PURPOSE:To secure the safety of the burner by making the operation of a microswitch identical to the operation of an operating switch carrying out the start/stop of the operation of a burner main body, and carrying out the extraction and insertion of a cartridge tank and turning on and off of the operating switch by the same operation. CONSTITUTION:When an operating switch 17 and a microswitch 15 of a cartridge tank 1 are closed, a microcomputer 19 begins to control an AC load group 18 (a burner part 32, an evaporation heater for evaporating kerosene, a solenoid pump for feeding kerosene, an igniter and the like) and an AC load group 21 (a motor 33 for the burner, and an indoor air circulating blast motor 35) and enters into a combustion sequence. On the other hand, when any of the two switches is turned on, the microcomputer 19 stops the AC group 18 and stops the AC load group 21 after operating the same for a predetermined period of time. Thus, the cartridge tank 1 is extracted from the main body of a kerosene fan heater, the combustion is stopped and when the cartridge tank 1 is re-inserted, the operation is resumed automatically. |
