Activation of Passive Systems

  • To provide for future installation of an active SMD or SSD system, an electrical circuit terminated to a single outlet in an approved box must be installed during construction in the attic in the anticipated location of vent pipe fan.
    • In other words, the electrical box must be present and ready for a fan to be installed.
  • To provide for future installation of an active SSD, the piping length in the attic of the building shall have a minimum height of 3’ to allow for the anticipated installation of a radon mitigation fan in the vent pipe.
  • Active mitigation systems installed in new construction must be performed by a licensed mitigation professional or technician.
