1.9 INSTALLATION OF THE AIR
INTAKE AND FLUE EXHAUST
TERMINALS.
Immergas supplies various solutions separately
from the boilers regarding the installation of air
intake terminals and ue extraction, which are
fundamental for boiler operation.
Attention: the boiler must be installed
exclusively with an original Immergas “Green
Range” air intake and fume extraction system
in plastic, as envisioned by Standard in
force. This system can be identified by an
identification mark and special distinctive
marking bearing the note: “only for condensing
boilers”.
For type B
23
boilers:
e plastic pipes cannot be installed outdoors,
for tracts longer than 40 cm, without suitable
protection from UV rays and other atmospheric
agents.
• Resistance factors and equivalent lengths. Each
ue extraction system component is designed
with a Resistance Factor based on preliminary
tests and specified in the table below. The
Resistance Factor for individual components is
independent from the type of boiler on which
it is installed and has a dimensionless size. It is
however, conditioned by the temperature of the
uids that pass through the pipe and therefore,
varies according to applications for air intake
or ue exhaust. Each individual component has
a resistance corresponding to a certain length
in metres of pipe with the same diameter; the
so-called equivalent length. All boilers have an
experimentally obtainable maximum Resistance
Factor equal to 100. e maximum Resistance
Factor allowed corresponds to the resistance
encountered with the maximum allowed pipe
length for each type of Terminal Kit. This
information allows calculations to be made to
verify the possibility of setting up various ue
congurations.
Gasket for "green series" flue extraction
elements. In the event component lubrication
(already carried out by the manufacturer) is not
sucient, remove the residual lubricant using a
dry cloth, then to ease tting spread the elements
with common or industrial talc.
