Fenwal 22-100001-052 Electrode Assembly

The Fenwal 22-100001-052 Electrode Assembly is a specialized ignition electrode designed for precision flame sensing and reliable ignition in high-efficiency gas-fired systems. This heavy-duty HVAC replacement part is engineered to withstand high combustion temperatures while maintaining total signal integrity back to the ignition controller. Featuring a durable ceramic insulator and high-grade Kanthal alloy probe, it provides consistent conductivity for direct spark ignition (DSI) sequences. Common in process heating and commercial atmospheric burners, this assembly is essential for preventing nuisance lockouts and ensuring accurate microamp flame current readings. Its rugged construction resists carbon buildup and thermal fatigue, making it a drop-in solution for technicians addressing intermittent pilot failures or electrode degradation. Rely on this OEM-grade replacement to restore system timing and maintain strict safety standards across diverse burner configurations.

• High-Dielectric Strength: The ceramic insulator prevents voltage leakage, ensuring the spark gap receives full energy for consistent ignition.
• Corrosion Resistance: High-temperature alloy probe resists oxidation and pitting, extending the service intervals in aggressive combustion environments.
• Precise Signal Feedback: Optimized for reliable flame rectification, minimizing false signal losses that lead to diagnostic codes.
• Robust Mounting: Designed for stable positioning within the burner flame envelope to maximize ion capture.

Common Questions

What causes a Fenwal electrode to fail in high-demand systems?
Failure is typically caused by cracked ceramic insulators due to thermal shock or excessive carbon soot accumulation on the probe surface, which redirects the spark or inhibits flame sensing.

Can I clean the electrode instead of replacing it?
While light cleaning with steel wool may temporarily restore a signal, surface pitting or micro-cracks in the ceramic usually necessitate a full replacement to prevent recurring ignition failures.

Is the gap distance adjustable on this assembly?
The electrode is factory-set, but field adjustments should be verified against the specific burner manufacturer's manual to ensure the spark arc is positioned correctly within the gas-air mixture.
