ABSTRACT:
A portable heating unit having a housing with a carrying handle, the housing including a motor portion, a blower and an air intake. The housing also includes a mounting nose for receiving a hot air delivery barrel which has a double safety wall construction through that area in which flames for heating air will be generated. A gas nozzle assembly is received either at an angle through an opening in the barrel wall or disposed concentrically within the barrel portion for introducing gas into the barrel. The nozzle assembly draws its air supply for combustion either in the back of the nozzle member and independent of the forced air supply or through the rear end of the barrel and an igniter is provided for lighting the gas by spark means. Provision is made for igniting the combustible gas at a location apart from the turbulent forced air flow and, for safety reasons, ignition of the combustible gasses is not possible in the absence of a forced air stream for delivering the generated heat from the barrel of the device.
