Example of installation with direct vertical terminal in partially pro-
tected location.
When the vertical terminal for direct discharge of combus-
tion fumes is used, a minimum gap of 300 mm must be left between the
terminal and the balcony above. The distance A + B (always with respect to
the balcony above), must be equal to or less than 2000 mm.
• Configuration without cover kit in a partially protected location
(boiler type C).
N.B.:
a partially protected location is one in which the appliance is not exposed
to the direct action of the weather (rain, snow, hail, etc..).
By leaving the side plugs fitted it is possible to install the appliance exter-
nally without the cover kit. Installation is carried out using the concentric
Ø60/100 intake / exhaust kit, for internal installation of which reference
is made to the relevant paragraph. In this configuration the Top cover kit,
which guarantees additional protection for the boiler, is recommended but
not compulsory.

Internal installation (boiler type C).
The Victrix 24 kW X boiler can be installed internally both in configura-
tion C and B

.
Immergas supplies various solutions separately from the boiler for the instal-
lation of air intake and flue extraction; fundamental for boiler operation.
Important: the boiler must only be installed together with an original
Immergas “Green Range” air intake and fume extraction system in
plastic, as required by current regulations. This system is identifiable
by a special distinctive marking bearing the note: “for condensing
boilers only”.
• 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. 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 seals (black) for “Green Range“ fume extraction system.
Make sure that you place the seal (for bends or extensions) correctly, as
shown in the figure:
- seal (A) with notches, to be used for bends;
- seal (B) without notches, to be used for extensions.
N.B.:
if the lubrication of the components (already carried out by the manu-
facturer) is insufficient, remove the residual lubricant using a dry rag, then
cover the parts with the talc supplied in the kit, to facilitate coupling.
