It seals the point where the B-vent pipe penetrates the roof deck, keeping weather out and maintaining the required clearance around the vent pipe. This flange is rated for flat roofs through low-slope applications up to a 1\/12 pitch. The tall collar design provides added clearance above the roofline, which is important for proper draft and code-compliant termination height. HVAC technicians and plumbers install this component during gas appliance venting rough-in or when replacing a damaged roof flange on an existing B-vent system.\u003c\/p\u003e\u003cp\u003eThis roof flange is used in residential gas appliance venting installations where Type B double-wall vent pipe exits through a flat or near-flat roof. Typical applications include venting natural gas furnaces, boilers, water heaters, and other Category I appliances. The flat-to-1\/12 pitch rating makes it appropriate for roofs with minimal slope. It is sized for 3-inch B-vent pipe diameter and is intended for use within a complete Type B vent system assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned for flat to 1\/12 roof pitch applications\u003c\/li\u003e\n\u003cli\u003eTall collar design supports proper vent termination height\u003c\/li\u003e\n\u003cli\u003eSized for 3-inch Type B double-wall gas vent pipe\u003c\/li\u003e\n\u003cli\u003eSeals roof penetration against weather infiltration\u003c\/li\u003e\n\u003cli\u003eLightweight at 2.40 pounds for easy single-person handling on the roof\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style component for use with 3-inch Type B double-wall gas vent systems on flat to low-slope residential roofs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed HVAC technician or plumber as part of a gas appliance venting system. Shut off the gas supply and allow the appliance to cool before servicing any vent components. The flange must be flashed and sealed to the roof deck in accordance with the International Fuel Gas Code (IFGC) and the vent manufacturer's listing requirements. Do not use this flange on roof pitches steeper than 1\/12 — a pitch-specific flange is required for greater slopes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoof Pitch Rating\u003c\/strong\u003e: Flat to 1\/12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Double-Wall Gas Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.40 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3eft\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51233242054962,"sku":"3EFT","price":55.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307628966.jpg?v=1780095157","url":"https:\/\/voomisupply.com\/products\/hart-cooley-3eft-b-vent-tall-roof-flange-3-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
