of the wall duct
120 - 500
Y + 24 - 28
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: Y + 24 mm to 28 mm.
–
If you install the wall collar, add 12 mm to the total
pipe length.
–
If the opening is below a roof projection 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 obstructions.
Note
Do not shorten the telescopic flue pipe.
If the required pipe length cannot be
achieved, use extensions or the horizontal
wall/roof duct.
