Duravent 4dvc 4 Inch Single-wall Appliance Connector

Product Description

The DURAVENT 4dvc is a single-wall appliance connector designed to attach a gas-fired appliance to a vent connector pipe. Measuring 4 inches in diameter, this connector serves as the transition link between the appliance flue collar and the main vent run. Single-wall connectors are commonly used in applications where the connector runs through unconditioned space and local codes permit their use. Licensed plumbers, HVAC technicians, and gas appliance installers typically source this connector for residential and light commercial service calls.

The 4dvc is suited for use with gas-fired appliances such as furnaces, water heaters, boilers, and dryers that require a 4-inch diameter flue connection. It is used to bridge the appliance exhaust outlet to the main vent system, making it a standard component in B-vent or single-wall vent system installations. This connector is sold as a single unit and is intended for use in applications where the connected appliance exhausts through a compatible 4-inch vent run.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with local codes and the appliance manufacturer instructions. Shut off the gas supply and allow the appliance to cool completely before disconnecting or replacing any vent components. Single-wall connectors must maintain required clearances to combustibles as specified by IFGC and local authority having jurisdiction. Do not use single-wall connectors in concealed spaces where local code requires double-wall or listed B-vent pipe.
