Reznor 204611 Electrode Assembly

The Reznor 204611 Electrode Assembly is a crucial OEM replacement part designed for Direct Spark Ignition (DSI) systems. This technical component is engineered specifically for Reznor VR models and UDAP series unit heaters, providing the precise high-voltage arc necessary for reliable burner ignition. Utilizing a robust ceramic insulator and temperature-resistant electrode tip, this assembly ensures consistent performance in high-demand commercial and industrial heating environments.

For field technicians, the 204611 electrode is a direct-fit solution that eliminates common HVAC ignition failure issues such as carbon fouling or cracked insulators. Proper gap alignment and secure mounting are essential for maintaining burner efficiency and preventing lockout scenarios. By replacing worn or corroded electrodes with this genuine Reznor part, contractors can restore the integrity of the heating cycle and ensure long-term operational stability in Reznor unit heaters.

Key Benefits:

• Precise DSI Performance: Engineered for Direct Spark Ignition systems to provide reliable, repeatable arcs for burner startup.
• High-Temperature Durability: Constructed with materials designed to withstand the thermal stresses found in gas-fired heating units.
• OEM Compatibility: A genuine Reznor 204611 component, ensuring exact dimensional fit and electrical characteristics for VR and UDAP series.
• Reduced Service Callbacks: Replaces brittle or failing assemblies to prevent intermittent ignition issues and nuisance system lockouts.

Common Questions:

What are the signs that a Reznor electrode assembly needs replacement?
Technicians should look for visible cracks in the ceramic insulator, excessive carbon buildup on the tip, or a weak, inconsistent spark. These conditions often lead to "ignition failure" fault codes on the DSI control board.

Is this electrode compatible with all Reznor heaters?
The Reznor 204611 is primarily designed for the VR Series (VR50-VR200) and UDAP 150 models. Always verify the part number in the specific heater’s service manual, as electrode geometry varies significantly between unit series.

How do I maintain the 27.22g assembly for optimal performance?
Regularly inspect the electrode during seasonal maintenance. Ensure the gap is set to factory specifications and clean the probe with a non-abrasive material to remove oxidation without damaging the surface integrity.
