INSTALLATION
1.1 INSTALLATION
RECOMMENDATIONS.
The Victrix 26 2 I boiler has been designed
for wall mounted installation only; for heating
environments and production of domestic hot
water for domestic use and similar purposes.
e installation site and relative Immergas ac-
cessories must have suitable characteristics (both
technical and structural), in order to allow (al-
ways in safe, eciency and easiness conditions):
- installation (according to the legislation and
technical standards in force);
- maintenance operations (including those
scheduled, periodical, ordinary and special);
- removal (to the outdoors in a place suitable
for loading and transporting appliances and
components) as well as any replacement with
equivalent appliances and/or components.
e wall surface must be smooth, without any
protrusions or recesses enabling access to the
rear part. ey are not designed to be installed
on plinths or oors (Fig. 1-1).
By varying the type of installation the
classication of the boiler also varies, precisely:
- Type B23 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 fumes.
Only professionally enabled heating/plumbing
technicians are authorised to install Immergas
gas appliances.
Installation must be carried out according to
regulation standards, current legislation and in
compliance with local technical regulations and
the required technical procedures.
Before installing the appliance, ensure that it
is delivered in perfect condition; if in doubt,
contact the supplier immediately. Packing
materials (staples, nails, plastic bags, polystyrene
foam, etc.) constitute a hazard and must be kept
out of the reach of children. If the appliance
is installed inside or between cabinets, ensure
sucient 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 flue
removal connections. Keep all ammable objects
away from the appliance (paper, rags, plastic,
polystyrene, etc.).
Do not place household appliances underneath
the boiler as they could be damaged if the safety
valve intervenes with the blocked conveyor
system (remember that the safety valve must
always be conveyed away by a draining funnel), or
if there are leaks from the hydraulic connections;
on the contrary, the manufacturer cannot be
held responsible for any damage caused to the
household appliances.
It is also advisable, to not position furnishings,
furniture, etc., under the boiler for the above
mentioned reasons.
In the event of malfunctions, faults or incorrect
operation, turn the appliance o immediately
and contact a qualified technician (e.g. the
Immergas Technical Assistance centre, which
has specically 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:
- is boiler can be installed outdoors in a
partially protected area. A partially protected
area is one in which the appliance is not
exposed to the direct action of the weather
(rain, snow, hail, etc...).
- Installation in places with a fire risk is
prohibited (for example: garages, box), gas
appliances and relative ue ducts, ue exhaust
pipes and combustion air intake pipes.
- Installation is prohibited on the vertical
projection of the cooking surface.
- Installation is also prohibited in places/
environments that constitute common parts
of oce condominiums such as stairs, cellars,
entrance halls, attics, los, escape routes,
etc. if they are not located inside technical
compartments under the responsibility of
each individual building and only accessible
to the user (for the features of the technical
compartments, see the current technical
regulations).
Important: wall mounting of the boiler must
guarantee stable and ecient support for the
generator.
e plugs (standard supply) are to be used only in
conjunction with the mounting brackets or xing
template to x the appliance to the wall; they only
ensure adequate support if inserted correctly
(according to technical standards) in walls made
of solid or semi-hollow brick or block. In the
case of walls made from hollow brick or block,
partitions with limited static properties, or in any
case walls other than those indicated, a static test
must be carried out to ensure adequate support.
N.B.: the hex head screws supplied in the blister
pack are to be used exclusively to x the relative
mounting bracket to the wall.
ese boilers are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a central heating
system and hot water circuit suited to their
performance and capacity.

1.3 ANTIFREEZE 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 4°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;
- the boiler is not in stand-by ( );
- the boiler is not in no ignition block (par. 2.6);
- the boiler essential components are not faulty.
In these conditions the boiler is protected against
freezing to an environmental 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 ignition block), the appliance
can freeze.
To prevent the risk of freezing follow the
instructions below:
- protect the central heating circuit from freezing
by introducing a top quality anti-freeze liquid
into this circuit, which is not noxious to 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.
e materials used for the central heating circuit
of Immergas boilers resist 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 circuit
board against freezing by using an accessory
that is supplied on request (anti-freeze kit)
comprising two electric heating elements,
the relevant cables and a control thermostat
(carefully read the installation instructions
contained in the accessory kit pack).
Boiler anti-freeze protection is thus ensured only if:
- the boiler is correctly connected to gas and
electricity power supply circuits and powered;
- the anti-freezing kit components are ecient.
In these conditions the boiler is protected against
freezing to temperature of -15°C.
The 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 water
and heating attachment pipes must be insulated.

CAVO ALIMENTAZIONE
INSTALLATORUSER
MAINTENANCE TECHNICIAN
1.4 CONNECTION UNIT SUPPLIED AS
STANDARD WITH THE BOILER.
Gas connection (Appliance category II2H3B/P).
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 eciency. Also
make sure the gas corresponds to that for which
the boiler is prepared (see boiler data-plate).
If dierent, 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 LPG) pressure
must also be checked according to the type used
in the boiler, which must be in compliance, as
insucient levels can reduce generator output
and cause malfunctions.
Ensure correct gas cock connection. e gas
supply pipe must be suitably dimensioned
according to current regulations in order to
guarantee correct gas ow to the burner even
in conditions of maximum generator output
and to guarantee appliance eciency (technical
specifications). The coupling system must
conform to standards.
Fuel gas quality. The appliance has been
designed to operate with gas free of impurities;
otherwise it is advisable to fit special filters
upstream from the appliance to restore the
purity of the gas.
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.
Hydraulic connection.
Attention: In order not to void the warranty
before making the boiler connections, carefully
clean the heating system (pipes, radiators, etc.)
with special pickling or de-scaling products to
remove any deposits that could compromise
correct boiler operation.
A chemical treatment for the thermal system
water is prescribed according to the current
technical regulations, until the system and the
lime scale apparatus is preserved (for example,
limescale deposits), from the slurry formation
and other noxious deposits.
Water connections must be made in a rational
way using the couplings on the boiler template.
e boiler safety valve outlet must be connected
to a draining funnel. Otherwise, the manufacturer
declines any responsibility in case of ooding if
the drain valve cuts in.
Important: to preserve the duration of appliance
eciency features, in the presence of water whose
features can lead to the deposit of lime scale,
installation of the “polyphosphate dispenser” kit
is recommended.
Condensate drain. To drain the condensate
produced by the appliance, it is necessary
to connect to the drainage system by means
of acid condensate resistant pipes having an
internal diameter 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 start-up, ensure that the condensate
can be correctly removed. Also, comply with
national and local regulations on discharging
waste waters.
Electrical connection: e “Victrix 26 2 I” boiler
has an IPX4D protection rating for the entire
appliance. Electrical safety of the appliance is
reached only when it is correctly connected to an
ecient earthing system as specied 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
ecient earth system or failure to comply with
the reference standards.
Also ensure that the electrical installation
corresponds to maximum absorbed power
specications as shown on the boiler data-plate.
Boilers are supplied complete with an “X” type
power cable without plug. e power supply
cable must be connected to a 230V ±10%/ 50Hz
mains supply respecting L-N polarity and earth
connection . is network must also have
an omnipolar circuit breaker with class III over-
voltage category.
To protect against possible voltage dispersions,
it is necessary to envision a dierential safety
device type A.
When replacing the power supply cable, contact
a qualied technician (e.g. the Immergas Aer-
Sales Technical Assistance Service). e power
cable must be laid as shown (Fig. 1-3).
In the event of mains fuse replacement on the
P.C.B., use a 3.15A quick-blow fuse. For the
main power supply to the appliance, never use
adapters, multiple sockets or extension leads.

1.5 REMOTE CONTROLS AND
ROOM CHRONOTHERMOSTATS
OPTIONAL.
e boiler is prepared for the application of room
chrono-thermostats or remote controls, which
are available as optional kits. (Fig. 1-4)
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the accessory
kit.
• On/O digital chrono-thermostat. e chrono-
thermostat allows:
- to set two room temperature values: one for
day (comfort temperature) and one for night
(lower temperature);
- set a weekly program with four daily switch-on/
o;
- selecting the required function mode from the
various possible alternatives:
- manual operation (with adjustable tempera-
ture).
- automatic operation (with set program).
- forced automatic operation (temporarily
modifying the temperature of the automatic
program).
e chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control
DeviceV2 CARV2) (Fig. 1-4) 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 of easily intervening on the
previously set parameters without having to
go to the place where the appliance is installed.
The Comando Amico RemotoV2 Remote
Control panel is provided with self-diagnosis
to display any boiler operating anomalies.
e 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. It also allows to display the
eective room temperature and the external
temperature (if external probe is present).
e chrono-thermostat is fed directly by the
boiler by means of the same 2 wires used for
the transmission of data between boiler and
chrono-thermostat.
Important: if the system is divided into zones
using the relevant kit. the CAR V2 must be used
with its climate thermostat function disabled, i.e.
it must be set to On/O mode.
CARV2 or chrono-thermostat On/O electric
connection (Optional). e operations described
below must be performed aer having removed
the voltage from the appliance. The eventual
On/O environment chrono-thermostat must
be connected to clamps 40 and 41 eliminating
jumper X40 (Fig. 1-5). Make sure that the On/
O thermostat contact is of the “clean” type,
i.e. independent of the mains supply, otherwise
the P.C.B. would be damaged. Any CARV2 must
be connected by means of terminals +and - to
clamps 41 and 44 on the P.C.B. (in boiler),
eliminating jumper X40 and respecting polarity
(Fig. 1-5). Connection with the wrong polarity
prevents functioning, but without damaging the
CARV2. e boiler can only be connected to one
remote control.
Important: If the CARV2 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 this risk
is eliminated before making the boiler electrical
connections.
Installation with system operating at direct
low temperature. e boiler can directly feed a
low temperature system by acting on parameters
“S5” and S6” (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.
1.6 EXTERNAL PROBE OPTIONAL.
e boiler is prepared for the application of the
external probe (Fig. 1-6), which is available as an
optional kit. Refer to the relative instruction sheet
for positioning of the external probe.
The 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. 1-7). e electric connection of
the external probe must be made on clamps 38
and 39 on the terminal board positioned under
the sealed chamber (Fig. 3-2).

1.7IMMERGAS FLUE SYSTEMS.
Immergas supplies various solutions separately
from the boilers regarding the installation of air
intake terminals and ue extraction, which are
fundamental for boiler operation.
Attention: the boiler must be installed
exclusively with an original Immergas “Green
Range” air intake and fume extraction system
in plastic, as envisioned by Standard in force.
e plastic pipes cannot be installed outdoors,
for tracts longer than 40cm, without suitable
protection fromUV rays and otheratmospheric
agents.
This system can be identified by an
identification mark and special distinctive
marking bearing the note: “only for condensing
b o i l e r s ”.
• Resistance factors and equivalent lengths.
Each ue component has a Resistance Factor
based on experimental tests and specified
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, obtained from the
ratio between the relative Resistance Factors.
All boilers have an experimentally obtainable
maximum Resistance Factor equal to 100.
The maximum Resistance Factor allowed
corresponds to the resistance encountered with
the maximum allowed pipe length for each
type of Terminal Kit. is information allows
calculations to be made to verify the possibility
of setting up various ue congurations.
• Positioning of the gaskets (black) for “green
range” ue extraction systems. Position the
gasket correctly (for bends and extensions)
(Fig. 1-8):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for
extensions.
N.B.: if component lubrication (already carried
out by the manufacturer) is not sufficient,
remove the residual lubricant using a dry cloth,
then to ease tting spread the elements with
common or industrial 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 section
(with lip seal) to the end stop on the previously
installed element in order to ensure sealing
eciency of the coupling.
Attention: if the exhaust terminal and/or
extension concentric 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
temporarily.
• N.B.: when installing horizontal pipes,
a minimum inclination of 3%must be
maintained and a section clamp with pin must
be installed every 3 metres.
