    Default Furnace Age

    Just when I thought I about had the hang of translating these things, I find a new one.
    Need to determine age and BTU's for this unit.
    BDP Co.(Isn't this the same as Bryant?)
    Mod.# 517GN060020
    Ser.# Y4D15223

    Thanks ahead for any replies

    After Bryant became Bryant, Day-Night, Payne the system changed. In the new system the first and second digits of the serial number are the week and the last two are the year (Applies to all BDP).
    Example: 2799xxxxxx = 27th week of 1999.

    With that in mind, this does not appear to be a BDP serial number.

    517G (Fan coil) units were produced from 1983 until around 1989. This IS a correct serial number.

    The serial numbers work like this:
    A-M (minus I, to reduce confusion) indicate January through December in the 1970's.
    N-Z (minus the letter O, again to reduce confusion) indicate January through December in the 1980's
    The number in the second position indicates the year in the decade

    So, you have:
    The Y indicates Nov. of the 1980's
    The "4" indicates 1984. So, you have a nearly 25 year old unit, produced in November of 1984

    The 060 indicates 60K BTu/h, the 020 indicates 2000 CFM

    Hope this helps.

    JS: Yes, it does help. What would help even more is the manufacturers printing the date like the DD/MM/YYYY. Why is that so damned difficult?
