Gooz Member Posts: 7
Does anyone know where I can find any info on an American Standard hydronic boiler model #GPM-6 that is about 30 yrs old?

    What I know

    Input 165,000 BTU, output 132,000 BTU, I think

    (80% Combustion efficiency, when new, about 65-70% AFUE)

    If anyone has access to the Beacon Boiler Reference Book, by Industry Publications, Inc., they could look all the info up
