The Rinnai Flame Rod (805000173) is a genuine OEM replacement sensing component for i-Series Plus combination boilers. The flame rod detects the presence of the burner flame through flame rectification, sending a signal to the control board to confirm combustion is occurring. If the flame rod fails or becomes contaminated with buildup, the boiler may shut down on a lockout fault even when a flame is present. Replace with this OEM flame rod to restore reliable flame sensing and eliminate false lockouts.
