It provides a telescoping length range of 3.5 to 10.5 inches at a 7-inch diameter, making it a practical solution for closing gaps between fixed-length vent sections during installation or retrofit work. Licensed HVAC technicians and plumbers install this type of fitting when a standard fixed-length pipe section does not align precisely with existing vent runs or appliance collar connections. The adjustable design eliminates field cutting and reduces the chance of improper fitment in tight mechanical chases.\u003c\/p\u003e\n\u003cp\u003eThis pipe section is suited for residential and light commercial gas appliance venting applications where Type B double-wall vent pipe is required. Typical use cases include furnaces, boilers, water heaters, and other natural-draft gas appliances that exhaust through a B-vent system. The adjustable length is particularly useful when connecting an appliance collar to a ceiling support or when bridging minor dimensional mismatches in a multi-section vertical or horizontal vent assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable length from 3.5 to 10.5 inches to accommodate variable spacing in vent runs\u003c\/li\u003e\n  \u003cli\u003e7-inch diameter matches standard B-vent system sizing for natural-draft gas appliances\u003c\/li\u003e\n  \u003cli\u003eRound pipe profile for consistent airflow and straightforward connection to other B-vent fittings\u003c\/li\u003e\n  \u003cli\u003eTelescoping construction allows on-the-spot length adjustment without field cutting\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in Type B double-wall gas vent systems per applicable venting codes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style adjustable section for use within 7-inch Type B double-wall gas vent systems on natural-draft residential and light commercial gas appliances.\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 International Fuel Gas Code (IFGC) and the appliance manufacturer's venting instructions. Shut off and lock out the gas supply to the appliance before disturbing any vent section. Ensure all vent joints are properly secured and that the assembled system maintains the required clearances to combustibles as specified by the vent system manufacturer and local code. Do not use this fitting in applications requiring Type L or Category III or IV positive-pressure vent systems.\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\u003eAdjustable Length Range\u003c\/strong\u003e: 3.5 to 10.5 inches\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\u003eProfile\u003c\/strong\u003e: Round\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: 0712ADJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51347418513714,"sku":"0712ADJ","price":42.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555444.jpg?v=1782104330","url":"https:\/\/voomisupply.com\/products\/duravent-0712adj-b-vent-adjustable-vent-pipe-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
