Utica-Dunkirk 550003105 Pilot Assembly

The Utica-Dunkirk 550003105 Pilot Assembly is a specialized LP spark pilot assembly designed for high-efficiency liquid propane boiler systems. This critical combustion component serves as the direct replacement for 14662094 and 14662093, ensuring precise ignition sequences and flame rectification in specific Utica, Dunkirk, and ECR International gas-fired boilers. Built to handle the specific BTU requirements and pressure dynamics of propane applications, this intermittent pilot ignition assembly includes the high-voltage electrode, ceramic insulator, and pilot burner. For technicians performing HVAC boiler repair, this OEM part resolves common ignition failures, weak flame signals, and intermittent lockout codes. Utilizing genuine Utica boiler replacement parts ensures the burner's flame sensing circuit maintains the correct microamp signal to the control module. This Dunkirk boiler pilot assembly is engineered for heavy-duty cycling, maintaining proper alignment of the spark gap to prevent delayed ignition and potential combustion flutter.

Key Benefits

• Direct Fit Compatibility: Seamlessly replaces legacy part numbers 14662094 and 14662093 without field modification.
• Propane Optimized: Specific orifice sizing for LP spark pilot assemblies ensures a stable pilot flame.
• Integrated Electrode: High-temperature ceramic insulation prevents voltage leakage during the ignition spark.
• Simplified Service: Pre-configured bracketry allows for rapid installation during emergency service calls.

Common Questions

Can I use this 550003105 assembly for a Natural Gas boiler?
No, this specific assembly is configured as an LP spark pilot assembly. Using it with natural gas will result in improper combustion and potential safety hazards.

What does it mean if my boiler is showing a flame signal error?
If the control module doesn't detect a microamp signal through the flame sensing electrode on the pilot assembly, it will trigger a lockout. Replacing a fouled or cracked pilot assembly often restores consistent operation.

Does this include the ignition wire?
This Utica-Dunkirk 550003105 Pilot Assembly includes the lead wires required to connect the electrode to the ignition control module.
