Excellent product. Patience is required. Old cabinet can be bent, dirty and need cleaning. Study the wires.....carefully. In my situation, I had to trace each wire (on the old unit), back to its origin. What I initially thought proved to be wrong. Be careful. Take your time. By doing so, I was able to wire the furnace core properly.

The Heater core is a great buy. It saves you money and works fantastic. I highly recommend this product. It is easy to install and slides into original heater frame/box. Gas was located at back instead of front and presented no problem because original frame has a knock out plug to have gas located at the back of box.
