One good thing is there is very easy access to clean it. It looks like all this crap will fall into the firing chamber though and I'll have to take off the burner plate to access it. I don't see any easy access to that.
I have an HB smith oil boiler with carlin buner on it also. The thing is a soot generator. You cannot guess at the settings and get a clean burn. You need the right tools to measure combustion and they are expensive, so I never bought them. They make brushes to clean the boiler but I found the first pass requires a simple steel rod to knock the big clumps of soot out. The brush has to be just the right size or it won't make it through between the pins.
Yes, you have to take off the burner plate to access the fire box. Disconnect the electric. Disconnect the oil piping if it is not flexible enough to allow the burner to be set to the side. Also take off the flue to access the flue connector on the boiler. Pain in the a**.
I brush down the boiler from the side first, then take off the buner plate and vacuum out the soot and then brush the inside surface of the fire box. The flue is done last.
My boiler is now strictly a backup boiler and sits there unused.
