The genuine OEM Lennox 69W87 (factory number 602866-04, supersedes 609702-01) is a complete burner assembly with a .045 orifice, used in Lennox gas furnaces. It delivers a precisely metered air-fuel mixture to the heat exchanger, producing the stable, efficient flame required for correct furnace operation. Built to Lennox factory specifications, the 69W87 maintains the exact orifice sizing and burner geometry your system was designed around.
Common failure symptoms: difficult or delayed ignition, flame rollout, yellow or sooting flames, burner noise, and repeated flame-sense lockouts. Rust, clogged orifices, and thermal warping are common reasons this assembly needs replacement.
Why OEM matters: Orifice size and burner alignment directly control the air-fuel ratio and combustion quality in your Lennox furnace. An incorrect orifice or aftermarket burner can cause incomplete combustion, improper temperature rise, and heat exchanger damage. The OEM 69W87 assembly ensures correct fit, proper gas metering, and safe, efficient operation for your Lennox equipment.
