ABSTRACT:
A hot air furnace which includes at least one heat exchange unit having at least one mounting flange section defining an opening therein and a plate member having an aperture therein corresponding to at least one of the openings in said heat exchange unit and in alignment therewith with sheet insulating material interposed between said plate member and heat exchange unit by virtue of the said flange being expanded into a plane parallel to that of said plate member to thereby secure the plate member and interposed insulating material in place on said heat exchange unit. A process for securing at least one plate member on at least one heat exchange unit of a hot air furnace including the steps of positioning sheet insulating material between the plate member and a mounting flange defined opening in the heat exchange unit, insertion of said flange through a corresponding opening in the plate member so as to form a sleeve of insulating material on the outer surface of the flange, and deforming the flange to urge same into a plane parallel with the plate member so as to secure said plate and insulating material in place on the heat exchange unit.
