Viessmann 7839451 Ionization Electrode W/Gasket

The Viessmann 7839451 Ionization Electrode with Gasket is a flame sensing component used in combustion monitoring in gas-fired boiler part. It is installed in heating units within where flame presence detection is required during burner operation. The electrode operates by generating an ionization signal through contact with the flame, which is interpreted by the control system for ignition verification and operational control. The attached gasket is used at the mounting interface to maintain sealing at the burner connection point. In application, it is fitted inside boiler combustion assemblies as part of the internal safety and control structure in heating equipment.
