ABSTRACT:
A portable forced air heater includes a one-piece unichassis structure which forms the base and the outer housing of the heater. The outer housing defines an elongated passage having a front end and a back end and which receives a burner assembly. The burner assembly is spaced from the outer housing such that cooling air flows between the combustion chamber of the burner assembly and the outer housing. The burner assembly itself includes the elongated combustion chamber which is shorter than the air passage defined by the outer shell and includes a rear head member which is snapped into place in the inlet end of the combustion chamber. Self-aligning mounting tabs and brackets are formed in both the unichassis and the combustion chamber to significantly reduce the number of parts and to simplify construction.
