Utica-Dunkirk 240007403 Orifice
Ensuring the correct firing rate in gas-fired systems requires high-precision components, and the Utica-Dunkirk 240007403 Orifice is the trade-standard choice for professional burner manifolds. This 1/8" Brass Orifice features a 2.9mm metric drill size, specifically engineered to provide accurate fuel regulation in high-efficiency Utica gas boilers and Dunkirk heating systems. As a veteran-grade OEM replacement part, it eliminates the performance issues associated with aftermarket "blank" orifices, such as inconsistent gas flow or improper primary air entrainment. The heavy-duty brass construction offers superior corrosion resistance and thermal stability, maintaining the integrity of the orifice diameter under constant operational heat. This part number is essential for service technicians performing 15B, UH15B, and MGB Series burner maintenance, ensuring the manifold pressure translates into the exact BTU output required for safe, high-altitude or sea-level performance. When replacing natural gas orifices, consistent metric sizing across the entire burner rack is critical for balanced heat distribution and peak combustion efficiency.
Key Benefits- Precision-Drilled 2.9mm Diameter: Specifically sized to maintain optimal manifold flow and firing rates for Utica-Dunkirk boilers.
- Corrosion-Resistant Brass Construction: Durable material resists oxidation and wear from combustion byproducts, ensuring a long-lasting service life.
- OEM Compatibility: Replaces part 240007403 and matches metric standards introduced for enhanced firing accuracy in post-2008 units.
- Easy Installation: Standard 1/8" thread allows for rapid field replacement in confined burner compartments and manifolds.
- Can I mix metric and MTD sized orifices in the same burner? While it is not an immediate safety hazard, mixing different orifice types can cause uneven burner performance. It is recommended to replace the full set to ensure a balanced firing rate.
- What units is this orifice compatible with? It is designed for various Utica and Dunkirk gas boilers, including the 15B, UH15B, and MGB series. Always verify the stamping on your existing orifice before installation.
- Is this part suitable for Propane (LP) conversions? No, 240007403 is specifically sized for Natural Gas. Utilizing this diameter for LP without professional recalculation and a proper conversion kit can lead to hazardous operating conditions.
