It handles both intake and exhaust in a single concentric assembly, with a 3-inch intake and 4-inch exhaust configuration. Accommodates wall thicknesses ranging from 12.0 inches to 18.0 inches. The kit includes a direct vent conversion kit, a 3x4 concentric termination, a universal adaptor, and a 3-in-1 aluminum flex gear clamp. Licensed plumbers and HVAC technicians install this hardware as part of a compliant venting system for sealed-combustion tankless units.\u003c\/p\u003e\n\u003cp\u003eThis termination kit is intended for residential tankless water heater installations requiring concentric direct vent through an exterior wall. The concentric design routes combustion air in and exhaust gases out through a single wall penetration, reducing the number of holes required and simplifying rough-in. It is confirmed for use with the T-KJr2-IN, T-K4-IN, and T-D2-IN tankless water heater models. Typical installations involve new construction or retrofit applications where a single exterior wall penetration is preferred over separate intake and exhaust runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConcentric 3-inch intake and 4-inch exhaust in a single wall termination assembly\u003c\/li\u003e\n  \u003cli\u003eAccommodates wall thicknesses from 12.0 inches to 18.0 inches\u003c\/li\u003e\n  \u003cli\u003eIncludes direct vent conversion kit, concentric termination, universal adaptor, and aluminum flex gear clamp\u003c\/li\u003e\n  \u003cli\u003eSingle wall penetration design reduces rough-in complexity\u003c\/li\u003e\n  \u003cli\u003eCompatible with confirmed AO SMITH tankless model families\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed for use with AO SMITH tankless water heater models T-KJr2-IN, T-K4-IN, and T-D2-IN.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician in accordance with local mechanical codes and the appliance manufacturer's venting instructions. Shut off the water heater and disconnect power or gas supply before beginning any venting work. Verify wall thickness falls within the 12.0-inch to 18.0-inch range before cutting the wall penetration. Follow all applicable International Fuel Gas Code requirements for termination clearances from windows, doors, and other openings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Termination Kit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Concentric Direct Vent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntake Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Thickness Range\u003c\/strong\u003e: 12.0 inches to 18.0 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 100112420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51149480296754,"sku":"100112420","price":774.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305988573.jpg?v=1778594961","url":"https:\/\/voomisupply.com\/products\/ao-smith-100112420-concentric-dv-termination-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
