Intertherm water heater

I’m trying to figure out the age of this intertherm water heater. It is made and installed in a pre fab home. I can’t find any info on it. My best guess is 2008, I’ve looked online and other intertherm water heaters go by the 5th and 6th number on the serial#. But those are from 12 digit serial numbers, this is 9 digit. Any help would be much appreciated

My WAG… 2002

Note: This WH was manufactured by State, and likely follows the State coding system (modified)…

July 2002…

Great! Thanks so much, I really appreciate. If only I took my time and read the whole data plate I might have seen that it was manufactured by State. Thanks again have a great weekend
