Fenwal 22-100000-555 Ignitor

The Fenwal 22-100000-555 Ignitor is a heavy-duty, commercial-grade spark generator engineered for critical combustion timing in high-efficiency gas-fired equipment. This genuine Fenwal ignition component features an advanced 0.125-inch spark gap design between the high-voltage rod tip and the burner ground, ensuring a consistent arc for rapid fuel ignition. Constructed with glazed Alumina ceramics capable of withstanding operating temperatures up to 2175°F, this HVAC replacement ignitor is built for the demanding environments of condensing furnaces, industrial boilers, and atmospheric heating systems. The 6.3mm lead wire and screw terminal connection provide a secure, low-resistance interface for OEM ignition modules. As a CSA-certified spark electrode, it offers a high-voltage output optimized for mesh burners and technical gas torch applications where precise electrical arcing is required to prevent delayed ignition cycles or system lockouts.

Key Benefits:

• High-Temperature Durability: Alumina ceramic insulator rated for 2175°F (1190°C) ensures longevity in high-heat combustion chambers.
• Optimized Ignition Sequence: Precision-edge rod tips maintain a stable .040" to .125" spark gap for reliable 2000V arcing.
• Broad System Compatibility: Direct replacement for several major industrial models including JE100000, JE100100, and 100017000.
• Simplified Field Service: Standard 6.3mm lead wire and screw terminal design allow for fast, drop-in integration into existing wiring harnesses.
• Enhanced Safety: Built to NEC and UL indoor gas appliance standards to prevent gas leaks through dependable spark generation.

Common Questions:

How do I troubleshoot a weak spark on the Fenwal 22-100000-555?
Check the electrode gap; it should typically be 0.125" ±.03” from sharp edge to sharp edge. Ensure the Alumina ceramic is not cracked, as carbon tracking can bleed off the high voltage before it reaches the tip.

Is this ignitor compatible with modulating-condensing boilers?
Yes, its high-temperature construction is ideal for condensing units, though technicians should always verify the specific spark gap requirements for mesh burners used in modulating equipment.

What causes frequent electrode burnout in industrial applications?
Burnout is usually caused by flame impingement or improper positioning within the burner flame. Ensure the spark gap is at the optimal location for lighting without being subjected to continuous direct flame contact post-ignition.
