Summary:PURPOSE: To achieve a higher safety by stopping a fuel supplying device automat ically by an abnormality detection signal from an overheating preventing device, sent against a rise in temperature at an installation point of the overheating preventing device. CONSTITUTION: When the amount of air supplied runs short and abnormal combustion occurs resulting from the clogging of a filter 8 of a blower 3 for convection or a suction port 5R of a blower 5D for combustion, closure by a curtain or the like, abnormality in a motor 3A of the blower 3 for convection or a motor 5E of the blower 5D for combustion, a flame FX of a burner 5 turns red, being extended. If the flame FX happens to leak at an open part 7 of a combustion cylinder 6, an overheating preventer 14 provided at the central part of a rear part on the top surface of a top part 4B of an air funnel 4 detects a rise in temperature and transmits a signal to a buzzer or a lamp to emit an alarm or generates a warning light while a fuel supplying device is stopped automatically. This enables checking of a danger of overheating the body 1, coming-out of the flame FX out of a hot air blowoff port 2 or increase of the generation of carbon monoxide.
