VICTRIX 115 1 I
VICTRIX 115 is a wall-hung condensing, open chamber
boiler for central heating only or with sealed chamber and
fan assisted circulation. It is set-up thanks to a relevant kit
(optional) for coupling to a separate Immergas storage tank
unit for the production of DHW, which can also be coupled
to solar systems.
e boiler is type-approved for the installation inside a heating
control unit and outside the building and can be installed
individually or in cascade, i.e. installation of several boilers in
set on the same system (up to a maximum of three appliances).
To complete the installation, it is possible to use (optional)
hydraulic kits such as: ISPESL safety kit, hydraulic manifold
kit with lter, 3-way valve kit for coupling to storage tank kit,
hydraulic manifolds kit for the connection of two or three
boilers in set.
Thanks to condensation technology, VICTRIX 115 is
characterised for its high eciency and for the large modulating
eld (from 26 % to 100 % of the nominal heat output).
e boiler has heat output of 111 kW (95,460 kcal/h) and is
equipped with an innovative total premix combustion system,
which guarantees particularly low pollutant emissions and
allows functioning with methane or LPG.
Adjustment and control of the appliance are entrusted to an
electronic P.C.B. with microprocessor which, via display, shows
the functioning state of the boiler (temperatures, functioning
state, error codes, etc.).
e hydraulic circuit has a water-gas heat exchanger with
stainless steel twin coil.
e boilers are protected as per standard by an anti-freeze safety
General features.
device up to a temperature of -5°C.
e VICTRIX 115 boiler must be installed using particular
green series intake/exhaust kits in plastic and, however,
dedicated for the VICTRIX 115 boiler, whether it is installed
in individual conguration or in cascade (up to a maximum
of three appliances).
For ue gas exhaust, it is also possible to use the ducting
system (Ø 80 mm exible) . is is manufactured in plastic
and expressly designed for the Immergas condensing boiler.

Primary circuit (boiler circuit).
e primary circuit, with relative control and safety devices,
is started every time there is a central heating or anti-freeze
request.
Operation.
e heat contained in the combustion products is absorbed
by the pipes of the water-gas heat exchanger with coil inserted
in the condensation module (11) which, then gives the heat
up to the water made to circulate inside the boiler pump (4).

Primary heat exchanger
(condensation module).
It is formed from a casing that contains 18 elements with a
coil shape.
Each element is made up from 5 elliptical spirals (3).
e entire module is realised in stainless steel and its internal
part makes up the sealed combustion chamber and the upper
part the condensation chamber (4).
e lower twelve elements are aected directly by the action
of the cylindrical burner, while the six upper elements are ar-
ranged in the condensation chamber (4), which is separated
from the combustion chamber by sheet steel (see ue circuit).
To reduce head losses to a minimum and increase the ow rate
available to the system, the ow is made up from the parallel
connection of the nine elements, the return, instead is made
up from the parallel connection of the other nine elements.
e heat exchanger inlet is connected to the boiler pump ow
on which the system return NTC probe is positioned (6,)
while the output on which the system ow NTC probe (7) is
positioned, is connected to the primary circuit ow.
e primary circuit return and ow pipes are coupled using
threaded ttings with at gasket.
e over-temperature safety thermostat (1) is present on the
system ow pipe.
e ue hood (5) is connected on the upper part of the module
via a relevant sealing gasket and is xed using screws to the
support frame.
e condensate drain is also found in the lower part of the
module.
Safety devices and controls.
System pressure switch (2).
Detects the pressure inside the primary circuit.
Its seat is on the system ow pipe and is coupled to a micro
switch that prevents functioning of the burner when the pres-
sure detected is below 0.3 bar.
Prevents overheating of the main heat exchanger.
ISPESL type-approved 4 bar safety valve (3).
Prevents the safety pressure in the circuit from being exceeded
(4 bar).
It is connected via a xing tting to the door block valve (1),
which in turn is connected to the system ow pipe.
Its intervention causes water to escape from the system ow
pipe.
An extension pipe is connected to the valve (4) that ends with
a collection funnel (5).

Air-gas circuit.
e circuit consists of a total premix combustion system com-
posed of a fan (7), a pneumatic gas valve (9), a Venturi pipe
(5) and a special cylindrical burner (4) that operates inside the
condensation module.
Operation.
e fan (7) is controlled by the integrated P.C.B. that varies
its speed depending on the output requested.
Its functioning allows to withdraw combustion agent air from
the ue hood (3) which results in contact with the outdoors and
introduce it in a conduit where a Venturi pipe is inserted (5).
At the inlet to the Venturi (5) there is a positive pressure signal
(P1) variable in a directly proportional manner to the amount
of air taken in by the fan (7) and which is detected by a pressure
point connected to the pneumatic gas valve (9).
e electric power supply of the valve main coils causes both
internal shutters to open and allows the passage of gas, whose
outlet pressure is regulated by the same pneumatic valve in a
1:1 ratio to pressure “P1”.
e gas is injected at the entry of the Venturi pipes (5) through
a nozzle (6), where the premix starts with the combustion
agent air.
e mixture obtained in this way is ignited on the surface
of the cylindrical burner (4) by the discharge of the ignition
electrodes (10).
Gas valve.
e gas valve is equipped with two main coils controlled by the
integrated P.C.B. and with a pneumatic unit that modulates
the outlet gas pressure in 1:1 ratio to the pressure (P1) detected
on the inlet of the Venturi pipe.
e calibration of the ratio between the air and gas pressures
is carried out on the valve (o-set) (see gas regulations).
Electric coils (4).
ere are two ON-OFF coils that are powered (24 Vac) by an
integrated P.C.B. when the burner must be ignited.
ey are connected in series and powered by a voltage of 24
V through a connection connector (3).
Pneumatic unit (2).
Allows to vary the outlet pressure in 1:1 ratio with the pressure
(P1) detected at the inlet of the Venturi pipe that is taken back
to the valve using a small silicone pipe (1).
anks to this system, the percentages in the air-gas mixture
are maintained constant at optimal values on the entire range
of modulation, thus guaranteeing a more or less constant
combustion eciency.
e air-gas ratio calibration can be performed using the o-set
adjusting screw (2).
is is necessary only when, after having performed ue
analysis, incorrect combustion parameter values are detected
(see air-gas ratio regulation).

Fan.
It operates upstream from the combustion chamber and is
physically positioned in the lower part of the chamber itself.
It is powered with mains voltage (230 V AC) and controlled by
the integrated P.C.B. with a positive square wave signal with
variable ON-OFF (duty-cycle).
Its speed is adjusted (from about 1700 to about 5900 rpm)
depending on the power requested and is controlled using
a sensor with Hall eect, which detects the number of revs.
e fan withdraws the combustion agent air in the upper part
of the ue hood through a plastic pipe (1), which contributes
to reducing the noise and optimises burner ignition.
e variation of the air ow rate that is introduced into the
mixing pipe, leads to the change of the pressure signal (P1) at
the inlet of the Venturi pipe and allows the pneumatic valve
to regulate the pressure of the outlet gas.
Venturi.
e Venturi pipe (1) is inserted into a sealed pipe (4), inside
which the combustion agent air and the gas are mixed and
which is dierent depending whether methane or LPG is used.
e air is introduced by the fan inside the pipe, while the gas
exiting the valve is injected by a nozzle (2) in correspondence
with the Venturi pipe inlet (1).
e passage of air in the pipe creates a depression (“Venturi
eect”) which, through the holes (3) present at its base, allow
to “drag” the gas inside and to mix it with the air.
e nozzle (2) has a dierent diameter depending on whether
natural gas or LPG is used as, working with both gases with
more or less constant pressure, its section establishes the cor-
rect gas ow rate.
A pressure point is present on the end of the Venturi pipe,
through which the input signal (1) is detected.
is signal is taken back to the pneumatic gas valve via a sili-
cone pipe (5), which regulates the gas pressure.

Burner.
It is a cylindrical burner (5) made up from 2 concentric sheet
steel sections, appropriately perforated and built using special
steel, completely covered by a metal mesh and that is particu-
larly resistant to high temperatures and corrosion.
It is inserted inside the condensation module, in a sealed
combustion chamber closed by a ange (6) onto which the
burner is xed, which in the meantime guarantees its direct
connection to the air-gas mixing pipe (4).
e premixing, the lack of secondary air and the construction
features of the burner ensure high combustion eciency and
particularly reduced pollutant emissions (see technical data).
e material's high resistance to temperature, allows to work
with a very low ame at a minimum power of 29.5 kW (23,370
kcal/h) (26 % of the nominal output).
Ignition takes place by means of an integrated P.C.B. that
controls the ignition (7) and detection electrodes (9).
Ignition electrode (7).
ey are activated via the integrated P.C.B. that causes an
electric spark between two electrodes, on the contact of which
the air-gas mixture ignites.
e electrode (8) has no ceramic insulation and is connected
directly to earth (blind electrode).
ey are positioned on the left side of the burner and xed
onto the ange (6) of the same.
Detection electrode (9).
It is controlled by the integrated P.C.B. and detects burner
ignition.
It also acts as a ue safety device when any air intake problems
or problems with the evacuation of combustion products make
the burner function below minimum output.
In this case the ame block occurs due to no detection by the
electrode.
In order to protect the combustion circuit, the same type of
block prevents the module from lling with water when there
is diculty draining condensate (trap blocked, etc).
It is positioned on the bottom right side of the burner and
xed onto the ange (6) of the same.
Note: In the case of ignition block, check the distances of the
ignition and detection electrodes keeping to the heights stated
in the gure at the side.
Also check that there is no isolating waste present on the
detection electrode.

Air-gas adjustments.
e calibration of the total premix combustion system, when
necessary envisions, the adjustment of the nominal heat output
and the air-gas ratio (o-set).
Except for the regulation of the Nominal output that is also
carried out during the initial check, the two operations
are only normally requested after a gas transformation, after
extraordinary maintenance (replacement of a component of the
air-gas circuit, replacement of the integrated P.C.B. etc) or when
the appliance is not calibrated.
Adjustment of nominal and minimum heat
output.
e availability of maximum output is linked to the length of
the intake and exhaust pipes which, increasing, slightly reduces
the amount (ow rate) of inlet air and consequently also la
pressure of the burnt gas.
e boiler is calibrated as per standard for functioning with a
Ø80/125 horizontal concentric kit with length of 0.5 m and
therefore the use of the ue kit with greater or smaller head
losses requires a check and possible adjustment of the nominal
output according to the table give below.
e operation must be performed as follows and with respect
to the values stated in the heat output adjustment table:
- start the boiler in chimney sweep mode by pressing the
"MODE" and "+" keys simultaneously for 2 seconds. "H"
will appear on the display followed by a 2-gure number
indicating the temperature of the primary circuit, then check
the maximum speed (with burner on);
- after at least 5 minutes, check and modify parameter N°
22 "Max number of fan revs. in CH mode", after having
inserted the technician's code, in order the (N° of fan revs.)
value referring to the nominal output (see technical data);
- press the"MODE" and "-" keys at the same time for two
seconds. In this way the boiler is forced to minimum and
"L" appears on the display followed by a 2-gure number
indicating the temperature of the primary circuit;
- check and modify parameter N° 26 "Min number of fan revs.
in CH mode" until the (N° of fan revs.) value is obtained,
referring to minimum output (see technical data);
To exit the chimney sweep mode, press the "+" and "-" keys
at the same time for 2 seconds.
Regulation of the air-gas ratio (o-set).
e correct regulation of the air-gas ratio (1:1) takes place
in the factory and must be retouched only when carbon
dioxide (CO2) values are detected in the ue gases that are
not optimal.
With this scope, during the initial check or following ex-
traordinary maintenance interventions, ue analysis must
be performed at maximum heat output and minimum heat
output, which attests the goodness of the combustion in refer-
ence to the values indicated in the table below:
CO2 at nominal
output
CO2 at minimum
output
G 20 9.40 % ± 0.2 8.90 % ± 0.2
G 31 10.70 % ± 0.2 10.30 % ± 0.2
To carry out the control correctly and, if necessary, regulate
the air-gas ratio, proceed as follows:
DUNGS GB-GD 057 gas valve.
Calibration of the maximum CO2
- Switch the boiler on and take it to chimney sweep mode by
pressing the "MODE" and "+" keys simultaneously for two
seconds. In this way the boiler is forced to maximum and
"H" appears on the display followed by a 2-gure number
indicating the temperature of the primary circuit;
- withdraw the combustion products by inserting the analyser
probe fully home;
- check whether the value of carbon dioxide(CO2) is within
the limits indicated in the table regarding the nominal heat
output (see table above);
- if the values are incorrect, take them within the limits by
acting on the gas ow rate adjusting screws (12) of the gas
valve. By turning in a clockwise direction the CO2 value de-
creases, by turning in an anti-clockwise direction, it increases.
Calibration of the minimum CO2
- after having carried out maximum CO2 adjustment, switch
the boiler on and make it function at minimum input by
pressing the "MODE" and "-" keys simultaneously for two
seconds. In this way the boiler is forced to minimum and

Gas transformation.
e adaptation to the type of gas dierent to that for which
the boilers are prepared as per standard is performed using the
relevant kit (methane or LPG).
e transformation consists in the replacement of the burner
nozzles positioned in correspondence with the inlet of the Ven-
turi pipe and adjustment of the maximum and minimum heat
output by setting parameter N°22 "Max number of fan revs in
CH mode" and parameter N°26 "Min. number of fan revs in
CH mode"see nominal and minimum heat output regulation).
Finally, check the carbon dioxide value (CO2) at maximum
and minimum power output, which must be corrected if
necessary by regulating the o-set signal (see air-gas ration
regulation).

Condensate drain trap (4).
Collects the condensate that forms during boiler functioning
from the bottom of the module.
Its outlet is connected to the draining pipe (11) towards which
the passage of water is allowed but not the passage of combus-
tion products, which could occur following obstruction of the
evacuation pipes.
e height of the siphon water column is in fact over the pres-
sure that can be detected inside the sealed chamber (module)
with the fan at maximum speed and the evacuation pipes
blocked at functioning limits, thus preventing any leak of
combustion products through the condensate drain. At the
rst ignition ue gases may escape from the drain pipe (11),
which disappear after a few minutes of functioning when the
condensate has reached a sucient height. Whenever this
is delayed, it is good practice to ll the siphon with water
after having removed the small pipe (10) which must be re-
positioned correctly on termination of the operation.
Air-ue sample points (8-9).
ere are two sample points in the upper part of the boiler
with screw fastening, with front access, after having removed
the plastic cover and from where the combustion agent air (8)
and combustion products (9) can be withdrawn.
Flue circuit.
Operation.
e functioning of the fan positioned at the entry of the air-
gas mixing pipe, guarantees the fan-assisted expulsion of the
fumes produced by the cylindrical burner (5).
ese directly hit the rst 12 elements of the primary heat
exchanger (3) inserted in the sealed combustion chamber (6)
which has a sheet steel section on its upper part (7) that divides
it from the condensation chamber (2) and diverts the ow of
ue gases to the outside of the module.
In this way the ue gases, before entering the condensation
chamber (2), hit the last six elements (8) of the primary heat
exchanger, inside which primary circuit return water runs.
is cools the combustion products further and makes their
condensation easier before escape from the ue hood (1).
e water condensate formed inside the heat exchanger, in
the ue hood and also in the evacuation pipes ows into the
lower part of the module from where, before being drained,
is conveyed into a trap (4).
Flue hood (1).
It is connected to the upper part of the condensation module
and conveys the combustion products towards the ue gas
discharge tting present in the upper part of the appliance.
It is aected by the passage of combustion products and water
condensate formed inside it or in the exhaust pipes.
It is manufactured in plastic, resistant to the corrosive eects

(max. ue temp with ow 85 °C = 78 °C).
A ue safety thermostat (12) is present to preserve and protect
the ue hood and the ue gas exhaust pipes, which intervenes
when the temperature detected exceeds 90 °C.

Intake and exhaust systems.
(see intake and exhaust terminals instructions).
e VICTRIX 115 boilers are type-approved for installation
outside and inside a heating control unit.
e "VICTRIX 115" boiler leaves the factory in "B23" (open
chamber and fan assisted) conguration. To change the con-
guration of the boiler to type "C" (open chamber and fan
assisted), disassemble the Ø 80 adapter, the bracket and the
gasket present on the boiler cover, in this way the relevant kits
can be used.
For correct installation of the VICTRIX 115 boiler the specic
range of intake and exhaust pipes must be used, which has
been designed to be coupled exclusively to the VICTRIX
115 condensing boiler range.
e “GREEN SERIES ” ue kit for VICTRIX 115 is made
in plastic (PPS = self-extinguishing polypropylene) suitable for
resisting the corrosive action of the acid condensate as it is
specic for this type of appliance.
Conguration with sealed chamber and fan-
assisted circulation (type C).
Intake.
e depression created by fan functioning allows the input of
combustion agent air via the external concentric hole (Ø 125)
of the concentric adapter (2) connected onto the ue hood (1),
which is connected via a plastic pipe to the fan.
In this way, the air intake takes place from the environment
outside where the boiler is installed.
Exhaust.
In the same way, the discharge of combustion products takes
place by making use of the narrowest hole (Ø 80) present on
the ue hood (1), which via the concentric adapter (2) is con-
nected to the concentric intake/exhaust pipes.
In this way, the ue gases are discharged outside of the environ-
ment where the boiler is installed.

The VICTRIX 115 boilers leave the factory in the B23.
conguration.
Intake.
e depression created by fan functioning allows the input of
combustion agent air via the external concentric hole (Ø 125) of
the fumes hood (1), which is connected via a plastic pipe to the fan.
In this way, air intake takes place directly from the environment
where the boiler is installed via the relevant slot made on the back
of the boiler and laterally to the valves support sheet steel present
in the lower part of the boiler.
Exhaust.
In the same way, the discharge of combustion products takes
place by making use of the narrowest hole (Ø 80) present on
the ue hood (1), which via the adapter (2) is connected to the
exhaust pipes.
In this way, the ue gases are discharged outside of the environment
where the boiler is installed.
Exhaust kit.
e kits with relative accessories allow the use of three ue exhaust
systems (Ø 80) and a system for ducting Ø 80 exible hoses.
For that regarding the head losses relative to each accessory, for the
various combinations that can be performed, see the instructions
relative to the exhaust terminals.
Coupling between the various accessories(bends, extensions,
terminals) is the push-tting type and sealing is assured by relevant
silicon lip seal gaskets in EPDM peroxide resistant to the action
of the condensate.
