Reznor 208290 Orifice

The Reznor 208290 Orifice is a precision-engineered gas burner component designed specifically for unit heaters and furnace applications requiring a 3/16 orifice bore. This critical combustion part ensures a consistent flow rate for natural gas and propane burners, maintaining the precise air-to-fuel ratio necessary for optimal thermal efficiency. Built from high-grade brass to withstand high-temperature environments, it prevents nozzle scaling and maintains strict dimensional tolerances over long-term operation. When replacing a Reznor unit heater orifice, technicians must verify the specific BTU rating of the manifold assembly to ensure this 3/16 inch burner orifice matches the original manufacturer specifications. Proper installation of this replacement burner orifice is essential for preventing soot accumulation, ensuring stable pilot ignition, and maintaining the structural integrity of the heat exchanger by avoiding over-firing or under-firing conditions. This HVAC gas orifice is a direct OEM replacement part, engineered for seamless thread compatibility and leak-free performance in commercial and industrial Reznor heating systems.

• Precision-machined 3/16 orifice bore ensures accurate BTU delivery and secondary air mixing.
• Durable brass construction resists corrosion and thermal degradation in high-heat zones.
• Direct OEM fitment for Reznor heating equipment simplifies field replacements and reduces downtime.
• Maintains consistent manifold pressure calibration for safe and efficient fuel combustion.
• Engineered for easy installation within standard burner manifolds and gas valve assemblies.

Is this orifice compatible with both Natural Gas and Liquid Propane systems?
Compatibility depends on the specific BTU requirements and pressure regulator settings of your Reznor unit; always verify the 3/16 inch drill size translates to the correct input rating for your specific fuel type.

How do I identify if the Reznor 208290 is the correct replacement part?
Check the part number stamped on the existing orifice or cross-reference the Reznor replacement parts catalog using your unit’s model and serial number to ensure bore size alignment.

What are the signs of a failing or clogged gas orifice?
Yellow flames, delayed ignition, or uneven heat distribution typically indicate a blockage or wear in the burner orifice, necessitating a thorough inspection or replacement.
