Stainless steel construction stands up to the acidic condensate produced when flue gases cool below their dew point, extending service life while maintaining the efficient, safe heat transfer that separates combustion byproducts from your home's supply air. This is the exact exchanger specified for your Lennox equipment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e Look for cracks, pinholes, or split seams in the exchanger, flame rollout or a fluttering flame when the blower starts, water pooling or leaking inside the cabinet, corrosion and pitting, soot, or carbon monoxide detector activation. Because condensing exchangers operate under constant moisture exposure, any breach demands immediate replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003e78W83\u003c\/strong\u003e matches Lennox's precise flue-path routing, condensate drainage angles, and stainless alloy specification.
