The VIT-Smooth Flue Damper - Ø 100mm is the perfect addition to ensure optimal performance and safety for your heating appliances. Crafted from zero carbon steel and finished with a durable powder vitreous enamel coating in matt black, this single-skin connector efficiently manages flue gases for gas, oil, and solid fuel appliances with temperatures up to 600°C. Designed to be a connecting pipe that bridges your appliance to a Flue Liner, Chimney Stack, or Twin Wall Flue System, it should not be used to penetrate ceilings or combustible walls.

Installation is straightforward, requiring no sealing thanks to its friction fit joints, although jointing compounds can be used for added security. When cutting the pipe, ensure that exposed steel is covered with high-temperature paint to prevent rust. Proper maintenance, including annual sweeping and inspection, especially for solid fuel applications, will help maintain optimal performance.

• Always use the VIT-Smooth Flue Damper as a connecting pipe between your appliance and the flue system (Flue Liner, Chimney Stack, or Twin Wall Flue System). • Never use the damper to penetrate ceilings or combustible walls to avoid fire risks. • When cutting the pipe to size, ensure any exposed steel is covered with high-temperature paint to prevent rust. • The friction fit joints provide a secure installation; however, jointing compounds like high-temperature silicone or fire cement can be used for added security. • Regular maintenance (e.g., annual cleaning and inspection, particularly for solid fuel applications) is recommended. • Always wear appropriate personal protective equipment (PPE) during installation and maintenance.

Yes, it is suitable for gas, oil, and solid fuel appliances with temperatures up to 600°C.

Ensure that no part of the VIT-Smooth Flue Damper is installed within 375mm of combustible materials like wood or plasterboard.

The pipe is designed to be cut. However, make sure to cover any exposed steel with high-temperature paint to prevent rust.
