Fenwal 22-100000-673 Ignitor

The Fenwal 22-100000-673 Ignitor is a high-performance spark ignition electrode designed for reliability in demanding gas-fired HVACR systems. Built to withstand extreme thermal stress, this component features premium glazed alumina ceramic insulation and specialized rod materials capable of operating in environments up to 2175°F (1190°C). As an OEM Fenwal replacement part, it ensures precise spark gap maintenance, typically at 0.125 inches, which is critical for preventing delayed ignition and ensuring consistent burner light-off in residential and commercial furnaces, boilers, and industrial process heaters. The direct spark ignition design provides a high-voltage discharge necessary for efficient combustion across a wide range of operating conditions. Contractors can rely on this gas ignition component for its exact fit and robust construction, reducing equipment downtime and service call-backs. This HVAC furnace ignitor is also RoHS compliant and CSA certified, meeting stringent industry safety and performance standards for modern high-efficiency and modulating appliances.

Key Benefits

• High-Temperature Durability: Constructed with glazed alumina ceramics and certified alloys rated for high-heat industrial applications.
• Consistent Spark Performance: Designed to maintain a precise spark gap for reliable ignition in both standard and high-efficiency gas burners.
• Universal OEM Compatibility: Serves as a direct-fit Fenwal ignition part for a broad spectrum of commercial and residential gas-fired equipment.
• Regulatory Compliance: Fully CSA certified and RoHS compliant, ensuring the part meets modern environmental and safety engineering specifications.

Common Questions

What causes a Fenwal 22-100000-673 ignitor to fail?
Common failure points include cracked ceramic insulation due to physical impact or extreme thermal cycling, and carbon soot buildup on the rod tip which can insulate the spark. Routine inspection of the spark ignition electrode during seasonal maintenance is recommended.

Can this ignitor be used in modulating-condensing boilers?
Yes, though these high-efficiency systems often utilize mesh burners that may requires specific spark gap adjustments. Always verify the manufacturer's technical specifications for the direct spark ignition distance before final installation.

Is this a universal hot surface ignitor?
No, the 22-100000-673 is a spark electrode, not a hot surface ignitor. It requires a high-voltage ignition module to generate a spark rather than a heating element that glows.
