ABSTRACT:
A portable forced air heater includes a base, an outer tubular housing mounted on the base which includes front and rear ends, and a burner assembly mounted within the outer housing. The burner assembly includes an inner housing, and support brackets on the inner housing include tabs which extend through slots in the outer housing. A fan is mounted within the outer housing behind the inner housing. The outer housing is provided with an air opening rearwardly of the inner housing, and an air scoop below the air opening guides air from the fan toward the front of the outer housing for cooling the support surface of the heater. An air diffuser plate on the rear end-of the inner housing is provided with radially extending tapered slots which include radially outwardly diverging side edges. The diffuser plate includes a vane for each slot which partially obstructs the slot. A fuel valve is mounted on the base, and a fuel tube extends between the fuel valve and the burner assembly. A replaceable bushing is mounted on the fuel valve for controlling air flow into the fuel tube between the fuel tube and the bushing. Fuel flow through the housing of the fuel valve is varied by a valve body which is reciprocally mounted in a fuel passage in the valve housing. In one position of the valve body fuel can flow only through an opening in the valve body.
