ABSTRACT:
A nozzle includes a body, a substantially rectangular foot, air slots and a flow restrictor. The body directs a stream of hot air into the substantially rectangular foot. The foot has a top and bottom surface that includes air slots. The foot also has an outlet across one end for the air flow. A flow restrictor is positioned in the foot, substantially along the outlet to create a back flow of pressure within the foot. The back flow of air causes an even distribution of air across the foot and out the air slots. Thus, increasing radiant heat across the surfaces of the foot.
