Built with double wall air-insulated construction, the 3DV36 measures 3 inches in diameter and 36 inches in length, providing the flexibility needed to bridge offsets between appliance flue collars and vertical vent runs. Licensed HVAC technicians and gas appliance installers use this connector when routing from furnaces, water heaters, and similar Category I appliances to an existing vent system.\u003c\/p\u003e\u003cp\u003eThis flex connector is suited for residential and light commercial installations where a rigid connector would not accommodate the appliance position or existing vent layout. It fits between the appliance outlet and the main vent run, handling the transition without requiring extensive repositioning of the appliance or vent stack. It is appropriate for Category I gas appliance venting applications requiring a Type B double wall connector.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble wall air-insulated construction maintains flue gas temperature for proper draft\u003c\/li\u003e\n\u003cli\u003e3-inch diameter fits standard Category I appliance flue collars\u003c\/li\u003e\n\u003cli\u003e36-inch length provides reach for offset and angled connections\u003c\/li\u003e\n\u003cli\u003eFlexible design accommodates alignment variations between appliance and vent system\u003c\/li\u003e\n\u003cli\u003eDesigned for Type B vent system installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation connector for Category I gas appliance venting systems using Type B double wall vent pipe.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified gas appliance installer in accordance with the appliance manufacturer instructions and applicable local mechanical codes. Shut off the gas supply and allow the appliance to cool before disconnecting any existing vent components. Verify that the connector diameter matches both the appliance flue collar and the receiving vent pipe before installation. Do not exceed the maximum connector length or offset angle specified by the appliance manufacturer or local code authority.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3 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\u003eVent Category\u003c\/strong\u003e: Category I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B (B-Vent)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3DV36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51346722390322,"sku":"3DV36","price":133.09,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553343.jpg?v=1782088422","url":"https:\/\/voomisupply.com\/products\/duravent-3dv36-b-vent-flex-connector-pipe-3x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
