I need a wiring schematic for a Peerless LUH 75 unit heater. I have read several other threads on this forum asking the same question, but I haven't found the answer. I have already tried the library of Google and cannot find a manual or factory schematic for my unit. The wiring inside the unit is intact, but the j-box wiring was completely undone. My unit has a single speed fan for the unit and a 24v transformer mounted to the cover of the j-box. The attached picture is the inside of the unit. I do not have a picture of the gas valve , but it's wiring looks intact. What I need to know is what the large red, yellow, black wires attach to inside my j-box. Any help would be appreciated.
