Reznor 120153 Orifice
The Reznor 120153 Orifice is a precision-engineered #20 burner orifice designed specifically for maintaining consistent gas flow and combustion efficiency in industrial heating systems. As an authentic Reznor replacement part, this 1/2" burner nozzle features a durable steel body with an NPT connection, ensuring a leak-proof seal and long-term reliability under high-thermal stress. For contractors servicing Reznor unit heaters or duct furnaces, replacing a clogged or corroded gas heater orifice is critical for preventing incomplete combustion and soot buildup. This specific #20 drill size orifice is tailored for specific BTU inputs and gas types; always verify your unit's manifold pressure and gas conversion requirements before installation. Using the correct Reznor 120153 ensures that your burner assembly maintains the exact stoichiometric ratio required for peak performance, reducing fuel waste and preventing unnecessary heat exchanger fatigue. This part is a drop-in component for technicians looking to restore factory-spec heating capacity and flame stability.
Key Benefits:
- Precise Gas Metering: The #20 orifice size provides the exact fuel delivery rate required for compatible Reznor heating units.
- Industrial-Grade Construction: Manufactured from high-strength materials to withstand continuous duty cycles in harsh HVACR environments.
- OEM Compatibility: Ensures a perfect fit within the burner manifold, eliminating the risks associated with universal or modified fittings.
- Optimized Combustion: Helps maintain a steady pilot or main burner flame, critical for system safety and emission compliance.
Common Questions:
How do I verify if the Reznor 120153 is the correct size for my heater?
Technicians should check the rating plate of the specific Reznor unit for the required orifice drill size and gas type (Natural Gas or Propane). The #20 marking must match the manufacturer’s technical data for that specific BTU output.
Can this orifice be used for gas conversions?
While the Reznor 120153 Orifice is a standard metering component, gas conversions require a full kit and adjustment of the regulator. Ensure this #20 orifice aligns with the conversion specifications provided in the Reznor service manual.
What are the signs of a failing burner orifice?
Common indicators include yellow-tipped flames, uneven burner ignition, or visible carbon deposits on the burner head, often caused by a partially obstructed or worn gas orifice.
