BOILER INSTALLATION
1.1 INSTALLATION
RECOMMENDATIONS.
e Victrix X TT boiler was designed for wall
mounted installation only; for heating and production of domestic hot water for domestic use
and similar purposes.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and components) as well as their eventual replacement
with appliances and/or equivalent components.
e wall surface must be smooth, without any
protrusions or recesses enabling access to the
rear part. ey are not designed to be installed
on plinths or oors (Fig. 1-1).
By varying the type of installation the classication of the boiler also varies, precisely:
- Type B23 or B53 boiler if installed using the
relevant terminal for air intake directly from
the room in which the boiler has been installed.
- Type C boiler if installed using concentric
pipes or other types of pipes envisioned for
sealed chamber boilers for air intake and expulsion of ue gas.
Only professionally enabled companies are
authorised to install Immergas gas appliances.
Installation must be carried out according to
regulation standards, current legislation and in
compliance with local technical regulations and
the required technical procedures.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately. Packing materials (staples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children. If the appliance is installed inside or between cabinets, ensure sucient space
for normal servicing; therefore it is advisable to
leave clearance of at least 3 cm between the boiler
casing and the vertical sides of the cabinet. Leave
adequate space above the boiler for possible water
and ue removal connections. Keep all ammable objects away from the appliance (paper, rags,
plastic, polystyrene, etc.).
Do not place household appliances underneath
the boiler as they could be damaged if the safety
valve intervenes, if the drain trap is blocked, or
if there are leaks from the hydraulic connections; otherwise, the manufacturer cannot be
held responsible for any damage caused to the
household appliances.
For the aforementioned reasons, we recommend
not placing furnishings, furniture, etc. under
the boiler.
In the event of malfunctions, faults or incorrect
operation, turn the appliance o immediately
and contact an authorised company (e.g. the
Immergas Technical Assistance centre, which
has specically trained sta and original spare
parts). Do not attempt to modify or repair the
appliance alone.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
• Installation regulations:
- this boiler can be installed outdoors in a
partially protected area. A partially protected area is one in which the appliance is not
exposed to the direct action of the weather
(rain, snow, hail, etc..).
- Installation in places with a re risk is prohibited (for example: garages, closed parking
stalls), gas appliances and relative ue ducts,
ue exhaust pipes and combustion air intake
pipes.
- Installation is prohibited on the vertical
projection of cooking hobs.
- Installation is also prohibited in places/environments that constitute common parts of
oce condominiums such as stairs, cellars,
entrance halls, attics, los, escape routes,
etc. if they are not located inside technical
compartments under the responsibility of
each individual building and only accessible
to the user (for the features of the technical
compartments, see the technical standards in
force).
Attention: wall mounting of the boiler must
guarantee stable and ecient support for the
generator
e plugs (standard supply) are only to be used
to x the appliance to the wall; they only ensure
adequate support if inserted correctly (according
to technical standards) in walls made of solid or
semi-hollow brick or block. In the case of walls
made from hollow brick or block, partitions with
limited static properties, or in any case walls
other than those indicated, a static test must be
carried out to ensure adequate support.
ese boilers are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a central heating
system and hot water circuit suited to their
performance and capacity.

1.3 ANTIFREEZE PROTECTION.
Minimum temperature -5°C. e boiler comes
standard with an anti-freeze function that activates the pump and burner when the system
water temperature in the boiler falls below 4°C.
In these conditions the boiler is protected against
freezing to an ambient temperature of -5°C.
Minimum temperature -15°C. In the event the
boiler is installed in a place where the temperature falls below -5°C, the appliance can freeze.
To prevent the risk of freezing follow the instructions below:
- protect the central heating circuit from freezing
by inserting a good-quality antifreeze liquid
into this circuit, which is specially suited for
central heating systems and which is manufacturer guaranteed not to cause damage to
the heat exchanger or other components of
the boiler. e antifreeze liquid must not be
harmful to one's health. e instructions of the
manufacturer of this liquid must be followed
scrupulously regarding the percentage necessary with respect to the minimum temperature
at which the system must be kept. An aqueous
solution must be made with potential pollution
class of water 2.
e materials used for the central heating circuit
of Immergas boilers withstand ethylene and
propylene glycol based antifreeze liquids (if the
mixtures are prepared perfectly).
For life and possible disposal, follow the sup-
plier's instructions.
- Protect the domestic hot water circuit against
freezing by using an accessory that is supplied
on request (anti-freeze kit) comprising two
electric heating elements, the relevant cables
and a control thermostat (carefully read the
installation instructions contained in the accessory kit pack).
In these conditions the boiler is protected against
freezing to temperature of -15°C.
Boiler antifreeze protection (both -5°C and -15°C)
is thus ensured only if:
- the boiler is correctly connected to gas and electricity power supply circuits;
- the boiler is powered constantly;
- the boiler is not in “o ” mode;
- the boiler is not in anomaly conditions (par. 2.5);
- the essential components of the boiler and/or
antifreeze kit are not faulty.
e warranty does not cover damage due to interruption of the electrical power supply and failure
to comply with that stated on the previous page.
NOTE: if the boiler is installed in places where
the temperature falls below 0°C the domestic
hot water and central heating attachment pipes
must be insulated.

1.4 BOILER CONNECTION UNIT.
e connection unit, which is composed of all the
required accessories to connect the appliance's
hydraulic and gas system, is furnished as an
optional kit. Execute connections as indicated
in the relative instructions sheet by using the
connections represented in g. 1-3.
1.5 GAS CONNECTION APPLIANCE
CATEGORY II
2H3/P
.
Our boilers are designed to operate with methane
gas (G20) and LPG. Supply pipes must be the
same as or larger than the 3/4”G boiler tting.
Before connecting the gas line, carefully clean
inside all the fuel feed system pipes to remove
any residue that could impair boiler eciency.
Also make sure the gas corresponds to that for
which the boiler is prepared (see boiler data name
plate). If dierent, the appliance must be converted for operation with the other type of gas (see
converting appliance for other gas types). e
dynamic gas supply (methane or LPG) pressure
must also be checked according to the type used
in the boiler, which must comply with the technical standards in force, as insucient levels can
reduce generator output and cause malfunctions.
Ensure correct gas cock connection. e gas supply pipe must be suitably dimensioned according
to current regulations in order to guarantee correct gas ow rate to the burner even in conditions
of maximum generator output and to guarantee
appliance eciency (technical specications).
e coupling system must conform to technical
standards in force.
Fuel gas quality. e appliance was designed to
operate with combustible gas free of impurities;
other wise it is advisable to fit special filters
upstream of the appliance to restore the purity
of the fuel.
Storage tanks (in case of supply from LPG
depot).
- New LPG storage tanks may contain residual
inert gases (nitrogen) that degrade the mixture
delivered to the appliance casing functioning
anomalies.
- Due to the composition of the LPG mixture,
layering of the mixture components may occur
during the period of storage in the tanks. is
can cause a variation in the heating power of
the mixture delivered to the appliance, with
subsequent change in its performance.
1.6 HYDRAULIC CONNECTION.
Attention: in order not to void the condensa-
tion module warranty, before making the boiler
connections, carefully wash the heating system
(pipes, radiators, etc.) with special pickling or
descaling products to remove any deposits that
could compromise correct boiler operation.
A chemical treatment of the thermal system
water is required, in compliance with the technical standards in force, in order to protect the
system and the appliance from deposits (e.g.,
lime scale), slurry or other hazardous deposits.
In order not to void the heat exchanger warranty,
you are required to comply with what has been
prescribed in paragraph 1.21.
Water connections must be made in a rational
way using the couplings on the boiler template.
Attention: Immergas declines all liability in the
event of damage caused by the inclusion of automatic lling that is not its own brand.
In order to meet the system requirements established by the regulations in force in relation to
the pollution of drinking water, we recommend
installing the IMMERGAS anti-backow kit to be
used upstream of the cold water inlet connection
of the boiler. It is also recommended that the heat
transfer uid (e.g. water + glycol) entered in the
primary circuit of the boiler (heating circuit),
complies with the local regulations in force.
Attention: to preserve the duration and the eciency features of the appliance, in the presence
of water whose features can lead to the deposit of
scale, installation of the “polyphosphate dispenser”
kit is recommended.
3-bar safety valve. Discharge of the safety valve
has been conveyed to the condensate drain trap.
Consequently, in the event of valve intervention,
the discharged liquid will end up in the sewer
system through the drainpipe of the condensate
drain trap.
e appliance has anyhow been provided with
a drain tting (ref. 3 g. 1-3) with a relative cap
to check the presence of liquid in the drainage
circuit and to check the 3-bar safety valve.
Condensate drain. To drain the condensate
produced by the appliance, it is necessar y to
connect to the drainage system by means of
acid condensate resistant pipes, with an internal
Ø of at least 13 mm. e system connecting the
appliance to the drainage system must be carried
out in such a way as to prevent freezing of the
liquid contained in it. Before appliance ignition,
ensure that the condensate can be correctly removed. Aer rst ignition, check that the drain
trap is lled with condensate (para. 1.22). Also,
comply with national and local regulations on
discharging waste waters.

1.7 ELECTRIC CONNECTION.
e appliance has an IPX5D protection degree,
electrical safety of the appliance is reached only
when it is connected properly to an ecient
earthing system as specied by current safety
standards.
Attention: Immergas S.p.A. declines any responsibility for damage or physical injury caused by
failure to connect the boiler to an ecient earth
system or failure to comply with the reference
standards.
• Open the control panel connections compartment (Fig. 1-4).
To carry out electrical connections, all you have
to do is open the connections compartment as
follows.
- Remove the front panel (Fig. 3-15b).
- Remove the cover (b g. 1-4).
1) Loosen the two screws (a).
2) Press the two hooks on the cover (b).
3) Remove the cover (b) from the control
panel (c).
- At this point, it is possible to access the terminal
board (d).
Also ensure that the electrical installation corresponds to maximum absorbed power specications as shown on the boiler data nameplate.
Boilers are supplied complete with an “X” type
power cable without plug. e power supply
cable must be connected to a 230V ±10% /
50Hz mains supply respecting L-N polarity and
earth connection;
, this network must also
have a multi-pole circuit breaker with class III
over-voltage category.
To protect from possible dispersions of DC
voltage one must provide a type A dierential
safety device.
When replacing the power supply cable, contact a
qualied company (e.g. the Immergas Authorised
Aer-Sales Technical Assistance Service). e
power cable must be laid as shown (Fig. 1-3).
In the event of mains fuse replacement on the
P.C.B., use a 3.15A quick-blow fuse. For the
main power supply to the appliance, never use
adapters, multiple sockets or extension leads.
Installation with system operating at direct
low temperature. e boiler can directly supply
a low-temperature system by setting the ow
temperature adjustment range “t0” and “t1”
(Par. 3.11). In this situation it is good practice
to insert a relevant safety kit (optional) made up
from a thermostat (with adjustable temperature).
Execute connection to terminal boards 14 and 15,
eliminating jumper X70 (Fig. 3-2). e thermostat must be positioned on the system ow pipe
at a distance of at least 2 metres from the boiler.
1.8 REMOTE CONTROLS AND
ROOM CHRONOTHERMOSTATS
OPTIONAL.
e boiler is prepared for the application of room
chrono-thermostats or remote controls, which
are available as optional kits (Fig. 1-5).
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the accessory kit.
• On/O Immergas digital chrono-thermostat.
e chrono-thermostat allows:
- set two room temperature value: one for
daytime (comfort temperature) and one for
night-time (reduced temperature);
- set a weekly program with four daily switch
on and switch o times;
- select the required operating mode from the
various possible alternatives:
• manual operation (with adjustable tempera-
ture).
• automatic operation (with set programme).
• forced automatic operation (momentarily
changing the temperature of the automatic
programme).
e chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control De-
vice V2 (CARV2) with climate chrono-thermostat
function. In addition to the functions described
in the previous point, the CARV2 panel enables
the user to control all the important information regarding operation of the appliance and
the heating system with the opportunity to
easily intervene on the previously set parameters, without having to go to where the appliance is installed. e panel is provided with
self-diagnosis to display any boiler functioning
anomalies. The climate chrono-thermostat
incorporated into the remote panel enables
the system ow temperature to be adjusted to
the actual needs of the room being heated, in
order to obtain the desired room temperature
with extreme precision and therefore with
evident saving in running costs. e CARV2 is
fed directly by the boiler by means of the same 2
wires used for the transmission of data between
the boiler and device.
Important: if the system is subdivided into zones
using the relevant kit, the CARV2 must be used
with its climate thermostat function disabled, i.e.
it must be set to On/O mode.
Comando Amico Remoto Remote Control V2
or On/O chrono-thermostat electrical connections (Optional). e operations described
below must be performed aer having removed
the voltage from the appliance. Any thermostat
or On/O environment chrono-thermostat must
be connected to clamps 40 and 41 eliminating
jumper X40 (Fig. 3-2). Make sure that the On/
O thermostat contact is of the “clean” type, i.e.
independent of the mains voltage, otherwise the
P.C.B. would be damaged. Any Comando Amico
Remoto Remote Control V2 must be connected to
clamps 44 and 41 eliminating jumper X40 on the
P.C:B., paying attention not to invert the polarity
in the connections (Fig. 3-2).
Important: if the Comando Amico Remoto Remote Control V2 or any other On/Off
chrono-thermostat is used, arrange two separate
lines in compliance with current regulations
regarding electrical systems. No boiler pipes
must ever be used to earth the electric system or
telephone lines. Ensure elimination of this risk
before making the boiler electrical connections.

EXTERNAL PROBE
Correction law of the ow temperature depending on the external temperature
and user adjustments of the central heating temperature.
1.9 EXTERNAL TEMPERATURE PROBE
OPTIONAL.
e boiler is designed for the application of the
external temperature probe (Fig. 1-6), which is
available as an optional kit. Refer to the relative
instruction sheet for positioning of the external
probe.
e probe can be connected directly to the boiler
electrical system and allows the max. system ow
temperature to be automatically decreased when
the external temperature increases, in order to
adjust the heat supplied to the system according
to the change in external temperature. e external probe always operates when connected,
regardless of the presence or type of room
chrono-thermostat used and can work in combination with Immergas chrono-thermostats. e
correlation between system ow temperature
and external temperature is determined by the
position of the central heating selector switch on
the boiler control panel (or on the CARV2 control
panel if connected to the boiler) according to
the curves shown in the diagram (Fig. 1-7). e
electric connection of the external probe must be
made on clamps 38 and 39 on the terminal board
in the boiler control panel (Fig. 3-2).

1.10 IMMERGAS FLUE 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 be installed exclusively with an original Immergas “Green
Range” inspectionable air intake device and
fumes extraction system made of plastic, as
required by the regulations in force.
e plastic pipes cannot be installed outdoors,
for tracts longer than 40 cm, without suitable
protection from UV rays and other atmospheric agents.
is system can be identied by an identication mark and special distinctive marking
bearing the note: “only for condensing boilers”.
• Resistance factors and equivalent lengths. Each
ue component has a Resistance Factor based
on experimental tests and specied 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 resistance corresponding to
a certain length in metres of pipe of the same
diameter; the so-called equivalent leng th,
can be obtained from the ratio between the
relative Resistance Factors. All boilers have an
experimentally obtainable maximum Resistance
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. This
information allows calculations to be made to
verify the possibility of setting up various ue
congurations.
• Positioning the gaskets (black) for “green
range” ue systems. Position the gasket cor-
rectly (for bends and extensions) (Fig. 1-8):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for exten-
sions;
N.B.: if necessary, to ease the push-fitting,
spread the elements with commonly-used talc.
• Coupling extension pipes and concentric
elbows. To install push-tting extensions with
other elements of the ue, proceed as follows:
Install the concentric pipe or elbow with the
male side (smooth) on the female side (with lip
seal) to the end stop on the previously installed
element in order to ensure sealing eciency of
the coupling.
Attention: if the exhaust terminal and/or
concentric extension pipe needs shortening,
consider that the internal duct must always
protrude by 5 mm with respect to the external
duct.
• N.B.: for safety purposes, do not obstruct the
boiler intake/exhaust terminal, even temporarily.
• N.B.: when installing horizontal pipes, a min-
imum inclination of 3% must be maintained
and a section clip with pin must be installed
every 3 metres.

1.12 OUTDOOR INSTALLATION IN A
PARTIALLY PROTECTED AREA.
N.B.: a partially protected area is one in which the
appliance is not exposed to the direct action of the
weather (rain, snow, hail, etc..)..
• Conguration type B, open chamber and
forced draught.
Using the special coverage kit one can achieve
direct air intake (Fig. 1-9) and fumes exhaust in
a single ue or directly outside. In this conguration it is possible to install the boiler in a partially
protected place. In this conguration the boiler
is classied as type B23.
With this conguration:
- air intake takes place directly from the envi-
ronment in which the appliance is installed
(outside);
- the fumes exhaust must be connected to its own
single ue (B23) or ducted directly outside via
a vertical terminal for direct exhaust (B53) or
via an Immergas ducting system (B53).
The technical regulations in force must be
respected.
• Coverage kit assembly (Fig. 1-11). Remove
the two plugs and the gaskets present from
the two lateral holes with respect to the central
one. Now cover the right intake hole using the
relevant plate, xing it onto the le side using
the 2 previously-removed screws. Install the
Ø 80 outlet ange on the central hole of the
boiler, taking care to insert the gasket supplied
with the kit and tighten by means of the screws
provided. Install the upper cover, xing it using
the 4 screws present in the kit, positioning the
relevant gaskets. Engage the 90° Ø 80 bend
with the male end (smooth) in the female end
(with lip seal) of the Ø 80 ange unit until it
stops. Introduce the gasket, making it run along
the bend. Fix it using the sheet steel plate and
tighten by means of the straps present in the
kit, making sure to block the 4 gasket aps. Fit
the male end (smooth) of the exhaust terminal
into the the female end of the bend 90° Ø 80,
making sure that the relevant wall sealing
plate is already tted; this will ensure hold and
joining of the elements making up the kit.
Max. length of exhaust duct. e ue pipe (both
vertical or horizontal) can be extended to a max.
length of 30 linear metres.
• Coupling of extension pipes. To install push-t-
ting extensions with other elements of the ue,
proceed as follows: Couple the pipe or elbow
with the male side (smooth) in the female side
(with lip seal) to the end stop on the previously
installed element. This will ensure sealing
eciency of the coupling.
Example of installation with direct vertical
terminal in partially protected location. When
the vertical terminal for direct discharge of combustion fumes is used, a minimum gap of 300
mm must be le between a terminal or a balcony
above. With installations under a balcony, the
X+Y+Z+W height evaluated with regard to the
balcony above must be equal to, or more than,
2000 mm (Fig. 1-10). e term W must only be
considered if the balcony above has closed balustrade (W=0 if the balustrade is open).
• Conguration without cover kit in a partially
protected location (type C boiler)
By leaving the side plugs tted it is possible
to install the appliance externally without the
cover kit. Installation takes place using the
Ø60/100, Ø 80/125 and separator Ø 80/80
concentric intake/ exhaust kits. Refer to the
paragraph relative to indoor installation. In
this conguration the upper cover kit guarantees additional protection for the boiler. It is
recommended but not compulsory.
e cover kit includes:
N° 1 ermoformed cover
N°1 Gasket clamping plate
N°1 Gasket
N°1 Gasket tightening strap
N°1 Intake hole covering plate
e terminal kit includes:
N° 1 Gasket
N° 1 Discharge ange Ø 80
N° 1 Bend 90° Ø 80
N° 1 Drain pipe Ø 80
N° 1 Wall sealing plate
Vertical terminal kit for direct
discharge
