the pilot light keeps going out after about 15 miniutes, some times it stays on all day when I over ride it, but then lately it has become tempermental, working as I said above can anyone offer any advice please, I am retire now and on limited income so dont want to be spending money I dont need to, but its cold.

Hi Mike
I agree with Pete, changing the thermocouple is cheap and sounds likely to solve the problem.
If you have loud bumping and banging noises coming from the boiler though I Have the same boiler and was told that the boiler should have a permanent mains supply and the pump should be wired up as per the diagram in-side the gold pull off cover. This is to allow the boiler to run the pump after the heating demand has stopped to cool the heat exchanger.

Has anyone got a user manual for this type of water heater?

Try fitting a new thermocouple, not an expensive item
