Danger!
Risk of injury due to falling parts.
As of a vertical height of 2 m, an external wall
console is required to support the vertical
supporting forces so that the flue pipework
is not damaged by excessive loads.

Install a second external wall console after
an offset.

Danger!
Risk of injury due to falling parts.
The part of the flue pipework that protrudes
above the roof must be sufficiently rigid. You
must not install any offset between the two
uppermost pipe brackets on the external wall.
An offset reduces the tensile strength of the
flue system in strong winds and can lead to
rotation or loosening of the flue system.
▶
Do not install an offset between the two
upper external wall pipe brackets.

Note
If required, observe the existing roof overhang. If

from windows and other wall openings.
