1. Determine the pipe length (→ Installation instructions
for the boiler) and define the location of the wall duct.
2. Measure the clearance Y from the external wall to the
installation surface for the boiler.
3. Set the required pipe length:
– At least: Y + 24 mm
– Maximum: Y + 28 mm
– If you install the collar outside, add 12 mm to the
total pipe length.
– If the terminal is below a roof overhang or a ho-
rizontal surface, you can pull the wall duct up to
500 mm out of the wall in order to guarantee that
the flue gases are extracted without any obstruc-
tions.

– Ensure that the flue pipe's recess snaps into place
in the air pipe's latching lug.
