Lennox 79L55 Burner Orifice Sintered or fiber-based construction providesThe Lennox 79L55 is a precision engineered #42 burner orifice designed to manage fuel delivery within high efficiency gas furnaces. As a direct replacement for the Lennox 79L5501, this component is critical for maintaining the stoichiometric balance required for clean combustion. This #42 sizing is specifically calibrated to meter gas flow at the manifold, ensuring that the burner assembly receives the exact BTUs required for optimal thermal output
