    This was a hard one to locate. It appears it falls under a general “Residential Electric Water Heater” owner’s manual which covers many legacy models. I added it to the table above but here’s the Link.

Thanks a lot for all help you’ve provided to people.
I am trying to determine age of my W.H. by American water heater co.
Model# FG6140T403NOV Serial # 0520127619
Could you kindly suggest what would be the replacement Model type for this Gas water heater, 40 Gallons, 40,000 BTU??
Thanks a lot in advance.

  Thanks for commenting. I wish I had the time to respond to every comment on the site but it’s just something I do on the side so time is limited.
  Check out the “How to Determine the Age of a Water Heater” page. In your case, the manufacture date would be the 20th week of 2005.
  As for what the replacement model would be, see our American Water Heaters page for current recommendations but you may simply wish to contact the brand directly: http://www.americanwaterheater.com/contact
