A combustible fuel burner system includes a burner unit, a power source, and a circuit interrupter unit. The circuit interrupter unit has a switch electrically coupled between the power source and the burner unit. The switch has a closed state, wherein the burner unit receives operational electrical power from the power source. The switch moves from a closed state to an open state and electrically disconnects the device from the power source upon a voltage of the power source falling below an interruption threshold. The switch, when in the open state, moves to the closed state upon the voltage of the power source being above a restoration threshold that is higher than the interruption threshold.
