hey guys im in the process of building a hanging heater for my garage to hook up to my owb. I found an old furnace with a good fan in it and pulled it out. Im gonna mount a 12x12 inch heat exchanger to the front of it and hopefully it will work. Im wondering what the wiring colors mean coming off the fan. Red (assuming hot wire) White (assuming neutral) and a yellow which i dont have any idea. Any help appreciated and any help on the hooking of a thermoastat to this. Do they make one to plug into the wall then plug the fan to it? Or can i hook a regular one to the fan without having to pull out circuit boards etc. and have to mount them to the fan motor housing.
