► Slide the disconnect device (6) (Fig. 5.14 Example: balanced ue [mm]) fully into the socket (5).
► Slide the next balanced ue pipe (5) 50 mm into the socket of the disconnect device (6).
► Ensure that the balanced ue pipe (5) is fully secured in this position, e. g. with a pipe clamp (7) or with

Installingabalancedueinanexistingchimney/duct
► Make sure that there is appropriate clearance between the outside of the ue and the wall of the duct
(Fig. 4.6 Minimum shaft size [mm]).
► Flue lines, retaining straps and spacers must be installed in channels and ducts in such a way that the
ventilated cross-section can be inspected and cleaned.
► Close cleaning apertures in ducts with chimney cleaning covers which have been assigned an
approved test mark.
► The outlets of ue lines in ducts must be designed so that the following requirements are met:
– no ingress of precipitation
– secondary ventilation can ow freely
► It must be possible to remove removable covers without tools and they must be secured to prevent
them falling.
