  • Page 25: Concentric System

    7.3 Concentric system 7.3.1 General The appliance is connected to a flue gas discharge / combustion air supply system delivered by DRU, hereafter referred to as the concentric system. DRU has different concentric systems in its range. In the case of a concentric system, the inner tube is used as flue gas discharge. The combustion air is supplied by the outer tube.
  • Page 26 Build the system up from (the flue spigot of) the appliance. Connect the concentric pipe pieces and, if necessary, the bend(s). Apply a clip binding with silicon sealing ring on each connection (does not apply to DRU LAS ES-E 200/150/100, here the sealing ring is inside the tube).
  • Page 27: Roof Terminal (C31)

    My Flue Assist is a DRU web application to check whether an intended concentric system is permissible and provides advice on how to adjust the appliance. Go to the DRU Service website for My Flue Assist. The information from the installation manual is always leading.
