I am not sure all of the charts refer to the ser# as having more numbers and and starting with a letter. I just noticed it has an energy usage tag on it so I am going to google that and se when they started using them, thanks for the response.

Thanks James that was the best source I found but most of the post and other sources refereed to having A letter or more numbers I think the number was 9, the reason I was interested the buyers were told the equipment in the house was about 4 years old including the water heater that has a date of 1983, thanks to all for your help.
