Manufactured to Lennox factory tolerances, it restores full heating output and rated efficiency.\u003c\/p\u003e\u003cp\u003eWhen a heat exchanger begins to fail, you may notice visible cracking or rust, an unstable or discolored flame, soot accumulation, unusual smells when the furnace runs, or repeated lockouts on the safety limit control. Since cracks can leak carbon monoxide into the home, this is a component that should be replaced without delay.\u003c\/p\u003e\u003cp\u003eAn OEM \u003cstrong\u003e24W48\u003c\/strong\u003e is the right choice for Lennox systems because it is engineered specifically for the burner spacing, gas input, and airflow characteristics of your furnace.
