that is the numbers that was on the plate attached to the furnace itself. under serial number was the letter a. that is all. what you see is what was on the plate. thanks for the help in advance!

Did you get those numbers off the rating plate on the furnace? They don't look like the proper model/serial numbers to me unless this is a unit we dont see up here.

I see the model #, what about the serial #? For most units the date code is the first 4 digits of the srial #
