Age of Nationaline Boiler

[rschlater]

Need the age of a Nationaline Boiler. All I could find is the model number, and it is 50A604. There was no serial number on the manufacture ID plate. Need help.
Thanks, Bob

I’m absolutely of no use if I don’t have those blasted serial numbers. In those circumstances, though, try to find the ANSI date. That will indicate that the unit was manufactured no earlier than that ANSI date.

…and, typically I find, manufactured within 3 to 5 years after the ANSI date.
