46 Air/flue pipe installation manual 8000026412_01
– 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.
21. Tighten all wall fastenings and air pipe clamps.
5.17.5 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.
5.17.6 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.
– Shorten the flue pipe and external pipe at the side
facing away from the sleeve. The spacer must re-
main locked on the flue pipe.
3. Slide the flue pipe back into the external pipe.

2 Clamp
Warning.
Risk of injury due to falling parts.
The external pipe of the extension that can
be shortened does not have a bead on the
underside. The clamp cannot stabilise the
pipework system.
▶ Install an additional external wall pipe
bracket so that the system cannot be dis-
connected and become loose as a result
of the wind load.
4. Install an additional external wall pipe bracket directly
above the extension that can be shortened.
