Inshot burners fire directly into the heat exchanger tubes, drawing in combustion air and projecting a precise flame for high-efficiency heat transfer. This assembly is the combustion heart of your furnace, engineered for a clean and consistent burn.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e Corroded, cracked, or rust-clogged inshot burners can cause noisy or delayed ignition, flame rollout, yellow or lazy flames, sooting, and flame-sensor lockouts that leave you without heat. Flaking rust or blocked burner ports are strong signs the assembly needs to be replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The Lennox \u003cstrong\u003e18L64\u003c\/strong\u003e is manufactured with exact port sizing, throat geometry, and mounting alignment so each burner fires straight into its heat exchanger tube at the correct gas-to-air ratio.
