Maximum height for the flue gas line in m
Any restriction on the output range may require a recalculation of the
maximum permitted height for the flue gas duct. The characteristics
for the flue gas calculation can be obtained from
Fig. 4-6
and the
Chap. 14
.

Connecting a flue gas line
INFORMATION
The specialised company carrying out the work must come
to an agreement with the district chimney sweep before be-
ginning the work. Even in regions where it is not legally
specified, we recommend documenting the participation of
the district chimney sweep on a form.
Requirements
▪ The flue gas system fulfils the requirements described in
Chap.
4.5.1
.
▪ The flue gas system fulfils any required other national or regional
safety requirements.
▪ The A2 F is installed correctly.
Connection
INFORMATION
We recommend use of the associated LAS construction
sets (see
Chap. 4.5.3
). They satisfy all requirements and
are also fitted with special acid-proof seals.
The associated assembly instructions must be observed
for installing the flue gas and supply air holding system
components or their means of attachment.
1
Connect the A2 F to the flue gas system inside the installation
room (
Fig. 4-1
).
2
Place the nameplate of the flue gas duct in the installation room.

INFORMATION
In some cases, the resonance in the flue gas system can
amplify the noise at the mouth of the flue gas duct. The
noise level can be effectively reduced by using a silencer
(
E8 MSD
or
E11 MSD
).
