Duo-Gas - Concentric Flue System for Balanced Gas Fires - Brochure

The DUO-GAS system is a 316L stainless steel concentric flue designed for gas-fired room-sealed appliances. It brings the combustion air in and also evacuates the smoke. It can also be used as a conventional gas vent. Duo-Gas is mainly suitable for the new build market and can terminate vertically through the roof or horizontally through the wall. With our specially designed Renovation Kit, you can easily connect this concentric chimney system to an existing chimney lined with our Tubinox Gas Flex liner. It is available in 3 diameters (Ø100/150, Ø130/200 & Ø150/200).
