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 hol-
low cavity between the secondary flue, ex-
haust flue or ducted pipe and the internal wall
of the technical cabinet must only be used for
INSTALLATION
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 generators 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 sys-
tem. It cannot contain any other type of pipe-
work (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 propyl-
ene or corrugated stainless steel, reduce the
effective length by 15%.
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.
