American Standard Boiler:
Series # 7BNSE J6
Boiler # G29
CarsonDunlop indicates the last 2 digits in the series# indicates the age. The unit in question has only a single digit (6). Based on the condition alone at the time of the inspection, it is obvious the boiler is beyond its designed life. It seems reasonable to assume the boiler is from the 60’s as per CarsonDunlop.
Just curious if anyone has a Carrier book, and if so, does Carrier give any additional info as to age.
