Ive done a little bit of reasearch regarding this model:
The boiler tag says this:
Serial Number - W21 C2H
Standard Sanitary & Dominion Radiator Limited - Which I believe is now American Standard?
Any Inoformation anyone could offer would be great looked on Goggle but I couldny find anything...
THE REASON - this boiler was installed in 1956ish and has had less than $1000 spent on it since the install date
Im looking for parts maybe and possible contact information regarding a company that can tell me more about this boiler model
