1.7 INSTALLATION INDOORS.
• Type C configuration, sealed chamber and
forced draught.
Immergas supplies various solutions separately
from the boiler regarding the installation of air
intake terminals and flue extraction; fundamen-
tal for boiler operation.
Important: the boiler must only be installed
together with an origin Immergas air intake
and fume extraction system. This system can
be identified by a special distinctive marking
bearing the note: “not for condensing boilers”.
The fume exhaust pipes must not be in contact
with or near flammable materials and must not
cross building structures or walls made of flam-
mable materials.
• Resistance factors and equivalent lengths.
Each flue 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 does not depend either on the type
of boiler on which it is installed or the actual
dimensions. It is based on the temperature of
fluids conveyed through the ducts 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 he 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 enables
calculations to verify the possibility of various
configurations of flue extraction systems.
Positioning of double lip seals.
For correct
positioning of lip seals on elbows and extensions,
follow the assembly direction given in the figure
(Fig. 1-7).
Fumes separator adjustment.
For correct
functioning of the boiler the fumes separator
positioned on the air/fumes extraction well must
be adjusted (Fig. 1-12).
Adjustment is carried out by loosening the
front retainer screw and moving the indicator
to the correct position, aligning its value to the
horizontal reference (Fig. 1-12). Once adjustment
has been performed, tighten the screw to fix the
separator. Appropriate adjustment takes place on
the basis of the type of pipe and its extension: this
calculation can be carried out using the fumes
separator adjustment tables.
