So to preface this, I am trained to remove asbestos soI know what I’m getting into there, but I cant even find a document online for this thing. It’s been decommissioned a long while, but someone in their infinite wisdom filled it with concrete.

Does anyone know what I’m going to find inside? And challenges to look out for? i understand knocking the bolts off and separating layers and know its going to be bitch with concrete involved, but is there anything else id normally be worried about running into? is there asbestos inside as well? never taken one of these apart or any boiler for that matter so this is all new to me.

I converted from oil to natural gas a year ago. The plumber finished most of the job but ghosted when he said he was gonna come back with several guys to take out the old boiler, which is, to say the least the heaviest thing I’ve ever tried to even tilt. I’ve been taking apart as much as I can, and I’m just wondering if this will come apart in sections, and how I would go about prying the sections apart, which seem to be joined by some weird thread in the joints, I’m assuming to allow for a little expansion rather than explosion. Any advice would be greatly appreciated!
