This kit provides a complete venting solution for direct vent and power vent water heaters that require a 2 inch concentric vent configuration. Concentric vent systems route both the intake air and exhaust flue gases through a single termination point, using a pipe-within-a-pipe design. The inner pipe carries hot exhaust gases out of the building while the outer pipe draws fresh combustion air in from outside. This design simplifies installation by reducing the number of wall or roof penetrations needed, saving both time and materials on the job.\u003c\/p\u003e\u003cp\u003eHVAC and plumbing professionals rely on AO Smith OEM vent kits to ensure proper fit, safe combustion, and compliance with installation codes. Using the correct manufacturer-approved concentric vent kit is critical for maintaining the water heater warranty and meeting local building codes. This 100112869 kit is engineered specifically for AO Smith ULCS636 series units, so installers can be confident in the compatibility and performance of the assembly. The 2 inch diameter sizing is matched to the unit output rating and flue requirements specified by the manufacturer.\u003c\/p\u003e\u003cp\u003eProper venting is one of the most important aspects of any gas water heater installation. A correctly installed concentric vent system prevents backdrafting, ensures complete combustion, and protects indoor air quality. This kit includes the components needed to complete the concentric vent termination for a clean and code-compliant installation. It is well suited for residential and light commercial applications where the ULCS636 model is deployed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDesigned specifically for AO Smith ULCS636 water heater models for guaranteed compatibility\u003c\/li\u003e\n\u003cli\u003eConcentric pipe-within-a-pipe design routes intake and exhaust through a single wall or roof penetration\u003c\/li\u003e\n\u003cli\u003e2 inch diameter vent configuration matched to unit flue requirements for safe and efficient operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe AO Smith 100112869 concentric vent kit is an OEM-approved venting solution for ULCS636 series water heaters, providing a 2 inch concentric vent termination that simplifies installation and ensures code-compliant, safe operation.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100112869\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Concentric Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model Series\u003c\/strong\u003e: ULCS636\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Water Heater Venting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AO SMITH","offers":[{"title":"Default Title","offer_id":51121119920434,"sku":"100112869","price":138.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304882645.jpg?v=1777748925","url":"https:\/\/voomisupply.com\/products\/ao-smith-100112869-concentric-vent-kit-ulcs636-2-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
