The Vaillant 470mm Flue Extension is designed to extend the length of a Vaillant flue system where additional distance is required to reach an external wall or roof terminal. This extension can be installed between flue elbows, vertical adaptors, and vertical terminals to increase the total flue length by up to 470mm.
It is suitable for use with Vaillant ecoTEC HE condensing boiler models and is ideal for installations where only a small extension is required to complete the flue run. This helps ensure the flue system can be installed safely and in line with manufacturer installation guidelines.
Manufactured to Vaillant’s high standards, this flue extension provides a secure connection and helps maintain safe and efficient removal of combustion gases from the boiler.
A flue extension is used when the standard flue supplied with a boiler is not long enough to reach the outside of the building. A shorter extension like this 470mm version is ideal when only a small adjustment to the flue length is required to complete the installation safely and correctly.
