I have recently inherited a Gemini Systems inc. Model 5000 wood burning forced air furnace add on which I plan to heat a garage this winter with. I also have a natural gas furnace in the garage which I plan to be my backup for when the fire goes out. The unit has two Honeywell L4064 Fan limit switches. One is 120v which I assume controls the blower motor, the other has had the tab removed for 24v which again, I assume controls the draft motor from the thermostat 24v through the Honeywell Fan Center, model R8239A with the R8222B relay. The wiring is disconnected at so many points that I have no idea what paths are what. I've searched the net but the only thing I can come up with on this is the patent. The patent was dated 1980 so it's fairly old. Is there anyone out there that would have a manual or wiring schematic of this or be able to help me in figuring out how this should be wired?

Thanks
Rich

Rich I have a gemini 5000 in the garage, I just saw the books on it, do you need all the wiring diagrams? Jerry
