Reznor 196852 Orifice

The Reznor 196852 is a precision-engineered LP Orifice designed specifically for liquid propane gas conversion and maintenance in high-performance Reznor heating systems. This OEM propane orifice features a #39 brass construction, factory-drilled to a #40 size (0.0980") to ensure the exact manifold pressure and BTUH input required for safe combustion. Built for the rigorous demands of industrial unit heaters like the Reznor UDAP-75 and the UDAS series, this component provides the standardized fuel-to-air ratio necessary to prevent soot accumulation and heat exchanger fatigue caused by improper firing.

As a veteran tech, you know that field-drilling an HVAC burner orifice is a safety risk; using this genuine Reznor replacement part ensures your gas-fired equipment maintains its high-efficiency rating and operational reliability. Whether you are performing a natural gas to LP conversion or replacing a clogged burner port, the Reznor 196852 LP Orifice provides the mechanical consistency needed for professional-grade heating system repair and predictable thermal output.

• Engineered for UDAP and UDAS Systems: Specifically sized for Reznor unit heaters to ensure seamless integration during LP conversion.
• Standardized #39/40 Sizing: Delivers precise liquid propane flow rates, maintaining the 10" w.c. manifold pressure standard.
• Durable Brass Construction: High-quality material resists corrosion and thermal expansion, ensuring long-term safety and efficiency.
• Direct OEM Replacement: Eliminates the guesswork of aftermarket sizing for HVAC technicians and licensed contractors.

Is the Reznor 196852 compatible with natural gas systems?
No, this is a dedicated LP Orifice designed for liquid propane. Using it with natural gas will lead to insufficient heat output and potential equipment damage.

Can I use this orifice for high-altitude installations?
Standard propane orifices may require de-rating for altitudes above 2,000 feet. Always consult the Reznor technical manual for specific altitude adjustment charts.

Does this include the rest of the gas conversion kit?
The 196852 is the individual replacement burner orifice. Complete gas conversion kits typically include additional springs and labels; verify your requirements before installation.
