from the wall and fall, thus endangering
persons.
> Observe the permitted height above the
flue gas pipe.
> Secure at least every second extension
to the external wall using a pipe bracket
a
Danger!
Risk of injury due to falling parts!
An offset reduces the tensile strength of
the flue gas guiding and can lead to rota-
tion or loosening of the flue gas guiding.
> Ensure that the part of the flue gas pipe
that protrudes above the roof is suffi-
ciently rigid.
> Do not install an offset between the two
uppermost pipe brackets (dimension C).
> Install air clamps at all connecting joints
between the two uppermost pipe brack-
ets (dimension C) and the uppermost

is required, always observe the following
precautions.
> Use 45° elbows.
> Only install one offset (
¬ Fig. 8.3).
> Observe the following dimensions:
- The length of the diagonally guided
section
must not exceed 4 m.
- The distance A between 2 pipe
brackets (1) must not exceed 1 m.
- The length of the vertical section
must not exceed 5 m.
> Connect the 45° elbows to the extension
on both sides using clamps (2).
