Abstract: PROBLEM TO BE SOLVED: To shorten the waiting time for operation resumption when a combustion warm air furnace is shut off by mistake. SOLUTION: In a vaporizer of the furnace, the vaporizer is full of gasifiable kerosene during the time period when the temperature of the vaporizer is in the range from a lower-limit temperature Tig (218 deg.C) for start of ignition to an upper limit temperature Thk (266 deg.pC) for start of ignition. Taking notice of this respect, the time period from the start of a pump operation to a nozzle release, that is, the time when the nozzle keeps its closure after the start of pump operation is set shorter than the value set when the vaporizer temperature is rising to the lower-limit temperature Tig (218 deg.C) for start of ignition, and a stable combustion is quickly started under the condition for positively evading an occurrence of an explosive ignition. Thus a waiting time until the warm wind is let out is shortened and the convenience of the space heater is improved.
