Therma-Flow Date code

Therma-Flow used to use a month/year or month/day/year system I came across this serial number today - C319C3-14-L. Any ideas??:slight_smile:

FYI - Tech Services at Therma-Flow tells me that the “C” in the serial number is a “0”. The date of my water heater is March 19th, 2003. Hope this helps.
