5.17.3 Observing the static dimensions
Before starting the installation, determine the route of the
flue system and the number and position of the wall consoles
and external wall pipe brackets.
Danger!
Risk of injury due to falling parts.
Exceeding the static dimensions may lead
to mechanical damage to the flue system. In
extreme cases, parts may become loose from
the wall and fall, thus endangering persons.
▶ During installation, observe the static di-
mensions.
▶ Secure at least every second extension to
the external wall using a pipe clamp.
▶ On façades with thermal insulation com-
posite systems, use fixing elements that
are permitted for this, if required, in order
to securely connect the flue pipework to
the structure.
