Utica Boiler Manufacture Date

Looking to find some insight into the age of this boiler. Different sites that I have found are not matching the serial# style that is on the data plate. Serial is sort of hard to read in the picture attached. Any thoughts on the year of manufacturing would be appreciated.

Serial: 1-735 may be off on the serial number. Faded tag. Definitely 4 characters long.
Model: PEG3009
ANZ Z21.13 is on the tag if this helps.


Thank you for the help.

Yeah sure, nice to get the date.
But more important to say that it could last forever, but also puts much of the gas heat up the chimney (40% or more)

I understand your point. I have seen 60 year old boilers still operating. Operating but how efficiently is a true statement.

Boilers have a significant advantage over forced air. They don’t blow dust from one end of the house to the other. Then you have this:

Junk!
