1.7 IMMERGAS FLUE SYSTEMS.
Immergas supplies various solutions separately
from the boilers regarding the installation of air
intake terminals and flue extraction, which are
fundamental for boiler operation.
Attention: the boiler must only be installed
together with an original Immergas air intake
and flue gas exhaust system, in compliance
with the standards in force. This system can be
identified by an identification mark and special
distinctive marking bearing the note " not for
condensing boilers".
The flue exhaust pipes must not be in contact with
or be near to flammable materials. Moreover,
they must not pass through buildings or walls
made of flammable 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 figure
(Fig. 1-7).
• Resistance factors and equivalent lengths.
Each flue component has a
Resistance Factor
based on experimental 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 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
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 flue configurations.
•
Coupling of extension pipes. To install any
push-fit extensions with other flue extraction
elements, it is necessary to do the following:
install the concentric pipe or elbow with the
male side (smooth) on the female section
(with lip seal) to the end stop on the previously
installed element. This will ensure the sealing
and joining of the elements correctly.
Attention:
if the exhaust terminal and/or
extension concentric pipe needs shortening,
consider that the internal duct must always
protrude by 5 mm with respect to the external
duct.
Diaphragm installation.
Attention:
based on the boiler model (checking
which type of fan is installed), use appropriate
diaphragms.
For correct functioning of the boiler it is
necessary to install a diaphragm on the outlet
of the sealed chamber and before the intake
and exhaust pipe. The appropriate diaphragm is
chosen based on type of pipe and its maximum
extension: this calculation can be made using
the tables below:
N.B.:
the diaphragms are supplied together with
the boiler.
