BOILER INSTALLATION.
1.1 INSTALLATION
RECOMMENDATIONS.
e Victrix Tera boiler has been designed for
wall mounted installation only; for central 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 as to allow for (always in safe, ecient and comfortable
conditions):
- installation (according to the provisions of
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine, special);
- removal (to outdoors in the place for loading
and transporting the appliances and components) as well as the eventual replacement
of those 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).
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
the sealed chamber boiler for intake of air 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.
Important: Immergas declines all liability for
damages caused by boilers removed from other
systems or for any non-conformities of such
equipment.
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 Standards:
- this boiler can be installed outdoors in a
partially protected area. A partially protected
area is one in which the boiler is not exposed
to the direct action of the weather (rain, snow,
hail, etc..).
is type of installation is only possible when
permitted by the laws in force in the appliance's
country of destination.
- Installation of gas appliances, ue exhaust
pipes and combustion air intake pipes is
forbidden in places with a re risk (for example: garages, closed parking stalls), and
in potentially dangerous places.
- Installation is prohibited on the vertical
projection of the cooking surface.
- Installation is forbidden in places/rooms
that constitute public areas of apartment
buildings, internal stairways or other escape
routes (e.g. oor landings, entrance halls,
etc.).
- Installation is also forbidden in places/rooms
that constitute public areas of apartment
buildings such as cellars, entrance halls, attics,
los, etc., unless otherwise provided for by
local regulations in force.
Attention: installing the wall recessed frame
kit must guarantee the boiler stable, ecient
support. e recessed frame kit ensures appropriate support only if installed correctly
(according to the rules of good practice),
following the instructions on its instructions
leaet. e recessed frame for the boiler is not
a supporting structure and must not replace
the wall removed. It is necessary to position
the boiler inside the wall. For safety reasons
against any leaks it is necessary to plaster the
boiler housing in the brick wall.
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 boiler 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 mount.
ese boilers are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a central heating
system and domestic hot water circuit suited to
their performance and capacity.

1.3 ANTIFREEZE PROTECTION.
Minimum temperature -5°C. e boiler comes
standard with an antifreeze 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. If the boiler is
installed in a place where the temperature drops
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 (EN 1717:2002 or local standards in force).
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 (antifreeze kit) comprising two
electric heating elements, the relevant wiring
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 (Parag.
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.
N.B.: 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 INSTALLATION INSIDE A
RECESSED FRAME OPTIONAL.
e boiler is designed for installation inside the
Immergas recessed frame (supplied as optional).
e necessary parts for this type of installation
(brackets) must also be purchased separately as
optional kit.
To install proceed as follows:
- Install the bracket (2) inside the recessed frame
xing it with the screws (3) in the pre-drilled
holes (Fig. 3).
- Hang the boiler (4) to the bracket (2) (Fig. 4).
- Block the boiler (4) by mounting the brackets
(5) and xing them with their screws (6) (Fig.
5).
e brackets (5) used to centre the boiler on
the frame and hold it in place stop against the
frame (1) so do not require xing to the frame
itself.

1.5 BOILER CONNECTION UNIT.
e connection unit consisting of all the necessary parts to perform the hydraulic and gas
system connections of the appliance comes as
optional kit, perform the connections respecting
the arrangement of Fig. 6 based on the type of
installation to be made.
1.6 GAS CONNECTION.
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
nameplate). If dierent, the boiler must be converted for operation with the other type of gas
(see converting appliance for other gas types). It
is also important to check the dynamic pressure
of the mains (methane or LPG) used to supply the
boiler, which must comply with EN 437 and its
attachment, as insucient levels may reduce generator output and cause discomfort to the user.
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
standards in force.
Fuel gas quality. e appliance was designed to
operate with combustible gas free of impurities;
otherwise 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.
1.7 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 treatment of the heating and water 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.
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 1.23.
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 installation of an
automatic lling system.
In order to meet the system requirements established by EN 1717 in terms of 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. We also recommend using a category 1, 2
or 3 heat transfer uid (ex: water + glycol) in the
boiler's primary circuit (C.H. circuit), as dened
in standard EN 1717.
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
outlet. Consequently, in the event of valve intervention, the discharged liquid will end up in
the sewer system through the drain pipe of the
condensate drain trap.
In any case the lower part of the appliance is
tted with a drain tting (Ref. 3 Fig. 6) with the
relative closure cap to check for the presence of
liquid in the discharge circuit and to check the
intervention of the 3 bar safety valve.
Condensate drain. To drain the condensate produced by the appliance, it is necessary 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 occlusion and 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. 1.25). Also,
comply with national and local regulations on
discharging waste waters.
In the event condensate is not discharged into
the wastewater drainage system, a condensate
neutraliser must be installed to ensure compliance with the parameters established by the
legislation in force.

1.8 ELECTRICAL CONNECTION:
e appliance has an IPX5D protection degree;
electrical safety of the appliance is achieved 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. 7).
To carry out electrical connections, all you have
to do is open the connections compartment as
follows (Fig. 7):
- Disassemble the cover (Fig. 53).
- Disassemble the cover (b)
1) Loosen the screw (a).
2) Press the two hooks on the connections
compartment cover.
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 overvoltage category.
To protect from possible dispersions of DC voltage, it is necessary to 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. 6).
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.
3.8). In this situation it is good practice to insert
a relevant safety kit (optional) made up from a
thermostat (with adjustable temperature). e
thermostat must be positioned on the system
ow pipe at a distance of at least 2 metres from
the boiler.
1.9 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. 8).
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 day
(comfort temperature) and one for night
(reduced temperature);
- set a weekly programme with four daily
switch on and switch o times;
- selecting the required function 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.
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 44/40 and 41 eliminating
jumper X40 (Fig. 38). 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 44/40 and 41 eliminating jumper X40
on the P.C:B., paying attention not to invert the
polarity in the connections (Fig. 38). e boiler
can only be connected to one remote control.
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.
1.10 EXTERNAL TEMPERATURE PROBE
OPTIONAL.
e boiler is designed for the application of the
external temperature probe (Fig. 9), 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. 10). 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. 38).

1.11 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 system and
flue gas extraction system made of plastic,
with the exception of the C6 conguration, 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 ue can be identied by an identication
mark and special distinctive marking bearing
the note "only for condensation 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 length,
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 of the gaskets (black) for “green
range” ue extraction systems. Position the
gasket correctly (for bends and extensions)
(Fig. 11):
- 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 temporaril y.
• 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.
• Installation inside the recessed frame. In this
mode, install the ue according to your needs
using the appropriate pre-sections in the frame
to exit from its clearances.

1.13 OUTDOOR INSTALLATION IN
PARTIALLY PROTECTED AREA.
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..)..
• Conguration type B, open chamber and fan
assisted.
Using the special coverage kit one can achieve
direct air intake (Fig. 12) and ue gas exhaust
in a single chimney 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 B.
With this conguration:
- air intake takes place directly from the envi-
ronment in which the appliance is installed
(external);
- the ue gas 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. 13). Remove the
two plugs from the lateral intake holes. Now
cover the le intake hole using the relevant
plate, xing it onto the right 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 metal sheet
plate and tighten by means of the clips present
in the kit, making sure to block the 4 gasket
aps. Fit the male end (smooth) of the exhaust
terminal into 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-tting extensions with other elements
of the ue, proceed as follows: Install the pipe
or elbow with the male side (smooth) in the
female section (with lip seal) to the stop on the
previously installed element. is will ensure
sealing eciency of the coupling.
• Conguration without cover kit in a partially
protected location (type C boiler)
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 tted it is possible
to install the appliance externally without the
cover kit. Installation takes place using the
Ø60/100 and Ø 80/125 concentric intake/
exhaust kits. Refer to the paragraph on indoor
installation. In this conguration the upper
cover kit guarantees additional protection for
the boiler. It is recommended but not compulsory. e Ø 80/80 separating device cannot be
used in this conguration.

1.14 INTERNAL INSTALLATION USING
A RECESSED FRAME WITH DIRECT
AIR INTAKE
• Conguration type B, open chamber and fan
assisted.
Using a kit separator one can achieve direct air
intake (Fig. 16) and ue gas exhaust in a single
chimney or directly outside. 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
(the recessed frame is ventilated), and only
functions in permanently ventilated rooms;
- the ue gas exhaust must be connected to its
own individual ue or channelled directly into
the external atmosphere.
The technical regulations in force must be
respected.
Separator kit installation: install the discharge
ange on the central hole of the boiler, positioning the relative gasket with the circular
projections downwards in contact with the
boiler ange, and tighten using the hex screws
with at tip contained in the kit. Remove the at
ange present in the lateral hole with respect to
the central one (according to needs) and replace
it with the intake ange, positioning its gasket
already present in the boiler and tighten using
the supplied self-threading screws. Fit the male
side (smooth) to the bends in the female side of
the anges.
e intake bend must face the rear side of the
boiler.
Fit the exhaust pipe with the male side (smooth)
to the female side of the bend up to the end stop,
making sure that the internal wall sealing plate
has been tted and connecting the required ue
according to personal requirements.
