Thanks Darren.

Turns out it is 1969.

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.?

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?

The World Trade Center opened in 1974.

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.
