The DuraVent 5DBK-X6 DVL Increaser, part number 5DBK-X6, is a double-wall black stovepipe adapter designed to transition from 5-inch to 6-inch diameter DuraVent DVL stovepipe systems. This increaser allows a properly engineered diameter change within a connector pipe run while maintaining the integrity of the double-wall construction. Finished in black to match DVL components, it provides a secure and compatible transition between specified pipe sizes.
This component is intended for use in DuraVent DVL double-wall stovepipe installations where appliance flue collar size differs from the required chimney connector diameter. Proper sizing and installation are critical to ensure draft performance and code compliance. Installation must follow DuraVent manufacturer instructions and be used only within approved DVL systems.
