## Long description

Flue Pipe Extension Vaillant 80/125 mm L=2000 mm PP is a polypropylene concentric flue extension engineered for use with Vaillant balanced flue gas boilers and water heaters. The product features an outer diameter of 125 mm and an inner duct diameter of 80 mm arranged concentrically to preserve sealed intake and exhaust airflow. At a length of 2,000 mm, this extension provides a straightforward way to route the concentric flue system through walls, ceilings, or external runs while maintaining compatibility with Vaillant concentric components and preserving flue performance.
Advantages
The polypropylene (PP) construction offers chemical and corrosion resistance and low weight for easier handling and installation. Concentric 80/125 mm geometry keeps combustion air and exhaust separated in a sealed duct, reducing the risk of ingress and ensuring correct airflow balance. The 2 m length minimizes the number of joints required for longer runs, which helps to maintain system tightness and reduces potential leakage points. The component is suitable for both internal and external routing when fitted in accordance with Vaillant installation requirements.
Suitable for

How to use
Fit the flue pipe extension as part of a compatible Vaillant concentric flue assembly, ensuring clean, square cuts and correct alignment to adjoining components.

Verify that the outer sleeve and inner duct remain concentric and that seals and clips are correctly engaged.
