It provides pre-aligned inshot burners on their support bracket so each flame enters the heat exchanger correctly, with reliable cross-lighting and proper flame carryover from burner to burner.\u003c\/p\u003e\u003cp\u003eA burner assembly that is corroded, blocked, or worn typically causes delayed or noisy ignition, a yellow or lifting flame, soot buildup, reduced heat output, and repeated trips of the flame sensor or high-limit switch. Rust flakes, dust, and insect nests inside the burner ports are frequent causes of an unstable flame and nuisance furnace lockouts.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e18L52\u003c\/strong\u003e matters because the three-burner layout, port sizing, and spacing are engineered to match the manifold orifices and heat exchanger of your specific Lennox model. A mismatched or generic burner set can distort the flame, cause incomplete combustion, and create safety issues. The factory \u003cstrong\u003e18L52\u003c\/strong\u003e assembly restores the intended combustion pattern and keeps your Lennox furnace operating safely and at its rated efficiency.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081127608691,"sku":"LNX-18L52","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-burner-inshot-LNX-18L52.jpg?v=1783762185","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-inshot-burner-assembly-3-burner-619795-03-18l52","provider":"National HVAC Parts","version":"1.0","type":"link"}
