Vaillant 470mm Flue Extension – 303902

This flue extension is compatible with all Vaillant EcoTec & Ecomax boilers and allows you to extend the length of the original flue by 470mm. This is an authentic Vaillant product, so you can be sure on the reliability of the flue extension kit.

The extension can be used when your standard flue is not long enough.

It is designed to blend in with the rest of your boiler system, allowing you more flexibility in your exit point from your home/business.
