ABSTRACT:
A furnace heat exchanger and support plate assembly are joined together at respective openings for the burner assembly and for the combustion products outlet by an oval rim defining the heat exchanger opening and a cooperating flange on a partition plate and extending perpendicular to the plane of the plate. The flange on the partition plate is inserted in the opening in the heat exchanger unit and expanded radially outward with respect to the central longitudinal axis of the openings to form a leakproof joint. An improved method of forming the joint includes the use of an expander mechanism which may be inserted through the opening in the plate into the interior of the heat exchanger and engaged with the plate flange to expand the flange radially outwardly. A complete nonwelded furnace heat exchanger assembly includes one or more support members which are secured to flanges of the heat exchanger units without welding or mechanical fasteners.
