(This serial number was transcribed from an actual furnace during a home inspection).
Using the four digits located after the last letter in the serial number (usually an “F” or “M” located in the center or 8th digit of the serial number) KP30102F52756585 you will find the week and year of manufacture. The first two digits are the week of manufacture and the last two digits are the year. This unit was manufactured in the 52nd week of 1975.

That serial number sequence won’t work, it will put the unit at 1927. The house was built in 1953. The original heater was a floor heater. I’m guessing this unit is 20 to 40 years old. Any other guesses for older units?
That particular model was manufactured in 1970 through 1971.
