1.11 Immergas ue systems.
Immergas supplies various solutions separately from the boilers
regarding the installation of air intake terminals and ue exhaust,
which are fundamental for boiler operation.
ATTENTION:
the boiler must only be installed togeth-
er with an original Immergas air intake
and ue gas exhaust system.
is ue can be identied by an identication
mark and special distinctive marking bearing
the note "not for condensing boilers".
e ue exhaust pipes must not be in contact
with or be near to ammable materials. More-
over, they must not pass through buildings or
walls made of ammable material.
See following paragraphs for the detailed description of the kits
available
• Positioning of double lip seals.
For correct positioning of lip seals on elbows and extensions,
follow the direction of assembly given in gure (Fig. 8).
• Resistance factors and equivalent lengths.
Each ue component has a Resistance Factor based on exper-
imental tests and specied in the table below. e 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 single component has a resist-
ance corresponding to a certain length in metres of pipe of the
same diameter; the so-called equivalent length, can be obtained
from the ratio between the relative Resistance Factors.
All boilers have an experimentally obtainable maximum Re-
sistance 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. is information allows calcula-
tions to be made to verify the possibility of setting up various
ue congurations.
