BOILER INSTALLATION.
1.1 INSTALLATION
RECOMMENDATIONS.
e Victrix Tera boiler has been designed for
wall mounted installation only; for central heating and production of domestic hot water for
domestic use and similar purposes.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural), such as to allow for (always in safe, ecient and comfortable
conditions):
- installation (according to the provisions of
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine, special);
- removal (to outdoors in the place for loading
and transporting the appliances and components) as well as the eventual replacement
of those 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).
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
the sealed chamber boiler for intake of air 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.
Important: 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
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, if the drain trap is blocked, or
if there are leaks from the hydraulic connections; otherwise, 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 immediately
and contact an authorised company (e.g. the
Immergas 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 Standards:
- this boiler can be installed outdoors in a
partially protected area. A partially protected
area is one in which the boiler 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 of gas appliances, ue exhaust
pipes and combustion air intake pipes is
forbidden in places with a re risk (for example: garages, closed parking stalls), and
in potentially dangerous places.
- Installation is prohibited on the vertical
projection of the cooking surface.
- Installation is forbidden in places/rooms
that constitute public areas of apartment
buildings, internal stairways or other escape
routes (e.g. oor landings, entrance halls,
etc.).
- Installation is also forbidden in places/rooms
that constitute public areas of apartment
buildings such as cellars, entrance halls, attics,
los, etc., unless otherwise provided for by
local regulations in force.
Attention: installing the wall recessed frame
kit must guarantee the boiler stable, ecient
support. e recessed frame kit ensures appropriate support only if installed correctly
(according to the rules of good practice),
following the instructions on its instructions
leaet. e recessed frame for the boiler is not
a supporting structure and must not replace
the wall removed. It is necessary to position
the boiler inside the wall. For safety reasons
against any leaks it is necessary to plaster the
boiler housing in the brick wall.
Attention: wall mounting of the boiler must
guarantee stable and ecient support for the
generator.
e plugs (standard supply) are only to be used
to x the boiler 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 mount.
ese boilers are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a central heating
system and domestic hot water circuit suited to
their performance and capacity.

1.3 ANTIFREEZE PROTECTION.
Minimum temperature -5°C. e boiler comes
standard with an antifreeze 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 -5°C.
Minimum temperature -15°C. If the boiler is
installed in a place where the temperature drops
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
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 (antifreeze kit) comprising two
electric heating elements, the relevant wiring
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 -5°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 “o” mode.
- the boiler is not in anomaly conditions (Parag.
2.5);
- 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.
N.B.: 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.

1.4 INSTALLATION INSIDE A
RECESSED FRAME OPTIONAL.
e boiler is designed for installation inside the
Immergas recessed frame (supplied as optional).
e necessary parts for this type of installation
(brackets) must also be purchased separately as
optional kit.
To install proceed as follows:
- Install the bracket (2) inside the recessed frame
xing it with the screws (3) in the pre-drilled
holes (Fig. 3).
- Hang the boiler (4) to the bracket (2) (Fig. 4).
- Block the boiler (4) by mounting the brackets
(5) and xing them with their screws (6) (Fig.
5).
e brackets (5) used to centre the boiler on
the frame and hold it in place stop against the
frame (1) so do not require xing to the frame
itself.

1.5 BOILER CONNECTION UNIT.
e connection unit consisting of all the necessary parts to perform the hydraulic and gas
system connections of the appliance comes as
optional kit, perform the connections respecting
the arrangement of Fig. 6 based on the type of
installation to be made.
1.6 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 3/4”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
nameplate). If dierent, the boiler must be converted for operation with the other type of gas
(see converting appliance for other gas types). It
is also important to check the dynamic pressure
of the mains (methane or LPG) used to supply the
boiler, which must comply with EN 437 and its
attachment, as insucient levels may reduce generator output and cause discomfort to the user.
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
standards in force.
Fuel gas quality. e appliance was designed to
operate with combustible gas free of impurities;
otherwise it is advisable to fit special filters
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.
1.7 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 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. In
order not to void the heat exchanger warranty,
you are required to comply with what has been
prescribed in Paragraph 1.23.
Water connections must be made in a rational
way using the couplings on the boiler template.
Attention: Immergas declines all liability in the
event of damage caused by the installation of an
automatic lling system.
In order to meet the system requirements established by EN 1717 in terms of pollution of
drinking water, we recommend installing the
IMMERGAS anti-backow 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 (C.H. circuit), as dened
in standard EN 1717.
Attention: to preserve the duration and the eciency 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.
3 bar safety valve. Discharge of the safety valve
has been conveyed to the condensate drain trap
outlet. Consequently, in the event of valve intervention, the discharged liquid will end up in
the sewer system through the drain pipe of the
condensate drain trap.
In any case the lower part of the appliance is
tted with a drain tting (Ref. 3 Fig. 6) with the
relative closure cap to check for the presence of
liquid in the discharge circuit and to check the
intervention of the 3 bar safety valve.
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 occlusion and 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. 1.25). 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.

1.8 ELECTRICAL CONNECTION:
e appliance has an IPX5D protection degree;
electrical safety of the appliance is achieved 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.
• Open the control panel connections compartment (Fig. 7).
To carry out electrical connections, all you have
to do is open the connections compartment as
follows (Fig. 7):
- Disassemble the cover (Fig. 53).
- Disassemble the cover (b)
1) Loosen the screw (a).
2) Press the two hooks on the connections
compartment cover.
3) Remove the cover (b) from the control
panel (c).
- At this point, it is possible to access the terminal
board (d).
Also ensure that the electrical installation corresponds to maximum absorbed power specications as shown on the boiler data nameplate.
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, it is necessary to provide a type A dierential
safety device.
When replacing the power supply cable, contact a
qualied company (e.g. the Immergas Authorised
Aer-Sales Technical Assistance Service). e
power cable must be laid as shown (Fig. 6).
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.
Installation with system operating at direct
low temperature. e boiler can directly supply
a low-temperature system by setting the ow
temperature adjustment range “t0” and “t1” (Par.
3.8). In this situation it is good practice to insert
a relevant safety kit (optional) made up from a
thermostat (with adjustable temperature). e
thermostat must be positioned on the system
ow pipe at a distance of at least 2 metres from
the boiler.
1.9 REMOTE CONTROLS AND
ROOM CHRONOTHERMOSTATS
OPTIONAL.
e boiler is prepared for the application of room
chrono-thermostats or remote controls, which
are available as optional kits (Fig. 8).
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the accessory kit.
• On/O Immergas digital chrono-thermostat.
e chrono-thermostat allows:
- set two room temperature value: one for day
(comfort temperature) and one for night
(reduced temperature);
- set a weekly programme with four daily
switch on and switch o times;
- selecting the required function mode from
the various possible alternatives:
• manual operation (with adjustable tempera-
ture).
• automatic operation (with set programme).
• forced automatic operation (momentarily
changing the temperature of the automatic
programme).
e chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control De-
vice V2 (CARV2) with climate chrono-thermostat
function. In addition to the functions described
in the previous point, the CARV2 panel enables
the user to control all the important information regarding operation of the appliance and
the heating system with the opportunity to
easily intervene on the previously set parameters, without having to go to where the appliance is installed. e panel is provided with
self-diagnosis to display any boiler functioning
anomalies. The climate chrono-thermostat
incorporated into the remote panel 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. e CARV2 is
fed directly by the boiler by means of the same 2
wires used for the transmission of data between
the boiler and device.
Comando Amico Remoto Remote Control V2
or On/O chrono-thermostat electrical connections (Optional). e operations described
below must be performed aer having removed
the voltage from the appliance. Any thermostat
or On/O environment chrono-thermostat must
be connected to clamps 44/40 and 41 eliminating
jumper X40 (Fig. 38). 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. Any Comando Amico
Remoto Remote Control V2 must be connected
to clamps 44/40 and 41 eliminating jumper X40
on the P.C:B., paying attention not to invert the
polarity in the connections (Fig. 38). e boiler
can only be connected to one remote control.
Important: if the Comando Amico Remoto Remote Control V2 or any other On/Off
chrono-thermostat 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.

EXTERNAL PROBE
Correction law of the ow temperature depending on the external temperature
and user adjustments of the central heating temperature.
1.10 EXTERNAL TEMPERATURE PROBE
OPTIONAL.
e boiler is designed for the application of the
external temperature probe (Fig. 9), 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 external probe always operates when connected,
regardless of the presence or type of room
chrono-thermostat used and can work in combination with Immergas chrono-thermostats. e
correlation between system ow temperature
and external temperature is determined by the
position of the central heating selector switch on
the boiler control panel (or on the CARV2 control
panel if connected to the boiler) according to
the curves shown in the diagram (Fig. 10). e
electric connection of the external probe must be
made on clamps 38 and 39 on the terminal board
in the boiler control panel (Fig. 38).

1.11 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 system and
flue gas 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 tracts longer than 40 cm, without suitable
protection from UV rays and other atmospheric agents.
is ue can be identied by an identication
mark and special distinctive marking bearing
the note "only for condensation 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 of the gaskets (black) for “green
range” ue extraction systems. Position the
gasket correctly (for bends and extensions)
(Fig. 11):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for exten-
sions;
N.B.: if necessary, to ease the push-fitting,
spread the elements with commonly-used talc.
• 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

1.13 OUTDOOR INSTALLATION IN
PARTIALLY PROTECTED AREA.
N.B.: a partially protected location is one in which
the appliance is not exposed to the direct action of
the weather (rain, snow, hail, etc..)..
• Conguration type B, open chamber and fan
assisted.
Using the special coverage kit one can achieve
direct air intake (Fig. 12) and ue gas exhaust
in a single chimney 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
(external);
- the ue gas 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. 13). Remove the
two plugs from the lateral intake holes. Now
cover the le intake hole using the relevant
plate, xing it onto the right 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 metal sheet
plate and tighten by means of the clips present
in the kit, making sure to block the 4 gasket
aps. Fit the male end (smooth) of the exhaust
terminal into the female end of the bend 90° Ø
80, making sure that the relevant wall sealing
plate 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: Install the pipe
or elbow with the male side (smooth) in the
female section (with lip seal) to the 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)
N.B.: a partially protected location is one in
which the appliance is not exposed to the direct
action of the weather (rain, snow, hail, etc..)..
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 and Ø 80/125 concentric intake/
exhaust kits. Refer to the paragraph on indoor
installation. In this conguration the upper
cover kit guarantees additional protection for
the boiler. It is recommended but not compulsory. e Ø 80/80 separating device cannot be

assisted.
Using a kit separator one can achieve direct air
intake (Fig. 16) and ue gas exhaust in a single
chimney or directly outside. In this conguration
the boiler is classied as type B23.
With this conguration:
- air intake takes place directly from the envi-
ronment in which the appliance is installed
(the recessed frame is ventilated), and only
functions in permanently ventilated rooms;
- the ue gas exhaust must be connected to its
own individual ue or channelled directly into
the external atmosphere.
The technical regulations in force must be
respected.
Separator kit installation: install the discharge
ange on the central hole of the boiler, positioning the relative gasket 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 lateral hole with respect to
the central one (according to needs) and replace
it with the intake ange, positioning its gasket
already present in the boiler and tighten using
the supplied self-threading screws. Fit the male
side (smooth) to the bends in the female side of
the anges.
e intake bend must face the rear side of the
boiler.
Fit the exhaust pipe with the male side (smooth)
to the female side of the bend up to the end stop,
making sure that the internal wall sealing plate
has been tted and connecting the required ue

1.18 ADAPTOR C9 KIT INSTALLATION.
is kit allows an Immergas boiler to be installed
in "C93" conguration, with combustion air intake
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;
- rigid ducting Ø 60 and Ø 80 and exible Ø 50
and Ø 80 kit;
- ue 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. 29).
- (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
up to the end stop in the ducting system curve
(Quota "X" Fig. 30), whereas the external pipe
must reach the end stop of the adapter (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. 30).
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. 28).
- 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
93
ue system in congurations other than that described (Fig. 30)
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 C
93
ue system in congurations other than that described (Fig. 30) 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.

1.19 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. 31). 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, Ø
80 exible and Ø80 rigid “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; in particular, the
declaration of conformity must be compiled at
the end of work and on commissioning of the
ducted system. 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 envi-
ronmental conditions, according to current

1.20 CONFIGURATION TYPE B, OPEN
CHAMBER AND FAN ASSISTED FOR
INDOORS.
e appliance can be installed inside buildings
in 23 or B53 mode; in this case, all technical rules
and national and local regulations in force, must
be complied with.
- 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 damaging for
the components of the appliance and jeopardise
functioning.
- in B23 and B53 conguration, unless otherwise
provided for by local regulations, the boilers
must not be installed in bedrooms, bathrooms
or in studio ats. ey must neither be installed
in rooms containing solid fuel heat generators
nor in rooms communicating with said rooms.
- Installation of appliances in B23 and B53 conguration is recommended in non-residential
premises and which are permanently ventilated.
For installation the cover kit must be used, referred to in Paragraph 1.13.
1.21 FLUE EXHAUST TO FLUE/CHIMNEY.
Flue exhaust does not necessarily have to be connected to a branched type traditional ue. e ue
exhaust, for boiler clots installed in C conguration,
can be connected to a special LAS type multiple ue.
For B23 congurations, exhaust is only allowed into
individual chimney or directly into the external
atmosphere via a relevant terminal. e multiple
ues and the combined ues must also only be
connected to type C appliances of the same type
(condensation), having nominal heat inputs that do
not dier by more than 30% less with respect to the
maximum that can be attached and powered by the
same fuel. e thermo-uid dynamic features (ue
ow rate, % of carbon dioxide, % humidity etc....) of
the appliances attached to the same multiple ues
or combined ues, must not dier by more than
10% with respect to the average boiler attached.
Multiple and combined ues must be specially
designed according to the calculation method and
requirements of the technical standards in force,
by a professionally qualied company. Chimney
or ue sections for connection of the ue exhaust
pipe must comply with requisites of technical
standards in force.

INSTALLERUSERMAINTENANCE TECHNICIAN
1.22 FLUES, CHIMNEYS AND CHIMNEY
CAPS.
e ues, chimneys and chimney caps for the
evacuation of combustion products must be in
compliance with applicable standards. Chimneys
and roof-installed exhaust terminals must comply with the outlet height and with the distance
from technical volumes set forth by the technical
standards in force.
Positioning the wall ue exhaust terminals. e
wall ue exhaust terminals must:
- be installed on external perimeter walls of the
building;
- be positioned according to the minimum dis-
tances specied in current technical standards.
Combustion products exhaust of natural
draught or fan assisted appliances in open-top
closed environments. In spaces closed on all
sides with open tops (ventilation pits, courtyards etc.), direct combustion product exhaust
is allowed for natural draught or fan assisted gas
appliances with a heat input range from 4 to 35
kW, provided the conditions as per the current
technical standards are respected.
1.23 WATER TREATMENT SYSTEM
FILLING.
As already mentioned in the previous paragraphs, a treatment of the thermal and domestic
system water is required, in compliance with the
local standards in force.
e parameters that inuence the duration and
proper operation of the heat exchanger are the
water's PH, hardness, conductivity, and oxygen,
together with the system's processing residues
(any welding residues), any oil present and corrosion products that can, in turn, cause damage
to the heat exchanger.
In order to prevent this from happening, you are
recommended to:
- Before installation on new systems as well as
old ones, clean the system with clean water to
eliminate solid residues contained therein.
- Clean the system with a chemical treatment:
- Clean the new system with a suitable cleaning
device (for example Sentinel X300, Fernox
Cleaner F3 or Jenaqua 300) combined with
thorough washing.
- Clean the old system with a suitable cleaning
device (for example Sentinel X400 or X800,
Fernox Cleaner F3 or Jenaqua 400) combined
with thorough washing.
- Check the maximum hardness and quantity
of lling water referring to the graphics (Fig.
32). If the contents and hardness of the water
are below the indicated curve, no specific
treatment is required; otherwise, to limit the
content of calcium carbonate, you must provide
for water-lling treatment.
- For lling, you are not allowed to use water
soened with the use of ionic-exchange resins
or distilled water.
- Should you be required to provide for water
treatment, this should be carried out by
completely desalinating the lling water. As
opposed to the complete soening process,
desalinating the water completely not only
removes hardening agents (Ca, Mg), but also
eliminates all other minerals to reduce water-lling conductivity up to 10 microsiemens/
cm. Given its low conductivity, desalinated
water does not only prevent the formation of
lime scale, but also serves as protection against
corrosion.
- Insert a suitable inhibitor / passivator (for
example Sentinel X100, Fernox Protector F1,
or Jenaqua 100); if required, also insert appropriate antifreeze (such as for example Sentinel
X500, Fernox Alphi 11 or Jenaqua 500).
- Check electrical conduction of the water, which
should be higher than 2000 µs/cm in the case
of treated water and lower than 600 µs/cm in
the case of non-treated water.
- To prevent corrosion, the water system's PH
should be between 7.5 and 9.5.
- Check the maximum content of chlorides,
which should be less than 250 mg/l.
N.B.: for quantities and methods of use of water-treatment products, refer to the instructions
provided by their manufacturer.
1.24 SYSTEM FILLING.
Once the boiler is connected, proceed with
system lling via the lling cock (Part. 26 Fig.
35). Filling is performed at low speed to ensure
release of air bubbles in the water via the boiler
and central heating system vents.
e boiler has a built-in automatic venting valve on
the pump. Check if the cap is loose. Open the radiator
vent valves.
Close radiator vent valves when only water
escapes from them.
Close the lling valve when the boiler pressure
gauge indicates approx. 1.2 bar.
N.B.: during these operations, enable the automatic vent functions on the boiler (active on
rst ignition).
1.25 FILLING THE CONDENSATE DRAIN
TRAP.
On rst lighting of the boiler, ue gas may come
out the condensate drain; aer a few minutes’
operation check that this no longer occurs. is
means that the drain trap is lled with condensate to the correct level preventing the passage
of ue gas.
Water hardness °F
System water litres
N.B.: the graph refers to the
entire life cycle of the system.
erefore, also consider scheduled and unscheduled maintenance, which involves emptying
and lling the said system.

1.28 CIRCULATION PUMP.
e boilers are supplied with a variable speed
circulator pump.
In the central heating mode, the following operating modes are available and can be selected
from the “P.C.B. programming” menu.
N.B.: the ∆T(A3) can be controlled compatibly
with the characteristics of the central heating
system and of the boiler.
• Proportional head (A3 = 0): the circulator
speed varies according to the power emitted
by the burner, the greater the power the greater
the speed.
• ∆T Constant (A3 = 5 ÷ 25 K): the pump speed
varies to maintain the ∆T constant between the
system ow and return according to set value
K (A3 = 15 Default).
• Fixed: by setting parameters “A1” and “A2” at
the same value (5/6 ÷ 9), the pump operates at
constant speed. For the boiler to work properly,
it is not allowed to drop below the minimum
value set out above.
In domestic hot water mode, the circulator pump
always runs at full speed.
Pump release. If, aer a prolonged period of
inactivity, the circulation pump is blocked, turn
the motor sha using a screwdriver. Take great
care during this operation to avoid damage to
the motor.
By-pass Regulation (Part. 23 Fig.35). e boiler
leaves the factory with the bypass open.
If necessary, the by-pass can be regulated to
system requirements from minimum (by-pass
closed) to maximum (by-pass open). Adjust
using a at-head screwdriver. Turning clockwise
opens the bypass and anticlockwise closes it.
1.26 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 naked ames;
- bleed all air from pipelines;
- ensure the internal system is properly sealed
according to the specications set forth by
technical regulations in force.
1.27 BOILER STARTUP IGNITION.
To commission the boiler (the operations listed
below must only be performed by qualied personnel and in the presence of sta only):
- check that the internal system is properly sealed
according to the regulations in force;
- ensure that the type of gas used corresponds to
the boiler settings (the type of gas appears on the
display on rst electrical supply voltage, or by
checking the relative parameter “G”);
- check connection to a 230V-50Hz power mains,
correct L-N polarity and earthing connection;
- Check that there are external factors that may
cause the formation of fuel pockets;
- switch the boiler on and ensure correct ignition;
- make sure that the gas ow rate and relevant
pressure values comply with those given in the
manual (Par. 3.21);
- ensure that the safety device is engaged in the
event of gas supply failure and check activation
time;
- check the intervention of the main switch
located upstream from the boiler and in the
boiler;
- check that the intake and/or exhaust terminals
(if tted) are not blocked.
- Carry out the ue test.
e boiler must not be started up even if only
one of the checks should be negative.

2.4 USING THE BOILER.
Before ignition make sure the heating system
is lled with water and that the manometer (8)
indicates a pressure of 1 ÷ 1.2 bar.
- Open the gas cock upstream from the boiler.
- Press the button “ “ repeatedly to
cyclically switch from “stand-by” ( ) to
“summer” ( ) and “winter” ( ) mode.
• Summer ( ): in this mode the boiler functions only to produce the DHW, the temper-
ature is set via the buttons “ “ and the
relative temperature is shown on the display
via the indicator (19). Moreover, the temperature level that can be selected is shown on the
indicator (22).
• Winter ( ): in this mode the boiler works
both for producing domestic hot water and
for central heating. e DHW temperature is
always regulated via the buttons “ “, the
central heating temperature is regulated via the
buttons “ “ and the relative temperature
is shown on the display via the indicator (19).
Moreover, the temperature level that can be
selected is shown on the indicator (15).
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.
Each time the burner ignites, the relative ame
present symbol is displayed (11) with relative
output scale.
• Operation with Comando Amico Remoto
remote control V2 (CARV2) (Optional). If the
CARV2 is connected, the ( ) symbol will
appear on the display. e boiler regulation parameters can be set via the CARV2 control panel
and the reset button (3) remains active on the
boiler control panel, along with the switch-o
button (1) (“o” mode only) and the display
where the functioning state is shown.
Caution: if the boiler is switched “o ” the
CARV2 will display the connection error symbol
“ERR>CM”, the CARV2 is however powered
constantly so as not to lose the stored programs.
• Solar operating mode ( ). is function
is activated automatically id the boiler detects
a probe on the DHW inlet (optional) or if the
“Solar ignition delay” parameter is more than
0 seconds.
During a withdrawal, if the outlet water is hot
enough or if there is “Solar ignition delay” time,
the boiler does not switch on, the D.H.W. with-
drawal symbol ( ) appears on the display
along with the ashing solar function symbol
( ).
When the water supplied by the solar system
is at a temperature lower than what is set, or
if the “Solar ignition delay” time has elapsed,
the boiler switches on. At this point, the solar
function symbol remains permanently on.
• Operation with optional external probe
( ). In the case of a system with optional
external probe, the boiler ow temperature
for room central heating is managed by the
external probe depending on the external
temperature measured (Par. 1.10). e ow
temperature can be modied by selecting the
functioning curve via the buttons “ “ (or
on the CARV2 control panel, if connected to the
boiler) selecting a value from “0 to 9”.
With external probe present, the relative
symbol (12) will appear on the display. In the
central heating mode, if the temperature of the
water contained in the system is sucient to
heat the radiators, the boiler can only function
with the activation of the pump.
• “Stand-by” mode. Press button “ “ re-
peatedly until the symbol ( ) appears. From
now on the boiler remains inactive and the
antifreeze function, pump anti-block function
and 3-way and signalling of any anomalies is
guaranteed.

between 1 and 1.2 bar.
If pressure falls below 1 bar (with the circuit cold),
restore normal pressure via the cock located at the
bottom of the boiler (Part. 1 Fig. 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 a radiator air
vent valve until a pressure of 1 bar is achieved,
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.
2.9 DRAINING THE SYSTEM.
To drain the boiler, use the special draining
valve (Fig. 6).
Before draining, ensure that the lling cock is
closed.
2.10 ANTIFREEZE PROTECTION.
The “Victrix Tera” series boiler features an
antifreeze function that lights the burner automatically when the temperature falls below
4°C (standard protection down to min. temperature of -5°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:
- the electric power supply is disconnected;
- the heating circuit and boiler domestic 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.
2.11 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the boiler casing. Never use abrasive or powder
detergents.
2.12 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.

3.3 TROUBLESHOOTING
N.B.: maintenance interventions must be carried
out by an authorised company (e.g. Immergas
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. It can be caused by
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 safety thermostat
function (delegated to ow probe and system
return probe). It can depend on the lack of
water in the boiler, little water circulation in the
system or blocked pump. Check on the pressure
gauge that the system pressure is within established limits. Check that the radiator valves
are not closed and also the functionality of the
pump.
- Siphon blocked. is may be caused by dirt or
combustion products deposited inside. Check,
by means of the condensate drain cap, that
there are no residues of material blocking the
ow of condensate.
- Heat exchanger blocked. is may be caused
by the drain 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. 6). 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.
3.4 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 nameplate,
request the relative conversion kit for quick and
easy conversion.
e gas conversion operation must be carried
out by an authorised company (e.g. Immergas
Aer-Sales Technical Assistance Service).
To convert to another type of gas the following
operations are required:
- remove the voltage from the appliance;
- replace the nozzle located on the gas valve and
gas/air mixing sleeve (Part. 9 Fig. 35), taking
care to disconnect the appliance during this
operation;
- apply voltage to the appliance;
- calibrate the number of fan revolutions (Parag.
3.5);
- adjust the correct air/gas ratio (Parag. 3.6);
- seal the gas ow rate devices (if adjusted);
- after completing the conversion, apply the
sticker, contained in the conversion kit, on the
data plate in the area relating to the type of gas.
ese adjustments must be made with reference
to the type of gas used, following that given in
the table (Par. 3.21).
3.5 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 coaxial).
- activate ue test (Parag. 3.12);
- detect the ue signal ∆P (Ref. 16 and 17 Fig.
37);
- compare the signal ∆P and, if necessary,
correct the S1 operating parameters with the
following table:
Victrix Tera 28 1
∆P > 200 Pa
G20 S1 = 126 (6300 rpm)
G31 S1 = 121 (6050 rpm)
Victrix Tera 32 1
∆P > 200 Pa
G20 S1 = 134 (6700 rpm)
G31 S1 = 127 (6350 rpm)
3.6 ADJUSTMENT OF THE AIRGAS
RAT IO.
Attention: the CO2 verication operations must
be carried out with the casing mounted, while the
gas valve calibration operations must be carried
out with the casing open and disconnecting the
boiler from the power supply.
Calibration of the CO2 at minimum output
Enter the chimney sweep mode without withdrawing DHW and set the output to minimum
(0%). To have an exact value of CO2 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 (Part. 3 Fig. 39) (O-Set
adjuster). To increase the CO2 value, turn the
adjustment screw (3) in a clockwise direction
and vice versa to decrease it.
Calibration of the CO2 at maximum output
When you nish the minimum CO2 adjustment,
while maintaining the chimney sweep function
active, set the output to maximum (99%). To
have an exact value of CO2 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 (Part. 12 Fig. 39) (gas ow rate regulator).
To increase the CO2 value, turn the adjustment
screw (12) in a 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.).

Once the function is activated, it is possible to
select whether to make the chick in CH status
or DHW status by opening any hot water cock.
Using the buttons “ ” you can select the
power level between “0%” - Max CH output
(P2) - Max DHW output (P0).
While by using the buttons “ ” you can
select the power from 0% to max DHW output
(P0), with intervals of 1%.
e central heating or DHW operating mode is
displayed by the relative symbols or .
Aer the checks, deactivate the function switching the boiler o and then on again.
3.15 SOLAR PANELS COUPLING
FUNCTION.
The boiler is prepared to receive pre-heated
water from a system of solar panels up to a
maximum temperature of 65°C. In any case, it
is always necessary to install a mixing valve on
the hydraulic circuit upstream of the boiler, on
the cold water inlet.
To optimise the operation,where the probe is
not already tted on the boiler, the solar inlet
probe kit is available on request (see wiring
diagram Fig. 38):
if there is no probe kit, it is advisable to set
parameter A6 (DHW thermostat) at “1”;
otherwise, where the kit is installed or the probe
is already present in the boiler, parameter A6
must be le at “0”. is kit allows connecting
a probe on the domestic cold water inlet pipe
of the boiler to prevent unnecessary ignitions
in systems with water heating through solar
systems or alternative sources. e boiler will
not turn on if the inlet water is suciently hot.
In both conditions (probe present or not), we
recommend setting parameter t3 (solar delay
timing) at a time sucient to let the water inside
the D.H.W. circuit upstream of the boiler drain.
e greater the distance from the storage tank,
the longer wait time will have to be set.
With these adjustments made, when a domestic
withdrawal is requested, once the time set on
parameter “t3” has passed, if the water entering
the boiler is at a temperature that is equal or
greater to that set, the boiler will not turn on.
Note: in order for the boiler to work properly, the
temperature selected on the mixing valve must
be 5°C greater than the temperature selected on
the boiler control panel.
3.16 PUMP ANTIBLOCK FUNCTION.
e boiler has a function that starts the pump at
least once every 24 hours for the duration of 30
seconds in order to reduce the risk of the pump
becoming blocked due to prolonged inactivity.
3.17 THREEWAY ANTIBLOCK SYSTEM
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.
3.18 RADIATORS ANTIFREEZE
FUNCTION.
If the system return water is below 4°C, the boiler
starts up until reaching 42°C.
3.19 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.
- Check the correct positioning, integrity and
cleanliness of the detection and ignition electrode; remove any oxide present.
- If deposits are detected in the combustion
chamber one must remove them and clean
the 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 connections and traces of condensate
residues inside the sealed chamber.
- Check the contents of the condensate drain
trap.
- Check that there are no material residues in
the condensate drain siphon clogging the
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 and gas manifold seal
gaskets 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 blocked.
- Check that, aer discharging the system pres-
sure 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
ba r.
- Check visually that the safety and control
devices have not been tampered with and/or
shorted, in particular:
- Check the condition and integrity of the electrical system and in particular:
- electrical power cables must be inside the
fairleads;
- there must be no traces of blackening or
burning.
- Check correct lighting and operation.
- Ensure correct calibration of the burner in
domestic water and heating phases.
- Check correct operation of control and adjustment devices and in particular:
- system regulation probes intervention;
- domestic hot water control thermostat inter-
vention.
- Check sealing eciency of gas circuit and the
internal system.
- Check the intervention of the device against no
gas ionisation ame control. 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.
