Measuring 7 inches in diameter and 36 inches in length, this pipe section uses double wall air-insulated construction to maintain flue gas temperature throughout the vent run, which supports proper draft and meets clearance-to-combustibles requirements. It connects via a twist-lock interface for secure, field-efficient assembly. HVAC technicians and plumbers install this pipe as part of natural draft gas venting systems in residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis pipe section is suited for vertical and offset B-vent installations serving Category I gas appliances such as furnaces, boilers, and water heaters that require natural draft venting. The double wall air-insulated design is appropriate for interior vent runs where maintaining flue gas temperature is critical to system draft performance. It is intended for use within a complete DVP B-vent system using compatible fittings, elbows, and terminations of the same diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch diameter and 36-inch length for standard B-vent vent runs\u003c\/li\u003e\n  \u003cli\u003eDouble wall air-insulated construction maintains flue gas temperature and supports natural draft\u003c\/li\u003e\n  \u003cli\u003eTwist-lock connection system allows secure, tool-efficient field assembly\u003c\/li\u003e\n  \u003cli\u003eDesigned for Category I gas appliance venting in residential and light commercial systems\u003c\/li\u003e\n  \u003cli\u003eRound rigid construction provides consistent airflow cross-section throughout the vent section\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style component for use within DVP B-vent systems requiring 7-inch diameter round rigid pipe sections for Category I gas appliance venting.\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 appliance manufacturer instructions, NFPA 54, and local mechanical codes. Shut off the gas supply and allow the appliance to cool completely before servicing or modifying any vent section. Verify that all twist-lock connections are fully engaged and that proper clearances to combustibles are maintained throughout the vent run. Do not mix pipe diameters or vent system types within a single venting assembly.\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: 36 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\u003ePipe Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Type\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: 0703PI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51346203476274,"sku":"0703PI","price":105.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553281.jpg?v=1782073785","url":"https:\/\/voomisupply.com\/products\/duravent-0703pi-b-vent-round-rigid-pipe-7x36-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
