Duravent 0703PI B-vent Round Rigid Pipe 7x36 Inches

Product Description

The DURAVENT 0703PI is a double wall air-insulated B-vent round rigid pipe section designed for Category I gas appliance venting systems. Measuring 7 inches in diameter and 36 inches in length, this pipe section uses double wall air-insulated construction to maintain flue gas temperature throughout the vent run, which supports proper draft and meets clearance-to-combustibles requirements. It connects via a twist-lock interface for secure, field-efficient assembly. HVAC technicians and plumbers install this pipe as part of natural draft gas venting systems in residential and light commercial applications.

This pipe section is suited for vertical and offset B-vent installations serving Category I gas appliances such as furnaces, boilers, and water heaters that require natural draft venting. The double wall air-insulated design is appropriate for interior vent runs where maintaining flue gas temperature is critical to system draft performance. It is intended for use within a complete DVP B-vent system using compatible fittings, elbows, and terminations of the same diameter.

Key Features

• 7-inch diameter and 36-inch length for standard B-vent vent runs
• Double wall air-insulated construction maintains flue gas temperature and supports natural draft
• Twist-lock connection system allows secure, tool-efficient field assembly
• Designed for Category I gas appliance venting in residential and light commercial systems
• Round rigid construction provides consistent airflow cross-section throughout the vent section

Compatibility

Designed as an OEM-style component for use within DVP B-vent systems requiring 7-inch diameter round rigid pipe sections for Category I gas appliance venting.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions, NFPA 54, and local mechanical codes. Shut off the gas supply and allow the appliance to cool completely before servicing or modifying any vent section. Verify that all twist-lock connections are fully engaged and that proper clearances to combustibles are maintained throughout the vent run. Do not mix pipe diameters or vent system types within a single venting assembly.
