Duravent 0304PI B-vent Round Rigid Pipe 3x48 Inches

Product Description

The DURAVENT 0304PI is a double-wall, air-insulated B-vent rigid pipe section built for gas appliance venting systems. It measures 3 inches in diameter and 48 inches in length, making it well suited for longer vent runs where a single pipe section needs to cover significant vertical or horizontal distance. The double-wall air-insulated construction maintains flue gas temperature while keeping outer surface temperatures within safe limits. Twist-lock connections secure sections together without fasteners, keeping installation straightforward for HVAC technicians and gas appliance installers working on Category I venting systems.

This pipe section is used in residential and light commercial Category I gas appliance venting applications, including natural gas furnaces, boilers, and water heaters that require B-vent exhaust systems. The 48-inch section length reduces the number of joints needed on long vertical or near-vertical runs, which simplifies the installation and minimizes potential leak points in the vent assembly. It is installed by licensed HVAC technicians and plumbers working on vented gas appliance systems.

Key Features

• Double-wall air-insulated construction for safe flue gas exhaust in Category I applications
• 3-inch diameter fits standard B-vent system components of the same nominal size
• 48-inch rigid pipe section reduces joint count on extended vent runs
• Twist-lock connection system allows secure assembly without additional fasteners
• Round rigid profile maintains consistent flow cross-section through the vent run

Compatibility

Designed as an OEM-style replacement or new-installation component for Category I gas appliance B-vent systems requiring 3-inch diameter rigid pipe sections.

Installation Notes

Installation must be performed by a qualified technician in accordance with the appliance manufacturer instructions and applicable local codes, including the International Fuel Gas Code (IFGC). 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 the appliance listing and local code. Do not mix B-vent components of different nominal sizes without an approved transition fitting.
