5.3 Installing the roof exit for air pipe

To prevent possible recirculation of fl ue gas, the fl ue system
installer must take account of effects such as the prevailing
wind conditions, any eddy zones, the specifi cs of
the site, etc. in the design of the fl ue and air supply systems.
Buderus can not be held responsible for such
potentially detrimental effects on boiler operation. The
clearances detailed or illustrated should be seen as the
absolute minimum and may in some circumstances not be
adequate for specifi c installations.
