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
required, use the pantiles for a pitched roof. The
flue pipework must maintain a distance of 20 cm
from windows and other wall openings.

1. Drill a hole into the external wall.
– Core diameter: 150 mm
2. Preinstall the external wall console, which consists of
two brackets and a mounting plate.
– Install the external wall console at least 50 mm
above the hole in the wall so that the wall collar can
be installed on the flue pipe.
3. If there is a wall clearance of 50 mm to 150 mm, install
the support plate on the short side; if there is a wall
clearance of 150 mm to 300 mm, install the retaining
plate on the long side of the external wall console.
4. Set the required wall clearance and tighten the four
bolts (1) in a position where they can be installed.
5. Install the wall console at least 50 mm above the hole
in the wall so that the wall collar can be installed on the
flue pipe.
