The Navien 30028036A Flame Rod is a flame-sensing component designed for compatible Navien tankless water heaters. It works by detecting the presence of a burner flame through electrical conductivity, allowing the control system to confirm proper ignition and maintain safe burner operation. When a flame is not detected, the system can shut down the gas supply to help prevent unsafe conditions. This replacement component supports reliable ignition monitoring, safe operation, and consistent hot-water performance. It is ideal for servicing compatible Navien tankless water heaters and restoring dependable burner operation when the original flame rod becomes worn or faulty.
