16. For the adjustment range of 90 mm to 160 mm, remove
the external bracket.
–
The adjustment range of the external wall pipe
brackets ranges from 50 mm to 90 mm. For larger
wall clearances, extensions are required for the ex-
ternal wall pipe brackets. This allows you to reach a
wall clearance of 300 mm.
17. Screw the external wall pipe brackets directly to the
lower section of the extension for the external wall pipe
brackets.
18. Install the sections of flue pipework and, if required, the
inspection opening and the elbows and the terminal.
–
The terminal is made from stainless steel on the
flue gas side. This means that the flue gas terminal
is also resistant to UV radiation.
–
The distance from the terminal to the roof area
must be at least 40 cm, and for product outputs
above 50 kW, it must be at least 100 cm.
19. Tighten all wall fastenings and air pipe clamps.
5.13.5 Installing the rain penetration collar
Note
If the flue system is routed through a roof over-
hang, the rain penetration collar must be installed
on the flue system.
1. Position the rain penetration collar.
2. Tighten the clamping screw.
3. Seal the gap between the rain penetration collar and
the flue system using a UV-resistant material so that it
is permanently elastic.
5.13.6 Installing an extension that can be shortened
Note
In the case of an extension that can be shortened
(article number 0020042755), the spacer for cent-
ring the flue pipe in the external pipe is not con-
nected to the external pipe. The external pipe
does not have a bead on the insert side because
this side is shortened.

1. To shorten the extension, pull the flue pipe (1) out from
the external pipe (2) .
2. Shorten the flue pipe and external pipe by an equal
amount.
