Repurposing a cast iron hot water boiler as a small steam boiler?

Posting this from our new place in Warren RI. Love being on the east coast!

So back home in UT I have one of those customers. Inherited a property and it has the original snow man. Leaking and it’s really time now but she’s just not able to buy a new one.

I have a 8YO or so WM 210 GV gold CI boiler I’d almost give her. It’s hot water. Can’t I just add a LWCO and tap it different? Anyone tried this?
Just a guy running some pipes.

    If the hw boiler also has the correct tappings for steam. In the old days the mfgs made 1 boiler for both steam & water. Now not so much.

    download the spec sheets for hw & steam and compare

    If it doesn't have the right tappings forget it. It may also not be approved as a steam pressure vessel

    It would probably be a fun project to see if it can be done but it could turn into the gift that keeps on giving.

    Don't even think about it. The GV series would never work with steam.
