Lennox 56L55 Orifice
The Lennox 56L55 Orifice is a genuine OEM component engineered for precision fuel regulation in high-efficiency gas furnaces and packaged rooftop units converted for liquid propane (LP) gas usage. This #52 LP orifice is critical for maintaining the correct stoichiometry in the burner assembly, ensuring stable combustion and preventing soot accumulation or delayed ignition often caused by improper drill sizes. Whether you are performing a natural gas to propane conversion or replacing a fouled nozzle, this tapered brass orifice provides the exact BTU input required for Lennox HVAC equipment specifications.
Designed for professional contractors, the Lennox 56L55 (Part number 65253800) fits a variety of series, including LG/LD, KG/KD, and ZG/SD models. Technical field verification of the manifold pressure is required after installation to ensure the system operates within the standard 10.0" to 11.0" W.C. range for LP. Utilizing a genuine Lennox replacement part guarantees dimensional accuracy and thread compatibility with the gas manifold, reducing the risk of leaks associated with generic alternatives.
Key Benefits:- Ensures accurate LP gas flow to the burner for optimal thermal efficiency.
- Precision-machined #52 drill size prevents over-firing and heat exchanger stress.
- Direct OEM replacement for Lennox gas furnaces and rooftop units.
- Durable brass construction resists corrosion in high-temperature combustion zones.
- Critical component for safe propane gas conversion and maintenance.
- What is the drill size for the 56L55? This is a standard #52 LP orifice specifically sized for liquid propane applications.
- Is this compatible with natural gas? No, this orifice is restricted to liquid propane (LP) systems only.
- Which Lennox models does this fit? It is commonly used in LG, KG, and ZG series packaged units; always verify your specific model's conversion kit requirements.
