Abstract
An exhaust system for removing radon gas from a building. An electrical fan is mounted exteriorly of the building and is connected to and between a pair of conduits, one of which extends into the building for collection of radon gas, whereas the second tube extends outwardly to allow gas to be exhausted by the fan. A transition box located between the fan and conduit allows for the positioning of the fan apart from the building, whereas the connected conduit is positioned adjacent to blend with the building contour. A housing encloses the fan and conduits.
