Fenwal 22-100000-514 Electrode Assembly

The Fenwal 22-100000-514 Electrode Assembly is a direct replacement component engineered for reliable spark-to-pilot ignition sequences in commercial and industrial combustion systems. Designed for use with high-precision gas burners and Fenwal ignition modules, this assembly features a high-grade ceramic insulator that prevents voltage leakage or insulation breakdown during high-temperature operations. The stainless steel electrodes are precision-tapered to maintain a consistent spark gap, ensuring a stable arc and reliable flame sensing via the flame rectification principle. Proper alignment within the burner assembly is critical; this part is built to withstand the thermal stress and vibrational harmonics common in heavy-duty boiler and heater applications, reducing nuisance lockouts and ensuring consistent burner sequencing.

Key Technical Benefits

• Corrosion-Resistant Tip: The probe material is optimized for high-heat environments to prevent oxidation and buildup.
• Dielectric Integrity: Premium ceramic insulation ensures the high-voltage pulse reaches the electrode tip without parasitic loss.
• Application Versatility: Direct compatibility with various Fenwal Series controllers used in commercial HVACR equipment.
• Installation Efficiency: Standardized mounting footprint allows for rapid field replacement and combustion tuning.

Common Technical Questions

Does this assembly support flame rectification?
Yes, the 22-100000-514 acts as the primary probe for flame ion detection, sending microamp signals back to the control module once the pilot is established.

What causes premature electrode failure in these units?
Most failures stem from carbon fouling or "sooting" and cracked ceramic insulators caused by improper mounting torque or excessive thermal cycling.

Is the electrode gap adjustable?
While the gap can be fine-tuned, it is factory-set to a specific tolerance. Contractors should verify the burner manufacturer’s specifications before making manual adjustments.
