Utica-Dunkirk 550001939 Ignitor Kit

The Utica-Dunkirk 550001939 Ignitor Kit is a field-critical Direct Spark Ignition (DSI) component engineered specifically for Utica Dunkirk 95M-200 series boilers. As a veteran technician knows, the precision of the spark gap and the integrity of the dielectric strength are paramount for preventing ignition failure codes and ensuring consistent combustion cycles. This OEM-spec kit replaces the high-voltage Dunkirk gas boiler ignitor, addressing common issues like cracked ceramic insulators and carbon fouling that lead to intermittent lockouts. The assembly features a high-grade Worgas application ignitor designed to withstand the thermal stresses of high-efficiency condensing units. By replacing the existing electrode assembly with this comprehensive kit, contractors ensure a gas-tight seal at the burner manifold, maintaining the required differential pressure for optimal boiler operation. This HVAC replacement part is essential for restoring the boiler ignition system to factory performance standards, ensuring cold-weather reliability for residential and light commercial hydronic systems.

• Precise Ignition Geometry: Engineered for the Utica Dunkirk 95M-200, ensuring the spark arcs at the exact stoichiometric point for reliable burner light-off.
• Complete Installation Hardware: Includes the 240007051 ignitor, a Garfoil gasket, and self-tapping screws to prevent combustion gas leaks.
• High-Dielectric Ceramic Insulator: Designed to prevent high-voltage leakage to the chassis even in high-humidity condensing environments.
• Direct OEM Compatibility: Eliminates the risks associated with universal gas furnace ignitors that may not match the direct spark timing or current draw of Dunkirk controls.

Which boiler models are compatible with the 550001939 kit?
This kit is purpose-built for the Utica Dunkirk 95M-200 modulating condensing boiler. Using it in other series without verifying the part number can lead to improper electrode spacing.

Does this kit include the gasket?
Yes, each Utica-Dunkirk 550001939 kit includes a specialized Garfoil ignitor gasket (Part #1250014) to ensure a high-temperature, airtight seal between the ignitor and the burner plate.

What causes a DSI ignitor to fail prematurely?
Most boiler ignitor failures stem from carbon buildup or moisture saturation in the vent system, which can cause the spark to ground out before reaching the burner.
