転を停止する。When the burner 2 is combusted and the convection fan 4 is operated, warm air and combustion air are drawn from the intake port 5 through the filter 6. Then, the hot air exchanges heat with the heat exchanger 3, mixes with the combustion exhaust gas, passes through the hot air flow path, and is blown out as warm air from the blowing lower. Then, the pressure P detected by the pressure detection means 8 is divided into a pressure range P1 to P2 set by the narrow pressure range setting means 9 and a pressure range P3 to P set by the intermediate pressure range setting means 10.
4. The pressure determining means 12 constantly compares the pressure ranges P5 to P6 set by the wide pressure range setting means 11. Then, when P≧P2 or P≦P1, the pressure determining means 12 issues a signal to the alarm means 13, and the alarm means 13 is activated to inform the outside that there is a blockage for 60 days, but operation continues. Next, when P≧P4 or P≦P3, the pressure determining means 12 sends a signal to the operation control means 14 to forcibly reduce the combustion amount. Furthermore, when P≧P6 or P≦P5, the pressure determining means 12 issues a signal to the operation control means 14 to stop the operation.
