Date code For Armstrong Furnace

[Kenneth R. Malone]

Does anyone have a Date code chart for Armstrong Furnaces? I have one for the Armstrong A/C but not for the furnaces.
Model: GUJ125D20
Serial: 8499F63244

Thanks, Ken

Newer units – (Serial Number) First two numbers equal manufacturing plant #, 2nd two are year and letter in fifth slot is month (A thru M minus I). So 5898 G 07568 would be Plant # 58, Year of MFR would be 1998 and month would be July.

June 1999.
