It secures the electrode and nozzle assembly at the exact position needed for proper fuel atomization and spark ignition, producing a stable and efficient flame on every cycle. Manufactured to Lennox specifications, it drops directly into compatible burner housings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A bent, corroded, or worn burner arm often causes delayed or hard ignition, rough or pulsing combustion, soot buildup, oil smells, poor efficiency, and repeated lockouts on the primary control. Because the arm sets electrode gap and nozzle depth, even minor damage can disrupt the flame pattern.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Aftermarket arms frequently miss Lennox spacing tolerances, resulting in chronic sooting, unstable flames, and safety shutdowns. The factory \u003cstrong\u003e13U27\u003c\/strong\u003e arm re-establishes exact electrode and nozzle geometry to protect combustion efficiency and surrounding components on your Lennox burner.
