ABSTRACT:
A forced air heater using self-pressurizing fuels such as propane or butane to drive the blower incorporates an overheat dump port to provide an auxiliary exit for the hot air in the event that the normal outlet becomes obstructed. Also included are means for removing condensation from the fuel conduit, for preheating the fuel source, and for continuing to warm the fuel source and fuel conduit to improve operation of the forced air heater in cold environments. The overheat dump port also provides access into the heater for the high voltage conduit of a spark generator for igniting the fuel within the need for insulating the high voltage conduit.
