Carrier 323269-704 Burner Orifice

The Carrier 323269-704 Burner Orifice is a precision-engineered component specifically designed for LP gas conversion and maintenance in Carrier, Bryant, and Payne gas-fired furnaces. This OEM replacement part is the authoritative successor to the LH32DB201 legacy orifice, ensuring exact BTU output and pressure regulation for high-efficiency heating systems. Proper installation of this liquid propane burner orifice is critical for achieving the correct stoichiometric ratio, preventing incomplete combustion and soot accumulation on the heat exchanger. As a technician-grade component, it maintains the precise orifice drill size required for consistent manifold pressure. Whether you are performing a seasonal tune-up or a full system conversion, utilizing this Carrier furnace orifice ensures the burner assembly operates within design parameters, maintaining the integrity of the flame pattern and ensuring reliable ignition sequences for your residential or commercial clients.

• OEM Compatibility: Designed as the direct functional replacement for the LH32DB201 propane orifice.
• Precision Machining: Ensures accurate gas flow rates for LP furnace conversion kits.
• Durable Construction: High-grade brass material resists thermal stress and corrosion within the burner manifold.
• System Calibration: Maintains factory-spec fire rates to optimize gas furnace efficiency and safety.

Common HVAC Technical Questions

What is the difference between the 323269-704 and the LH32DB201?
The 323269-704 is the updated manufacturer part number that serves as the direct drop-in replacement for the older LH32DB201, meeting all original technical specifications.

Can this orifice be used for natural gas applications?
No, this specific part is calibrated for the higher pressure and density requirements of Liquid Propane (LP) systems. Using it for natural gas will result in improper combustion.

Is this part compatible with high-altitude furnace installations?
Standard LP orifices may require derating for high-altitude installs. Verify your manifold pressure and local elevation requirements against the manufacturer’s charging chart before finalizing installation.
