{"product_id":"oem-lennox-inshot-burner-39m87","title":"OEM Lennox Inshot Burner — 39M87","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e39M87\u003c\/strong\u003e is an inshot burner used in Lennox gas furnaces. Inshot burners direct a precisely metered jet of gas and primary air into each heat exchanger tube, where it ignites and burns to transfer heat into the airstream. Correct burner geometry and orifice alignment are essential for a clean blue flame, proper flame carryover between burners, and efficient, complete combustion in your Lennox furnace.\u003c\/p\u003e\u003cp\u003eWhen the \u003cstrong\u003e39M87\u003c\/strong\u003e becomes corroded, cracked, clogged, or misaligned, you may see yellow or lazy flames, delayed ignition, flame rollout, sooting, burner noise, or nuisance flame-sensor and limit-switch lockouts. Damaged burners can also cause uneven heating and reduced efficiency.\u003c\/p\u003e\u003cp\u003eOEM matters because the \u003cstrong\u003e39M87\u003c\/strong\u003e is manufactured to Lennox's exact port, venturi, and mounting specifications. A precisely matched inshot burner maintains the designed air-fuel mixture, ensures reliable ignition and carryover, and protects both efficiency and safety — where generic burners risk improper combustion and carbon monoxide production. Install the factory-correct part to restore safe, even, efficient heating for your Lennox system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081130328435,"sku":"LNX-39M87","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-39M87.jpg?v=1783762199","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-inshot-burner-39m87","provider":"National HVAC Parts","version":"1.0","type":"link"}
