OEM Lennox Oil Burner Arm — 13T96 (100195-09)

The genuine OEM Lennox 13T96 oil burner arm (factory part number 100195-09, series 1813) is a precision-machined component of the oil burner assembly in Lennox oil-fired furnaces and boilers. It positions the electrode and nozzle assembly so fuel is atomized and ignited correctly, delivering a stable, efficient flame across the full firing cycle. Because it is dimensionally matched to Lennox burner housings, it seats cleanly without modification and preserves factory ignition geometry.

Common failure symptoms: If the burner arm is bent, corroded, or worn, you may notice delayed ignition, rough or noisy startups, sooting, an intermittent or pulsing flame, frequent lockouts on the primary control, or a complete failure to light. Misalignment from a damaged arm is a frequent cause of poor combustion and reduced efficiency.

Why OEM matters: Aftermarket arms often vary in electrode spacing and nozzle depth, which throws off the flame pattern and can cause chronic soot buildup or safety lockouts on Lennox equipment. This factory 13T96 part restores exact electrode gap and nozzle position, protecting combustion efficiency and the life of surrounding burner components. Always confirm the part number against your existing arm before installing.
