The genuine OEM Lennox 83W35 (factory number 253310-01) is an F6 burner head used in Lennox gas furnaces. The burner head shapes and stabilizes the flame as the air-gas mixture ignites, distributing heat evenly into the heat exchanger for efficient, reliable operation. As a factory component, the 83W35 is manufactured to the precise port pattern and flame-carryover design Lennox specifies for consistent ignition.

Common failure symptoms: uneven or lifting flames, delayed ignition, flame rollout, sooting, burner noise, and flame-sensor dropouts. Corrosion, scale buildup, and cracked or eroded burner ports from long-term thermal stress typically call for replacement.

Why OEM matters: Flame stability and correct heat distribution depend on the exact port geometry of the burner head. An aftermarket or mismatched head can produce an unstable flame, incomplete combustion, and uneven heating that stresses the heat exchanger. The OEM 83W35 burner head restores proper flame characteristics, rated efficiency, and safe operation for your Lennox equipment.
