Vaillant 3815 AIR Flue Extension 1970mm 303905 105262

This flue extension is designed for use with compatible Vaillant air flue systems, extending the reach by 1970mm. It allows for greater flexibility when positioning boilers, especially in installations where the standard flue length is insufficient due to building layout or regulations.

On site, this extension is typically fitted by heating engineers during boiler installation or upgrade work. It connects easily to existing Vaillant flue components, making it suitable for projects requiring extended flue runs to safely route exhaust gases to the exterior of the property.
