Utica-Dunkirk 3771101 Pilot Assembly
The Utica-Dunkirk 3771101 pilot assembly is a critical OEM replacement component engineered specifically for LP gas systems in residential and commercial boiler configurations. As a direct-fit solution for the ECR International family of brands—including Utica Boilers, Dunkirk, and Pennco—this assembly ensures the precise ignition and consistent flame sensing required to maintain high system efficiency and safe burner operation. Designed for liquid propane applications, the 3771101 integrates seamlessly with existing gas controls and burner mounting brackets, reducing field labor and downtime during boiler service.
For technicians servicing standing pilot or electronic ignition residential boilers, this LP pilot assembly provides the necessary durability to withstand high-temperature combustion environments. Utilizing a Honeywell pilot burner platform (typically cross-referenced with the Q314 series), it features a 1/4 inch compression fitting for secure fuel lines and a calibrated orifice to prevent carboning or lift-off. Replacing a fouled or cracked pilot burner with this genuine 3771101 heater part restores the unit's original factory performance specifications, ensuring reliable HVAC replacement parts are used for safety-critical combustion cycles.
Key Benefits:- OEM Compatibility: Exact drop-in replacement for Utica-Dunkirk, Dunkirk, and Pennco boiler models.
- Calibrated Performance: Specific LP gas orifice ensures the correct BTU input and pilot flame stability.
- Durable Construction: High-grade materials designed for long-term thermal cycling in demanding boiler heat exchangers.
- Simplified Installation: Compact design with standard mounting points facilitates faster replacements in the field.
- Is this assembly compatible with natural gas? No, the 3771101 is specifically jetted and rated for liquid propane (LP). Installing this in a natural gas system will result in improper combustion.
- Does this include the thermocouple or thermopile? This specific SKU is typically the pilot burner assembly itself; check your existing lead for compatibility with standard 30mV or powerpile connections.
- Which boiler models use the 3771101? It is frequently found in Series II, MGB, and USC3-5 boiler series from ECR International brands.
