I have a Ideal classic FF350 boiler.
It has just started having problems on initial firing. The pilot lights and the main gas burner ignites. The flame is somewhat spluttery and it has a yellow hue. It splutters for a while with occasional stop and re-fires. It also sometimes has the ignition spark repeating. This only happened when the boiler is started from cold. It takes about 3-5 minutes to settle onto a steady blue flame. If it needs to turn off an on when warm/hot during normal running the re-firing is fine, so it only seems to be a problem when cold.
My only thought was some debris has fallen down into the gas burner. It recently had a new fan fitted so thing could have been disturbed.
Any suggestions.
