The Wacker Neuson Electrode is a genuine OEM component designed for the HI110HD D, HI110D, HDR115, HD50, and HI35 indirect and direct-fired air heater series. As a factory-sourced part, it is manufactured to the exact specifications required for reliable ignition in Wacker Neuson heating equipment. This electrode is the correct replacement for all listed heater models and installs directly in place of the original component without modification.
Key Features
- Genuine OEM Ignition Accuracy — Factory-spec electrode geometry ensures consistent spark gap and reliable ignition timing in Wacker Neuson heaters.
- Direct Drop-In Replacement — Engineered to match the original mounting position and connector interface on HI110HD D, HI110D, HDR115, HD50, and HI35 heater models.
- Broad Heater Family Coverage — A single part number covers both indirect-fired (HI-series) and direct-fired radiant (HDR-series) Wacker Neuson heating units.
- Sustained Heat Output — A correctly functioning electrode delivers a strong, consistent spark to ignite the burner; a worn or fouled electrode causes hard starts, misfires, or complete ignition failure that shuts down heat production.
- Fuel System Safety — A properly seated OEM electrode maintains the correct spark position relative to the burner nozzle, reducing the risk of unburned fuel accumulation during ignition attempts.
The electrode is the ignition component responsible for generating the high-voltage spark that ignites the fuel-and-air mixture inside the heater's burner chamber. Without a strong, correctly positioned spark, the burner cannot light reliably — leading to failed start attempts, error lockouts, or unburned fuel collecting in the combustion chamber. Over time, electrode tips erode, develop carbon deposits, or crack, all of which degrade spark quality and should prompt replacement to restore normal heater operation.
