    Date of Intertherm Furnace

    I was wondering if someone might be help me with the age of the following furnace.


    Model # MGH-055A AC

    Date Code: 800C071-01

    I was sent out to a no heat call and this is the unit I encountered. Got it up and running but just wanted to maybe track down some more information on this style of furnace. It was in an older mobile home that has been converted into a bunk shack in a remote camp. They have several of these furnaces in the many trailers in camp. Just want to do some further reading. So curious about the date code.

    Never saw a date code on intertherms but the serial number has the date in it, 4th and 5th digits are the year and 6th and 7th digits are the month.
