Utica-Dunkirk 3342801 Burner Tube

The Utica-Dunkirk 3342801 is a high-grade standard burner tube engineered for precise gas-to-air mixture in residential and commercial hydronic systems. As a genuine Utica boiler replacement part, this 19nd-long atmospheric burner is critical for maintaining the stoichiometric balance required for clean combustion and high thermal efficiency. Designed to replace fouled or corroded tubes, the 3342801 burner ensures a stable flame pattern across the heat exchanger, preventing localized hot spots and reducing soot accumulation. Whether you are servicing a Dunkirk gas boiler or a Utica heating unit, this OEM component provides a direct-fit solution that eliminates the alignment issues common with generic alternatives. Its robust metal construction stands up to the intense thermal cycling of modern HVAC heating systems, safeguarding the unit's AFUE rating. Professional contractors rely on this burner tube to restore factory-spec performance and ensure consistent ignition during the heating season.

• OEM Compatibility: Guaranteed fit for specific Utica and Dunkirk boiler models, ensuring no-hassle field installation.
• Combustion Efficiency: Engineered for optimal airflow and gas distribution to maximize fuel economy.
• Durable Construction: Built with corrosion-resistant materials to withstand high-temperature combustion environments.
• Atmospheric Stability: Maintains a consistent flame signal and prevents burner noise or "lifting" during operation.
• Direct Replacement: Simplifies maintenance by matching existing manifold and burner bracket configurations.

Is the 3342801 burner tube compatible with both Natural Gas and Propane setups?
Yes, this tube is designed for standard atmospheric applications, though the specific orifice size in your manifold determines the gas type compatibility.

When should a burner tube be replaced versus cleaned?
If you observe heavy oxidation, scaling, or "cherry-red" hotspots on the tube surface that cannot be brushed away, the structural integrity is compromised and replacement is necessary to prevent CO leakage or delayed ignition.

Does this part include the air shutter?
This specific part is the standard burner tube; if your system requires a pre-installed shutter, verify the assembly part number to ensure all required combustion air adjustments can be made.
