Boiler Flue Extensions

Boiler flue extensions are designed to extend the length of the boiler flue pipe that removes exhaust gases from a boiler (such as carbon monoxide) outside of a building. A boiler flue extension is a functional accessory enabling the flue to exit your building with ease. In this section of our website, you'll find extensions with a range of dimensions and from various brands.
