FWIW, I'd be doing this job with permits and inspections, so I know it would at least meet local codes.
FWIW is worth nothing when using local codes and inspections, as local code inspectors are generalists, more knowledgeable about carpentry and masonry than combustion equipment. The instructions in the steam installation manual that comes with the boiler is made by the engineers to save you heartache from banging, failure, and more expense. The installer that says flat out in writing that he'll follow manufacturer's directions to the letter is the better mechanic. He's covering his butt and yours, not engaging in know-it-all. Many plumbers haven't a clue about residential steam system problems.
DEMAND that he follow the manufacturer's instructions IN WRITING and who knows if they'll be equal. If the installer is recommended in the neighborhood because he has SUCCESSFULLY installed replacement STEAM boilers in the neighborhood and you like the jobs he did that you can SEE, he might be a good choice.
The IN7 has 210,000 btuh input.
The PEG-45 has 150,000 input.
A GO-4 has about 175,000 input.
Seemingly, the installers didn't find the same amount of radiation in the same home AND/OR do not know how to estimate the boiler size from the radiation.
