The model number typically starts with "GM" and includes a series of letters and numbers to indicate the model of the furnace. Note that the model number is not the same thing as the serial number; the serial number is unique. If you cannot access the furnace, check the instruction manual or other documentation that came with the furnace to find the model number.
