INSTALLATION
1.1 INSTALLATION
RECOMMENDATIONS.
e Magis Victrix ErP boiler has been designed
uniquely for wall-installation, for the production of domestic hot water for household use
and the like; also, combined with the Immergas
heat pump, it heats and cools the rooms (cooling is performed by the heat pump only). e
heat pump is controlled directly by the boiler
circuit board.
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.
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. 1-1).
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
sealed chamber boilers for air intake 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.
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 with an obstructed conveying
system (the safety valve must be conveyed away
by a draining funnel), or if there are leaks from
the hydraulic connections; on the contrary, 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 and contact an
authorised company (e.g. the Authorised 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 regulations:
- this boiler can be installed outdoors in a
partially protected area. A partially protected
area is one in which the appliance 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 in places with a re risk is prohibited (for example: garages, closed parking
stalls), gas appliances and relative ue ducts,
ue exhaust pipes and combustion air intake
pipes.
- Installation is prohibited on the vertical
projection of cooking hobs.
- Installation is also forbidden in places/rooms
that constitute common parts of apartment
buildings such as stairs, cellars, entrance
halls, attics, los, escape routes, etc. unless
otherwise provided by local regulations.
Attention: wall mounting of the boiler must
guarantee stable and ecient support for the
generator
e plugs (standard supply) are to be used only in
conjunction with the mounting brackets or xing
template to x 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.
N.B.: the hex head screws supplied in the blister
pack are to be used exclusively to x the relative
mounting bracket to the wall.
ese boilers are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a central heating
system and hot water circuit suited to their
performance and capacity.
- In the event of installing a heat pump to
integrate the gas appliance, the installation
company must also be in possession of the
requirements of the legislation in force on environmental protection relating to uorinated
greenhouse gasses.

1.3 ANTIFREEZE PROTECTION.
Minimum temperature -3°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 4°C.
In these conditions the boiler is protected against
freezing to an ambient temperature of -3°C.
Minimum temperature -15°C. In the event the
boiler is installed in a place where the temperature falls 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
MAINTENANCE TECHNICIAN
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 (anti-freeze kit) comprising two
electric heating elements, the relevant cables
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 -3°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 stand-by ( )
- the boiler is not in anomaly conditions (parag.
2.6);
- 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.
NOTE: 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.

1.5 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 1/2”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
name plate). If dierent, the appliance must be
converted for operation with the other type of
gas (see converting appliance for other gas types).
INSTALLERUSER
The dynamic gas supply (methane or LPG)
pressure must also be checked according to the
type used in the boiler, which must comply with
the technical standards in force, as insucient
levels can reduce generator output and cause
malfunctions.
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 technical
standards in force.
Fuel gas quality. e appliance was 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 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.
1.6 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 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),
slurry or other hazardous deposits.
Water connections must be made in a rational
way. The boiler safety valve outlet must be
connected to a draining funnel. 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 the technical regulation in force in
relation to the pollution of drinking water, we
recommend installing the IMMERGAS antibackow kit to be used upstream of the cold
water inlet connection of the boiler. It is also
recommended that the heat transfer uid (e.g.
water + glycol) entered in the primary circuit
of the boiler (heating circuit), complies with the
local regulations in force.
Attention: to preserve the duration and the efciency 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.
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 ignition, ensure
that the condensate can be correctly removed.
Aer rst ignition, check that the drain trap is
lled with condensate (para. 1.20). Also, comply
with national and local regulations on discharging waste waters.
Condensate collection tray drainage. e boiler
in the lower part is equipped with a tting for
draining condensate which may possibly form
due to the circulation of chilled water. Before
appliance start-up, ensure that an excessive production of condensate can be expelled properly.

1.7 ELECTRIC CONNECTION.
e appliance has an IPX5D protection degree,
electrical safety of the appliance is reached 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.
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 overvoltage category.
To protect from possible dispersions of DC
voltage one must provide a type A dierential
safety device.
When replacing the power supply cable, contact
a qualied rm (e.g. the 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
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.
• Comando Amico Remoto remote control
electrical connection V2 (CARV2). e boiler
only functions if connected to the Comando
V2
Amico Remoto remote control
per standard with the boiler. e CAR
, supplied as
V2
must
be connected to the + and - IN clamps and to
clamps 44 and 41 on the P.C.B. (in boiler) observing the polarity and using the connection
cable that comes out of the boiler and which is
appropriately marked (Fig. 1-4). Connection
with the wrong polarity prevents the CAR
from operating although without damaging
it. e connection to the boiler is made using
wires with a minimum section of 0.50 mm
and maximum section of 2.5 mm2 and with a
maximum length of 50 metres.
• External temperature probe electrical connection. e boiler only works if it is connected
to the external temperature probe supplied
as per standard with the boiler. Refer to the
relative instruction sheet for positioning of
the external probe. e probe allows to automatically decrease the maximum system ow
temperature when the outside temperature
increases, in order to adjust the heat supplied to
the system according to the change in external
temperature. e correlation between system
ow temperature and external temperature
is determined by the parameters set in menu
“M5” under item “P66” according to the curves
represented in the diagram (Fig. 1-5). e electric connection of the external probe must be
made on clamps 38 and 39 on the boiler P.C.B.
(Fig. 1-4).
• Heat pump electrical connection. e boiler
can be combined with an Immergas heat pump
which must be connected to the boiler as shown
in the wiring diagram (Fig. 1-4).
One must congure some parameters on the
heat pump remote panel:
“Assistance Menu -> Zone Denition”:
Remote control enabling: NO
Room thermostat enabling: SI
V2
- “Zone Set Point” menu
Set mandata riscaldamento

Set mandata rarescamento
Set the ow parameters according to your
requirements.
N.B.: hot/cold and on/o request of the heat
pump will be managed by the boiler and not
from the heat pump's remote panel.
Congure the boiler parameters as indicated in
paragraph “circuit board programming” (Par.
3.9).
Important: it is mandatory to prepare separate
lines with dierent supply voltage; it is essential
to separate the low voltage connections from the
230 V ones. All boiler pipes must never be used
for earthing the electrical or telephone system.
Ensure elimination of this risk before making the
boiler electrical connections.

1.8 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 device and
fumes extraction system made of plastic, as
required by the regulations in force.
e plastic pipes cannot be installed outdoors,
INSTALLERUSER
for tracts longer than 40 cm, without suitable
protection from UV rays and other atmospheric agents.
is system can be identied by an identication mark and special distinctive marking
bearing the note: “only for condensing 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 the gaskets (black) for “green
range” ue systems. Position the gasket correctly (for bends and extensions) (Fig. 1-6):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for exten-
sions;
N.B.: if component lubrication (already car-
ried 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.
MAINTENANCE TECHNICIAN
• 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 minimum inclination of 3% must be maintained and
a section clip with pin must be installed every
3 metres.

direct air intake (Fig. 1-7) and fumes exhaust in
a single ue 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
(outside);
- the fumes 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. 1-8). Remove
the two plugs and the gaskets present from
the two lateral holes with respect to the central
one. Now cover the right intake hole using the
relevant plate, xing it onto the le 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 sheet steel plate and
tighten by means of the straps present in the
kit, making sure to block the 4 gasket aps. Fit
the male end (smooth) of the exhaust terminal

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: Couple the pipe or
elbow with the male side (smooth) in the female side (with lip seal) to the end 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)
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, Ø 80/125 and separator Ø 80/80
concentric intake/ exhaust kits. Refer to the

Separator kit Ø 80/80. is kit allows air to come
in from outside the building and the fumes to exit
from the chimney or ue through divided ue
exhaust and air intake pipes. Combustion products are expelled from pipe (S) (in plastic, so as
to resist acid condensate). Air is taken in through
duct (A) for combustion (this is also in plastic).
e intake pipe (A) can be installed either on the
right or le hand side of the central exhaust pipe
(S). Both ducts can be routed in any direction.
• Kit assembly (Fig. 1-18): install ange (4) on
the central hole of the boiler, positioning gasket
(1) 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

(3 and 4). Fit the intake terminal (6) with the
male side (smooth) in the female side of the
bend (5) up to the end stop, ensuring that the
internal and external wall sealing plates are
tted. Fit the exhaust pipe (9) with the male
side (smooth) to the female side of the bend
(5) up to the end stop; making sure that the
internal wall sealing plate has been tted, this
will ensure sealing and joining of the elements
making up the kit.
• Installation clearances (Fig. 1-19). e minimum installation clearance measurements of
the Ø 80/80 separator terminal kit have been
stated in some limit conditions.
• Extensions for separator kit Ø 80/80. The
maximum vertical straight length (without
bends) that can be used for Ø 80 intake and
exhaust pipes is 41 metres, regardless from
whether they are used for intake or exhaust.
e maximum horizontal straight length (with
bend in suction and in exhaust) that can be
used for Ø 80 intake and exhaust pipes is 36
metres, regardless from whether they are used
for intake or exhaust.
N.B.: to favour the removal of possible condensate forming in the exhaust pipe, tilt the pipes
towards the boiler with a minimum slope of
1.5% (Fig. 1-20).

1.14 ADAPTOR C9 KIT INSTALLATION.
is kit allows an Immergas boiler to be installed
in "C
" conguration, with combustion air intake
93
directly from the sha where the ue gas exhaust
is, obtained by means of a ducting system.
System composition.
e system must be combined with the following
components (sold separately) to be functional
and complete:
- kit C93 Ø 100 or Ø125 version
- ducting kit Ø 60 or Ø 80
INSTALLERUSER
- fumes exhaust kit Ø 60/100 or Ø 80/125 congured according to the installation and type
of boiler.
Kit Assembly.
- Mount the components of kit "C9" on the door
(A) of the ducting system (Fig. 1-22).
- (Version Ø 125 only) mount the anged adaptor (11) interposing the concentric gasket (10)
on the boiler, tting it with the screws (12).
- Mount the ducting system as described in the
relative instructions sheet.
- Calculate the distances between the boiler drain
and the bend of the ducting system.
- Prepare the boiler ue system, making sure that
the internal pipe of the concentric kit is tted
properly in the bend of the ducting system
(quota "X" g. 1-23), while the external pipe
must be tted on the adaptor until it stops (1).
N.B.: to encourage the removal of possible
condensate forming in the exhaust pipe, tilt
the pipes towards the boiler with a minimum
slope of 1.5%.
- Mount the cover (A) complete with adaptor (1)
and caps (6) on the wall and assemble the ue
system to the ducting system.
N.B.: (version Ø 125 only) before assembly
check the gaskets are in the right position. In
the event 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 common
or industrial talc.
Once all components have been assembled properly, the exhaust fumes will be expelled via the
ducting system; the combustion air for normal
boiler operation will be aspirated directly by the
sha (Fig. 1-23).
Technical data.
- e dimensions of the shas must ensure a
minimum gap between the outer wall of the
smoke duct and the inner wall of the sha: 30
mm for circular section shas and 20 mm in
the event of a square section sha (Fig. 1-21).
- Maximum 2 changes of direction are allowed
on the vertical section of the ue system with
a maximum clearance angle of 30° with respect
to the vertical.
- e maximum vertical extension using a Ø 60
ducting system is 13 m, the maximum extension includes 1 bend Ø 60/10 at 90°, 1 m of
horizontal pipe 60/100, 1 90° ducted bend Ø
60 and the roof terminal for ducting.
To determine the C
tions other than that described (Fig. 1-23)
one must consider that 1 metre of ducted pipe
according to the indications described has a
resistance factor equal to 4.9.
- e maximum vertical extension using a Ø 80
ducting system is 28 m, the maximum extension includes 1 adapter 60/100 to 80/125, 1 87°
bend Ø 80/125, 1 m of horizontal pipe 80/125,
1 90° ducted bend Ø 80 and the roof terminal
for ducting.
To determine the C93 ue system in congura-
tions other than that described (Fig. 1-23) one
must consider the following pressure drops:
- 1 m of concentric pipe Ø 80/125 = 1 m of
ducted pipe;
- 1 87° bend = 1.4 m of ducted pipe;
Consequently one must subtract the equivalent
length of the part added to the 28 m available.

1.15 DUCTING OF FLUES OR
TECHNICAL SLOTS.
Ducting is an operation through which, via
the introduction of one or more relevant pipes,
one achieves a system for the evacuation of the
combustion products of a gas appliance, made up
from the coupling of an existing or new ducting
pipe with a chimney, ue or technical slot (also
in new buildings) (Fig. 1-24). Ducting requires
ducts declared to be suitable for the purpose by
the manufacturer, following the installation and
user instructions, provided by the manufacturer
and the requirements of the standards in force.
Immergas ducting system. e Ø 60 rigid and
Ø 80 exible “Green Range” ducting systems must
only be used for domestic use and with Immergas
condensing boilers.
In any case, ducting operations must respect
the provisions contained in the standard and in
current technical regulations. e instructions in
the project or technical report must likewise be
followed, in cases provided for by the standard
and current technical regulations. e system or
components of the system have a technical life
complying with current standards, provided that:
- it is used in average atmospheric and environ-
mental conditions, according to current regulations (absence of fumes, dusts or gases that can
alter the normal thermophysical or chemical
conditions; existence of temperatures coming
within the standard range of daily variation,
etc.).
- Installation and maintenance must be per-
formed according to the indications supplied
by the manufacturer and in compliance with
the provisions in force.

appliances with a heat input range from 4 to 35
kW, provided the conditions as per the current
technical standards are respected.
1.19 SYSTEM FILLING.
Once the boiler and the heat pump have been
connected, ll the system via the lling valve (Fig.
1-27 and 2-6). Filling is performed at low speed
to ensure release of air bubbles in the water via
the boiler, heat pump and heating system vents.
e boiler incorporates an automatic vent valve tted on the circulator pump and one on the system
vent tank. Check if the cap is loose. Open the radiator
vent valves.
Close radiator vent valves when only water
escapes from them.
Close the lling cock when the boiler pressure
gauge indicates approx. 1.2 bar.
N.B.: during these operations activate the automatic vent functions featured on the boiler
(active upon initial ignition) and on the heat
pump (see relative instructions booklet). Vent
the boiler circulation pump by loosening the front
cap and keeping the motor running. Tighten the
cap aer the operation.
1.21 GAS SYSTEM STARTUP.
To start up the system, refer to the technical
standard in force.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or open ames;
- bleed all air from the pipelines;
- check that the internal system is properly sealed
according to the specications set forth by
technical regulations in force.
1.22 BOILER START UP IGNITION.
To commission the boiler (the operations listed
below must only be performed by qualied personnel and in the presence of professionals only):
- check that the internal system is properly sealed
according to the specications set forth by
technical regulations in force;
- make sure that the type of gas used corresponds
to boiler settings;
- Check that there are external factors that may
cause the formation of fuel pockets;
- switch the boiler on and check correct ignition;
- make sure that the gas ow rate and relevant
pressure values comply with those given in the
manual (Par. 3.20);
- ensure that the safety device intervenes in the
event of gas supply failure and check the relative
intervention time;
- check the intervention of the main switch
located upstream from the boiler and in the
boiler;
- check that the intake/exhaust concentric terminal (if tted) is not blocked.
e boiler must not be started up even if only
one of the checks should be negative.
1.20 CONDENSATE TRAP FILLING.
On rst lighting of the boiler combustion products may come out the condensate drain; aer a
few minutes’ operation check that this no longer
occurs. is means that the trap is lled with

condensate to the correct level preventing the
passage of combustion products.

1.23 CIRCULATION PUMP.
e boilers are supplied with 2 circulator pumps,
both equipped with speed regulator.
ese settings are suitable for most systems.
• Boiler circulator pump. e boilers are sup-
plied with a variable speed circulator pump.
When the boiler operates in heating mode, the
pump speed is dened according to the “P57”
parameter setting in the M5 menu (Par. 3.9), in
domestic hot water mode the circulator pump
always runs at maximum speed.
During the heating stage the Auto and Fixed
operating modes are available.
NOTE.: the ∆T can be controlled compatibly
with the characteristics of the central heating
system and of the boiler.
• Auto: automatic pump speed. In this mode one
can choose between the “Proportional head”
and “Constant ∆T” option.
- Proportional head (∆T = 0): the circulator
speed varies according to the power emitted by the burner, the greater the power the
greater the speed. Within the parameter one
can also adjust the pump operating range,
by setting the maximum speed (adjustable
from 100 % ÷ 30 %) and the minimum speed
(adjustable from 30% to the max. set speed).
- ∆T Constant (∆T = 5 ÷ 25 K): the pump
speed varies to maintain the ∆T constant
between the system ow and return according to set value K. Within the parameter one
can also adjust the pump operating range,
by setting the maximum speed (adjustable
from 100 % ÷ 30 %) and the minimum speed
(adjustable from 30% to the max. set speed).
• Fixed (100 % ÷ 30 %): in this mode, the pump
operates at constant speed, the operating range
is dened between minimum (30 %) and maximum (100 %).
Pump release. If, aer a prolonged period of
inactivity, the circulation pump is blocked,
unscrew the front cap and turn the motor sha
using a screwdriver. Take great care during this
operation to avoid damage to the motor.
• System circulator pump. e system circulator
pump controls the room heating or cooling requests downstream of the hydraulic manifold.
In fact, the pump is equipped with electronic
control that allows to set advanced functions..
For proper operation one must select the most
suitable type of operation for the system and
select a speed between 2 and 7.
- Constant head program (P C) (4 fig.
1-25). e circulator pump maintains the
pressure level (head) constant as the system
heat demand decreases (ow rate reduction).
With these settings, the circulator pump is
suitable for all oor systems where all the
circuits must be balanced for the same drop
in head. One can select the power level from a
minimum one to a maximum one by turning
the selector switch clockwise in the relative
power scale.
- Proportional head program (P V) (3 g.
1-25). is allows the pressure level (head)
to be proportionally reduced as the system
heat demand decreases (flow rate reduction). anks to this function, the electric
power consumption of the circulator pump
is reduced further: the energy (power) used
by the pump decreases according to the pressure level and ow rate. With this setting, the
pump guarantees optimal performance in
most heating systems, proving particularly
suitable in single-pipe and two-pipe installations. Any noise of the water ow in the pipes,
valves and radiators is eliminated by reducing
the head. Optimal conditions for thermal
comfort and acoustic well-being. One can select the power level from a minimum one to a
maximum one by turning the selector switch
counterclockwise on the relative power scale.
Adjustments. Turn the selector and set it on
the desired curve to adjust the circulator pump.
Automatic vent function (1 g. 1-25). e
circulator pump is equipped with a function
that activates its operation for 10 minutes,
alternating the speed between minimum and
maximum, so that the air contained in the circulator pump is expelled by the air vent valve.
Diagnostics in real time: a light ring (2 g.
1-25) supplies, with dierent colours, information relating to the circulator pump operating
status, see table below.

Once the boiler is switched on, the display indicates all operating information
• Summer ( ): in this mode the boiler only
operates for domestic hot water heating.
During domestic hot water heating, “DHW
ON” appears on the display (24) on the status
indicator (6) and at the same time as the burner
ignites, the ame presence indicator switches
on (8) with the relative power scale and the indicator (9 and 7) with the instantaneous outlet
temperature from the primary heat exchanger.
Summer mode operation with domestic hot
water heating
• Winter ( ): in this mode the boiler func-
tions both for heating domestic hot water and
heating the environment. Depending on the
climatic conditions and on the set-point, the
control electronics establish whether it is more
convenient to use the boiler, the heat pump or
both to heat the environment.
- Room heating with boiler: during the request
“CH ON” appears on the display (24) on the
status indicator (6) and at the same time as
the burner ignites the ame presence indicator switches on (8) with the relative power
scale and the indicator (9 and 7) with the
instantaneous outlet temperature from the
boiler. During the heating stage, if the water
temperature is sucient to heat the system,
the boiler can operate just with the activation
of water circulation.

- Room heating with heat pump: during the
request “CH ON” appears on the display (24)
on the status indicator (6) and at the same
time as the heat pump starts-up the indicator
switches on (26) as well as the indicator (7)
with the instantaneous outlet temperature
from the boiler.
Winter operation mode with room central
heating with heat pump
• External probe operation (part. 18). The
boiler flow temperature for room central
heating is managed by the external probe depending on the external temperature measured
(Parag. 1.7 and par. 3.9 under item “P66”). One
can modify the operation curve by acting on
the central heating selector of the CAR
V2
(see
relative manual).
From this moment the boiler functions automatically. With no demand for heat (central heating
or domestic hot water production) the boiler
goes to “standby” function, equivalent to the
boiler being powered without presence of ame.
N.B.: it is possible that the boiler may start-up
automatically if the antifreeze function is activated (13). Moreover, the boiler can function
for a brief period of time aer a withdrawal of
domestic hot water in order to take the domestic
hot water temperature back into temperature.
• Air conditioning ( ): in this mode the boiler
works both for domestic hot water heating as
well as cooling, the boiler manages solely the
system circulator pump and the heat pump for
room cooling starts to work depending on what
has been set on the CARV2.
During cooling “COOLING” appears on the
display (24) on the status indicator (6) and at
the same time when the heat pump starts-up
the indicator switches on (26) as well as the
indicator (7) with the instantaneous outlet temperature from the boiler. e ow temperature
will be xed at the “cooling set point” (SPC)
value set on the heat pump.

2.8 BOILER SHUTDOWN
Switch the boiler o by pressing the “ ” button, disconnect the onmipolar switch outside of
the boiler and close the gas cock upstream of the
appliance. Never leave the boiler switched on if
le unused for prolonged periods.
2.9 RESTORE CENTRAL HEATING
SYSTEM PRESSURE.
Periodically check the system water pressure.
e boiler pressure gauge should read a pressure
between 1 and 1.2 bar.
INSTALLERUSER
If the pressure falls below 1 bar (with the circuit
cold) restore normal pressure via the valve located
at the bottom of the boiler (Fig. 2-6).
N.B.: close the valve aer the operation.
If pressure values reach around 3 bar the safety
valve may be activated.
In this case, remove water from an air vent valve
of a radiator until 1 bar is reached or ask for assistance from an authorised company.
If frequent pressure drops should occur, ask an
authorised company for assistance to eliminate
the possible system leakage.
2.10 SYSTEM DRAINAGE.
To drain the boiler, use the special draining
valve (Fig. 2-6).
Before draining, ensure that the lling valve is
closed.
2.11 ANTIFREEZE PROTECTION.
e “Magis Victrix ErP” series boiler features
an anti-freeze function that lights the burner
automatically when the temperature falls below
4°C (standard protection up to minimum temperature of -3°C). All information relative to
the anti-freeze protection is stated in Par. 1.3. In
order to guarantee the integrity of the appliance
and the domestic hot water heating system in
zones where the temperature falls below zero,
we recommend the central heating system is
protected using anti-freeze liquid and installation
of the Immergas Anti-freeze Kit in the boiler. In
the case of prolonged inactivity (second case),
we also recommend that:
- disconnect the electric power supply;
- the central heating circuit and boiler domestic
hot water circuit must be drained. In systems
that are drained frequently, lling must be carried out with suitably treated water to eliminate
hardness that can cause lime-scale.
2.12 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the boiler casing. Never use abrasive or powder
detergents.
2.13 DECOMMISSIONING.
In the event of permanent shutdown of the
boiler, contact an authorised company for the
suitable procedures and also ensure the electrical, water and fuel supply lines are shut o and
disconnected.

N.B.: maintenance operations must be carried
out by an authorised company (e.g. Authorised
Aer-Sales Technical Assistance Service).
- Smell of gas. Caused by leakage from gas circuit
pipelines. Check sealing eciency of gas intake
circuit.
- Repeated ignition blocks. No gas, check the
presence of pressure in the network and that
the gas adduction cock is open. Incorrect
adjustment of the gas cock, check the correct
calibration of the gas valve.
- Irregular combustion or noisiness. It may be
caused by: a dirty burner, incorrect combustion
parameters, intake-exhaust terminal not correctly installed. Clean the above components
and ensure correct installation of the terminal,
check correct setting of the gas valve (O-Set
setting) and correct percentage of CO2 in ue
gas.
- Frequent interventions of the overheating
safety thermostat. It can depend on the lack
of water in the boiler, little water circulation
in the system or blocked pump. Check on the
manometer that the system pressure is within
established limits. Check that the radiator
valves are not closed and also the functionality
of the pump.

- Noise due to air in the system. Check opening of the special air vent valve cap (Part. 28
Fig. 1-27). Make sure the system pressure and
expansion vessel pre-charge values are within
the set limits; e factory-set pressure values of
the expansion vessel must be 1.0 bar, the value
of system pressure must be between 1 and 1.2
bar.
- Noise due to air inside the condensation
module. Use the manual air vent valve (Part.
14 Fig. 1-27) to eliminate any air present in the
condensation module. When the operation has
been performed, close the manual vent valve.
- System low circulation. Check the boiler,

3.5 CONVERTING THE BOILER TO
OTHER TYPES OF GAS.
If the boiler has to be converted to a dierent gas
type to that specied on the data plate, request
the relative conversion kit for quick and easy
conversion.
e gas conversion operation must be carried
out by an authorised company (e.g. Authorised
Technical Aer-Sales Service).
To convert to another type of gas the following
operations are required:
- disconnect the appliance;
- replace the nozzle located between the gas pipe
and gas/air mixing sleeve (Part. 7 Fig. 1-27),
MAINTENANCE TECHNICIAN
taking care to disconnect the appliance during
this operation;
- re-power the appliance;
- calibrate the number of fan revolutions (parag.
3.6):
- adjust the correct air/gas ratio (parag. 3.7);
- seal the gas ow rate regulation devices (if set-
tings are modied);
- after completing the conversion, apply the
sticker, contained in the conversion kit, near
the data nameplate. Using an indelible marker
pen, delete the data relative to the old type of
gas.
ese adjustments must be made with reference
to the type of gas used, following that given in
the table (Par. 3.20).
3.6 CALIBRATION OF NUMBER OF FAN
REVS.
Attention: verication and calibration is neces-
sary, in the case of transformation to other types
of gas, in the extraordinary maintenance phase
with replacement of the PCB air/gas circuit components or in the case of installations with ue
extraction systems, with horizontal concentric
pipe measuring more than 1 metre.
e boiler heat output is correlated to the length
of the air intake and ue exhaust pipes. is
decreases with the increase of pipe length. e
boiler leaves the factory adjusted for minimum
pipe length (1m). It is therefore necessary, especially in the case of maximum pipe extension, to
check the ∆p gas values aer at least 5 minutes
of the burner operating at nominal heat output,
when the temperatures of the intake air and exhaust ue gas have stabilised. Adjust the nominal
and minimum heat output in the domestic hot
water and central heating modes according to
the values in the table (Par. 3.19) using the differential manometers connected to the ∆p gas
pressure points (15 and 16 Fig. 1-27).
Access the congurations menu (Par. 3.9) and
adjust the ignition power “P50”, while within
item “SERVICE” adjust the following parameters:
3-5
- boiler maximum heat output “P62”;
- boiler minimum heat output “P63”;
- maximum central heating output “P64”;
- minimum central heating output “P65”;

CO2 in the ue gases the technician must insert
the sampling probe to the bottom of the sample
point, then check that the CO2 value is that specied in the table, otherwise adjust the screw (12
Fig. 3-4) (gas ow rate regulator).
To increase the CO2 value one must turn the
adjustment screw (12) clockwise for gas valve
8205 and counterclockwise for gas valve 848 and
vice versa is one wants to decrease it.
At every adjustment variation on the screw 12 it
is necessary to wait for the boiler to stabilise itself
at the value set (about 30 sec.).
3.8 CHECKS FOLLOWING
CONVERSION TO ANOTHER TYPE
OF GAS.
Aer making sure that conversion was carried
out with a nozzle of suitable diameter for the
type of gas used and the settings are made at the
correct pressure, check that the burner ame is
not too high or low and is stable (does not detach
from burner);
N.B.: all boiler adjustment operations must be
carried out by a qualied company (e.g. Authorised Aer-Sales Assistance).

3.10 CENTRAL HEATING OPERATION IN
COMBINATION WITH THE HEAT
PUMP.
Following a request during the room heating
mode, the electronics decide, according to the
external temperature, whether to activate the
heat pump, or (with cold or high temperatures)
the boiler (g. 3-6):
Boiler and heat pump can even operate simultaneously: in fact, if only the heat pump is active,
but it cannot bring the water to temperature
within a certain time, the boiler starts in parallel.
e boiler electronics select which heat source
to be used according to the combination of
“MAGIS” parameters.
e heating mode is equipped with a timer that
prevents the generators from restarting too frequently. One can modify this value via parameter
“P69”. e heat pump is equipped with its own
timer that that prevents the frequent start-ups,
set at a xed value (3 minutes).

3.11 "CHIMNEY SWEEP" FUNCTION.
If this function is activated it takes boiler functioning to the adjustable power of the central
heating selector switch.
In this state all adjustments are excluded and only
the safety thermostat and the limit thermostat
remain active. To activate the chimney sweep
function press the Reset button "C" for 8 to 15
seconds in absence of domestic hot water and
heating requests. Its activation is signalled by
the relative symbol (22 Fig. 2-1). is function
allows the technician to check the combustion
INSTALLERUSER
parameters. Aer the checks deactivate the function, switching the boiler o and then on again
using the Stand-by button.
3.12 PUMP ANTIBLOCK FUNCTION.
e boiler features a function that starts the
pump at least once every 24 hours for 30 seconds
in order to reduce the risk of the pump becoming
blocked due to prolonged inactivity.
3.13 THREEWAY ANTIBLOCK
FUNCTION.
Both in “domestic hot water” and in “domestic
hot water-central heating” phase the boiler is
equipped with a function that starts the threeway motorised group 24 hours aer it was last
in operation, running it for a full cycle so as to
reduce the risk of the three-way group becoming
blocked due to prolonged inactivity.
3.14 RADIATORS ANTIFREEZE
FUNCTION.
If the system return water is close to freezing,
the boiler starts up until it reaches a safety
temperature.
3.15 P.C.B. PERIODICAL SELFCHECK.
During functioning in heating mode or with
boiler in standby, the function activates every 18
hours aer the last boiler check/power supply. In
case of functioning in domestic hot water mode
the self-check starts within 10 minutes aer the
end of the withdrawing in progress, for duration
of approx. 10 seconds.
N.B.: during self-check, the boiler remains o.
3.16 AUTOMATIC VENT FUNCTION.
In the case of new heating systems and in particular mode for oor systems, it is very important
that dearation is performed correctly. To activate
function “F8” press buttons “A and B” at the same
time (Fig. 2-1) for 5 seconds with the boiler in
MAINTENANCE TECHNICIAN
stand-by. The function consists of the cyclic
activation of the pump (100 s ON, 20 s OFF)
and the 3-way valve (120 s domestic hot water,
120 s central heating). e function ends aer
18 hours or by switching the boiler on using the
ignition button “
”.
3.17 SOLAR PANELS COUPLING
FUNCTION.
e boiler is set-up to receive pre-heated water
from a solar panels system up to a maximum
temperature of 65 °C. If used with greater
temperatures, it is recommended to install a
mixing valve on the hydraulic circuit upstream
of the boiler. Set the “P71” function on “P71.1”
(Par. 3.9).
When the boiler inlet water is at a temperature
that is equal or greater than that set by the domestic hot water selector switch “SET”, the boiler
does not switch on.
3.18 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
e following checks and maintenance should
be performed at least once a year.
- Clean the ue side of the heat exchanger.
- Clean the main burner.
- If deposits are detected in the combustion
chamber one must remove them and clean the
heat exchanger coils using nylon or sorghum
brushes; it is forbidden to use brushes made of
metal or other materials that may damage the
combustion chamber itself.
- Check the integrity of the insulating panels
inside the combustion chamber and if damaged
replace them.
- Visually check for water leaks or oxidation
from/on fittings and traces of condensate
residues inside the sealed chamber.
- Check contents of the condensate drain trap.
- Via the condensate drain cap check that there
are no residues of material that clog condensate
passage; also check that the entire condensate
drain circuit is clear and ecient.
In the event of obstructions (dirt, sediment,
etc.) with consequent leakage of condensate
in the combustion chamber, one must replace
the insulating panels.
- Check that the burner seal gaskets and the lid
are intact and perfectly ecient, otherwise
replace them. In any case the gaskets must be
replaced at least every two years, regardless of
their state of wear.
- Check that the burner is intact, that it has no
deformations or cuts and that it is properly
xed to the combustion chamber lid; otherwise
it must be replaced.
- Visually check that the water safety drain valve
is not clogged.
- Check that, aer discharging system pressure
and bringing it to zero (read on boiler pressure
gauge), the expansion vessel pressure is at 1.0
bar.
- Check that the system static pressure (with
system cold and aer relling the system by
means of the lling valve) is between 1 and 1.2
bar.
- Visually check that the safety and control
devices have not been tampered with and/or
shorted, in particular:
- temperature safety thermostat;
- Check the condition and integrity of the electrical system and in particular:
- supply voltage cables must be inside the
fairleads;
- there must be no traces of blackening or
burning.
- Check ignition and operation.
- Check correct calibration of the burner in
domestic hot water and central heating phases.
- Check the operation of the appliance control
and adjustment devices and in particular:
- intervention of the main electrical switch on
the boiler;
- system regulation probes intervention;
- domestic hot water control thermostat inter-
vention.
- Check sealing eciency of the gas circuit and
the internal system.
- Check the intervention of the device against
no gas ionisation ame control. e relative
intervention time must be less than 10 seconds.
N.B.: in addition to yearly maintenance, one
must also check the thermal system, with frequency and procedures that comply with the
indications of the technical regulations in force.
