Utica-Dunkirk 550002585 Retrofit Kit

The Utica-Dunkirk 550002585 Spark Pilot Retrofit Kit is a critical engineering solution for field-upgrading ignition systems in MGB Series II and DXL Series II boilers. As a genuine OEM boiler replacement part, this kit transitions legacy pilot assemblies to a more reliable intermittent pilot ignition configuration, effectively reducing fuel waste and eliminating issues associated with standing pilots. This natural gas and propane retrofit includes a 1/8" x 24" pilot tube, a high-grade electronic ignition pilot burners assembly, and a dedicated LP orifice for versatile fuel compatibility. The inclusion of a pilot shield and specialized bracketry ensures the flame sensor maintains a consistent signal to the ignition control module, preventing nuisance lockouts. For technicians servicing Utica MGB or Dunkirk DXL units, this direct-fit gas boiler ignition kit provides all necessary hardware to restore factory-spec timing and sequencing, ensuring the heat exchanger fires reliably under high-demand residential or light commercial conditions.

Key Benefits for Contractors

• Universal Fuel Application: Shipped for Natural Gas but includes the necessary LP conversion orifice for propane-fired equipment.
• Improved Signal Stability: The included pilot bracket assembly and shield protect the spark electrode and sensor from erratic drafts.
• Reduced Callbacks: Using genuine ECR International parts maintains the original listing of the appliance and ensures component longevity.
• Complete Installation Package: Includes secondary components like compression fittings and 1/8" pilot tubing to replace corroded lines.

Common Questions

Does this kit work for Series I boilers?
This specific 550002585 retrofit is engineered for Series II cabinetry and burner trays; physical dimensions or mounting holes may vary on earlier legacy models.

Is an ignition control module included?
No, this is a mechanical spark pilot kit. If the system is not sparking, the S8610U or equivalent intermittent pilot control should be tested separately.

Can I use the old pilot tubing?
It is standard practice to use the 24-inch pilot tubing included in this kit to ensure a leak-free compression fitting seal and proper gas flow volume.
