PORTABLE HEATER WITH INTEGRATED CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE: A heater including a generally cylindrical shell defin- ing its housing arranged in a very closely spaced relation to the outer periphery of its combustion chamber assembly and its fan device as it bounds a plenum chamber therebetween. The combustion chamber assembly has its discharge end adjacent the discharge end of the shell. The relative configuration of the outer peripheral surface of the combustion chamber assembly and that of the discharge end portion of the shell creates therebetween a passage through which the fan device, on en- ergization thereof, produces a very high velocity flow of a thin layer of air which, on discharge, is throttled and ab- ruptly and sharply driven into the center of the flow from the assembly. The effect of this is to moderate and influence a relative uniformity of the temperature of the discharge and rapidly project it outwardly of and considerably beyond the heater. A further consequence is the creation of such a head of pressure in the plenum chamber as to produce a greater and more uniform pressured flow of air into and about the com- bustion chamber. The whole provides a heater which for a given size has a heating capacity substantially greater than heretofore. The heater also features an integrated control system giving it an uncluttered interior and insuring, to a significant degree, against failure and malfunction. A pre- ferred housing for the heater is a multi-part shell the form of which eliminates need for intervening gaskets.
