PROBLEM TO BE SOLVED: To provide a combustion controller for oil hot air heater in which convenience is enhanced without sacrifice of the feeling of heating by roughly indicating the combustible time after detecting oil supply thereby notifying the residual combustion time to a user without causing any trouble. SOLUTION: Residual time up to final indication is set longer than the indicating time after switching but shorter than the indicating time after switching to the final indication. Since a short combustible time can be notified to a user and the user can alter combustion when the heating load is varied due to variation in the condition of working environment after oil supply is detected, the feeling of heating is not damaged and the residual combustion time can be set optimally depending on the working conditions. Convenience is enhanced significantly by notifying the remaining fuel in the tank, and thereby the residual combustion time, to the user through an oil supply detecting/notifying means 23 without causing any trouble.
