1.6 IMMERGAS FLUE SYSTEMS.

Immergas supplies various solutions separately
PL
from the boiler regarding the installation of air
intake terminals and flue extraction, which are
fundamental for boiler operation.
CZ
Important: the boiler must be installed ex-
clusively with an original Immergas "Green
Range" air intake and fume extraction system
in plastic. This system can be identified by
HU
an identification mark and special distinctive
marking bearing the note: "only for condens-
ing boilers".

• Resistance factors and equivalent lengths.
Each flue extraction system component has
a Resistance Factor based on experimental
tests and specified in the table below. The
IE
resistance factor for individual components is
independent from the type of boiler on which
it is installed or the actual dimensions. It is,
however, conditioned by the temperature of the
SK
fluids that pass through the pipe and therefore
varies according to applications for air intake
or flue exhaust. Each single component has a
resistance corresponding to a certain length
in metres of pipe of the same diameter; the
so-called equivalent length, obtained from the
ration between the relative Resistance Factors.
All boilers have an experimentally obtainable
maximum Resistance Factor equal to 100. The
maximum Resistance Factor allowed corre-
sponds to the resistance encountered with the
maximum allowed pipe length for each type
of Terminal Kit. This information enables
calculations to verify the possibility of various
configurations of flue extraction systems.
Positioning of the gaskets (black) for "green
range" flue extraction systems. Position the
gasket correctly (for bends and extensions)
(Fig. 1-9):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for exten-
sions;
N.B.: if component lubrication (already carried
out by the manufacturer) is not sufficient, remove
the residual lubricant using a dry cloth, then to
ease fitting spread the elements with common
or industrial talc.

ASSISTED (OPTIONAL).
In this configuration the relevant terminal "1"
must be used (present in the appropriate intake
kit for the installation in question) to be placed
on the intake hole above the sealed chamber (Fig.
1-10). Air intake takes place directly from the
environment and flue exhaust in individual flue
or to the outside. The boiler in this configura-
tion, following the assembly instructions stated
on the relative instruction sheet, is classified as
type B .
23
With this configuration:
- air intake takes place directly from the environ-
ment in which the boiler is installed and only
functions in permanently ventilated rooms;
- the flue exhaust must be connected to its own
individual flue or channelled directly into the
external atmosphere.
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours
or substances (e.g. acid vapours, glues, paints,
solvents, combustibles, etc.), as well as dusts
(e.g. dust deriving from the working of wood,
coal fines, cement, etc.), which may be dama-
ging for the components of the appliance and
jeopardise functioning.
Max. length of exhaust duct. The exhaust duct
(in vertical or in horizontal) in order to prevent
problems of flue condensation owing to their
cooling through the wall can be extended to a
max. measurement of 30 straight metres.
