Duravent 0702PI B-vent Round Rigid Pipe 7x24 Inches

Product Description

The DURAVENT 0702PI is a double wall air-insulated B-vent round rigid pipe section used to extend vent runs in Category I gas appliance systems. Measuring 7 inches in diameter and 24 inches in length, it features a double wall air-insulated construction that maintains safe flue gas temperatures while keeping outer surface temperatures within code-accepted limits. Connections are made via a twist-lock mechanism, allowing sections to join securely without additional fasteners. This pipe is intended for installation by licensed HVAC technicians and plumbers working on gas appliance venting systems.

This pipe section is suited for residential and light commercial Category I gas appliance venting applications, including natural gas furnaces, boilers, and water heaters that require Type B vent. The 7-inch diameter accommodates higher-capacity appliance venting requirements. It is used as a straight run extension and can be combined with compatible elbows, tees, and fittings to complete a full vent system assembly.

Installation Notes

Installation of B-vent pipe sections should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and the International Fuel Gas Code (IFGC). Always shut off the gas supply and allow the system to cool completely before servicing or extending an existing vent run. Ensure all twist-lock joints are fully engaged and that the vent system maintains proper clearances to combustibles as required by local codes.
