Measuring 3 inches in diameter and 60 inches in length, this pipe maintains flue gas temperature through its double-wall construction, which helps sustain the draft needed for safe venting. The twist-lock connection system simplifies assembly and ensures a secure, gas-tight joint. Licensed HVAC technicians and gas appliance installers work with this pipe during new installations and vent system replacements.\u003c\/p\u003e\n\u003cp\u003eThis pipe section is intended for venting Category I gas appliances — those that operate at non-positive vent static pressure and with flue gases at or above their dew point. Typical applications include natural gas and propane furnaces, boilers, and water heaters routed through interior wall or attic chase runs where longer straight sections are required. The 60-inch length reduces the number of joints needed in a straight run, minimizing potential leak points and simplifying layout.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-wall construction maintains flue gas temperature and safe clearances to combustibles\u003c\/li\u003e\n  \u003cli\u003e3-inch diameter x 60-inch length suits long straight vent runs with fewer joints\u003c\/li\u003e\n  \u003cli\u003eTwist-lock connection system provides a secure, repeatable joint without additional fasteners\u003c\/li\u003e\n  \u003cli\u003eDesigned for Category I gas appliance venting — natural gas and propane\u003c\/li\u003e\n  \u003cli\u003eRound rigid form supports consistent airflow and draft performance through the vent system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation component for Category I gas appliance B-vent systems requiring 3-inch diameter double-wall rigid pipe sections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified HVAC technician or licensed gas appliance installer in accordance with NFPA 54 (National Fuel Gas Code) and local authority having jurisdiction requirements. Shut off the gas supply and allow the appliance to cool completely before servicing or extending any vent system. Follow the appliance manufacturer's venting specifications for maximum vent length, number of elbows, and required clearances to combustibles. Do not mix B-vent components from different manufacturers within the same vent run unless listed and labeled for such use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Length\u003c\/strong\u003e: 60 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Construction\u003c\/strong\u003e: Double Wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Form\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVent Category\u003c\/strong\u003e: Category I (B-Vent)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Twist-Lock\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: DURAVENT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0305PI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51346728223026,"sku":"0305PI","price":78.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553328.jpg?v=1782088605","url":"https:\/\/voomisupply.com\/products\/duravent-0305pi-b-vent-round-rigid-pipe-3x60-in-double-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
