Reznor 99254 Kit

Successfully transition your natural gas-fired heating equipment to liquid propane with the Reznor 99254 conversion kit. This OEM-certified NAT TO LP KIT is designed for precision fuel regulation and burner performance in specific Reznor unit heaters. As a factory-authorized NG to LP conversion kit, it includes the essential burner orifice, combustion air restrictor plate, and gas valve regulator spring required to maintain proper manifold pressure and safe combustion levels. Replacing these critical components ensures the burner flame remains stable and efficient under the higher BTU density of propane. Professional installation of the Reznor 99254 is required to verify the new gas pressure settings and to adhere to the manufacturer’s combustion specifications. This HVAC conversion kit is a complete solution for contractors performing field fuel transitions on Reznor TR, UDAP, or similar compatible series, ensuring the unit meets factory performance standards after the fuel source change.

• Ensures accurate natural gas to liquid propane conversion for sustained burner efficiency.
• Includes high-precision LP burner orifices and air restrictor plates for optimal oxygen-to-fuel ratios.
• OEM-certified components prevent common combustion issues like soot buildup or flame lifting.
• Maintains manifold pressure integrity when transitioning from NG to LP fuel sources.
• Facilitates compliance with local mechanical codes for field-converted heating units.

What units are compatible with the Reznor 99254 conversion kit?
The 99254 kit is specifically engineered for Reznor gas-fired unit heaters. It is commonly used in TR and UDAP series models, but you must verify the BTUH input and model prefix on the rating plate before installation.

Can I reuse the original NG orifice after installing this kit?
No, the natural gas to LP conversion requires replacing the orifice with the smaller-diameter LP version included in the kit to account for the increased pressure and energy density of propane.

Is a manometer required for the installation of the Reznor 99254?
Yes, technicians must use a manometer to set and verify the proper manifold pressure as specified in the conversion instructions to ensure safe operation.
