The Vaillant 1970mm Flue Extension is designed to extend the length of a standard Vaillant flue system, allowing greater flexibility when installing a boiler where the flue needs to travel further to reach an external wall or roof terminal. This extension is installed between flue elbows, vertical adaptors, and vertical terminals to increase the overall flue length by up to 1,970mm.
It is suitable for use with all Vaillant ecoTEC condensing boiler models and is ideal for installations where the boiler is located further away from an external wall or where additional flue length is required to meet installation regulations.
Manufactured to Vaillant’s high standards, this flue extension is designed to maintain safe and efficient removal of combustion gases while ensuring the heating system operates correctly and safely.
A flue extension is used when the standard flue supplied with a boiler is not long enough to reach the outside of the building. This often occurs in larger properties, plant rooms, or where the boiler is positioned away from an external wall. Adding a flue extension allows the system to be installed safely and in line with manufacturer guidelines and building regulations.
