INSTALLATION
1.1 INSTALLATION RECOMMENDATIONS.
Only professionally qualied heating/plumbing
technicians are authorised to install Immergas
gas appliances.
Victrix Pro 55 1A boilers in individual or cascade
installation can be installed outdoors or in a
suitable room.
e installation must comply with all laws and
standards in force.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and components) as well as their eventual replacement
with appliances and/or equivalent components.
Installation must be carried out according to
regulation standards AS/NZS 5601 or Local
Authority laws.
Attention: these boilers must be used to heat
rooms and the like; they are for heating water
to a temperature lower than boiling point at
atmospheric pressure. erefore, they must be
connected to a heating system that is suitable for
their performance and their power.
Attention: Immergas declines all liability for
damages caused by boilers removed from other
systems or for any non-conformities of such
equipment.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
Hunt Heating immediately.
Packaging materials (staples, nails, plastic bags,
polystyrene foam, etc.) constitute a potential hazard and must be kept out of the reach of children.
Keep all ammable objects away from the appliance (paper, rags, plastic, polystyrene, etc.).
In the event of malfunctions, faults or incorrect
operation, turn the appliance o and contact the
installer before contacting Hunt Heating.
Do not attempt to modify or repair the appliance alone.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
- Installations MUST comply with AS/NZS
5601 and Local laws. Use AS/NZS 5601 as a
guide for specic locations see below.
• Installation regulations: these boilers are not
in any way designed for installation on bases
or oors (Fig. 1-1), but exclusively for wall
installation. e wall surface must be smooth,
without any protrusions or recesses enabling
access to the rear part. Wall mounting of the
boiler must guarantee stable and ecient support for the boiler. 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.
e boilers must be installed in a way to prevent
collisions and tampering.
N.B.: the hex head screws supplied in the blister pack are to be used exclusively to x the
mounting bracket to the wall.
N.B.: it is recommended to use a suitable ‘Safe
Tray’, if boiler is installed in a lo, above a ceiling, or any area where damage can be caused
by water.

minimum ceiling height of 2.3 m.
e aforementioned heights allow for correct
installation of the appliances and observe the
technical regulations in force.
Position of the appliances in the room.
Individual appliance: the distances between
any external point of the boiler and the vertical
and horizontal walls of the room must allow
accessibility to the regulation, safety and control
elements for routine maintenance.
Multiple appliances, not interconnected, but installed in the same room: the minimum distance
to maintain between several boilers installed
on the same wall must be 200 mm, in order to
allow accessibility to the regulation, safety and
control elements and routine maintenance of all
appliances installed.
Cascade installation: e instructions for correct
cascade installation are provided in the respective documents or on the www.immergas.com
MAINTENANCE TECHNICIAN
website in the high power section.
1.3 AERATION AND VENTILATION OF THE INSTALLATION ROOMS.
e rooms must have one or more permanent
openings for aeration on external walls. The
openings used for aeration can be protected
using metal grills, meshes and/or rain-proof ns
as long as the net aeration surface is not reduced.
Aeration for installation in outdoor places. e
minimum free surfaces, in relation to the overall
heat input must not be below:
a) above-ground rooms (S ≥ Q x 10)
S > 515 cm
(ex: to install 3 Victrix Pro 55 1A in cascade,
the minimum surface is 515 x 3 = 1545 cm
2
for every Victrix Pro 55 1A
2
b) basements and underground rooms up to a
height of -5 m from the reference surface (S
≥ Q x 15).
S > 775 cm
(ex: to install 3 Victrix Pro 55 1A in cascade,
the minimum surface is 775 x 3 = 2325 cm
2
for every Victrix Pro 55 1A
2
c) underground rooms at quota between -5 m
and -10 m from the reference surface (S ≥ Q
x 20 with a minimum of 5000 cm
S > 5000 cm
2
for all congurations
In all cases each opening must not have a net
surface area less than 100 cm
2
).

.
Attention: in the case of installation of appliances
powered with gas with greater density than 0.8
(L.P.G.) in outdoor places, above-ground, at least
2/3 of the aeration surface must be ush with the
oor, with a minimum height of 0.2 m.
e aeration openings must be at least 2 m for
heating capacities not exceeding 116 kW and 4.5
m for higher heating capacities, cavities, depressions or openings communicating with rooms
below the walkway surface or draining ducts.
Aeration for installation in building also destined for other use or in places inserted in the
volume of the building served. e aeration
surface must not be less than 3000 cm
2
in the case
of natural gas and must not be less than 5000 cm2
in the case of L.P.G..
e installation must comply with the requirements of all relevant codes and standards.
1.4 OUTDOOR INSTALLATION.
e boiler has an IPX5D electric insulation rating and can also be installed outdoors, without
additional protections.
Attention: all optional kits that can be potentially
connected to the boiler must be protected on the
basis of their electrical protection rating.
1.5 ANTIFREEZE PROTECTION.
Minimum temperature -5°C. e boiler comes
standard with an anti-freeze function that activates the pump and burner when the system
water temperature in the boiler falls below 5°C.
e anti-freeze function is only guaranteed if:
- the boiler is correctly connected to gas and
electricity power supply circuits;
- the boiler is powered constantly;
- Main switch is inserted;
- the boiler is not in no ignition block
- the boiler essential components are not faulty.
In these conditions the boiler is protected against
freezing to an ambient temperature of -5°C.
)
Minimum temperature -15°C. If the boiler is
installed in a place where the temperature falls
below -5°C and in the event there is no gas (or
the boiler goes into failed ignition block), the
appliance can freeze.
To prevent the risk of freezing follow the
instructions below:
)
- Protect the central heating circuit from freezing
by inserting a good-quality antifreeze liquid
into this circuit, which is specially suited
for central heating systems and which is
manufacturer guaranteed not to cause damage
to the heat exchanger or other components of
the boiler.
e antifreeze liquid must not be harmful to
one’s health.
. e instructions of the manufacturer of this
liquid must be followed scrupulously regarding
the percentage necessary with respect to the
minimum temperature at which the system
must be kept. An aqueous solution must be
made with a potential water pollution class of 2
(EN 1717:2002 or local regulations 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 supplier’s
instructions.
- Protect the condensate drain trap and relative
drain against freezing by using an accessory
supplied on request (anti-freeze kit) comprising
two electric resistances, the relevant cables and
a control thermostat (carefully read the installation instructions contained in the accessory
kit pack).
Boiler anti-freeze protection is thus ensured only if:
- the boiler is correctly connected to electricity
power supply circuits;
- main switch is inserted;
- the anti-freeze kit components are ecient.
In these conditions the boiler is protected against
freezing to temperature of -15°C.
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.

1.7 CONNECTION. Gas connection.
Our boilers are designed to operate with natural
gas (G20) and L.P.G. Supply pipes must be the
same as or larger than the 3/4” G boiler tting.
N.B.: the gas supply pipe must be suitably dimensioned according to current regulations in
order to guarantee correct gas ow to the burner
even in conditions of maximum generator output
and to guarantee appliance eciency (technical
specications). e connection to the gas supply
must conform to standards.
Before connecting the gas line, carefully clean
inside all the fuel feed system pipes to remove any
residue that could impair boiler eciency. Also
make sure the gas corresponds to that for which
the boiler is prepared (see boiler data-plate). If
dierent, the appliance must be converted for
operation with the other type of gas (see converting appliance for other gas types). e dynamic
gas supply (methane or L.P.G.) pressure must
also be checked according to the type used in
the boiler, which must comply with EN 437 and
relative attachments and with the local technical
regulations in force, as insucient levels can
reduce generator output and cause malfunctions.
Ensure correct gas cock connection.
Install a manual cut-o valve with quick closure
manoeuvre for 90° rotation and end run stops in
the all open or all closed positions on the gas supply pipe in a visible and easily reachable position
outside the room where the appliance is installed.
N.B.: the internal gas supply system must be
built in compliance with the provisions and
regulations and all legislation in force, and any
other reference on good technique.
Fuel gas quality. e appliance has been designed to operate with combustible gas free of
impurities; otherwise it is advisable to t special
lters upstream of the appliance to restore the
purity of the fuel.
Storage tanks (in case of supply from LPG
depot).
- New LPG storage tanks may contain residual
inert gases (nitrogen) that degrade the mixture
delivered to the appliance causing problems
with boiler operation.
- Due to the composition of the LPG mixture,
layering of the mixture components may occur
during the period of storage in the tanks. is
can cause a variation in the heating power of
the mixture delivered to the appliance, with
subsequent change in its performance.
1-3
1.8 HYDRAULIC CONNECTION.
Attention: in order not to void the condensation
module warranty, before making the boiler connections, carefully wash the CH system (pipes,
radiators, etc.) with special pickling or descaling
products to remove any deposits that could compromise correct boiler operation.
A treatment of the heating and water 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. scale),
slurry or other hazardous deposits.
It is recommended to prepare a filter in the
system to collect and separate any impurities
present in the system (slurry remover lter). In
order to avoid deposits, scaling and corrosion
in the central heating system, the provisions
set forth in the technical regulation in force on
water treatment in heating systems for civil use
must be respected.
Water connections must be made in a rational
way using the couplings on the boiler template.
e discharge of the boiler safety valve must
be connected to a tundish and then the waste
should be connected to the sewer. Otherwise, the
manufacturer declines any responsibility in case
of ooding if the drain valve cuts in.
Cold Water connection.
Attention: Filling the system, Hunt Heating
recommends the use of Auto fill valves sold
as an optional extra. Once satisfactory system
pressure is achieved, Auto ll valve MUST BE
TURNED OFF.
MAINTENANCE TECHNICIAN

Attention: Immergas and Hunt Heating declines
all liability in the event of damage caused by the
inclusion of automatic lling.
In order to meet the system requirements established by EN 1717 and in observance of local
technical regulations in force on the pollution
of drinking water, we recommend installing
an anti-backflow kit to be used upstream of
the cold water inlet connection of the boiler.
We also recommend using a category 1, 2 or
3 heat transfer uid (ex: water + glycol) in the
boiler’s primary circuit (CH circuit), as dened
INSTALLERUSER
in standard EN 1717.
Attention: to preserve the duration of appliance
eciency features, we recommend the installation
of a suitable device for water treatment in presence
of water whose characteristics can lead to the
deposit of lime scale.
Condensate drain. To drain the condensate
produced by the appliance, it is necessary to
connect to the drainage system by means of
acid condensate resistant pipes, with an internal
Ø of at least 13 mm. e system connecting the
appliance to the drainage system must be carried
out in such a way as to prevent freezing of the
liquid contained in it. Before appliance ignition,
ensure that the condensate can be correctly
removed. N.B.: pre-ll the condense trap with
water before operating the boiler.
Also, comply with national and local regulations
on discharging waste waters. In the event condensate is not discharged into the wastewater
drainage system, a condensate neutraliser must
be installed to ensure compliance with the parameters established by the legislation in force.
1.9 ELECTRIC CONNECTION.
e operations described below must be performed
aer having disconnected the electrical supply from
the appliance.
e electrical system must be built in compliance
with technical standards and all legislation in
force. e boiler has an IPX5D protection rating
for the entire appliance. Electrical safety of the
appliance is reached only when it is correctly
connected to an efficient earthing system as
specied by current safety standards.
Attention: Immergas S.p.A. and Hunt Heating
decline 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 a power
cable and Australian plug type 1 conforming
to AS3112. The power supply cable must be
connected to a 230V ±10% / 50Hz mains supply
respecting L-N polarity and earth connection;
, this network must also have a multi-pole circuit breaker with class III over-voltage category.
The main switch must be installed outside
the rooms in a position that is indicated and
accessible.
When replacing the power supply cable, contact a
qualied company.
e power cable must be laid as shown (Fig. 1-4).
In the event of mains fuse replacement on the
connection terminal board, use a 3.15A fast fuse.
For the main power supply to the appliance,
never use adapters, multiple sockets or extension leads.
Important: if the Digital Remote Control is
used, arrange two separate lines in compliance
with current regulations regarding electrical systems. No boiler pipes must ever be used to earth
the electric system or telephone lines. Ensure
elimination of this risk before making the boiler
electrical connections.
• Installation with system operating at direct
low temperature. The boiler can directly
supply a low temperature system, limiting the
value of the “P02” parameter, which denes the
generator’s ow temperature.
Attention: during the chimney sweep function,
the flow temperature is not limited by the
“P02” parameter but instead by the maximum
allowable temperature (97°C).
To avoid the risk of exceeding the optimal tem-
perature of operation in low temperature, due
to external causes (e.g.: incorrect adjustment,
prolonged system stop, etc.), you must insert
in series with the supply voltage of the boiler,
a special safety kit (optional) consisting of a
thermostat (with adjustable temperature, depending on the characteristics of the system).
The thermostat must be positioned on the
system ow pipe at a distance of more than 2
metres from the boiler.
Attention: in gure 4 is described the standard
electrical connection with the pump connected
to the terminals “Q” and “P”; in this way the
external pump is fed making it run in parallel
to the boiler pump. For specic installations
refer to paragraphs 3.18 to 3.21.

external probe.
ese components are available as separate kits
to the boiler and are supplied on request.
Carefully read the user and assembly instructions
contained in the accessory kit.
• e cascade and area regulator (Fig. 1-6) is
connected to the boiler using only two wires,
powered at 230 V and allows to:
- manage a hydraulic circuit with 2 mixed
zones (mixing valve); 1 direct zone; 1 Storage
tank unit and relative pumps;
- self-diagnosis system to display any boiler
functioning anomalies;
- set two room temperature value: one for
daytime (comfort temperature) and one for
nighttime (lower temperature);
- to manage the temperature of the DHW (with
a storage tank unit);
- to manage the boiler ow temperature de-
pending on the external temperature;
- to select the desired operating mode from
the various possible alternatives for each
individual hydraulic circuit:
- permanent operation in comfort temp.;
- permanent operation in lower temp.;
- permanent operation in adjustable anti-freeze
temp.
• Zone manager (Fig. 1-7). In addition to the
functions described in the previous point, the
zone manager panel allows to control all the
important information regarding operation
of the appliance and the heating system with
the opportunity of easily intervening on the
previously set parameters without having to
go to the place where the appliance is installed.
e climate chrono-thermostat incorporated
into the zone manager enables the system ow
temperature to be adjusted to the actual needs
of the room being heated, in order to obtain
the desired room temperature with extreme
precision and therefore with evident saving
in running costs. It also allows to display the
eective room temperature and the external
temperature (if external probe is present).
e zone manager is powered directly by the
cascade heat adjuster via 2 wires.

Thermostat or On/Off environment chronothermostat: must be connected to clamps “E” and
“F”. Make sure that the On/O thermostat contact
is of the “clean” type, i.e. independent of the mains
voltage, otherwise the P.C.B. would be damaged.
-
Cascade and zone regulator: must be connected through clamps 37 and 38 to clamps
“M” and “O” respecting polarity. e connec-
tion with incorrect polarity will not damage the
thermoregulator, but will not allow it to operate.
1.11 EXTERNAL TEMPERATURE PROBE.
e boiler is designed for the application of the
Room ermostat (Fig. 1-8), which is available
as an optional kit. Refer to the relative instruction
sheet for positioning of the external probe.
e probe can be connected directly to the boiler
electrical system and allows the max. system ow
temperature to be automatically decreased when
the external temperature increases, in order to
adjust the heat supplied to the system according
to the change in external temperature.
e electric connection of the external probe
must take place on clamps G and J on the connection in the boiler (Fig. 1-5).
By default, the external probe is not enabled. It is
necessary to set parameters “P14” and “P15” for
correct operation. e correlation between ow
temperature to the system and external temperature is determined by the curves represented
in the diagram (parameter “P14”) and by setting
the oset (parameter “P15”) (Fig. 1-9).
In case “P32” is bigger than “P15”, “P32” will be
the minimum limit for the set.
In case “P32” is lower than “P15”, “P32” will not
be considered.
N.B.: if the external probe is connected to the
cascade regulator, boiler parameter “P14” must
be set at “0”, and external probe control is delegated to the cascade regulator.

1.12 IMMERGAS FLUE SYSTEMS.
Hunt Heating can supply various solutions for
ueing and air supply.
Attention: the boiler must be installed exclusively with an original Immergas “Green
Range” inspectionable air intake system and
fumes extraction system made of plastic, with
the exception of the C6 conguration, as required by the regulations in force.
e plastic pipes cannot be installed outdoors,
for lengths longer than 40 cm, without suitable
INSTALLERUSER
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”.
• Conguration type B, open chamber and fan
assisted. e boiler leaves the factory with type
“B
” conguration.
23
Air intake takes place directly from the envi-
ronment in which the boiler is installed via
relevant slots made in the back of the boiler
and ue exhaust in the individual ue or to the
outside. Boiler with this type of conguration
are classied as type B
standard EN 297 and relative standards in
(in accordance with
23
force).
With this conguration:
- air intake takes place directly from the room
in which the appliance is installed;
- the ue exhaust must be connected to its own
individual ue or channelled directly into the
external atmosphere.
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours
or substances (e.g. acid vapours, glues, paints,
solvents, combustibles, etc.), as well as dusts
(e.g. dust deriving from the working of wood,
coal nes, cement, etc.), which may be harmful for the components of the appliance and
jeopardise operation.
• Type C conguration, sealed chamber and
fan assisted. e boiler leaves the factory with
"B
" conguration, to change the conguration
23
of the boiler to type "C" (sealed chamber and
fan assisted), disassemble the 80 Ø adapter, the
bracket and the gasket present on the boiler
cover and install the designated ue.
MAINTENANCE TECHNICIAN
N.B.: the 80 Ø adapter and gasket will be dis-
carded.
• Coupling extension pipes and concentric
elbows. To install push-tting extensions with
other elements of the ue, proceed as follows:
Install the concentric pipe or elbow with the
male side (smooth) on the female section
(with lip seal) to the end stop on the previously
installed element in order to ensure sealing
eciency of the coupling.
Attention: if the exhaust terminal and/or
concentric extension pipe needs shortening,
consider that the internal duct must always
protrude by 5 mm with respect to the external
duct.
• N.B.: for safety purposes, do not obstruct the
boiler intake-exhaust terminal, even temporaril y.
• N.B.: when installing horizontal pipes, a minimum inclination of 3% must be maintained
and a section clamp with pin must be installed
every 1.5 metres.
• Maximum extension. Each individual component has a resistance corresponding to a certain
length in metres of pipe with the same diameter
(par. 1.13). With installations that involve using
various types of parts, deduct the length of
the added part from the maximum admissible
length of the kit.
Example: if you need to add a 90° bend to
a concentric system 125 Ø you will need to
deduct 1.9 m from the maximum admissible
length.
• Positioning of the gaskets (black) for “green
range” ue extraction systems. Position the
gasket correctly (for bends and extensions)
(Fig. 1-10):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for exten-
sions;
N.B.: if component lubrication (already carried
out by the manufacturer) is not sucient, remove the residual lubricant using a dry cloth,
then to ease tting coat the parts with talc.

any number between 2 and 5 boilers, can be
manifolded to a unique ue exhaust pipe, which
ows into a ue.
Immergas supplied an appropriate and original
ue exhaust system separately to the boilers.
1.19 SYSTEM FILLING.
When the boiler has been connected, ll the system. Filling is performed at low speed to ensure
INSTALLERUSER
release of air bubbles in the water via the boiler
and heating system vents.
The boiler incorporates two automatic vent
valves tted on the circulator pump and on the
condensing module. Check if the cap is loose.
Open the radiator vent valves. Close radiator
vent valves when only water escapes from them.
N.B.: during these operations start up the circulation pump at intervals, acting on the main
switch positioned on the control panel. Vent the
circulation pump by loosening the front cap and
keeping the motor running. Tighten the cap aer
the operation.
Attention: this boiler is not equipped with an
expansion vessel on the system. It is mandatory
to install a closed expansion vessel to guarantee
correct boiler operation. e expansion vessel
must comply with the European and Australian standards in force. e dimensions of the
expansion vessel depend on the data relative
to the central heating system. Install a vessel
whose capacity responds to the requisites of the
Standards in force (''R'' collection).
1.22 BOILER START UP IGNITION.
To commission the boiler (the operations listed
below must only be performed by a qualied rm
and without any unauthorised persons):
- check that the internal system is properly sealed
according to the specications set forth by
regulations in force; Up to operating pressures
of 40 mbar it is also possible to use the testing
method adopted by the technical regulations
in force for systems served by single appliances
(or in cascade set-up), with nominal thermal
capacities greater than 35 kW. For greater pressure levels you will need to refer to legislation
in force and/or other eectively tried and tested
methods;
- 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 the fan rpm matches the value provided in the book (Par. 3.24);
- ensure that the safety device intervenes in the
event of gas supply failure and check the relative
intervention time;
- check activation 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.
Pre-fill the condense trap with water before
operating the boiler, to ensure products of combustion do not discharge from the trap itself.
1.21 GAS SYSTEM STARTUP.
To start up the system, refer to the technical
standard in force: is divides the systems and
therefore the start-up operations into three
categories: new systems, modified systems,
re-activated systems.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or open ames;
- bleed all air from the pipelines;
- check the seal of the internal system by following the instructions provided by the technical
MAINTENANCE TECHNICIAN
regulations in force (refer to the pertaining local regulations for the "sealing test" on systems
served by single or cascade generators with a
nominal thermal capacity greater than 35 kW.

1.23 CIRCULATION PUMP.
ese boilers are equipped with a variable speed
pump.
During CH mode, the pump speed is dened
according to parameters “P27” and “P28” and
it is adjusted in order to keep a constant DT of
18°C between ow and return.
During DHW mode, the pump always runs at
the maximum speed.

e boiler will let you know of any anomalies by
the ashing screen and code. ere are dierent
types of codes that can be divided up as follows:
- “0Axx” for resettable anomalies (Fig. 2-9).
(Before resetting the anomaly you will need to
wait for the boiler to nish its post-ventilation
function, which lasts approximately 60 seconds).
- “0Exx” and “FExx” for non-resettable anomalies.

2.8 BOILER SHUTDOWN.
Disconnect the main switch (1) taking it to the
“0” position and close the gas cock upstream
from the appliance.
Never leave the boiler switched on if le unused
for prolonged periods.
2.9 RESTORING CENTRAL HEATING SYSTEM PRESSURE.
Periodically check the system water pressure.
e boiler manometer should indicate a value
not below 0.5 bar.
If the pressure is below 0.5 bar (with cold system)
the water inside the system must be restored.
N.B.: close the valve aer the operation.
If pressure values reach around 4 bar the safety
valve may be activated.
In this case, remove water from an air vent valve
of a radiator until reaching pressure of 1 bar, or
ask for assistance from professionally qualied
personnel.
In the event of frequent pressure drops, contact
qualified staff for assistance to eliminate the
possible system leakage.
2.10 SYSTEM DRAINAGE.
To drain the boiler, use the appropriate system
drain tting.
Before draining, ensure that the system lling
valve is closed.
2.11 ANTIFREEZE PROTECTION.
e boiler is supplied with an antifreeze function
as standard that activates the function of the
pump and the burner when the system water
temperature in the boiler falls below 5°C. e
antifreeze function is guaranteed if the boiler is
fully operative, if it is not in "block" status and
is electrically powered with the main switch on
"ON". To avoid keeping the system switched on
in case of a prolonged absence, the system must
be drained completely or antifreeze substances
must be added to the heating system water. 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 professional sta for the procedures and
ensure that the electrical, water and gas supply
lines are shut o and disconnected.

3.7 TROUBLESHOOTING. N.B.: maintenance interventions must be carried
out by a qualied licensed operative.
- 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 valve is open. Incorrect
adjustment of the gas valve, 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 CO
gases.
- e over temperature safety thermostat, the
ow probe or the return probe are triggered
frequently. 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.
In addition:
- Also check the integrity of the thermofuse, and
if it has been triggered it will be necessary to
check the integrity of the module and the ue
circuit.
- Check that the exchanger safety thermostat has
not intervened. If it has, check the integrity of
the module and ceramic bre panel, replace
the cover gasket of the manifold and reset the
thermostat by pressing the specic button.
- Heat exchanger clogged. is may be caused by
the trap being blocked. Check, by means of the
condensate drain cap, that there are no residues
of material blocking the ow of condensate.

- Noise due to air in the system. Check opening
of the special air vent valve cap (Fig. 1-25 Ref.
19). Check that system lling and air bleeding
has been performed according to the requirements.
- Noise due to air inside the condensation
module. Use the manual air vent valve (Fig.
1-25 Ref. 15) to eliminate any air present in the
condensation module. When the operation has
been performed, close the manual vent valve.
- No DHW is produced. e boiler is equipped
with a function that automatically recognises
when there is an optional DHW probe, and an
anomaly is reported if there is a failure aecting
the DHW NTC probe. If there is a power outage, or if the boiler is switched o and back on
again during the failure, it will not be possible
to detect said failure, but it will, however, be
recorded in the errors anomaly records.
- In case of ΔT > 35 °C, the boiler lowers the
power to avoid surpassing that value. When
this status is on, the ow temperature symbol
ashes.

3.9 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.
Boiler conversion must be carried out by a qualied Licensed operative.
To convert to another type of gas the following
operations are required:
- disconnect the appliance;
- Change the sleeve with Venturi (det. 5 Fig.
INSTALLERUSER
1-25);
- change the gas nozzle (det. 4 Fig. 1-25);
- re-power the appliance;
- regulate the maximum heat output by varying
the number of fan revs. (parameter P25 “Max
number of fan revs in CH mode”) according to
par. 3.24;
- regulate the minimum heat output by varying
the number of fan revs. (parameter P26 “Min
number of fan revs in CH mode”) according to
par. 3.24;
- activate the chimney sweep function;
- check the CO
especially:
- che ck the CO
sweep at 0%;
- che ck the CO
sweep at 100%;

- exit the chimney sweep function;
- seal the gas ow rate regulation devices (if
settings are modied);
- after completing the conversion, apply the
sticker, contained in the conversion kit, near
the data-plate. Using an indelible marker pen,
cancel the data relative to the old type of gas.
ese adjustments must be made with reference
to the type of gas used.
3.10 CHECKS FOLLOWING CONVERSION TO ANOTHER TYPE OF GAS.
After making sure that transformation was
carried out with the Venturi and a nozzle of
suitable diameter for the type of gas used and
the calibration has been performed at the correct
num. of revs, check that:
- the burner ame is not too high and that it is
stable (does not detach from burner);
MAINTENANCE TECHNICIAN
- there are no leaks from the gas circuit.
N.B.: all boiler adjustment operations must be
carried out by a qualied licensed operative.
3.11 ADJUSTMENT OF THE AIRGAS
RAT IO.
Calibration of minimum CO
Turn the boiler on and start the chimney sweep
2
functions at minimum output (0%). To have an
exact value of CO2 the technician must insert a
ue gas analyzer sampling probe le hand sample point, then check that the CO
specied in the table in par. 3.24, if adjustment
value is that
2
is required, turn screw (3 Fig. 3-12) (O-Set
regulator). To increase the CO
adjustment screw (3) in a clockwise direction and
value, turn the
2
vice versa to decrease it.
Calibration of maximum CO
When you nish the minimum CO2 adjustment,
.
2
turn the boiler on and start the chimney sweep
function at the maximum output (100%). To have
an exact value of CO2 the technician must insert
a ue gas analyzer sampling probe le hand sample point, then check that the CO2 value is that
specied in the table in par. 3.24, if adjustment
is required, turn screw (12 Fig. 3-12) (gas ow
rate regulator).
To increase the CO2 value, turn the adjustment
screw (12) in an anti-clockwise direction and vice
versa 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.).
3.12 CH OUTPUT ADJUSTMENT.
If it is necessary to change the CH output, you
will need to adjust the “P08” maximum CH output and “P09” minimum CH output parameters.
To check the regulated heat output value, compare the no. of fan revs with that in the table
(par. 3.24).
3.13 OUTPUT ADJUSTMENT DURING
DHW ONLY IN COMBINATION
WITH AN OPTIONAL EXTERNAL
STORAGE TANK.
If it is necessary to change the DHW output,
you will need to adjust the “P20” maximum
DHW output and “P21” minimum DHW output
parameters.
To check the regulated heat output value, compare the no. of fan revs with that in the table
(par. 3.24).
3.14 “CHIMNEY SWEEP” FUNCTION.
is function allows the technician to check
the combustion parameters. Boiler operation in
chimney sweep function can be adjusted to an
output between 0% and 100%.
To enable the function press and hold down “A”
3-11
If there is a common ow probe, it is possible to
activate the chimney sweep function by pressing buttons “A” and “B” simultaneously. In this
case, the plant pump is activated as well as the
boiler (in the “simple cascade” both boilers are
activated) e output is adjusted from the + and
- DHW adjustment buttons at a range between
0 and 100%, while using the + and - buttons for
CH adjustment, the percentage changes by 1%
each time they are pressed.
In this state all adjustments are excluded and
only the temperature safety thermostat and the
limit thermostat remain active. When the checks
are nished disable the function by pressing and
holding down button “A”.
If you enable the function, you will need to wait
approximately 30’’ to reach the set output (3’ on
the Slave boiler)

3.15 3WAY PUMP ANTIBLOCK
FUNCTION OPTIONAL.
e boiler has a function that starts the pump
and 3-way valve at least once every 24 hours for
the duration of 20 seconds in order to reduce
the risk of the pump becoming blocked due to
prolonged inactivity.
3.16 RADIATORS ANTIFREEZE
FUNCTION.
e boiler has a function that makes the pump
start when the system ow water reaches 8 °C. If
the system ow water is at a temperature below
5 °C, the boiler starts to operate until it reaches
approximately 16 °C.
3.17 ANTIHUMIDITY ELECTRODE
FUNCTION.
With cascade installations combined with their
relative ue manifold kits with ue adjusting
devices, humidity may develop on the electrodes,
causing them to fail. Avoid the formation of
humidity by enabling this function (by setting
a value other than 0), which turns the fan on
at the speed set in parameter “P11” (5 minutes
on and 5 minutes o). e function is active
when the burner is o and the ow NTC probe
temperature reading is greater than 35°C. e
function is disabled when the temperature drops
below 30 °C.
3.18 INLET 0 ÷ 10 V.
e microprocessor has an analogue 0 ÷ 10 V
inlet (“Y” and “Z” terminals Fig. 1-4) that enables
the boiler to be controlled from the outside.
By setting the “P37” parameter, it is possible
to set-up the inlet by choosing the functioning
mode between temperature set and power set.
e inlet activates a 2 V (minimum) request and
increases it proportionally up to 9.5 V (maximum). e request is deactivated below 1 V.
Notes:
- If “P37” is set at “0”, it is not active when the
boiler is in “stand-by” or “summer” mode.
e calculated set is dened within the “P02”
÷ 20 °C range. e maximum and minimum
temperature within the set is limited by “P01”
and “P32”.
- If “P37” is set on “1” it is always active. It is not
limited by the “P08” and “P09” parameters
and does not have priority over the DHW
request.
- Input voltage = -2.5 ÷ 12.5 V
- Input = 200 μA
- Impedance = > 50 KΩ
3.19 FUNCTIONING WITH COMMON FLOW PROBE.
With a hydraulic circuit breaker, there must be
a common ow probe (with boiler ow probe
functions) and a pump to be connected downstream of the plant.
e probe must be connected to terminals “S1”
and “S2” and parameter “P38” must be set up,
whereas the pump must be connected to terminals “C” and “D”.
If there is a DHW circuit, it can be connected
via an external 3-way to be connected to “IT”,
“IS” and IK terminal, or use a suitable pump to
be connected to “IT” and “IK” terminals. e
DHW circuit has priority over the heating circuit.
Please refer to chart Fig. 3-13 for the correct
conguration.
3.20 AUTODETECTION.
This function enables the association of the
display board to the boiler’s P.C.B. In addition,
in case of “simple cascade” installation, it enables
the detection and combination of cascade boilers.
Turn the boiler on, programme it according to
your needs, press and hold the “-” (Fig. 2-1 ref.
2) button down until “AUTO” appears, then press
“RESET” until “bu 1” appears.
3.21
SIMPLE CASCADE MAX. 2 BOILERS
It is possible to create a “simple cascade” by
directly connecting two boilers.
e two boilers turn on alternatively based on
the plant’s requirements.
Carry out the connection as indicated in the
diagram (Fig. 3-6). With this configuration,
there must be a common flow probe on the
thermal plant, see the chart (Fig. 3-13) for the
possible options.
In order for the system to recognise the two
boilers, you must activate the Autodetection and
make sure both boilers are on.
ey are associated when “bu 2” appears on
the Master boiler and “SLA 2” appears on the
Slave boiler.
From this moment on, all programming is carried out on the Master boiler, while the “SLA 2”
caption always appears on the Slave boiler, except
in case of anomaly.
e customised parameters of the Master boiler
are automatically replicated on the Slave boiler.
Warning: it is not possible to combine the cascade
and zone regulator to the plant in this case. It is
possible to connect an On/O room thermostat
or use the 0 ÷ 10 V inlet (which must only be
connected to the Master) to control the plant.

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
drainage 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 the system static pressure (with
system cold and aer relling the system by
means of the ller cock) is not below 0.5 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 elec-
trical system and in particular:
- electrical power cables must be inside the
fairleads;
- there must be no traces of blackening or
