Installation Diagram of the Wall-Lead Through
Safety guard
Installation instructions
1. Create a core hole in the outer wall (maximum wall
thickness 480 mm) with a diameter of at least 135
mm.
Keep an eye out for possible supply lines in this
area!
2. Insert the telescope pipe in the wall lead-through
that you created so that the outer pipe (100 mm di-
ameter) is on the inner side of the wall.
To prevent cold bridges, insulate the telescope pipe
with a suitable insulation material.
3. Place bricks around the telescope pipe in the core
hole so that it is aligned with both sides of the wall.

4. Attach the safety guard to the outer side of the wall
with 4 screws.
Mount the safety guard paying attention to the posi-
tion of the rain drainage.
5. Insert the back pressure flap inside and attach it with
4 screws as well.
The "oben" label on the back pressure flap must be
visible from inside!
6. Close the opening on the back pressure flap with the
sealing cap when taking the device out of operation,
e.g. before winter, to prevent air circulation.
