Duravent 0504PI B-vent Round Rigid Pipe 5x48 in Double Wall

Product Description

The DURAVENT 0504PI is a double-wall, air-insulated B-vent round rigid pipe section designed for Category I gas appliance venting systems. Measuring 5 inches in diameter and 48 inches in length, this pipe section is built for long vent runs where consistent draft and thermal performance are required. The double-wall, air-insulated construction maintains flue gas temperature to support proper natural draft, reducing the risk of condensation and draft failure. Licensed gas technicians and HVAC professionals install this pipe as part of a complete DVP B-vent system on gas-fired furnaces, boilers, and water heaters.

This pipe section is suited for residential and light commercial Category I gas appliance venting applications. The 48-inch rigid length makes it a practical choice for long straight runs in attics, mechanical rooms, and chase installations. It connects using a twist-lock mechanism, allowing secure, tool-free joining with other DVP-series B-vent components. Proper sizing of the complete vent system should follow the appliance manufacturer specifications and applicable fuel gas code tables.

Shut off the gas supply and allow the appliance to cool completely before servicing or extending any vent system. Vent system sizing, clearances to combustibles, and support intervals must comply with the appliance manufacturer instructions and the authority having jurisdiction.
