6.7 Installing the roof penetration for the air pipe
To prevent possible recirculation of flue gas, the flue system installer
must take account of effects such as the prevailing wind conditions, e. g.
any eddy zones, the specifics of the site, etc. in the design of the flue and
air supply systems. Buderus can not be held responsible for such
potentially deleterious effects on boiler operation. Multi-boiler systems must be installed according to the specifications of ANSI Z223.1.
The clearances detailed or illustrated in Fig. 14 and Fig. 17 should be
seen as the absolute minimum and may in some circumstances not be
adequate for specific installations.
