Duravent 3DV60 B-vent Flex Connector Pipe 3x60 in

Product Description

The DURAVENT 3DV60 is a double wall, air-insulated flexible B-vent connector pipe rated for Category I gas appliance venting. Measuring 3 inches in diameter and 60 inches in length, it provides extended flexible routing between a gas appliance outlet and the fixed vent system. The double wall, air-insulated construction maintains flue gas temperature to support proper draft and reduces the risk of condensation within the connector. Licensed HVAC technicians and plumbers install this type of connector where a rigid vent run is not practical or where vibration isolation between the appliance and the vent stack is required.

This connector is suited for residential and light commercial installations using Category I naturally drafted gas appliances such as furnaces, boilers, and water heaters. The 60-inch flexible length accommodates installations where the appliance must be offset from the vertical vent stack or where access space limits the use of rigid vent sections. It is intended for indoor use within the B-vent system run, not as a replacement for listed rigid pipe in long horizontal runs.

Key Features

• 3-inch diameter accommodates standard Category I appliance vent collars
• 60-inch flexible length allows extended or offset connections
• Double wall, air-insulated construction supports draft maintenance and reduces condensation risk
• Flexible design absorbs minor appliance vibration and simplifies routing in tight spaces
• Compatible with Type B gas vent systems per listed installation requirements

Compatibility

Designed as an OEM-style replacement and new-installation connector for Type B gas vent systems used with Category I naturally drafted gas appliances.

Installation Notes

Installation must be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions, NFPA 54 (National Fuel Gas Code), and applicable local codes. Shut off the gas supply and allow the appliance to cool completely before disconnecting or connecting any vent components. Do not exceed the maximum connector length or horizontal run allowed by the appliance listing and local authority having jurisdiction. Secure all joints per the vent system manufacturer requirements and verify draft operation after installation.
