Erby Posted April 17, 2014 Report Share Posted April 17, 2014 Anyone want to take a stab at it. I'm guessing 83 From the furnace age chart: Click to Enlarge 17.1 KB Click to Enlarge 36.91 KB Click to Enlarge 66.75 KB Link to comment Share on other sites More sharing options...
AHI in AR Posted April 18, 2014 Report Share Posted April 18, 2014 I can't tell much from the overall photo but GE sold out to Trane in the 80's. My guess is somewhere in the mid 80's based on what I can see. Was there an ANSI date? It was a pilot light unit, right? What's the age of the home?

Erby Posted April 18, 2014 Author Report Share Posted April 18, 2014 You have the whole data plate, no ANSI Date. Yes, pilot light. 50 plus on age of home. Link to comment Share on other sites More sharing options...
AHI in AR Posted April 18, 2014 Report Share Posted April 18, 2014 Then if the last 3 digits of SN are 304 as they appear to me I would think that '83 is correct also. Definitely an older style unit. (And by "overall photo" I meant the unit itself, not the tag.) Link to comment Share on other sites More sharing options...
Bill Kibbel Posted April 18, 2014 Report Share Posted April 18, 2014 I'd bet that furnace was manufactured before the date code made it into GE serial numbers. It really looks like 1960's. Separate manual B-valve for the pilot feed, right? Link to comment Share on other sites More sharing options...
kurt Posted April 18, 2014 Report Share Posted April 18, 2014 No ANSI # means pre-1976, doesn't it? I'd say late 60's, early 70's. Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted April 18, 2014 Report Share Posted April 18, 2014 I agree w/ the educated guess of the 60's era. Link to comment Share on other sites More sharing options...
inspector57 Posted April 18, 2014 Report Share Posted April 18, 2014 Definitely older than the 80's. I'm betting original to the house, 60's or 70's. Link to comment Share on other sites More sharing options...
Erby Posted April 18, 2014 Author Report Share Posted April 18, 2014 Given the house was built in 1963, I'd tend to agree with Bill and Kurt and Jim. Didn't know about the ANSI dates starting in 1976. You can learn so dang much here. A wonderful resource to have in the back pocket! Link to comment Share on other sites More sharing options...
kurt Posted April 18, 2014 Report Share Posted April 18, 2014 I think it's 1976, maybe a little earlier. I've never read a definitive statement to that effect; I sort of figured it out back in the 80's when I noticed the new stuff had ANSI dates, and the old stuff didn't. I narrowed it down to (approximately) 1976 on my own. Anyone know for sure? I've googled it but didn't find anything. Link to comment Share on other sites More sharing options...
mjr6550 Posted April 21, 2014 Report Share Posted April 21, 2014 Looks like an oldie. How old is the house? Later GE furnaces have a 9 digit SN and the third from the end in the last digit of the year. The 9 digits are all run together. If that used a similar code then 1973, 1963, 1953 could be possibilities. Its hard to see details in that photo, but 1973 seems too new. The MN does not match anything in the 1967 to 1993 Carrier Blue Book, so earlier than that is likely. I'm not looking at the photo now, but I think under gas type is said OPT-NAT. Optional? Could be from the transition period from mixed or manufactured gas (1950s-60s at the late end). Link to comment Share on other sites More sharing options...
Erby Posted April 21, 2014 Author Report Share Posted April 21, 2014 Mark, I think we've all pretty much settled on it being original to the house, built in 1963. Other issues drove the buyer away though, so it's a cancelled contract. Link to comment Share on other sites More sharing options...
