For vertical installation, clamps are only required
when using offsets or in specific opening situations.
Only the terminal is equipped with a clamp as stand-
ard.
Note
The terminal is made from black plastic on
the flue gas side and is therefore also resist-
ant to UV radiation.
2. Tighten all wall fastenings.
3. In each case, attach a clamp (1) to the component that
is to be connected.
4. Place the clamp (1) over the two external seams ( (5)
