Severn W2 (American Standard) wood/coal furnace

Capetom Member Posts: 7
Hello All,

I'm new to the forum, searching for information on the furnace in the home (1906) we just bought. It's a large cast iron unit supplying hot water to the radiators, the plate on it seems to indicate it is a Severn W2, maybe by American Standard, in 1958. There is also an oil furnace plumbed into the system. Is anyone familiar with the Severn unit or know of a source of info. I'd like to use it if I can, it was used about ten years ago i think and will definitiely need new gasket material between the sections. Any tips are greatly appreciated.


  • The American Standard

    "Severn" Boiler is a wet based cast iron unit. It came in 6 sizes w/ net ratings of 109,500 to 208,500 btus. The sizes are identified by a 2 digit number. The number may be preceeded by O, OB, SC, or WC. A good boiler in its day.

    The sections were sealed w/ boiler putty, not gaskets or rope, as today. Find the correct numbers & we may be able to pin down which size you have.

    Boiler Putty

    Thanks very much for the info. After reading your post I found some info in the Library section as well.

    Is there anything available as far as a guide to recaulking between the seams with boiler putty? Do I have undo the four large bolts that hold the sections together or can the putty be placed with the furnace assembled?

    There's some great reading on this site that will certainly help me in operating my heating system.
