COMBUSTION CONTROL DEVICE FOR HEATER

PURPOSE:To improve the handling property of the quantity of a combustor and maintainability by controlling the variation of the combustion quantity of the combustor of which the combustion quantity always changes due to the variation of a room temperature. CONSTITUTION:A combustion quantity variable means 3 which determines the combustion quantity of a burner 4 by comparing the temperature data of a room temperature setting means 2 and a temperature detecting means 1 for a room temperature is provided. Air and fuel which are controlled by an air quantity variable means 5 and fuel flow rate variable means 6 operated by a combustion quantity variable means 3 are fed to a burner 4, and the burner 4 performs a combustion. Also, a combustion quantity holding means 7 which is manually operated is provided, and when the combustion quantity holding means 7 operates, the variation of the flow rates of the air and fuel to be fed to the burner 4 is stopped, and the combustion of the burner 4 is continued by a combustion quantity prior to the operation. Therefore, the maintainability is improved by keeping a fixed combustion quantity without applying effects of the opening/closing of a door or window to the burner 4.
