A combustion system, particularly for a fuel burning heater that incorporates a glow plug for initiating combustion and a spark plug for maintaining the combustion. An improved switching arrangement is employed for shutting off the glow plug and initiating the spark plug operation at the appropriate period. This system includes a temperature sensing arrangement that senses the temperature in the combustion chamber by means of a remotely positioned radiantly sensitive switching element. This switching element in effect views the temperature in the combustion chamber through a hollow shaft that drives a fan, which fan circulates the combustion products through the chamber. The sensing element may also be employed for continuing the operation of the fan for a predetermined time period after combustion in the combustion chamber ceases.
