• VICTRIX 50 code 3.015276
NOTE: to correctly install the boiler, use the "Green series" Immergas
air intake/fumes exhaust kit dedicated to the VICTRIX 50 boiler in
both the single and series (bank) congurations.
VICTRIX 50 is the new wall-mounted condensing boiler for
room heating alone. It is pre-engineered for operation both
independently and in series (up to 3 appliances connected),
with the advantage of providing a globally higher efciency at lower running costs. Condensing technology allows
particularly high efciency ratings to be achieved (4 stars,
as established by Directive 92/42/EEC). VICTRIX 50's high
power is ideal when it comes to heating domestic systems
that have to deal with large volumes (semi-detached houses,
small condominiums and apartment blocks) and for commercial and industrial uses. If a single boiler is installed, an
external three-way valve can be connected so as to use it
with a separate water heater and produce domestic hot water. A hydraulic manifold can also be connected to boost the
circulation in the system, thus making it versatile and quick
to install. When operation is in series, several distribution
manifolds can be connected by means of threaded mechanisms. The special environment-friendly burner guarantees
particularly low polluting emissions (the boiler belongs to the
most environment-friendly class established by the European
standards, i.e. class 5).

7 THERMOREGULATION SYSTEMS (OPTIONAL)
8 SERIES AND ZONE REGULATOR (CODE 3.015244)
Single modular generators or ones installed in series need an
adequate thermoregulation system able to dialogue with the
boiler in a simple way and meet the most varied operating
requirements.
This is why the VICTRIX 50 generator can be tted with a
series of accessories able to optimize the climatic adjustments
made to the entire system.
In short, VICTRIX 50 can be installed with two types of
system:
• In series (with the system divided into one or more zones),
using the series regulator with either the zone controller or
modulating ambient thermostat that regulates the heat in
the individual zones.
• Individually (with the system divided into zones) using the
series regulator with either the zone controller or modulating
ambient thermostat that regulates the heat in the individual
zones. A commercially available timer-thermostat can be
used if there is only one zone.
The Series and zone regulator allows the user to control, monitor and program the operating sequence of the generators
connected. The regulator can be set-up and programmed
using parameters that guarantee ideal temperature conditions at all times of the day and night and throughout every
day of the week for both the heating system and domestic
hot water system (when VICTRIX 50 is used in conjunction
with a water heater). The series regulator can be tted into a
support afxed to a wall.
8.1 SPECIFICATIONS
The electrical connections are made with 2 wires powered at
230V (1.5 mm2 ) in diameter.
2 BUS data cables up to 50 meters in length are used to
connect to the boiler, allowing the device to:
• control up to three zones (2 of which mixed if necessary)
and a separate water heater unit. Since up to 5 series regulators can be installed (of which only one, the so-called
Master, will be connected to the boiler board), systems with
up to a total 15 zones (of which 10 mixed if necessary) and
5 separate water heater units can be controlled;
• enter two ambient temperature values, one for the daytime
(comfort temp.) and one for the night (lower temp.);
• control the temperature of the domestic hot water (in
conjunction with a water heater Unit);
• select the operating mode for the heating and hot water
production functions of each individual hydraulic circuit:
- comfort temperature mode,
- low temperature mode,
- adjustable antifreeze temperature mode;
• control the boiler delivery temperature according to the outdoor temperature (in conjunction with the external probe),
with climatic curve settings;
• obtain information about the system:
- temperature of the system,
- operating mode,
- meter data,
- timer program,
- pump operating status,
- variable input values and operation;
• enter the operating parameters:
- operating times,
- operating mode,
- domestic hot water,
- direct, mixed 1, mixed 2 circuits,
- date and time;
• display operating faults with their relative error codes by
means of the check-control system;
• display the date, time, day of the week and temperature of
the generator.

VICTRIX 50
9 ZONE CONTROLLER (CE 3.015264)
The zone controller only operates in conjunction with the
series regulator. Besides the functions described for the series
thermoregulator, it allows the user to keep all the important
information concerning the operation of the appliance and
heating system under control and particularly ready to hand.
This means that the previously set parameters can be easily
modied without having go go to the place where the series
regulator is installed. the climatic timer-thermostat built
into the remote control panel allows the system's delivery
temperature to be adapted to the effective needs of the place
being heated so as to obtain the required ambient temperature
with the utmost precision and, thus, with evident savings in
running costs. The controller also allows the ambient temperature and effective outdoor temperature to be displayed (this
latter if the external probe is installed). The zone controller is
powered by the series thermoregulator by means of 2 BUS
data cables.
9.1 SPECIFICATIONS
2 BUS data cables up to 50 meters in length are used to
connect to the series and zone regulator, allowing the device
to:
• control up to one zone;
• enter two ambient temperature values, one for the daytime
(comfort temp.) and one for the night (lower temp.);
• control the temperature of the domestic hot water (in
conjunction with a water heater Unit);
• select the operating mode for the heating and hot water
production functions of each individual hydraulic circuit:
- comfort temperature mode,
- low temperature mode,
- adjustable antifreeze temperature mode;
• control the boiler delivery temperature according to the outdoor temperature (in conjunction with the external probe),
with climatic curve settings;
• obtain information about the system:
- temperature of the system,
- operating mode,
- meter data,
- timer program,
- pump operating status,
- variable input values and operation;
• enter the operating parameters:
- operating times,
- operating mode,
- domestic hot water,
- direct, mixed 1, mixed 2 circuits,
- date and time;
• display operating faults with their relative error codes by
means of the check-control system;
• display the date, time, day of the week and temperature of
the generator.

VICTRIX 50
11 EXTERNAL PROBE (CODE 3.015266)
The external probe allows the maximum temperature delivered to the system to be automatically lowered or raised as
the outdoor temperature rises or lowers, thus adapting the
heat supplied to the system to suit the outdoor temperature
variations.
The probe is connected straight to the boiler's terminal board
with two wires. Once connected, it always acts even without
the thermoregulation kit.
10 MODULATING AMBIENT THERMOSTAT (CODE 3.015245)
The modulating ambient thermostat (not a conventional
On/Off model) only operates in conjunction with the series
regulator and allows the user to regulate the ambient temperature of one of the zones into which the system is divided
(both in individual and series installations).
The regulation curve of the ambient temperature in the zone
can be modied by means of the series regulator itself.
The modulating ambient thermostat is powered by the series
thermoregulator via 2 BUS data cables.
10.1 SPECIFICATIONS
2 BUS data cables up to 50 meters in length are used to
connect to the series and zone regulator, allowing the device
to:
• control up to one zone;
• vary the ambient temperature of the zone;
• select the operating mode for the zone heating function:
- xed comfort temperature mode,
- xed low temperature mode,
- operation with the timer program.

“GREEN SERIES” INTAKE/EXHAUST KIT FOR VICTRIX 50
16 TYPE OF INSTALLATION
VICTRIX 50 boilers are approved for installation both inside
and outside the heat plant.
The "VICTRIX 50" boiler leaves the factory in the "B23" conguration (open chamber and forced draught). To change the
boiler conguration to type "C" (sealed chamber and forced
draught), dismantle the Ø 80 adapter, the plate and the seal
on the boiler cover so that the relative Ø 80/125 kits can be
used.
To correctly install the boiler, use the special Immergas
"Green" series air intake/fumes exhaust kit since the materials,
components and accessories have been specically designed
for this type of appliance.
The kits are made of plastic material so as to provide high resistance to corrosion and make them very quick and functional
to install, also thanks to the push-in connection mechanism
and the silicone seals.
The boiler classication varies when the type of installation
changes:
Configuration type C with sealed chamber and forced
draught.
The boiler is installed using the relative Ø 80/125 concentric
kits after having disassembled the Ø 80 adapter, the plate and
the seal from the boiler cover.
Air is thus inlet and fumes exhausted directly outside the
building.
The following can be used as concentric intake/exhaust kit:
Concentric Ø 80/125 horizontal kit Code 3.015242;
Concentric Ø 80/125 vertical kit Code 3.015243.
Configuration type B23 with open chamber and forced
draught.
The boiler is installed using the Ø 80 adapter provided with the
boiler as part of the standard supply and to which the relative
Ø 80 fumes exhaust kit should be connected.
The air is taken straight from the room in which the boiler
is installed, while the fumes are exhausted through the ue
or straight outdoors. This means that the installation must
only be made in conjunction with one of the following fumes
exhaust kits:
Ø 80 horizontal terminal kit for wall-mounted exhausts
Code 3.015255;
Ø 80 horizontal kit for ue exhausts
Code 3.015254;
Ø 80 vertical terminal kit for direct exhausts
Code 3.015256.
When installed singly, again in the "B23" conguration, VICTRIX
50 can also be used in conjunction with the Ø 80 hose pipe
system for condensing boilers.
This method is particularly suitable for stacks or ues (or
technical apertures) that are not perfectly straight and where
a rigid piping system could be difcult to install.
When installed in series in heat plants or technical rooms,
special fumes manifolds can be used for exhausting into ues
equipped with non-return devices (air-locks) to prevent the
boiler's products of combustion from interfering with the
combustion circuits of other boilers that are off.

VICTRIX 50
Each component of the air intake/combustion product
exhausting system possesses a resistance factor calculated by means of tests and given in the following tables.
The resistance factor of each individual component is a
dimensionless magnitude. This parameter is conditioned by
the temperature of the uid and, thus, varies depending on
whether the component in question is installed in the air
intake section or in the part where the combustion products
are exhausted.
Each component also has a resistance corresponding to a
certain length in meters of pipe of the same diameter: this
is the so-called “equivalent length” obtained from the ratio
between the relative resistance factors.
To identify the link between these two parameters in the best
possible way, rst consider an 80 mm diameter 90° elbow
as an example. It possesses a 2.6 resistance factor on the
exhausting part. However, if a pipe 80 mm in diameter and 1
meter in length is taken as a reference, it will be found to have
a 1.2 resistance factor on the exhausting part. The equivalent
length “Leq” of the considered elbow will therefore be:
Leq = 2,6 : 1.2 = 2.1 m of Ø 80 mm pipe (on the exhaust).
Very briey, the loss of head of an 80 mm diameter 90° elbow
is the same as that of a 2.1 m length straight pipe of the same
diameter (installed on the fumes outlet).
All boilers have a maximum resistance factor of 100, calculated experimentally. The maximum tolerated resistance
factor corresponds to the resistance found with the maximum
tolerated pipe length.
All this information allows calculations to be made in order to
ascertain whether the various congurations of the system are
feasible. In short, to ensure that the appliance operates in the
correct way, every air intake/combustion product exhaust
conguration must have a maximum overall resistance
factor of 100. This limit must not therefore be exceeded
when the resistance factors of the individual components
used are added together.
The resistance factors and equivalent losses in meters are
given in the catalogue in relation to:
- the “Green series” fumes exhaust pipes to use when making
the combustion-aiding air supply pipes and fumes exhaust
pipes (i.e. the pipes that connect the appliance and the
stack/ue/ducted pipe);
- the components to use for making the Ø 80 mm hose
pipe ducting system for condensing boilers, described
further on in this brochure (meaning the mainly vertical
pipe specically installed to collect the eliminate the products of combustion as well as being able to withstand
their components and condensation and t for installation
in an already existing and not perfectly straight stack/ue/
technical aperture).

23 Ø 80 HOSE PIPE DUCTING SYSTEM
The Immergas Ø 80 mm hose pipe ducting system for already
existing stacks comprises a series of components, considered
as single kits, which can be assembled to suit the specic
installation requirements. This system is supplied in a conguration that includes an 87° rising inlet elbow which then
proceeds vertically with the Ø 80 hose pipe and the outlet
terminal. The ducted pipe can be inspected through a ap in
the part where it connects to the boiler.
The kit consists of a 12 m length hose pipe. If the pipe
is too short, it can be joined to other pieces by means of
adapters.
A centering spacer with expanding ns must be added every
so often in order to ensure that the pipe keeps to the middle
of the stack.
The maximum length that can be covered with this type of
piping system is 30 m (approx.).
This length is obtained considering:
- 1 (one) Ø 80 mm 90° elbow for connection to the boiler
(on the outlet);
- 1 m of Ø 80 mm discharge pipe;
- two direction offshoots in the vertical section;
- the Ø 80 mm bearing elbow;
- the vertical terminal kit for Ø 80/125 pipes.
It is important to note that:
- only one appliance can be used with this system;
- the system can only be used with condensing applian-
ces.
