Measuring 6 inches in diameter and 36 inches in length, this pipe maintains flue gas temperature through its air-insulated annular space between the inner and outer walls, helping meet clearance-to-combustibles requirements. The twist-lock connection system allows for secure, repeatable field assembly. Licensed gas fitters, HVAC technicians, and plumbers install this type of pipe when constructing or extending vertical B-vent systems on natural gas or propane appliances.\u003c\/p\u003e\n\u003cp\u003eThis pipe section is suited for residential and light commercial gas venting applications where Category I, fan-assisted or natural-draft appliances require a listed B-vent assembly. Common installations include furnace flue systems, water heater vents, and boiler stacks that route vertically through conditioned or unconditioned spaces. The 36-inch rigid section works within modular DVP B-vent systems, allowing contractors to achieve required vertical rise heights while maintaining proper draft characteristics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble wall air-insulated construction maintains flue gas temperature for reliable draft\u003c\/li\u003e\n  \u003cli\u003e6-inch diameter x 36-inch length for standard B-vent installations\u003c\/li\u003e\n  \u003cli\u003eTwist-lock connection system for fast, secure field assembly\u003c\/li\u003e\n  \u003cli\u003eListed for Category I gas appliance venting applications\u003c\/li\u003e\n  \u003cli\u003eRound rigid pipe design compatible with modular B-vent system components\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 6-inch diameter rigid pipe sections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician, plumber, or gas fitter in accordance with NFPA 54 and the appliance manufacturer instructions. Shut off the gas supply and allow the appliance to cool completely before servicing or extending any vent system. Verify all twist-lock joints are fully engaged and support spacing, clearances to combustibles, and termination height meet local code requirements. Do not mix B-vent components from different listed systems without confirming listing compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Construction\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: 0603PI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51347343704370,"sku":"0603PI","price":74.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553265.jpg?v=1782102063","url":"https:\/\/voomisupply.com\/products\/duravent-0603pi-b-vent-rigid-pipe-6x36-inches-double-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
