A flame detection device that uses a breakthrough voltage across a pair of electrodes located in a flame zone to detect the presence of a flame. The flame detection device may be used with a burner that is part of a furnace in a central heating system for a home or building. Unlike conventional flame detection devices that measure ionization current in a flame, the flame detection device detects a flame by determining the voltage required for a spark event across a spark gap located in a flame zone (also referred to as the breakthrough voltage), and evaluating the breakthrough voltage and/or its various characteristics to detect the presence or absence of a flame. According to one example, the flame detection device includes a power supply, an ignition unit, output wires, insulators, and electrodes.
