Duravent 0603PI B-vent Rigid Pipe 6x36 Inches Double Wall

Product Description

The DURAVENT 0603PI is a double wall air-insulated B-vent round rigid pipe section designed for Category I gas appliance venting systems. Measuring 6 inches in diameter and 36 inches in length, this pipe maintains flue gas temperature through its air-insulated annular space between the inner and outer walls, helping meet clearance-to-combustibles requirements. The twist-lock connection system allows for secure, repeatable field assembly. Licensed gas fitters, HVAC technicians, and plumbers install this type of pipe when constructing or extending vertical B-vent systems on natural gas or propane appliances.

This pipe section is suited for residential and light commercial gas venting applications where Category I, fan-assisted or natural-draft appliances require a listed B-vent assembly. Common installations include furnace flue systems, water heater vents, and boiler stacks that route vertically through conditioned or unconditioned spaces. The 36-inch rigid section works within modular DVP B-vent systems, allowing contractors to achieve required vertical rise heights while maintaining proper draft characteristics.

Key Features

• Double wall air-insulated construction maintains flue gas temperature for reliable draft
• 6-inch diameter x 36-inch length for standard B-vent installations
• Twist-lock connection system for fast, secure field assembly
• Listed for Category I gas appliance venting applications
• Round rigid pipe design compatible with modular B-vent system components

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or gas fitter in accordance with NFPA 54 and the appliance manufacturer instructions. Shut off the gas supply and allow the appliance to cool completely before servicing or extending any vent system. Verify all twist-lock joints are fully engaged and support spacing, clearances to combustibles, and termination height meet local code requirements. Do not mix B-vent components from different listed systems without confirming listing compatibility.
