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 suci
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 (Fig. 3).
It is just as important that the intake grids and exhaust
terminals are not obstructed.
It is recommended to check that no ue gas recirculation is found in the air sample points (0.5% maximum
permitted CO2).
Keep all ammable objects away from the appliance
(paper, rags, plastic, polystyrene, etc.).
e minimum distance for exhaust pipes from am-
mable materials must be at least 25 cm.
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

1.4 ANTIFREEZE PROTECTION.
Minimum temperature -15°C. If the boiler is installed
in a place where the temperature drops below 0°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
INSTALLER
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.
N.B.: the excessive use of glycol could jeopardise the proper
functioning of the appliance.
An aqueous solution must be made with potential pollution
class of water 2 (EN 1717:2002).
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).
USER
For life and possible disposal, follow the supplier'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 (Par. 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
lectrical power supply and failure to comply with that stated
e
MAINTENANCE TECHNICIAN
on the previous page.
Note: if the boiler is installed in places where the temperature
falls below 0°C the domestic hot water and central heating
attachment pipes and the condensate drain pipe must be
insulated.
Note: the antifreeze systems described in this chapter are
only to protect the boiler. e presence of these functions and
devices does not exclude the possibility of parts of the system
or domestic hot water circuit outside the boiler from freezing.

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 a standard supply. Perform the connections respecting
the layout of (Fig. 4) based on the type of installation to be made.
1.6 GAS CONNECTION.
Our boilers are designed to operate with methane gas (G20) and
L.P.G. Supply pipes must be the same as or larger than the 3/4”G
boiler tting.
ATTENTION:
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 dy-
mic pressure of the mains (metha
na
ne 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.
According to local regulations in force,
make sure that a gas cock is installed
upstream of each connection between
the appliance and the gas system. is cock,
if supplied by the appliance’s manufacturer,
can be directly connected to the appliance
(i.e. downstream from the pipes connecting
the system to the appliance), according to the
manufacturer’s instructions.
The Immergas connection unit, which is a
standard supply, also includes the gas cock,
whose installation instructions are provided
in the kit.
In any case, make sure the gas cock is connected properly.
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 (EN 1775).
ATTENTION:
the appliance is designed to operate with
fuel gas free from impurities; otherwise
it is advisable to t special lters upstream of
the appliance to restore the purity of the fuel.

Storage tanks (in case of supply from LPG depot).
- New LPG storage tanks may contain residual inert gases (nitrogen) that degrade the mixture delivered to the appliance casing
functioning anomalies.
- Due to the composition of the LPG mixture, layering of the
mixture components may occur during the period of storage in
the tanks. is can cause a variation in the caloric value of the
mixture delivered to the appliance, with subsequent change in
its performance.

1.7 HYDRAULIC CONNECTION.
In order not to void the condensation module warranty before making the boiler connections, carefully
clean the heating system (pipes, radiators, etc.) with
special pickling or descaling products to remove
any deposits that could compromise correct boiler
operation.
ATTENTION:
the manufacturer 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 boil-
er's primary circuit (C.H. circuit), as dened in standard EN 1717.
To preserve the duration of appliance eciency features, in the presence of water whose features can
lead to the deposit of lime scale, installation of the
“polyphosphate dispenser” kit is recommended .
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
USER
exchanger warranty, you are required to comply with what has
been prescribed in (Par. 1.22.
Water connections must be made in a rational way using the
couplings on the boiler template.
3 bar safety valve.
Safety valve (Part. 5 Fig. 32) discharge must always be conveyed
through a draining funnel. Consequently, in the event of valve
intervention, the discharged liquid will end up in the sewer system.
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. 1.24). 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:
the manufacturer declines any responsibility for damage or physical injury
caused by failure to connect the boiler
to an ecient earthing system or failure
to comply with the IEC reference standards.
• Open the control panel connections compartment (Fig. 6).
To carry out electrical connections, all you have to do is open
the connections compartment as follows.
- Remove the front panel (Fig. 49).
- Remove the cover (Ref. b Fig. 6).
1) Loosen the two screws (a).
2) Press the two hooks on the cover (b).
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.
ATTENTION:
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 in
compliance with installation regulations.
To protect from possible dispersions of DC voltage, it is necessary
to provide a type A dierential safety device.
If the power supply cable is damaged, it must be replaced by a
special cable or assembly, which are only available from the manufacturer or its Aer-sales Service. It is recommended to contact
a qualied company (e.g. the Immergas Authorised Aer-Sales
Technical Assistance Service) for replacement to avoid a hazard.
e power cable must be laid as shown (Fig. 5).
If the network fuse on the connection terminal block needs replacing, this must also be done by qualied personnel: use a 3.15
A fast 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. 3.15). In
this situation it is good practice to insert a relevant safety kit (optional) made up from a thermostat (with adjustable temperature).
Execute connection to terminal boards 14 and 15, eliminating
jumper X70 (Fig. 36). 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 CHRONO
THERMOSTATS OPTIONAL.
The boiler is prepared for the application of room chronothermostats or remote controls, which are available as optional
kits (Fig. 7).
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 temper-
INSTALLER
ature) 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 mode (with adjustable temperature).
• automatic mode (with set programme).
• forced automatic mode (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 Device V2 (CARV2)
with climate chrono-thermostat function.
USER
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. 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. e CAR
same 2 wires used for the transmission of data between the boiler
and device.
If the system is divided into zones using the relevant
kit, the CARV2 must be used with its climate thermostat
function disabled, i.e. it must be set to On/O mode.
V2
is fed directly by the boiler by means of the
Comando Amico Remoto Remote Control V2 or On/Off
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 40
and 41 eliminating jumper X40 (Fig. 36). 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 terminals 44 and 41, eliminating jumper X40 on the P.C.B.
(Fig. 36).
If the Comando Amico Remoto remote control V2 or
any other On/O 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.
1.10 EXTERNAL TEMPERATURE PROBE OPTIONAL.
e boiler is designed for the application of the external temperature probe (Fig. 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 external probe always operates when
connected, regardless of the presence or type of room chronothermostat 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. 9). 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. 36).

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
ue gas extraction system made of plastic,
with the exception of the C6 conguration, as
required by the regulations in force and by the
product’s approval.
is ue can be identied by an identication
rk and special distinctive marking bearing
ma
the note "only for condensation boilers".
e plastic pipes cannot be installed outdoors,
f
or tracts longer than 40 cm, without suitable
protection from UV rays and other atmospheric agents.
• Resistance factors and equivalent lengths.
Each ue component has a Resistance Factor based on experi-
mental 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 resist-
ance 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 Resist-
ance 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. is information allows calculations to be made to verify the possibility of setting up various
ue congurations.
Note: to dimension the ue duc
nents, refer to the table of combustion parameters (Paragraph 4.2).

• Positioning the gaskets (black) for “green range” ue systems.
Position the gasket correctly (for bends and extensions) (Fig. 10):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for extensions.
N.B.: if necessary, to ease the push-tting, spread the elements
with commonly-used talc.
• Extension pipes and concentric elbows push-ttings.
To install push-tting extensions with other elements of the ue
extraction elements assembly, 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.
N.B.: 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.
e various parts of the ue system must be checked
to ensure that they have been laid in such a way as
to prevent the coupled parts from detaching, in particular, the ue exhaust duct in the Ø80 separator kit
conguration. Should the aforesaid condition not be
adequately guaranteed, it will be necessary to use the
special clamp ring nut clip kit.
N.B.: when installing horizontal pipes, a minimum inclination
of 3% towards the boiler must be maintained, and a section clip
with pin must be installed every 3 metres.
