Designed for extending vent runs in Category I gas appliance systems, this pipe section safely exhausts flue gases from naturally drafting appliances such as gas furnaces, boilers, and water heaters. The double wall air-insulated construction maintains flue gas temperature while keeping the outer wall cooler to the touch, supporting proper draft and reducing condensation risk. Installation is accomplished via twist-lock connections, allowing sections to join securely without additional tools in most configurations. HVAC technicians and plumbers working on gas appliance venting systems are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe 0712PI is suited for residential and light commercial gas appliance venting applications where Category I B-vent systems are specified. It functions as a straight pipe extension within a larger vent assembly, used in vertical or near-vertical vent runs. This section is compatible with other DVP series B-vent components and is appropriate for use on gas furnaces, boilers, water heaters, and other Category I appliances that require Type B gas vent material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch diameter and 12-inch length for precise vent run extension\u003c\/li\u003e\n  \u003cli\u003eDouble wall air-insulated construction supports proper flue draft and reduces outer wall temperature\u003c\/li\u003e\n  \u003cli\u003eTwist-lock connection system for secure, tool-minimal assembly\u003c\/li\u003e\n  \u003cli\u003eRated for Category I gas appliance venting applications\u003c\/li\u003e\n  \u003cli\u003eRound rigid pipe design maintains consistent airflow through the vent system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use within Category I Type B gas vent systems.

Shut off the gas supply and allow the appliance to cool completely before servicing or extending an existing vent run. Ensure all twist-lock joints are fully engaged and that the vent system maintains the required clearances to combustibles as specified by the pipe manufacturer and applicable code. Do not use B-vent pipe in applications requiring Category II, III, or IV venting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Double Wall Air-Insulated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Gas Vent (B-Vent)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Category I Gas Appliance Venting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Twist-Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round Rigid Pipe\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: 0712PI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51345807114546,"sku":"0712PI","price":52.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555448.jpg?v=1782063483","url":"https:\/\/voomisupply.com\/products\/duravent-0712pi-b-vent-round-rigid-pipe-7x12-in-double-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
