Most commonly used in vertical flue installations, the 1970mm flue extension, from Vaillant, allows you to increase the length of a standard flue pipe, permitting you to have more control over where plume is released from the property, avoiding neighbouring properties and other unsuitable areas. 

The flue extension is both quick to install, due to the simple to use push-fit connectors, and aesthetically pleasing, allowing it to blend in with the rest of the boiler system.
