Installing The Roof Exit For The Air Pipe - Buderus Logano plus GB312 Installation Manual

V Remove the side panel if not already removed.
V Unscrew the cover plate from the rear panel.
To avoid problems when fitting the gas con-
nection, it is best to fit a 90° elbow for the air
pipe connection.
V Connect the air pipe 90° elbow to the air pipe socket
through the rear panel and seal.
V Construct the air supply pipe using a standard air pipe
system according to the national requirements.
We recommend the fitting of a protective grille (bird
screen) to the air pipe terminal. For details of correct
dimensioning, contact the manufacturer concerned.
6.6 Installing the wall exit for the air pipe
To prevent possible recirculation of flue gas, the flue sys-
tem installer must take account of effects such as the pre-
vailing wind conditions, any eddy zones, the specifics of
the site, etc. in the design of the flue and air supply sys-
tems. Buderus can not be held responsible for such
potentially deleterious effects on boiler operation. The
clearances detailed or illustrated in Fig. 12 and Fig. 16
should be seen as the absolute minimum and may in some
circumstances not be adequate for specific installations.
