ABSTRACT:
Instead of constructing an air furnace cabinet as a separate unit and then installing the furnace components such as electrical heating elements, controls and a blower, in the present invention a blower scroll assembly and a heating element assembly are first constructed using flanged sheet metal panels as wide as the interior of the cabinet. The cabinet is then assembled about and integrally reinforced by these assemblies. Lines of securement of the flanges of these assemblies divide the exterior cabinet walls into smaller parts and afford to the cabinet strength and structural rigidity.
