Violent shaking of boiler

johnjpope

So, I'm trying to figure out what could have caused this. I had someone by earlier to replace the flame sensor and igniter for my boiler. Things were working great until about an hour ago when the boiler started shaking like crazy. So hard the house was vibrating. I shut it off, and now the shaking happens almost immediately after it fires now. Does anyone have any idea what could have caused this? It's a Williamson OSB-4 with a with an Economite EC200 conversion burner.

KEEP IT SHUT OFF
are you sure you have water in that boiler?

WAIT,
DO NOT rush down there and add water,
if there's no water, and the boiler has been firing and overheating, then you have a BOMB if you're adding water before the boiler can cool.
Until you can touch the near boiler piping, and control surfaces,
Don't add water unless that boiler is cool.

I intend to leave it off until I can get someone to look at it tomorrow. And I have water in the boiler, at least as far as the indicator glass shows.

is it hotter than hot ?
any new unusual odor ?

I'm honestly not sure if it's hotter or not, as I shut it off too fast. The shaking starts very quickly. Probably less than 10 seconds after the purge cycle. I hadn't really noticed any kind of odor.

keep it off til someone looks at it,

When the repairman came by, he said the knob for the gas valve was loose and probably got knocked when he was taking it in an out. Gas flow is back to normal and house is not shaking.
