2.5.9. Fitting of the Telescopic Pipe: Steps 1–5
When assembling and installing the telescopic pipe, deformations must be
avoided! The form of the ventilator with heat exchanger installation unit is
accurately adapted to the pipe!
It is necessary to leave the space between the wall and the pipe. The inner-side
vapour barrier must be connected to the unit, if available. The same applies to
an external rain protection path, if available. There is a threat of penetration of
condensate due to an improperly attached vapour barrier or penetration of
driving rain by improperly connected rain protection path!
The standard telescopic pipe can be built into the wall of maximum thickness of
310 mm. If your building has thicker walls, you need additional pipe elements for
piping system (please, specify the wall thickness when ordering, the required
additional elements are included in a separate packaging).
Step 1
Accurately measure the total outer wall thickness (including plaster layer). Add extra 10 mm.
Step 2
The piping is pre-assembled. You can supplement the piping inside, as appropriate, by the
necessary elements to the pipe length determined in Step 1:
Inner
Outer
