Fenwal 22-100000-630 Ignitor Sensor

The Fenwal 22-100000-630 Ignitor Sensor is a high-precision combustion component engineered for flame rectification in industrial and commercial gas-fired systems. Designed to interface with direct spark ignition (DSI) modules, this sensor utilizes a glazed alumina ceramic insulator to maintain high dielectric strength and electrical integrity in environments reaching temperatures up to 2100°F. As an essential part of the flame sensing circuit, it provides the necessary feedback to the ignition control, ensuring the gas valve remains energized only when a stable pilot or burner flame is detected.

For technicians performing a Fenwal ignitor replacement, this OEM-grade sensor ensures seamless compatibility with various furnaces, boilers, and water heaters. The flame probe is constructed from durable Kanthal material, offering superior oxidation resistance and thermal conductivity compared to standard aftermarket alternatives. Integrating this HVAC flame sensor into your combustion safety string helps prevent nuisance lockouts and ensures efficient fuel utilization by providing immediate combustion verification. Its 0.14 lb lightweight design and standard mounting footprint facilitate quick field installation in tight burner compartments.

• High-Temperature Durability: Features specialized alumina ceramic insulation rated for extreme thermal stress in heavy-duty burner applications.
• Precise Signal Transmission: Optimizes flame current detection (typically 1.0 μA DC minimum) for reliable communication with the ignition module.
• Corrosion Resistance: The flame rod is engineered to resist carbon buildup and oxidation, extending intervals between required maintenance.
• Broad Compatibility: A drop-in solution for Fenwal 22-100000-630 specifications in rooftop units, industrial ovens, and commercial infrared heaters.

How do I troubleshoot a Fenwal 22-100000-630 sensor for nuisance lockouts?
Lockouts are often caused by carbon soot buildup or a poor ground connection. Clean the flame rod with a non-abrasive pad (like steel wool) and verify that the burner, sensor, and ignition module share a common chassis ground.

What is the proper gap for this ignitor sensor?
The electrode gap should typically be maintained at 0.125 inches (± 0.031 in) unless otherwise specified by the equipment manufacturer. Ensure the ceramic insulator is not directly exposed to the high-intensity flame core.

Can I use this sensor for remote flame sensing?
Yes, this component is designed for both local and remote flame sensing configurations where the sensor is mounted separately from the spark electrode to monitor the main burner flame.
