Boy that's a challenge! You might be able to figure it out here: http://www.heatinghelp.com/files/articles/940/182.pdf. Beginning on page 12 there are descriptions of American Standard boilers with model numbers. Maybe you will see something that helps you ID the right one.

You could also try here: http://www1.eere.energy.gov/buildings/appliance_standards/residential/pdfs/furnaces_boilers/furnace_boiler_app7_2.pdf. This is a PDF that helps decode model numbers for various boilers. On page 5 there is a chart that should be of help.

Hope this helps. Let us know if you are able to figure it out and how.
