Duravent 0502PI B-vent Round Rigid Pipe 5x24 in Double Wall

Product Description

The DURAVENT 0502PI is a double-wall, air-insulated B-vent round rigid pipe section measuring 5 inches in diameter and 24 inches in length. It is designed for extending vent runs in Category I gas appliance systems, where natural draft is used to exhaust flue gases to the outside. The double-wall, air-insulated construction maintains safe outer surface temperatures while channeling combustion gases away from the appliance. This pipe section connects using a twist-lock mechanism for a secure, repeatable joint. Licensed HVAC technicians and plumbers install this type of vent pipe during new construction and service work on gas-fired furnaces, boilers, and water heaters.

This pipe section is suited for residential and light commercial applications where Category I, natural-draft gas appliances require code-compliant venting. Typical installations include extending a B-vent trunk line through a mechanical room, utility chase, or attic space to reach the vent termination point. The 24-inch rigid section is a standard length used to span consistent framing bays or to make up a specific run dimension when combined with other B-vent components in the same system.

Key Features

• 5-inch diameter and 24-inch length for standard vent run extensions
• Double-wall, air-insulated construction reduces outer surface temperature and meets Category I venting requirements
• Twist-lock connection system provides a secure, tool-assisted joint between sections
• Round rigid pipe format maintains consistent flow cross-section throughout the vent run
• Compatible with other B-vent DVP-series components for full system assembly

Compatibility

Designed as an OEM-style replacement and extension component for Category I natural-draft gas appliance B-vent systems using 5-inch diameter DVP-series pipe and fittings.

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 local mechanical codes. Shut off gas supply and allow the appliance to cool completely before servicing any vent components. Ensure all twist-lock joints are fully engaged and that the vent system maintains proper clearances to combustibles as required by the listing and local code. Do not mix B-vent pipe diameters or connect DVP components to single-wall vent pipe within the same system run.
