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).

> Use our DUO-GAS Renovation Kits for a quick and easy connection to an existing chimney lined with a TUBINOX flexible liner.
> For a clean chimney in good condition, simply drop your new liner down your stack. For a chimney in poor condition, you can insert a larger flexible liner for the air duct and use a Poujoulat gather for connection.
> It is important that chimneys serving all types of solid fuel appliance are swept regularly to remove soot, tar and potential blockages.
