{"product_id":"oem-lennox-burner-box-bottom-19c77","title":"OEM Lennox Burner Box Bottom — 19C77","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e19C77\u003c\/strong\u003e burner box bottom is the base panel of the burner compartment in your Lennox gas furnace. It supports and locates the burner assembly, provides the lower seal of the combustion area, and works with the box top and support brackets to keep the burners squarely aligned with the gas orifices and heat exchanger inlets.\u003c\/p\u003e\u003cp\u003eA rusted, warped, or damaged burner box bottom can cause burners to sag or shift out of position, produce uneven flames or delayed ignition, allow combustion-air leaks, and generate rattles or rollout faults. Deterioration of this base panel undermines both the alignment and the sealed containment that safe, efficient heating depends on.\u003c\/p\u003e\u003cp\u003eOEM matters because \u003cstrong\u003e19C77\u003c\/strong\u003e is fabricated to Lennox's exact shape, gauge, and high-temperature rating, so it seats precisely and holds the burners in their factory-set geometry. Aftermarket panels can misfit and throw off burner spacing. Choose this genuine Lennox base to restore proper burner support and a correctly sealed combustion compartment.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081129771379,"sku":"LNX-19C77","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-19C77.jpg?v=1783759552","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-burner-box-bottom-19c77","provider":"National HVAC Parts","version":"1.0","type":"link"}
