Installing a balanced flue in an existing chimney/duct
► Make sure that there is appropriate clearance between the outside of the flue 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 flue lines in ducts must be designed so that the following requirements are met:
– no ingress of precipitation
– secondary ventilation can flow freely
► It must be possible to remove removable covers without tools and they must be secured to prevent
them falling.
