3. First, measure the required air pipe length* (A) and
then calculate from that the corresponding flue gas
pipe length (B) in each case:
– Length of the flue pipe: Length of the air
pipe + 40 mm
– Minimum length of air-pipe extension: 80 mm.
4. Shorten the pipes, e.g. with a saw.
5. After shortening it, lock the flue pipe (1) inside the air
pipe (2) again: Push the flue pipe back into the air pipe.
Turn the flue pipe as far as it will go.
