The genuine OEM Lennox 17A29 oil burner drives combustion in your Lennox oil-fired furnace, atomizing fuel oil and blending it with the correct volume of air for a stable, efficient flame. Manufactured to Lennox factory tolerances, it fits precisely into compatible oil furnace models and restores the clean, dependable heat your system was designed to deliver.

Symptoms of a worn or failing burner include difficult or delayed startups, a rumbling flame, puffback or smoke at shutdown, soot accumulation, an oily smell around the unit, and higher fuel consumption. Short cycling and inconsistent room temperatures often point to the same culprit.

Installing an OEM Lennox 17A29 ensures the electrode spacing, air settings, and nozzle alignment match Lennox engineering — details generic replacements frequently miss. The result is proper combustion efficiency, safer operation, and protection for surrounding furnace components, all while keeping your equipment warranty intact. In stock and ships same day before 3PM CST.
