Viessmann 7819628 Ionisation Electrode 323055-751 the 70562 is a standardThe Viessmann 7819628 Ionisation Electrode is a critical flame sensing component designed for Vitodens 200 series wall mounted gas fired condensing boilers, specifically the WB2 and WB2A series. Operating on the principle of flame rectification, this electrode passes a microamp signal through the flame to the burner control unit. If the ionization current is not detected, the system immediately terminates the gas supply to prevent hazardous unburnt
