Magic Chef Furnace Date?

[Greg Booth]

Hello.........looking for manufacture date of: Magic Chef, Oil Furnace, Model- L6A84D-1, SN A11891GHB. Home built circa 1987.

Thanks for any help..............Greg

My Preston's Guide dates the furnace anywhere between 1985-1988. You can pretty much bet that it is original to the home at 1987.

Thanks very much.............Greg

All have one letter, five numbers, then three letters.

Last three letters are Date and Place of Manufacturer. First letter is the month, middle is year. year codes are: A = 1980, B = 1981, C = 1982 and so on until 1998. So yes this one is H = 1987.
