FLAME RECTIFICATION Or FLAME SENSING
heatingcooling.fergusonhvac.comMar 21, 2017 · enveloped in flame. Current flows from the sensor though the burner head to ground. Because the sensor is smaller then the burner head, current flows in one direction. The resulting pulsating dc current is considered rectified. The presence of pulsating dc current tells the integrated control board to continue the heating sequence.
