Exhaust flue pipework with flue-gas kit in
smooth propylene or smooth stainless steel
Kits are available in Ø80 mm, Ø60 mm or Ø50 mm
for expelling flue gases (a), while the air suction
kits (b) are always Ø80 mm.
When setting up any ducted system, the hollow
cavity between the secondary flue, exhaust flue
or ducted pipe and the internal wall of the tech-
nical cabinet must only be used for this system

exclusively.
All components must be made from materials
with class A1 reaction to fire according to stan-
dard UNI EN 13501-1. Note that extendible
metal hoses must not be used.
The flue must receive the flue gas output from
the flue gas duct connected to the appliance
only. Collective exhaust flues cannot be used and
the output from extractor hoods above cooking
appliances of any kind or output from other gen-
erators cannot be conveyed through the same
flue or flue gas duct.
Therefore, if you install a ducted pipe for evac-
uating combustion products from any type of
appliance inside an existing flue, this flue must
then be used solely for the ducted pipe system.
It cannot contain any other type of pipework (for
example gas, heating or solar pipes), nor can it
contain cables of any kind (electrical, TV antenna,
etc.). However, if there is enough space, it can be
used to install other ducted pipes hooked up to
appliances powered by other fuels, as long as the
minimum clearances required by the regulations
are respected.

For every additional elbow, subtract 1.5 m from
the total length.
For every tee connection, subtract 1.7 m from the
total length.
For double-walled pipes in corrugated propylene
or corrugated stainless steel, reduce the effective
A condensate siphon must also be
installed at the base of the flue-gas
kit. This is because the boiler is not
built to collect condensate from the
system for evacuating combustion
products.
