Each in-shot burner draws in primary air and directs the gas-air mixture for clean, complete combustion, transferring heat efficiently while keeping carbon monoxide production low. Consistent flame geometry is essential for reliable ignition and safe operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e delayed ignition or a rollout \"whoomph\" on start-up, yellow or lazy flames instead of crisp blue, rust, cracking, or corrosion on the burner, soot buildup, or flame-sensor faults causing lockouts. Rust flakes and spider webs clogging the burner venturi are typical reasons a burner needs replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the Lennox \u003cstrong\u003e27K33\u003c\/strong\u003e is manufactured to exact orifice alignment, port sizing, and mounting dimensions so the flame lands correctly in the heat exchanger. Generic burners can misalign the flame, cause hot spots, or fail to seat against the manifold — risking cracked heat exchangers and unsafe combustion. Installing the factory-spec burner guarantees proper fit, rated efficiency, and safe performance in your Lennox equipment.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081142321523,"sku":"LNX-27K33","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-27K33.jpg?v=1783762161","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-in-shot-burner-27k33","provider":"National HVAC Parts","version":"1.0","type":"link"}
