Duravent 3DV24 B-vent Flex Connector Pipe 3x24 Inches

Product Description

The DURAVENT 3DV24 is a double wall air-insulated flexible B-vent connector pipe designed to link Category I gas appliances to Type B vent systems. Built with a 3-inch diameter and a 24-inch length, this flex connector bridges the appliance flue outlet to the main vent run while maintaining proper flue gas temperatures and required clearances. Its double wall air-insulated construction helps preserve draft integrity and reduces heat transfer to combustibles. Licensed HVAC technicians and gas appliance installers typically handle this component as part of a compliant venting assembly.

This connector is suited for residential and light commercial installations where a short, flexible transition is needed between a Category I gas appliance and an existing B-vent system. Typical applications include gas furnaces, boilers, and water heaters vented through a Type B double wall vent system. The 3-inch diameter suits smaller gas appliances with matching flue outlet sizing, and the 24-inch length provides adequate reach for most standard appliance-to-vent connections.

Key Features

• 3-inch diameter fits Category I gas appliance flue outlets and B-vent systems of the same size
• 24-inch flexible length accommodates minor offsets between the appliance outlet and vent stack
• Double wall air-insulated construction maintains flue gas temperature and proper draft
• Flexible design eases installation in tight spaces or where rigid pipe alignment is difficult
• Designed for Type B vent applications requiring maintained clearances to combustibles

Compatibility

Designed as an OEM-style replacement and new-installation flex connector for Type B double wall vent systems serving Category I gas appliances with a 3-inch flue outlet.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance installer in accordance with the appliance manufacturer instructions and applicable fuel gas codes such as the IFGC. Shut off the gas supply and allow the appliance to cool completely before disconnecting or replacing any vent components. Ensure all joints are properly secured and that the connector is not kinked or compressed beyond the manufacturer recommended minimum bend radius. Verify that required clearances to combustibles are maintained throughout the installed vent run.
