Flue 90 degrees to the floor

This technical drawing provides detailed information about the installation and weatherproofing for flues installed 90 degrees to the floor. Download it to gain a thorough understanding of best-practice installation in both commercial and residential applications. Flues are used to convey exhaust gases to the outdoors. The source of the gases could be a fireplace or wood burner, as well as a boiler, generator or industrial machinery in a factory setting. Flues should be installed to avoid as many bends as possible. This is because bends make it easier for soot or other debris to build up, potentially causing blockages. Depending on the flue type, it may be installed at 90 degrees, or perpendicular, to the floor through a roof penetration, as detailed in this technical drawing, or horizontal to the floor through a vertical penetration. To ensure a fully weatherproof seal around the flue, we recommend the installation of Jones and Woolman UK’s in-situ weathering solution. Comprising a cold-applied GRP system, along with a GRP sleeve, our system provides a long-lasting and durable seal that prevents rainwater ingress and protects against wind and frost damage.
