INSTALLATION
1.1 INSTALLATION
RECOMMENDATIONS.
Only professionally qualied heating/plumbing
technicians are authorised to install Immergas
gas appliances.
Individual and cascade installation Victrix Pro
2ErP boilers can be installed outdoors or in a
suitable plant room.
e installation must comply with all laws and
standards in force.
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.
Attention: these boilers must be used to heat
rooms and the like; they are for heating water
to a temperature lower that boiling point at
atmospheric pressure. erefore, they must be
connected to a heating system that is suitable for
their performance and their power.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately.
Packaging materials (staples, nails, plastic bags,
polystyrene foam, etc.) constitute a potential
hazard and must be kept out of the reach of
children.
Keep all flammable objects away from the
appliance (paper, rags, plastic, polystyrene, etc.).
In the event of malfunctions, faults or incorrect
operation, turn the appliance o and contact a
qualied company (e.g. the Immergas Technical
Aer-Sales 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: these boilers are not
in any way designed for installation on bases
or oors (Fig. 1-1), but exclusively for wall
installation. e wall surface must be smooth,
without any protrusions or recesses enabling
access to the rear part. Wall mounting of the
boiler must guarantee stable and efficient
support for the boiler. The plugs (standard
supply) are to be used only in conjunction
with the mounting brackets or xing template
to fix 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. e boilers must be installed
in a way to prevent collisions and tampering.
N.B.: the hex head screws supplied in the
blister pack are to be used exclusively to x the
mounting bracket to the wall.
1.2 POSITION OF THE APPLIANCES.
e boilers can be installed:
- outdoors;
- in outdoor environments, also adjoining the
building served, located in uncovered space, as
long as structurally separated and without walls
in common, or situated on the at covering of
the building served, always without walls in
common;
- in building also destined for other use or in
places inserted in the volume of the building
served.
ese rooms must be intended exclusively to
house CH systems and must have characteristics
that comply with legislation in force.
Attention: the installation of appliances powered
with gas with a greater density than 0.8 (L.P.G.)
is only allowed in places out of the ground,
also communicating with places that are on the
ground. In both cases the walkway must not have
hollows or depressions such to create gas pockets
that determine dangerous conditions.
Height of the installation room.
Installation of individual appliance: the room
must have a minimum ceiling height of 2 m.
Installation of multiple appliances in cascade (2
÷ 5 Victrix Pro 2ErP): considering the size of the
boiler, the ue manifold (which must be installed
on a 3% gradient) and the hydraulic manifolds,
the room must have a minimum ceiling height
of 2.3 m.
e aforementioned heights allow for correct
installation of the appliances and observe the
technical regulations in force.
Position of the appliances in the room.
Individual appliance: the distances between
any external point of the boiler and the vertical
and horizontal walls of the room must allow
accessibility to the regulation, safety and control
elements for routine maintenance.
Multiple appliances, not interconnected, but
installed in the same room: the minimum distance
to maintain between several boilers installed
on the same wall must be 200 mm, in order to
allow accessibility to the regulation, safety and
control elements and routine maintenance of all
appliances installed.
Cascade installation (2 ÷ 5 Victrix Pro 2ErP):
e instructions for correct cascade installation
are provided in the respective documents or

1.4 OUTDOOR INSTALLATION.
The boiler has an IPX5D electric insulation
rating and can also be installed outdoors, without
additional protections.
Attention: all optional kits that can be potentially
connected to the boiler must be protected on the
basis of their electrical protection rating.
1.5 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 5°C.
e anti-freeze function is only guaranteed if:
- the boiler is correctly connected to gas and
electricity power supply circuits;
- the boiler is powered constantly;
- Main switch is inserted;
- the boiler is not in no ignition block (Par.
- the boiler essential components are not faulty.
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 falls
below -5°C and in the event there is no gas (or
the boiler goes into failed ignition block), 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 a potential water pollution class
of 2 (EN 1717).
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 supplier’s
instructions.
2
- Protect the condensate drain trap and relative
drain against freezing by using an accessory
supplied on request (anti-freeze kit) comprising
two electric resistances, the relevant cables
and a control thermostat (carefully read the
installation instructions contained in the
accessory kit pack).
Boiler anti-freeze protection is thus ensured only if:
- the boiler is correctly connected to electricity
power supply circuits;
- Main switch is inserted;
- the anti-freeze kit components are ecient.
In these conditions the boiler is protected against
freezing to temperature of -15°C.
The warranty does not cover damage due to
interruption of the electrical power supply and
failure to comply with that stated on the previous
page.

SC - Condensate drain (minimum
internal diameter 13 mm Ø)
1.7 GAS CONNECTION.
Our boilers are designed to operate with with
natural gas (G20) and L.P.G. Supply pipes must be
the same as or larger than the 3/4” G boiler tting
Victrix Pro 80 2ErP, 1“ Victrix Pro 100-120 2ErP.
N.B.: the gas supply pipe must be suitably dimensioned according to current regulations in
order to guarantee correct gas ow to the burner
even in conditions of maximum generator output
and to guarantee appliance eciency (technical
specications). e connection to the gas supply
must conform to standards.
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-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 L.P.G.) pressure must
also be checked according to the type used in
the boiler, which must comply with EN 437 and
relative attachments and with the local technical
regulations in force, as insucient levels can
reduce generator output and cause malfunctions.
Ensure correct gas cock connection.
Install a manual cut-o valve with quick closure
manoeuvre for 90° rotation and end run stops in
the all open or all closed positions on the gas supply pipe in a visible and easily reachable position
outside the room where the appliance is installed.
N.B.: the internal gas supply system must be
built in compliance with the provisions and
regulations and all legislation in force, and any
other reference on good technique.
Fuel gas quality. e appliance has been designed to operate with combustible gas free of
impurities; otherwise it is advisable to t special
lters 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 causing problems
with boiler operation.
- 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.

1.8 HYDRAULIC CONNECTION.
Attention: in order not to void the condensation
module warranty, before making the boiler connections, carefully wash the CH 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),
sludge or other hazardous deposits.
It is recommended to prepare a filter in the
system to collect and separate any impurities
present in the system (slurry remover lter). In
order to avoid deposits, scaling and corrosion
in the central heating system, the provisions
set forth in the technical regulation in force on
water treatment in heating systems for civil use
must be respected.
Water connections must be made in a rational
way using the couplings on the boiler template.
e discharge of the boiler safety valve must
be connected to a tundish and then the waste
should be connected to the sewer. Otherwise, the
manufacturer declines any responsibility in case
of ooding if the drain valve cuts in.

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 EN 1717 on the pollution of drinking
water and in observance of local technical
regulations in force, we recommend installing
an anti-backflow 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 (CH circuit), as dened
INSTALLERUSER
in standard EN 1717.
Attention:to preserve the duration of appliance
eciency features, we recommend installation of
a suitable device for water treatment in presence of
water whose characteristics can lead to the deposit
of lime scale.
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 freezing of the liquid contained
in it. Before appliance start-up, ensure that the
condensate can be correctly removed. Aer rst
ignition, check that the drain trap is lled with
condensation (paragraph. 1.21)
Also, comply with national and local regulations
on discharging waste waters.
1.9 ELECTRIC CONNECTION.
e operations described below must be performed
aer having disconnecte d the electrical supply from
the appliance.
e electrical system must be built in compliance
with technical standards and all legislation in
force. e boiler has an IPX5D protection rating
for the entire appliance. Electrical safety of the
appliance is reached only when it is correctly
connected to an efficient 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.
Also ensure that the electrical installation corresponds to maximum absorbed power specications as shown on the boiler data-plate.
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.
The main switch must be installed outside
the rooms in a position that is indicated and
accessible.
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
connection terminal board, use a 3.15A fast fuse.
For the main power supply to the appliance,
never use adapters, multiple sockets or extension leads.
Important: if the Digital Remote Control 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.
•
Low temperature system installation. e
boiler can directly supply a low-temperature
system, limiting the value of the “P02” parameter, which denes the generator’s ow
temperature. In this situation it is good practice
to insert a safety device in series with the power
supply and boiler. is device is made up from
a thermostat with a temperature limit of 55
°C. e thermostat must be positioned on the
system ow pipe at a distance of over 2 metres
from the boiler.

CONTROLLERS.
e boiler is prepared for the application of a
cascade and zone regulator, zone manager and
external probe.
ese components are available as separate kits
to the boiler and are supplied on request.
Carefully read the user and assembly instructions
contained in the accessory kit.
• e cascade and area regulator (Fig. 1-5) is
connected to the boiler using only two wires,
powered at 230 V and allows to:
- manage a hydraulic circuit with 2 mixed
zones (mixing valve); 1 direct zone; 1 Storage
tank unit and relative pumps;
- self-diagnosis system to display any boiler
functioning anomalies;
- set two room temperature value: one for
daytime (comfort temperature) and one for
nighttime (lower temperature);
- to manage the temperature of the DHW (with
a storage tank unit);
- to manage the boiler ow temperature de-
pending on the external temperature;
- to select the desired operating mode from
the various possible alternatives for each
individual hydraulic circuit:
- permanent operation in comfort temp.;
- permanent operation in lower temp.;
- permanent operation in adjustable anti-freeze
temp.
• Zone manager (Fig. 1-6). In addition to the
functions described in the previous point, the
zone manager panel allows to control all the
important information regarding operation
of the appliance and the heating system with
the opportunity of easily intervening on the
previously set parameters without having
to go to the place where the appliance is
installed. The climate chrono-thermostat
incorporated into the zone manager 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. It also allows
to display the eective room temperature and
the external temperature (if external probe
is present). e zone manager is powered
directly by the cascade heat adjuster via 2
wires.
ermoregulation electrical connection (Fig.
1-4).
ermoregulation electrical connections must
be carried out on the boiler terminal board
eliminating jumper X40.
- Thermostat or On/Off environment
chrono-thermostat: must be connected to
clamps “E” and “F”. 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.
- Cascade and zone regulator: must be connected
through clamps 37 and 38 to clamps “M” and “O”
respecting polarity. e connection with incorrect
polarity will not damage the thermoregulator, but
will not allow it to operate.
Any thermostat or On/Off environment
chrono-thermostat must be connected to clamps
“E” and “F” eliminating jumper X40 (Fig. 1-4).
Make sure that the On/O thermostat contact
is of the “clean” type, i.e. independent of the
mains supply, otherwise the P.C.B. would be
damaged. Any cascade and zone regulator must
be connected by clamps 37 and 38 to clamps “M”
and “O” on the connecting terminal board in the
boiler, observing the poles and removing jumper
X40, (Fig. 1-4) connection with the wrong polarity
prevents the heat adjuster from working, although
it will not be damaged.
1.11 EXTERNAL TEMPERATURE PROBE.
e boiler is designed for the application of the
Room ermostat (Fig. 1-7) 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 electric connection of the external probe
must take place on clamps G and J on the connection in the boiler (Fig. 1-4).
By default, the external probe is not enabled. It is
necessary to set parameters “P14” and “P15” for
correct operation. e correlation between ow
temperature to the system and external temperature is determined by the curves represented in
the diagram (parameter “P14”) and by setting the
oset (parameter “P15”) (Fig. 1-8).
In case “P32” is bigger than “P15”, “P32” will be
the minimum limit for the set.
In case “P32” is lower than “P15”, “P32” will not
be considered.
N.B.: if the external probe is connected to the
cascade regulator, boiler parameter “P14” must
be set at “0”, and external probe control is delegated to the cascade regulator.

1.12 IMMERGAS FLUE SYSTEMS.
Immergas can supply various solutions for ueing and air supply.
Attention: the boiler must be installed exclusively with an original Immergas “Green
Range” air intake device and fumes extraction
system, as required by the standard in force.
e plastic pipes cannot be installed outdoors,
for lengths longer than 40 cm, without suitable
protection from UV rays and other atmospheric agents.
INSTALLERUSER
is system can be identied by an identication mark and special distinctive marking
bearing the note: “only for condensing boilers”.
• Conguration type B, open chamber and fan
assisted. e boiler leaves the factory with type
“B23” conguration.
Air intake takes place directly from the envi-
ronment in which the boiler is installed via
relevant slots made in the back of the boiler
and ue exhaust in the individual ue or to the
outside. Boiler with this type of conguration
are classied as type B23 (in accordance with
standard EN 297 and relative standards in
force).
With this conguration:
- air intake takes place directly from the room
in which the appliance is installed;
- the ue exhaust must be connected to its own
individual ue or channelled directly into the
external atmosphere.
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours
or substances (e.g. acid vapours, glues, paints,
solvents, combustibles, etc.), as well as dusts
(e.g. dust deriving from the working of wood,
coal nes, cement, etc.), which may be harmful for the components of the appliance and
jeopardise operation.
• Type C conguration, sealed chamber and
fan assisted. e boiler leaves the factory with
"B23" conguration, to change the conguration
of the boiler to type "C" (sealed chamber and
fan assisted), disassemble the 80 Ø adapter, the
bracket and the gasket present on the boiler
cover and install the designated ue.
• 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 section
(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 minimum inclination of 3% must be maintained
and a section clamp with pin must be installed
every 3 metres.
• Maximum extension. Each individual component has a resistance corresponding to a certain
length in metres of pipe with the same diameter
(par. 1.13). With installations that involve using
various types of parts, deduct the length of
the added part from the maximum admissible
length of the kit.
Example: if you need to add a 90° bend to
a concentric system 125 Ø you will need to
deduct 1.9 m from the maximum admissible
length.
• Positioning of the gaskets (black) for “green
range” ue extraction systems. Position the
gasket correctly (for bends or extensions) (Fig.
1-9):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for exten-
sions;
N.B.: if component lubrication (already carried
out by the manufacturer) is not sucient, remove the residual lubricant using a dry cloth,
then to ease tting coat the parts with talc,
supplied in the kit.
