6.11.2 Separate ducts (Ø 80mm)
The smoke outlet and combustion air inlet can built with sep-
arate ducts, instead of concentric ducts, using the “SEPARATE
DUCTS KIT, code. 8089932”. This is to be ordered separately
from the boiler. Connect the other accessories, chosen from
those listed in the table below, to it.

After folding the numbered sections upwards, the diaphragm (4)
must be positioned between the collar (2) and the first part of
the outlet pipe, depending on the desired pipe load loss (inlet +
outlet total length).
