The Lennox 94H80 Burner Orifice is a precision-engineered LP gas conversion component specifically designed for liquid propane heating applications. Featuring a precise .0570 orifice size, this OEM Lennox replacement part is critical for maintaining the correct gas-to-air ratio, ensuring clean combustion and stable flame patterns. As a direct successor to the 94H8001 and LB-83508, this orifice is frequently utilized in Lennox GHR26 series furnaces and various residential heating units requiring exact fuel metering. For contractors performing a furnace LP conversion, using this genuine Lennox 94H80 prevents the over-firing and high-flame issues associated with incorrect aperture sizing. Key Benefits Precise Flow Control: The .0570 inch diameter is factory-drilled to provide high-accuracy fuel delivery for liquid propane systems. OEM Compatibility: Engineered as a direct fit for Lennox 94H80 and Lennox 94H8001 assemblies, ensuring seamless installation in gas manifolds. Combustion Efficiency: Maintains proper manifold pressure and burner performance to prevent soot buildup and inefficient fuel consumption. Durable Brass Construction: Machined from high-quality brass to withstand thermal stress and ensure long-term reliability in residential HVAC equipment. Common Questions Is the 94H80 compatible with natural gas systems? No, this orifice is specifically sized for LP (liquid propane). Using this in a natural gas application will result in significantly reduced heat output due to the smaller aperture required for propane's higher energy density. Can this part replace a generic .0570 orifice? While the physical size may match, this genuine Lennox part ensures the thread pitch and physical dimensions align perfectly with the Lennox gas manifold, preventing leaks and alignment issues. What models does the Lennox 94H80 fit? This part is commonly found in Lennox GHR26Q2-50 and GHR26Q3-100 series units, as well as various furnace models requiring LP conversion kits.
