It supports and locates the burner assembly, completes the sealed combustion chamber, and provides the mounting surface that keeps the burners aligned with the heat exchanger inlets. Factory-original dimensions ensure it seats correctly against the existing box top and gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A rusted, cracked, or distorted burner box bottom can allow combustion air leaks, misaligned burners, uneven flame, delayed or noisy ignition, and soot accumulation. Sagging burners, visible corrosion, or a base that no longer holds a tight seal indicate the bottom panel should be replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The burner-to-heat-exchanger alignment is critical for clean, efficient combustion, and aftermarket panels seldom hold Lennox's exact tolerances. Choosing the OEM \u003cstrong\u003e19D14\u003c\/strong\u003e preserves proper burner positioning and enclosure sealing, keeping your Lennox furnace running safely and at rated efficiency.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081130262899,"sku":"LNX-19D14","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-burner-ribbon-LNX-19D14.jpg?v=1783759554","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-burner-box-bottom-19d14","provider":"National HVAC Parts","version":"1.0","type":"link"}
