Special hydraulic kits are available as optionals to complete
the installation such as the ISPESL safety kit, the distribu-
tion manifold with lter kit, the 3-way diverter valve kit for
coupling the storage tank and the hydraulic manifolds kits for
connecting two or three boilers in cascade.
anks to the condensation technology, VICTRIX 50 is distin-
guished for its high operating performance and wide modula-
tion range (from 20 % to 100 % of its nominal output).
e boiler has a heat output of 50 kW (43,000 kcal/h) and
features an innovative total premix combustion system that
ensures minimal pollution emissions. It can work with natural
gas or LPG.
e appliance is regulated and controlled by means of a mi-
croprocessor controlled p.c.b. which, via a display, shows the

Primary circuit (boiler circuit).
e primary circuit with relevant control and safety devices
is triggered each time there is a request for central heating
or antifreeze.
Operation.
e heat contained in the ue produced by combustion is ab-
sorbed by the pipes of the coil water-gas exchanger tted in the
condensation module (13), which, in turn, transfers it to the
water circulating inside thanks to the boiler circulator (28).

Primary exchanger (condensation module).
It consists of a casing containing 11 coil shaped elements.
Each element is made of 5 elliptic pipe spirals (3).
e whole module is made of stainless steel and the inner part
comprises a sealed combustion chamber and condensation
chamber (2).
e rst eight elements are involved directly in the action of the
cylindrical burner, tted to the front, while the last three are
inside the condensation chamber which is separated from the
combustion chamber by a metal plate (see the ue circuit).
To minimise load losses and increase the ow available for
the system, the delivery consists of the parallel connection of
the rst six elements while the return consists of the parallel
connection of the last ve elements.
e exchanger inlet is connected to the boiler circulator deliv-
ery on which the system return NTC probe is positioned (5)
while the outlet, on which the system delivery (6) NTC probe
is positioned, is connected to the primary circuit delivery.
readed ttings and a at seal are used to couple the delivery
and return pipes of the primary circuit.
e overheating safety thermostat (1) is installed on the system
delivery pipe.
e draught diverter (4) is connected at the back by means of
a seal locked by a metal ring.
e condensate drain is also found in the lower part.
To ease the escape of any air bubbles still present in the coils,
there is a manual air vent (7) in the upper part of the mod-
ule.
Safety devices and controls.
System pressure switch (2).
is switch detects the pressure inside the primary circuit.
It is housed on the delivery manifold body and coupled to a
microswitch that prevents the burner working when pressure
is below 0.3 bar.
It prevents the main exchanger from overheating.
ISPESL type approved 4 bar safety valve (3).
It prevents the safety pressure from being exceeded in the
circuit (4 bar).
It is located at the front of the delivery manifold body to
which it is coupled.
When this valve trips it causes water to come through the sys-
tem delivery pipe to which an extension pipe (4) is connected
that ends with a collection funnel (5).

Air-gas circuit.
e circuit consists of a total pre-mix combustion system
comprising a fan (7), a pneumatic type gas valve (9), a Venturi
pipe (5) and a special cylindrical burner (4) that works inside
the condensation module.
Operation.
e fan (7) is controlled by the microprocessor driven p.c.b.
that varies speed according to the output required.
By means of this fan, combustion air is taken from the draught
diverter (3), which is in contact with outside and sent through
a duct where a Venturi pipe (5) is installed.
A positive pressure signal (P1) is located at the Venturi (5) inlet
and varies in a way directly proportional to the quantity of air
extracted by the fan (7) and which is detected by means of a
pressure point connected to the pneumatic gas valve (9).
e energising of the main valve coils causes both internal
shutters to open and the gas to ow through, whose outlet
pressure is regulated by the same pneumatic valve with a 1:1
ratio at pressure “P1”.
rough nozzle (6), gas is injected at the inlet of the Venturi
pipe (5) where pre-mixing begins with the combustion air.
e resulting mix is ignited on the cylindrical burner surface
(4) by a spark of the ignition electrodes (10).
Gas valve.
e gas valve features two main coils controlled by the inte-
grated board and a pneumatic control unit that modulates the
exiting gas pressure at a 1:1 ratio at pressure (P1) detected at
the Venturi pipe inlet.
e ratio between air and gas pressures (o-set) are set on this
valve (see gas regulations).
Electrical coils (4).
Two ON-OFF type coils that are powered by the integrated
board (24 V DC) when the burner has to be ignited.
ey are connected in series and energised at a voltage of 24
V through a connector (3).
Pneumatic unit (2).
Outlet pressure can be varied with this unit at a 1:1 ratio at
pressure (P1) detected at the Venturi pipe inlet which is re-
turned to the valve through a silicone pipe (1).
anks to this system, the percentages in the air-gas mix remain
constant at optimum values on the entire modulation eld thus
ensuring an almost constant combustion performance.
By means the o-set screw (2) the air-gas ratio can be adju-
sted.
is is only necessary if, after having analysed the ue,
incorrect combustion values are found (see air-gas ratio ad-
justment).

Fan.
is operates upstream from the combustion chamber and it is
physically positioned at the bottom of the sealed chamber.
It is controlled by the integrated board with a positive square
wave signal with a variable ON-OFF (duty-cycle) ratio.
Its speed is adjusted (from about 1250 to about 5200 rpm) ac-
cording to the output required and is controlled by means of
a Hall eect sensor which reads the rpm.
e fan extracts the combustion air from the top of the draught
diverter through a plastic pipe (1) that helps reduce noise and
optimises burner ignition.
Variations in the ow of air entering the mixing duct results
in a variation in the pressure (P1) signal at the inlet of the
Venturi pipe and enables the pneumatic valve to regulate
exiting gas pressure.
Venturi.
e Venturi pipe (1) is tted in a sealed duct (6) inside which
the combustion air and gas are mixed.
e air is driven to the bottom of the duct by the fan, while
the exiting gas from the valve is injected at the Venturi pipe
(1) inlet by a nozzle (2).
e transit of air in the pipe creates vacuum (“Venturi eect”)
which, through the 4 holes (3) in the base, “drags” the gas
inside and mixes it with the air.
e nozzle (2) diers in diameter according to whether natural
gas or LPG is used; in fact working with both gases at a more or
less constant pressure, its section determines correct gas ow.
At the end of the Venturi pipe is a pressure pick-up point where
the input signal (P1) is read.
is signal is conveyed to the pneumatic valve regulating the
gas pressure via a silicone pipe.

Burner.
is is a cylindrical burner (5) consisting of three concentric
plates appropriately perforated and made of a special stainless
steel highly resistant to high temperatures and corrosion.
It is tted inside the condensation module, in a sealed com-
bustion chamber closed by a ange (4) to which the burner is
secured and which simultaneously ensures direct connection
with the air-gas mix duct (6).
Pre-mixing, the absence of secondary air and the construction
characteristics of the burner ensure high combustion perform-
ance and very low pollutant emissions (see technical data).
anks to the high resistance to temperatures of the materi-
als used, it is possible to operate with a very low ame up
to a minimum output of 10.0 kW (8,600 kcal/h) (20 % of
nominal output).
An integrated electronic board sees to ignition and controls
both the ignition (7) and detection (9) electrodes.
Ignition electrodes (7).
ey are controlled by the integrated electronic board which
produces an electrical charge between them that ignites the
air-gas mix.
Electrode (8) has no ceramic insulation and is earthed directly
(blind electrode).
ey are positioned on the right of the burner and secured
on the ange (4).
Detection electrode (9).
It is controlled by the integrated electronic board and detects
burner ignition.
It also acts as a ue safety device when any air intake or combus-
tion product extraction problems cause the burner to operate
below minimum output.
In this case, in fact, we have a ame-stop condition because
there is no detection by the electrode.
To protect the combustion circuit, this same stoppage prevents
the module from lling with water whenever there are conden-
sation drainage problems (siphon blockage, etc.).
It is xed on the left of the burner ange (4).
Note: in case of ignition block it’s required to check the distances
of the ignition electrodes and of the detection electrodes sticking
to the values shown in the gure at this side.
Check moreover that there are no insulating cinders on the de-
tection electrodes.

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).
With exception for the adjustment 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 0.5m and
therefore the use of the ue kit with greater or lower 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, if necessary, modify the
value of parameter N° 22 "Max number of fan rpm in CH
mode", after having inserted the code reserved for the tech-
nician, until obtaining the value (N° of fan rpm) referring
to the nominal output (see technical data);
- press the "MODE" and "-" keys simultaneously 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, if necessary, modify the value of parameter N°
26 "Min number of fan rpm in CH mode" until reaching
the value (N° of fan rpm) referring to the 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 fumes that are
not optimal.
With this scope, during the initial check or following extra-
ordinary maintenance interventions, ue analysis must be
performed at maximum heat output and minimum heat
output, which attests the goodness of the combustion in
reference to the values indicated in the table below:
G 31

10,10 % ± 0,2
9,32 % ± 0,2
12,30 % ± 0,2
10,60 % ± 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 o-set adjusting screws (12) of the gas valve.
By turning in a clockwise direction the CO2value decreases,
by turning in an anti-clockwise direction, it increases.

Calibration of the minimum CO2.
- after having carried out maximum CO2adjustment, 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
"L" 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 minimum heat
output (see table above);
- if the values are incorrect, restore them to the limits by
turning the gas valve’s oset adjustment screw (3).
By turning the screw clockwise the CO2value increases while
it decreases by turning the screw counter clockwise.
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
Venturi pipe and adjustment of the maximum and minimum
heat output by setting parameter N°22 "Max number of fan
rpm in CH mode" and parameter N°26 "Min. number of
fan rpm 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 fumes,
which could occur following obstruction of the evacuation
pipes.
e height of the column of water in the siphon is in fact
greater than the pressure detected inside the sealed chamber
(module) with the fan at maximum speed and the evacuation
pipes blocked at functioning limits.
is, however, prevents the draining of combustion products
into the sewers.
On commissioning fumes may escape from the exhaust pipe
(11) which disappear after a few minutes of functioning when
the condensate has reached a sucient height. If this should
take too long, ll the siphon with water after having removed
the cap (10), which must be re-positioned correctly at the end
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.
Operating.
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 eight elements of the primary heat
exchanger inserted in the sealed combustion chamber (6) which
has a sheet steel section on its base (7) that divides it from the
condensation chamber (2) and diverts the ow of fumes to the
outside of the module.
In this way the ue gases, before entering the condensation
chamber (2), hit the last three elements (3) of the heat exchan-
ger, 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 discharged,
is conveyed into a trap (4).
Flue hood (1).
It is connected to the rear part of the condensation module
and conveys the combustion products towards the drain tting
present in the upper part of the appliance.
It is aected by the passage of fumes and water condensate
formed inside it or in the exhaust pipes.
It is constructed in plastic, resistant to the corrosive eects of
the condensate and can work to a temperature of 130 °C (max.
ue temp with ow 85° C = 78° C).
A ue safety thermostat is inserted onto the condensation
module (12), to protect the ue hood (1) and which intervenes
when the temperature detected on the condensation module
exceeds110° C.

e “VICTRIX 50” boiler leaves the factory with a “B23”
type conguration (fan-assisted open chamber); to change the
conguration into a “C” type (fan-assisted sealed chamber) you
have to remove the 80 Ø adapter, the bracket and the seal on
the boiler cover so you can then use the specic kits.
For a correct installation of the VICTRIX 50 boiler it is neces-
sary to use the new and specic set of air inlet and exhaust
pipes that have been designed to be used exclusively with the
VICTRIX 50 series of condensation boilers.
e ue pipes of the “GREEN SERIES” are made of plastic
(PPS = self-extinguishing polypropylene) suitable for resisting
the corrosive action of acid condensation as they are specic
for this kind of appliance.
Fan-assisted sealed chamber conguration
(type C).
Air inlet.
e vacuum that is created when the fan is working allows
the inlet of combustion air through the external concentric
hole (125 Ø) of the concentric adapter (2) slotted into the
draught diverter (1) which is connected to the fan with a
plastic pipe.
In this way air inlet of the air occurs outside the room where
the boiler is installed.
Exhaust.
Likewise, the discharge of the products of combustion occurs
by exploiting the narrowest hole (80 Ø) on the draught diverter
(1) which, by means of the concentric adapter (2), is coupled
to the concentric air inlet and exhaust ues.
In this way the ue are expelled outside the room where the
boiler is installed.

Air inlet and exhaust kits.
e kits with relative accessories permit use of two concentric
systems.
As regards the load losses relating to each accessory and the
various possible combinations see the instructions concerning
the air inlet and exhaust end pieces.
e coupling of the various accessories (curves, extensions, end
pieces) are of the push tting and sealing is ensured by EPDM
peroxide lip seals resistant to the action of condensate.

Fan-assisted open chamber conguration.
(type B23).
e VICTRIX 50 boilers leave the factory in the B23 con-
guration.
Air inlet.
e vacuum created by the fan permits the inlet of combus-
tion air through the external concentric hole (125 Ø) of the
draught diverter (1) which is connected to the fan with a
plastic pipe. us the air inlet of air occurs directly from the
room where the boiler is installed through slits at the back of
the boiler and on the side of the valve supporting plate at the
bottom of the boiler.
Exhaust.
Likewise, the products of combustion are expelled through
the narrowest hole (80 Ø) on the draught diverter (1) which
is connected to the exhaust pipes with the adapter (2). us
the ue are discharged outside the room where the boiler is
installed.
Exhaust kit.
e kits with relative accessories permit the use of three 80 Ø
ue discharge systems and a exible 80 Ø ducting system.
As regards the load losses relating to each accessory and the
various possible combinations see the instructions concerning
the exhaust end pieces.
e coupling of the various accessories (curves, extensions, end
pieces) is of the push tting and sealing is ensured by EPDM
peroxide lip seals resistant to the action of condensation.
