kurt Posted April 23, 2014 Report Share Posted April 23, 2014 Using all the age charts, I'm coming up with something that doesn't make any sense. A spotlessly clean and in perfect condition Utica boiler that has a SN HG 31588. My chart sez that should be a 1990-91 boiler. Another chart says it's newer. Another chart doesn't list it, but has something for International. I'm thinking it's a 1990 boiler, but it's perfect and clean, something I don't usually see with Uticas. Any clues?

They became ERC International in 1999, so the label may help. On boilers I look at dates on gas valves pressure relief valve, pressure regulating valves, circulator pumps, controls, etc. to confirm age.

Bill Kibbel Posted April 23, 2014 Report Share Posted April 23, 2014 I have a recent chart from Utica that sez it has to be '90. Date inked on combo gas valve? Date stamped on PRV lever? Quote Link to comment Share on other sites More sharing options...
