摘要：PURPOSE:To perform a safe and proper operating control by generating an alarm signal with a first stage operating controller when the temperature detected by a temperature sensor reaches a specified first set value while a heat exchanger is under operation. CONSTITUTION:When a combustion blower 11 is in full operation, a fuel control valve 12 is in full open, ignition is carried out by an ignitor to start combustion, and combustion is detected, a convection blower 6 is put into full operation and heating operation state is established. The temperature in heating operation state is detected by a temperature sensor 14, and when the output from temperature sensor 14 is lower than the specified first set temperature, the heating operating state is maintained. When it is judged that the output from the temperature sensor 14 in the heating operating state is higher than the first set temperature, a visible and/or audible alarming device 20 flickers at a specified cycle to inform clogging of a filter 5 and suggest need of cleaning the filter 5.
