Mark P Posted March 15, 2011 Author Report Share Posted March 15, 2011 Thanks Darren. Turns out it is 1969. Link to comment Share on other sites More sharing options...
kurt Posted March 15, 2011 Report Share Posted March 15, 2011 Anytime there's no ANSI number, you know it's gotta be pre-1978. Or, was it 1977? I forget...... Either way, when there's no ANSI #, it's gotta be really old. Anyone remember when ANSI #'s were required? If there is an ANSI #, that usually means the mfg. date is 2 years post ANSI date. I'm having a senior moment; anyone remember the actual dates on ANSI reg's.? Link to comment Share on other sites More sharing options...

I'm having a senior moment; anyone remember the actual dates on ANSI reg's.? I can't find anything on that. However, it seems to me that water heaters are always within a couple of years of their ANSI date, but I've seen furnaces & boilers that were much newer (8 years?) than the ANSI date. In the course of looking for the ANSI information I *did* discover that Underwriter's Laboratories dropped the apostrophe in their name in 1974. Now I just need a mnemonic for 1974 to be able to remember it. What happened in 1974 that I can relate to a dropped apostrophe? - Jim Katen, Oregon Link to comment Share on other sites More sharing options...

kurt Posted March 15, 2011 Report Share Posted March 15, 2011 True. Water heaters are always in there, but I recall a few furnaces that are newer by >2 years than their ANSI date. So, there's a hair in my ointment. I'm sure that ANSI dates on listing plates came in the late 70's, though. Of course, I'm reasonably sure that Ellie isn't a set up also.
