It is built from UV-stabilized polypropylene, specifically PPs-UV material on both the outer and inner components. This construction makes it resistant to sunlight degradation and suitable for exterior wall installations in residential and light commercial applications. The ICWT352 is compatible with 3-inch and 5-inch vent configurations, giving HVAC installers flexibility when working with different appliance sizes and venting layouts. The concentric design combines flue gas exhaust and combustion air intake into a single wall penetration, which simplifies installation and reduces the number of wall openings required. This approach is standard in direct-vent and sealed combustion systems, including high-efficiency condensing boilers, furnaces, and water heaters. The ICWT352 is compatible with InnoFlue concentric vent systems. It can also be used with InnoFlue SW systems when paired with an ICTC adaptor, making it a versatile termination solution across multiple InnoFlue product lines. HVAC technicians installing polypropylene venting for condensing appliances will find this termination straightforward to work with. The black finish blends into a variety of exterior finishes. All components are domestically sourced. Proper wall termination is critical to safe appliance operation. This fitting ensures that exhaust gases are directed away from the structure while fresh combustion air is drawn in cleanly. HVAC professionals working with high-efficiency systems that require Category IV or polypropylene vent materials will recognize the ICWT352 as a reliable, code-compliant termination fitting for concentric vent runs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCompatible with 3-inch and 5-inch InnoFlue concentric vent systems\u003c\/li\u003e\n\u003cli\u003eCombines flue gas exhaust and combustion air intake in a single wall penetration\u003c\/li\u003e\n\u003cli\u003eBuilt from UV-stabilized PPs-UV polypropylene for outdoor durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Centrotherm ICWT352 concentric wall termination simplifies direct-vent installations by combining exhaust and combustion air intake into one fitting.
