After looking at several internet sites I still don't see how to read the year of manufacture on my Payne gas furnace. Model 80FAU-10 ser. no. 16491 Series 4100.
The serial number is a different pattern than I've found by Googling. Any help appreciated. Just bought an old house and want to know if it's so old that I should consider replacement.
