Duravent 0604PI B-vent Rigid Pipe 6x48 Inches Double Wall

Product Description

The DURAVENT 0604PI is a double wall air-insulated B-vent round rigid pipe section designed for venting Category I gas appliances. With a 6-inch diameter and 48-inch length, this pipe section handles long vent runs where maintaining proper draft is critical. The double wall air-insulated construction creates a buffer zone between the inner liner and outer wall, promoting consistent flue gas temperatures and reducing heat transfer to surrounding materials. Licensed gas appliance technicians and HVAC professionals install this component as part of listed B-vent systems on natural gas and propane appliances.

This pipe section fits into residential and light commercial venting systems serving Category I gas appliances such as furnaces, water heaters, and boilers that require B-vent. The 48-inch rigid section is well suited for straight vertical or horizontal vent runs where a full-length section reduces the number of joints needed. It connects to compatible B-vent fittings, elbows, and terminations within the same venting system series.

Key Features

• 6-inch diameter accommodates mid-range Category I gas appliance venting requirements
• 48-inch rigid length reduces joint count on long straight vent runs
• Double wall air-insulated construction supports proper draft and thermal performance
• Twist-lock connection system simplifies field assembly and secures sections without additional fasteners
• Round rigid profile maintains consistent flow area throughout the section

Compatibility

Designed as an OEM-style replacement and standard component for Category I gas appliance B-vent systems requiring 6-inch diameter rigid pipe sections.

Installation Notes

Installation must be performed by a licensed HVAC technician or gas appliance professional in accordance with NFPA 54 and the appliance manufacturer's venting instructions. Shut off gas supply and allow the system to cool completely before servicing or extending an existing vent system. Maintain required clearances to combustibles as specified by the listing and local codes. Inspect all twist-lock joints for full engagement before restoring appliance operation.
