    That’s a section of the heat exchanger, but unless it’s leaking there, it’s not causing an ignition failure.

    It looks like your pilot may be burning too rich and causing a soot buildup.

    Is the boiler on natural or LP gas?

    It's natural gas. What's happening is that black stuff is falling on ignitor and causes the boiler to constantly refire until I clean it again. It s happening every other day now, that it has to be cleaned.

    Also, it is a intermittent ignition.

    Look at the pilot burner (#7 on the diagram) when it is burning make sure that it is not YELLOW. it should be blue.

    If it is burning YELLOW then the burner is defective and may need to be replaced. I am not sure if this is your exact burner assembly without the actual Crown model and Serial Number
