The gasket seals the manifold assembly, preventing combustion gas or water leaks at the manifold interface. Proper sealing at this joint is critical to safe and efficient heater operation. This part is installed by licensed plumbers or HVAC technicians performing routine maintenance, post-repair reassembly, or field service on Takagi tankless units. It is a miscellaneous replacement part intended to restore the original factory fit and seal when the existing gasket is worn, compressed, or damaged.\u003c\/p\u003e\u003cp\u003eThis manifold gasket is a service replacement component used across a wide range of Takagi indoor and outdoor tankless water heater models, covering both natural gas (NG) and liquid propane (LP) configurations. It is applicable to residential and light commercial tankless installations where the manifold gasket requires replacement due to age, heat cycling, or leak detection during inspection. The part is intended for use during unit disassembly and reassembly in the field or shop service environment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM-style manifold gasket designed to restore factory seal integrity\u003c\/li\u003e\n\u003cli\u003eCompatible with both natural gas and liquid propane Takagi tankless models\u003c\/li\u003e\n\u003cli\u003eCovers a broad range of indoor (IN), outdoor (OS), and direct-vent (DV) unit configurations\u003c\/li\u003e\n\u003cli\u003eType A designation identifies the specific gasket geometry for correct fitment\u003c\/li\u003e\n\u003cli\u003eIntended for professional service and repair of Takagi tankless water heater manifold assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with the following Takagi tankless water heater models: T-H2-OS (NG), T-K3-OS (LP), T-K4-OS (LP), T-KJR2-IN (LP), T-K3 (NG), T-H3J-OS (LP), T-K3-PRO (LP), T-M50-ASME (NG), T-K3-SP (LP), T-D2-OS (LP), T-KJR2-OS (NG), T-D2-IN (LP), T-D2-IN (NG), T-H3J-OS (NG), T-H3M-DV (LP), T-M50 (LP), T-M50-ASME (LP), T-KJR2-OS (LP), T-H3S-DV (LP), TK-540P-PEH (LP), T-H2S-OS (NG), TK-540P-NEH (NG), T-H2-DV (NG), T-K4-IN (NG), T-K4-IN (LP), T-M50 (NG), T-H3J-DV (NG), T-D2-OS (NG), T-K3-SP (NG), T-H3-DV (LP), T-H3-OS (LP), T-H3S-OS (NG), T-H2S-DV (LP), T-H2-DV (LP), T-H2S-DV (NG), T-H3-OS (NG), T-K3-OS (NG), T-K4-OS (NG), T-KJR2-IN (NG), T-H3S-DV (NG), T-K3-PRO (NG), T-H3M-OS (LP), T-H3J-DV (LP), TK-540P-NIH (NG), T-H3M-OS (NG), T-H2S-OS (LP), T-H2-OS (LP), T-H3M-DV (NG), T-H3S-OS (LP), TK-540P-PIH (LP), T-K3 (LP), T-H3-DV (NG).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis part is typically installed by a licensed plumber or qualified HVAC technician. Before beginning any disassembly, shut off the gas supply and cold water inlet to the unit and allow all components to cool to ambient temperature. Follow the manufacturer service documentation for proper manifold disassembly sequence and gasket seating procedures. Inspect the mating manifold surfaces for warping or debris before installing the new gasket to ensure a proper seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Manifold Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Designation\u003c\/strong\u003e: Type A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Replacement Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type Compatibility\u003c\/strong\u003e: Natural Gas (NG) and Liquid Propane (LP)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TAKAGI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100074229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51150801830194,"sku":"100074229","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305987349.jpg?v=1778618159","url":"https:\/\/voomisupply.com\/products\/takagi-100074229-manifold-gasket-type-a-tankless-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
