flue

A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors. Historically the term flue meant the chimney itself. In the United States, they are also known as vents for boilers and as breeching for water heaters and modern furnaces. They usually operate by buoyancy, also known as the stack effect, or the combustion products may be 'induced' via a blower. As combustion products contain carbon monoxide and other dangerous compounds, proper 'draft', and admission of replacement air is imperative. Building codes, and other standards, regulate their materials, design, and installation.

    Must balanced flue inner and outer be the same length?

    Hi. Our builders hit a problem with extending the balanced flue through a new extension. Their solution was to have the outer, intake pipe terminate at an external wall, but add an extra section to the inner pipe to take the exhaust away from the next house. However, the gas boiler was...

    Flue marked as Dangerous?

    Hi, I've just had my combi boiler marked as at risk / possibly dangerous due to some small "Thumbnail size" corrosion / oxidation of the end of the flue pipe, which I guess is due to years of condensation sitting at the end of the pipe. I appreciate that a damaged flue could let exhaust...
