Utica-Dunkirk 3342701 Burner

The Utica-Dunkirk 3342701 Burner Assembly is a precision-engineered OEM replacement burner specifically designed for PEG-C series gas boilers. This critical combustion component features an integrated pilot bracket and air shutter, facilitating immediate restoration of factory-spec air-fuel ratios and flame stability. Constructed from heavy-duty materials to withstand high thermal stress, the 3342701 burner ensures consistent ignition and prevents the common "delayed ignition" issues found in degraded assemblies. By utilizing a direct-fit burner replacement, technicians can maintain the original AFUE rating of the appliance while ensuring safe venting and CO levels. Whether you are servicing Utica boilers or Dunkirk heating systems, this assembly provides the exact geometry required for proper secondary air entrainment and heat exchanger alignment.

Key Benefits:

• Optimized Combustion: Factory-set pilot bracket positioning ensures precise flame-to-sensor alignment for consistent ignition cycles.
• System Compatibility: Engineered specifically for Utica-Dunkirk PEG-C units, eliminating the need for field modifications.
• Integrated Air Shutter: Allows for fine-tuning of the primary air intake to achieve a clean, blue flame across various gas pressures.
• Durable Construction: Built to resist oxidative scaling and warping under continuous thermal cycling.

Frequently Asked Questions:

Is the 3342701 burner compatible with propane (LP) systems?
This burner assembly is typically configured for natural gas; however, compatibility depends on the orifice size installed. Always verify the orifice BTU rating against the manufacturer's manifold pressure requirements for LP conversions.

Does this assembly include the pilot burner?
The Utica-Dunkirk 3342701 includes the pilot bracket and shutter, but the pilot burner and thermocouple/igniter are typically sold separately depending on the specific ignition system (electronic vs. standing pilot).

Why should I replace the entire burner rather than just the bracket?
Over time, burner ports can clog or enlarge due to corrosion. Replacing the full 3342701 burner assembly ensures uniform gas distribution and prevents hot spots that can damage the heat exchanger.
