Well, with all that soot all over the place, I can easily see why you thought it was an oil-fired unit lol. Stay safe. The only truly dumb question is the one you don't ask.
Carbon’d up inside and apparently roll out didn’t stop it? Burned inside and out. Hope you will have an easy time removing the boiler from the basement.
I think one of the inner flue passages got clogged due to rust chunks at the hole thru to the water side. Products of combustion build up at the burners, causing the fuel/air mixture to go rich and also flame roll-out. Just a theory.
Excited for your next masterpiece
Kind of you to say! Stay warm.
Why are you choosing Columbia for the replacement boiler?
In stock at local rep, and reliable delivery.
My my that’s one sorry looking boiler, combustion fumes leaking badly?
Yes, and a hole at the water-line most likely.
What would that boiler have used before spark ignition was added?
It would most likely have been ordinary standing pilot.
@ Thank you for your response to my dumb question- I had stupidly mistaken this boiler for an oil-fired unit.

Is that insulation on the wet return ?
Yes, it appears that is the case.

Thank you, I hope so, too.
I don't think there is a roll-out safety switch on this boiler.
Outside looks a little burned up, what happened?

That makes sense.👍
Demo'd it today.
It seemed like it mostly all rust held together (barely) with soot lol.
