Need some help here folks
. We just discovered that we had a Coleman 23,000 BTU furnace stashed under all the stuff we pulled from our bus, it is a model 8623-779 with serial #1685393. Seems to be in good condition and all intact, cept for missing the outside vent grill as well as the inside grill. We sure would like to know if this thing works or not and am needing the owners manual or maybe a wiring diagram. Tried searching the net with little to no success any help would be greatly appreciated.
