It provides a three-way branch connection with a 6-inch main trunk and two 4-inch branch outlets, allowing installers to split or combine flue gas flow within a venting assembly. The adjustable design accommodates angle variation at the branch, making it easier to align with existing vent runs in tight chases or mechanical rooms. HVAC technicians and plumbers use this fitting when routing exhaust from gas-fired appliances through shared or branched venting configurations.\u003c\/p\u003e\n\u003cp\u003eThis wye fitting is suited for residential and light commercial venting applications involving natural gas or propane appliances such as furnaces, water heaters, and boilers. It is installed within the flue system between the appliance collar and the terminal cap, typically in vertical or near-vertical vent runs where a branch connection is required. The adjustable feature reduces the need for additional offset fittings when duct runs are not perfectly plumb.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable branch angle accommodates varying duct alignment without additional offset fittings\u003c\/li\u003e\n  \u003cli\u003e6-inch main trunk with dual 4-inch branch outlets for branched flue configurations\u003c\/li\u003e\n  \u003cli\u003eDesigned for single-wall flue and B-vent venting assemblies on gas-fired appliances\u003c\/li\u003e\n  \u003cli\u003eThree-way wye geometry supports both splitting and combining of flue gas flow\u003c\/li\u003e\n  \u003cli\u003eFits within the Tees and Wyes product family for standard flue system layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 6-inch by 4-inch by 4-inch single-wall flue and B-vent venting systems on gas-fired residential and light commercial appliances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with the International Fuel Gas Code (IFGC) and the appliance manufacturer venting instructions. Shut off the gas supply and allow the appliance to cool completely before disassembling any portion of the flue system. Secure all flue joints with the appropriate sheet metal screws or listed fasteners and verify that flue gases are exhausting correctly after reassembly. Do not use this fitting in positive-pressure or Category III and IV venting systems unless explicitly rated for that application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Trunk Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Outlet Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Branch Outlets\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Adjustable Wye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Flue Venting\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: LUKJAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: rx77040604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51467606982962,"sku":"RX77040604","price":29.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/lukjan-RX77-flow-wye_f0982d1b-bdd7-4a09-a60b-1f65ada778fd.jpg?v=1783907832","url":"https:\/\/voomisupply.com\/products\/lukjan-rx77040604-adjustable-flue-wye-6x4x4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
