WARNINGS
– The smoke flue and the connection to the flue pipe
must be in compliance with the national and local
Standards and Legislation in force.
– The use of rigid ducts which are resistant to
temperature, condensate, mechanical stress and
are air-tight is compulsory.
– Outlet ducts which are not isolated are a risk of
danger.

2.11.2 Separate ducts (Ø 80mm)
Constructing outlets for separate ducts indicates the use of the
"air-smoke split pipe system". This is to be ordered separately
from the boiler and when connected to the other accessories,
from those listed in the table below, completes the smoke-
outlet/ combustion air inlet assembly.
The total maximum length obtained from the length of the outlet
and inlet pipes is determined by the load loss of the individual
accessories and must not be greater than 9 mm H
