Abstract: A damper, normally biased closed, in a flue of a heating system has an arm which is connected by linkage to an armature of a solenoid for opening the damper when a winding of the solenoid is energized by a heating system control. Switch means, engaged by the arm, is interposed between the heating system control and burner facilities of the heating system for preventing operation of the burner facilities when the damper is closed and for allowing operation of the burner facilities when the damper is open.
