Abstract: A heat exchange shell of the type used in home furnaces has a convoluted heat exchange section bounded on its bottom and top, respectively, by a combustion chamber and a flue gas collector. Two half shells are welded together along seams which circumscribe the shell generally in a plane which bisects both the flue gas collector and the combustion chamber. The seam in the intermediate heat exchange section, however, is offset slightly from this plane such that the convoluted wall of each half of the shell is always on only one side of the middle of the seam.
