Installing the 160 mm diameter and 200 mm diameter systems 7
Static dimensions of the flue gas pipe
A Max. 50 m (max. vertical
height above the support
console)
B Max. 2 m (distance
between the pipe
brackets)
Danger!
Risk of injury due to falling parts.
The part of the flue gas pipe that protrudes
above the roof must be sufficiently rigid.
There must be no offset between the two
uppermost pipe brackets (dimension C). An
offset reduces the tensile strength of the flue
gas pipe and can lead to rotation or loosening
of the flue gas guiding.
▶
Do not install an offset between the two
upper pipe brackets.
▶
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 brackets
(dimension C) and the uppermost section
(dimension D).

Static dimensions for an offset of the flue
gas guiding

Max. 5 m
A
Max. 4 m
▶
Use 45° elbows.
▶
Only install one offset.
▶
Observe the following dimensions:
–
Length of the diagonally-guided section: ≤ 4 m
–
Distance A between 2 pipe brackets (1): ≤ 1 m
–
Length of the vertical section: ≤ 5 m
▶
Connect the 45° elbows to the extensions on both sides
using clamps (2).
7.4.3
Preparing the installation
1.
Before starting the installation, determine the route of
the flue gas guiding and the number and position of the
pipe brackets.
–
Observe the static dimensions.
–
The flue gas pipe must be positioned at a distance
of at least 20 cm from windows and other wall open-
ings.
2.
Drill a hole with a core diameter of at least:
–
160/225 system: 253 mm
–
200/300 system: 303/353 mm
