It seals the point where a double-wall B-vent pipe penetrates the roofline, providing a weather-tight transition between the vent pipe and the roof deck. Rated for roofs with a pitch up to 5\/12, this flange is a standard component in residential and light commercial gas appliance venting installations. HVAC technicians and plumbers install this flange when routing furnace, boiler, or water heater exhaust through the roof. At 2.10 pounds, it is lightweight enough for single-person installation.\u003c\/p\u003e\n\u003cp\u003eThis flange is used in natural gas and propane appliance venting systems that use Type B double-wall vent pipe. Typical applications include upflow and horizontal furnaces, atmospheric water heaters, and boilers that require vertical vent termination through the roof. It is suited for residential new construction and replacement venting projects where the roof slope does not exceed a 5\/12 pitch. Licensed HVAC technicians and gas fitters are the primary installers of this component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 6-inch Type B double-wall gas vent pipe\u003c\/li\u003e\n  \u003cli\u003eRated for roof pitches up to 5\/12\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 2.10 pounds for easier single-person handling\u003c\/li\u003e\n  \u003cli\u003eProvides a weather-resistant seal at the roof penetration point\u003c\/li\u003e\n  \u003cli\u003eStandard flange profile for straightforward installation on low- to moderate-slope roofs\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 Type B double-wall gas vent systems on roofs with a pitch up to 5\/12.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or gas fitter in accordance with NFPA 54 and local mechanical codes. Shut off the gas supply and allow the appliance to cool completely before beginning any vent system work. The flange must be flashed and sealed to the roofing material per the manufacturer instructions and local building code requirements to prevent water infiltration. Do not use this flange on roof pitches exceeding 5\/12 without selecting an appropriate steep-pitch flange rated for the actual slope.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Roof Pitch\u003c\/strong\u003e: 5\/12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.10 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Double-Wall Gas Vent\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: HART COOLEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6ef\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51233268957490,"sku":"6EF","price":49.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307632801.jpg?v=1780095781","url":"https:\/\/voomisupply.com\/products\/hart-cooley-6ef-b-vent-roof-flange-6-inch-standard","provider":"Voomi Supply","version":"1.0","type":"link"}
