Sears Wall Heater Age


Recommended Posts


I have a very very old wall furnace that I am trying to figure out the age of. It's from Sears, model # is 867.73473 and the serial # is 503063K68. It's a gas unit, gravity exhaust, about 2 feet by 3 feet in size. Thanks!!!


All I can tell you is that it was made by Keepright. The serial number doesn't really fit any decoders that I have.

A wild and unsubstantiated guess would be 1968 based on the K68 in the serial number.

Look at the gas valve and, if there is one, the flexible gas connector. They often have dates on them.
