Utica-Dunkirk 2272066 Conversion Kit

The Utica-Dunkirk 2272066 LP to Natural Gas Conversion Kit is a field-essential OEM replacement part designed for technicians performing fuel transitions on liquid propane-fired boilers. This conversion kit facilitates the critical shift to natural gas (NG) by providing precision-engineered orifices and regulator components that ensure proper manifold pressure and orifice sizing. As a high-performance HVAC service part, it is compatible with specific ECR International heating platforms, including select Utica Boilers and Dunkirk gas boilers. Utilizing genuine Utica heating parts maintains the unit's original design specifications, preventing the excessive flame height or combustion instability often associated with aftermarket components. In the field, this kit is vital for re-establishing natural gas burner efficiency and achieving clean combustion signals, particularly after a location gains access to municipal gas lines. Each component is manufactured to match factory flow rates, ensuring your boiler conversion meets strict safety and performance standards without compromising the heat exchanger's integrity.

• Ensures accurate manifold pressure calibration for natural gas residential heating systems.
• Includes OEM-grade orifices and spring kits to prevent improper air-fuel ratios and carbon monoxide production.
• Maintains boiler AFUE ratings by adhering to factory-specified gas flow characteristics.
• Facilitates a seamless fuel conversion process to reduce downtime for the homeowner.
• Direct-fit compatibility for Utica-Dunkirk gas valves ensures stable pilot and main burner ignition.

What is the typical manifold pressure for this kit?
Standard natural gas settings usually require a manifold pressure of approximately 3.5” w.c., though technicians should always verify the specific boiler rating plate and 1.6" w.c. to 5.22" w.c. ranges depending on the specific model series.

Can I use this for a natural gas to LP conversion?
No, the 2272066 is specifically for LP to Natural Gas transitions. Reversing the fuel flow requires a different set of orifices and a high-pressure regulator spring kit rated for propane.

Is specialized equipment required for installation?
Yes, veteran contractors must use a calibrated manometer to set the gas valve pressure and a combustion analyzer to confirm safe CO2 and CO levels after the conversion is complete.
