    That number tells me that the boiler is located somewhere in New Jersey. The number N5082062-07H is the boiler certificate number on file, assigned by the state inspector that is supposed to make sure the system is safe to operate in a public building. Look for a white piece of paper (sometimes in a small 8x10 black frame) that indicates the boiler was inspected at some point and some stickers on the certificate indicating subsequent annual inspections. The certificate will have that number on it.

    There are some changes I would make to your boiler so it operates more efficiently and safely.
    1. To answer your question about the size or rating, I would
    a. Look at the tag where the green oval is. However, that looks to be missing.
    b. The next way to determine the boiler size is to go to the nozzle in the oil burner and measure the fuel pump pressure to determine the firing rate (and hope the last person who replaced that nozzle knew what they were doing and installed the correct one). With the information on the firing rate you can back into the boiler size.


    2. The Red oval is showing a problem with the way that the safety devices are installed. They are all installed on the same pigtail. If that Pigtail gets clogged, as most pigtails eventually do, then all the safety devices that control the burner so the pressure does not get too high will all be ineffective. This video explains the problem in detail.

    3. The Blue oval shows the flame observation opening is missing a cover. That should be corrected before you put that boiler back in service.

    4. The next picture (below) shows that the flue connector pipe is pitched the wrong way. That must be pitched up from the boiler opening the the chimney base at a slope of at least 1” per 10’ feet

    The measurements are the "should be" dimensions not the "as built" dimensions.

    These are only the things that I can see from the photographs you posted. There are probably many more. You will want to make sure the M&M #67 LWCO is operational and perhaps disassemble it to clean the inside before you recommission that relic.

    Where is the boiler located? You can find someone that knows what they are doing here https://heatinghelp.com/find-a-contractor/

    Thanks, I jumped the gun , I was asked if I was interested in replacing with gas, chimney liner and upgrades, most likely do an EDR on rads. I’ll keep you posted when the contractor gets me up there…….

    Looks like it might be a Peerless.

    Columbia Boilers from the 1960's were that color but the dark green top had rounded corners. That is more likely a Peerless from the 1990's

    I might have a chance to go there next week and take a look …… I’ll keep you guys posted ……… is it possible economically feasible to put two smaller ones in, I know it’s steam but just asking, other question is can you have steam fire individually on warmer days ?

    Looks like it might be a Peerless.

    I agree, probably an LC. Measure it up and compare it to the dimensions here:

    and you can tell for sure. But the radiation count is the proper way to size a replacement.

    There are intersting threads on this site about multiple boilers installations.
    Search for "multiple steam boiler" with the search function (little magnifier in the upper right corner).
