Fenwal 22-100001-068 Electrode Assembly

The Fenwal 22-100001-068 Electrode Assembly is a specialized HVAC ignition component engineered for high-performance gas ignition systems found in commercial combustion applications. This replacement electrode features a durable ceramic insulator and a robust metal probe designed to withstand the high temperatures of the combustion chamber while maintaining precise spark gap tolerances. Specifically designed for use with Fenwal gas burner controls, this assembly ensures reliable flame sensing and consistent ignition cycles, minimizing nuisance lockouts in high-demand environments. As a critical failure point in heavy-duty gas valves and burners, having an exact-spec Fenwal electrode is essential for maintaining furnace efficiency and safety. The assembly is built for high-voltage dielectric strength to prevent carbon tracking and grounding issues. Contractors should verify the physical probe geometry and mounting flange dimensions against the existing burner configuration to ensure optimal flame rectification and seamless integration with the direct spark ignition sequence.

Key Benefits for Contractors:

• Precise Flame Supervision: Engineered for high-accuracy flame rectification signals to the control module.
• High-Temperature Durability: Specialized ceramic insulation prevents electrical leakage in extreme heat.
• OEM Compatibility: Exact replacement for Fenwal series ignition systems to ensure system integrity.
• Quick Installation: Standardized mounting footprint reduces labor time during emergency service calls.
• Enhanced Arc Stability: Optimized probe material ensures a consistent spark for reliable gas ignition.

Common Questions:

What causes a Fenwal electrode to fail?
Failure is typically caused by heavy carbon buildup (sooting), a cracked ceramic insulator leading to ground shorts, or probe erosion that alters the required spark gap distance.

Can this assembly be used for both ignition and flame sensing?
Yes, this local sensing electrode is designed to provide the high-voltage spark and then return the microamp signal for flame verification to the control board.

How do I ensure the best performance from this electrode?
Ensure the probe is positioned correctly within the path of the gas flow and that the spark gap is set to the manufacturer's specified clearance before firing the burner.
