Duo therm furnace blower in '67 Globetrotter
I have a DuoTherm furnace in my 67 Globetrotter. It works well but it would work better with a blower. There are a couple of sets of wires located on the floor. One pair is dc and the other is ac or possibly associated with the thermostat located in the wall, inside the front part of the upper side cabinet? Does anyone have any info about this furnace, the wiring, or the optional blower?
