This head shapes the fuel-air mixture leaving the nozzle, generating the swirl and flame-retention pattern required for clean, complete combustion in your Lennox oil-fired system. Its cone geometry is specifically calibrated to the 1.00 GPH nozzle flow for stable ignition and efficient burning.\u003c\/p\u003e\u003cp\u003eA combustion head that is worn, cracked, or coated with carbon can cause sooting, hard or delayed starts, flame pulsation, smoky exhaust, and a noticeable drop in efficiency. Continuous heat exposure erodes the cone over time and distorts the flame pattern the burner depends on.\u003c\/p\u003e\u003cp\u003eInstalling the OEM \u003cstrong\u003e36K42\u003c\/strong\u003e guarantees the exact Lennox-engineered fit and 1.00 GPH performance rating. Factory-correct combustion heads protect flame quality, keep emissions in check, and maintain your burner's designed efficiency.
