Utica-Dunkirk 240012905 Orifice
The Utica-Dunkirk 240012905 Orifice is a high-precision Main Burner Orifice specifically engineered for natural gas burner systems. This OEM component, designated as a #34 orifice, is critical for achieving the stoichiometric air-fuel ratio required for efficient combustion and peak thermal output. Designed primarily for Dunkirk XEB Series II (3-5 Section) and WPSB Series boilers, this 1-inch long orifice manages manifold pressure delivery to ensure stable flame patterns and reduced carbon monoxide production. For service technicians, utilizing this genuine Utica heating part is essential for maintaining the UL/CSA certification of the equipment and avoiding the performance degradation associated with off-spec aftermarket alternatives. Whether you are performing a seasonal burner cleaning or a full manifold rebuild, the 240012905 provides the exact flow rate required to match the BTU input ratings found on the boiler’s data plate, ensuring reliable ignition and consistent operation in demanding residential and commercial hydronic applications.
Key Benefits- Precise Flow Regulation: Specifically sized as a #34 orifice to maintain exact BTU input for Dunkirk XEB Series II 3, 4, and 5 section boilers.
- High-Grade Construction: Manufactured from corrosion-resistant metal to withstand high-temperature burner environments without port degradation.
- OEM Compatibility: Replaces legacy part numbers 146-15-031 and 14615031, ensuring a seamless fit in Utica-Dunkirk burner manifolds.
- Optimized Combustion: Engineered to provide the correct gas velocity for efficient mixing with primary air, reducing soot buildup on heat exchanger surfaces.
Is the 240012905 compatible with LP systems?
No, this orifice is specifically for natural gas (N/G). For Liquid Propane conversions, a different orifice size and spring kit must be used to accommodate the higher energy density and pressure of LP.
What is the drill size for this orifice?
This part is a #34 drill size. For accurate field verification, technicians should use a standard orifice drill bit set to confirm the port diameter matches manufacturer specifications.
Which boiler models use this part?
It is primarily utilized in Dunkirk XEB-3, XEB-4, and XEB-5 Series II boilers and WPSB Series hydronic systems. Always check the section count of the boiler as the manifold requires one less orifice than the total number of sections.
