Figure 7.Flue pipe installation
It is recommended that knee-shaped flue pipes are three-fold to minimise the resistance of smoke passage. It is
also recommended that one of the
used knees and positioned in a suitable place has an opening for easier and
more efficient cleaning of flue pipes. See image 7a.
