Utica-Dunkirk 550001812 Burner Upgrade Kit

The Utica-Dunkirk 550001812 Burner Upgrade Kit is an essential field-replacement component designed to optimize combustion performance in MGB series boilers. This technical assembly serves as a LP burner upgrade, ensuring the manifold pressure and orifice sizing align with liquid propane specifications. As an authentic OEM replacement part, it addresses common issues related to burner tube obsolescence by providing advanced venturi-style tubes engineered for quieter operation and improved flame stability under demanding field conditions.

For a veteran contractor, this kit facilitates a seamless transition or maintenance cycle for Utica Dunkirk boiler parts, specifically targeting models within the MGB-50 through MGB-250 range. The burner orifice configuration and inclusion of high-temperature gaskets ensure a robust seal at the burner door, preventing gas leakage and maximizing thermal transfer. Utilizing this gas boiler burner kit ensures that the combustion system maintains the specific BTU output required for peak seasonal efficiency without the risk of improper fuel-to-air mixtures common in non-standardized conversions.

• Precise LP Orifice Calibration: Pre-sized components eliminate the need for manual drilling, ensuring accurate manifold pressure.
• Enhanced Venturi Design: Upgraded tubes reduce resonant noise and "chugging" during ignition cycles.
• Direct OEM Compatibility: Engineered as a drop-in replacement for obsolete burner tubes in MGB 50-250 series units.
• Operational Reliability: Specifically optimized for liquid propane to prevent carbon buildup and localized overheating.

Is a new burner door required for this installation?
For MGB 50 through 250 units, these tubes are a direct flat-mount replacement and typically do not require a door modification. However, MGB 300 models may require a specific adapter kit. Check your series build date to verify.

Can this kit be used for natural gas to LP conversions?
Yes, this is a primary component for standard propane conversion procedures, though you must also install the correct red-spring regulator kit and pilot orifice to complete the transition.

What are the symptoms of a failing burner tube assembly?
Look for uneven flame patterns, significant soot accumulation on the heat exchanger, or delayed ignition. These often indicate compromised venturi performance or orifice blockage.
