▪ The cross-section of this installation shaft must be sized so that
between the external wall of the flue gas line
and the
internal
face of the installation shaft
the following
minimum distance
must be maintained:
▪ with a rectangular shaft cross-section:
2 cm
▪ with a round shaft cross-section:
3 cm

:
▪ Flue gas pipe without flow safeguard - vacuum operation
▪ Properties and application options of the flue gas pipe:
▪ Minimum requirements according to
Chap. 4.5.1
fulfilled.
▪ Opening for flue gas outlet to the outside
▪ Supply air directly from installation room (see
Chap. 4.2.3
).
▪ If the dimensions of the flue gas line differ from those described in
this manual, a suitable arithmetical dimensioning verification is re-
quired.
▪ For data on dimensioning, see
Chap. 14.1
.

:
▪ as for B

:
▪ Connection of more than one device to a common flue gas system
(vacuum flue gas shaft).
▪ Vertical opening for flue gas outlet.
▪ Supply air directly from installation room (see
Chap. 4.2.3
).
▪ Suitable arithmetical dimensioning verification required because
vacuum prevails in the case of the flue gas inlet into the common
air/flue gas system.
▪ For data on dimensioning, see
Chap. 14.1
.
▪ Parts under overpressure of the connection pipe must be conduc-
ted as a concentric pipe system.
B

:
▪ as for B

, but connection to associated flue gas pipe including flue
gas opening.
B
53P
:
▪ as for B

, but overpressure operation.
Spacings of brackets and offsets
The distance of the supports of the flue gas line must not be more
than 2 m in the vertical area.
In the horizontal area of the connecting lines, the brackets must be
installed so tightly that there is no risk of any gradient in the hori-
zontal area in which condensate could accumulate.
If an offset is required in the vertical part of the flue gas line, the
maximum angle must not exceed 45°. In the case of external install-
ation, the height above the last bracket must not exceed 1.5 m.
