Does anybody know what the decoding formula is for a Takagi T-K2 Flash Water Heater?  Can't seem to find Takagi products on my regular decoding lists. 

Serial # 15023932.

Also have a what looks to be a pretty old Fraser & Johnston forced air, natural draft furnace that I can't find a decoder for. The numbers seems to be of an earlier era than the Fraser & Johnston decoders that I have found. 

Model # 80 RD 12-A

Code date:  70 F3

Are you trying to figure out the age, or the efficiency?

Hey George,

Trying to figure both, but mostly the age.

I think the place to get your answer is inspectorsjournal.com . The guys there are extremely proficient at equipment dates and other particulars. You will need to register to post, and perhaps introduce yourself, but it's a great site.

please give us a full detail what you like to figure out by this code than we can ans it or you can see the builder in bhopal
