Where does exhaust come out? I would like to see picture of the rear side.

The exhaust comes out of the vent elbow in the furnace, which can be rotated to a different position depending on your desired installation type. The owner's manual found in the resources section has a diagram showing where it is located. The installation manual also has images of each side of the furnace that outline all the important entry and exit points, as well as the dimensions of the furnace.

If you have any further questions, please call us and we will be happy to assist you.
