1 BOILER INSTALLATION.
1.1 INSTALLATION
RECOMMENDATIONS.
e Hercules Condensing boiler has been de-
signed uniquely for oor-installation, for the
heating of rooms for domestic use and similar.
In the event the appliance is installed in humid
environments, an insulation system must be
provided underneath from the laying surface.
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.
By varying the type of installation the classica-
tion of the boiler also varies, precisely:
- Type B boiler23 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 qualied heating/plumbing
technicians are authorised to install Immergas
gas appliances.
Installation must be carried out according to the
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 (sta-
ples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children. If the appliance is installed in-
side or between cabinets, ensure sucient space
for normal servicing; therefore it is advisable to
leave clearance of at least 30 cm on the right of
the boiler in order to open the lateral hatch and a
space of 3 cm between the remaining sides of the
boiler and the sides of the cabinet. Leave adequate
space above the boiler for possible water and
fume removal connections. Keep all ammable
objects away from the appliance (paper, rags,
plastic, polystyrene, etc.).

In the event of malfunctions, faults or incorrect
operation, turn the appliance o immediately and
contact a qualied technician (e.g. the Immergas
Technical Assistance centre, which has specical-
ly 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:
- Installation in places with a re risk is pro-
hibited (for example: garages, box), gas ap-
pliances and relative ue ducts, ue exhaust
pipes and combustion air intake pipes.
- Installation is also prohibited in places/en-
vironments 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.
Important: these 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. ey must be
installed in rooms where the temperature can-
not fall below 0°C and must not be exposed to
atmospheric agents.

INSTALLATORUSERMAINTENANCE
Anti-Legionella thermal treatment of the Im-
mergas storage tank (which can be activated
through the specic function present on the set
thermoregulation systems): during this phase,
the water temperature inside the storage tank ex-
ceeds 60 °C resulting in burns hazards. Keep this
DHW treatment under control (and inform the
users), to prevent unexpected damage to persons,
animals and objects. If required, a thermostatic
valve must be installed at the DHW outlet to
prevent burns.
1.3 ATTACHMENTS.
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 conver-
ting 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, as insucient levels can reduce generator
output and cause malfunctions. Ensure correct
gas cock connection.
e gas supply pipe must be suitably dimensio-
ned 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 speci-
cations). e coupling system must conform
to standards.
Fuel gas quality. e appliance has been desig-
ned to operate with gas free of impurities; other-
wise it is advisable to t special lters 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 causing 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.
Important: 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.
In compliance with Standards in force it is man-
datory to treat the water in the heating system
chemically in order to protect the system and
appliance from deposits of lime scale.
Water connections must be made in a rational
way using the couplings on the boiler template.
e boiler safety valves outlet must be connected
to a draining funnel. Otherwise, the manufactu-
rer 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. On the basis of the Standards in
force, it is mandatory to treat the water with over
25 French degrees in the heating circuit and over
15 French degrees for DHW using conditioning
chemicals for powers < 100 kW or with soeners
for powers > 100 kW.
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 dia-
meter 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 “Hercules Conden-
sing” boiler has an IPX5D protection rating
for the entire appliance. Electrical safety of the
appliance is reached only when it is correctly
connected to an efficient earthing system as
specied by current safety standards.
Important: Immergas S.p.A. declines any re-
sponsibility for damage or physical injury caused
by the failure to connect the boiler to an ecient
earthing system or failure to comply with the
reference standards.
Also ensure that the electrical installation corre-
sponds to maximum absorbed power specica-
tions as shown on the boiler data-plate.
e 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 over-voltage category. When replacing
the power supply cable, contact a qualied tech-
nician (e.g. the Immergas Aer-Sales Technical
Assistance Service).
e power cable must be laid as shown.
In the event of mains fuse replacement on the
control card, use a 3.15A quick-blow fuse. For
the main power supply to the appliance, never

1.4 REMOTE CONTROLS AND
ROOM TIMER THERMOSTATS
OPTIONAL.
e boiler is prepared for the application of room
timer thermostats or remote controls, which are
available as optional kits.
All Immergas timer thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the acces-
sory kit.
• On/O digital timer thermostat (Fig. 1-3). e
timer thermostat allows:
- to set two room temperature values: one for
day (comfort temperature) and one for night
(lower temperature);
- to set up to four on/o dierential weekly
programs;
- to select the required operating mode from
the various possible alternatives:
• permanent functioning in comfort temp.
• permanent functioning in reduced temp.
• permanent functioning in adjustable anti-
freeze temp.
e timer thermostat is powered by two 1.5V
LR 6 type alkaline batteries;
• ere are two types of remote controls availa-
ble: Comando Amico Remoto remote controlV2
(CARV2) (Fig. 1-3) and Super Comando Amico
Remoto remote control (Super CAR) (Fig. 1-4)
both with room timer thermostat functioning.
In addition to the functions described in the
previous point, the timer thermostat panels
enable the user to control all the important
information regarding operation of the ap-
pliance and the central heating system with
the opportunity of easily intervening on the
previously set parameters without having to go
to the place where the appliance is installed. e
panel is provided with self-diagnosis to display
any boiler functioning anomalies. e climate
timer 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 timer thermostat is fed directly by
the boiler by means of the same 2 wires used
for the transmission of data between boiler and
timer thermostat.
Important: if the system is subdivided into
zones using the relevant kit the CARV2 and the
Super CAR must be used with its climate ther-
mostat function disabled, i.e. it must be set to
On/O mode.
CARV2, Super CAR or On/O timer thermostat
electrical connection (Optional). e operations
described below must be performed aer having
removed the voltage from the appliance. e even-
tual On/O environment timer thermostat must
be connected to clamps 40 and 41 eliminating
jumper X40 (Fig. 3-2). Make sure that the On/
O thermostat contact is of the “clean” type, i.e.
independent of the mains supply, otherwise the
electronic adjustment card would be damaged.
Any CARV2 or Super CAR must be connected
by means of terminals IN+ and IN- to terminals
42 and 43 on the P.C.B. (in boiler), eliminating
jumper X40 and respecting polarity (Fig. 3-2).
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 Comando Amico Remoto
remote controlV2 is used, arrange two separate
lines in compliance with current regulations
regarding electrical systems. Boiler pipes must
never be used to earth the electric or telephone
lines. Ensure elimination of this risk before ma-
king the boiler electrical connections.
Installation with system operating at direct
low temperature. e boiler can directly feed a
low temperature system by acting on parameter
“P66” (Par. 3.8) and setting the ow temperature
adjustment range“P66/A” and “P66/B”. In this si-
tuation it is good practice to insert a safety device
in series with the power supply and boiler. is
device is made up from a thermostat with a tem-
perature limit of 60°C. e thermostat must be
positioned on the system ow pipe at a distance
of at least 2 metres from the boiler.
1.5 EXTERNAL TEMPERATURE PROBE
OPTIONAL.
e boiler is prepared for the application of the
external probe (Fig. 1-5), which is available as an
optional kit. e probe can be connected directly
to the boiler electrical system and allows the
max. system ow temperature to be automati-
cally 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 timer thermostat used and can
work in combination with Immergas timer
thermostats. e correlation between system
ow temperature and external temperature is
determined by the parameters set in menu “M5”
under “P66” according to the curves represented
in the diagram (Fig. 1-6). e electric connection
of the external probe must be made on clamps 38
and 39 on the boiler P.C.B. (Fig. 3-2).

1.6 IMMERGAS 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 40 cm, without suitable
protection from UV rays and other atmospheric
agents.
This system can be identified by an
identification mark and special distinctive
marking bearing the note: “only for condensing
boilers”.
• Resistance factors and equivalent lengths.
Each ue component has a Resistance Factor
based on experimental tests and 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. 1-7):
- 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.

1.8 INSTALLATION OF BOILER TYPE
B23OPEN CHAMBER AND FAN
ASSISTED.
In this conguration the relevant terminal “1”
must be used (present in the appropriate intake
kit for the installation in question) to be placed
on the intake hole above the sealed chamber
(Fig. 1-8). Air intake takes place directly from the
environment and ue exhaust in individual ue
or to the outside. e boiler in this conguration,
following the assembly instructions stated on the
relative instruction sheet, is classied as type B23.
With this conguration:
- air intake takes place directly from the environ-
ment in which the boiler is installed and only
functions in permanently ventilated rooms;
- the ue exhaust must be connected to its own
individual ue or channelled directly into the
external atmosphere.
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours or
substances (e.g. acid vapours, glues, paints, sol-
vents, combustibles, etc.), as well as dusts (e.g.
dust deriving from the working of wood, coal
nes, cement, etc.). ese may be damaging for
the components of the appliance and jeopardise
functioning.
The technical regulations in force must be
respected.
Max. length of exhaust duct. The flue pipe
(vertical or horizontal) can be extended to a max.
length of 30 straight metres.

1.9 HORIZONTAL CONCENTRIC KIT
INSTALLATION.
Type C configuration, sealed chamber and
fan assisted.
Horizontal intake - exhaust kit Ø 60/100.
Assembly kit (Fig. 1-9): install the bend with
ange (2) on the most internal hole of the boiler,
placing the gasket (1) (which does not require
lubrication); positioning it with the circular
projections downwards in contact with the boiler
ange and tighten using the screws present in the
kit. Fit the Ø 60/100 (3) concentric terminal pipe
with the male end (smooth) to the female end
of the bend (2) up to the stop; making sure that
the internal and external wall sealing plates have
been tted, this will ensure sealing and joining
of the elements making up the kit.
• Extensions for horizontal kit Ø60/100
(Fig. 1-10). e kit with this conguration
can be extended up to a max. horizontal
distance of 12.9 m including the terminal with
grid and excluding the concentric bend leaving
the boiler. is conguration corresponds to
a resistance factor of 100. In these cases the
special extensions must be requested.
Horizontal intake - exhaust kit Ø80/125. Kit
assembly (Fig. 1-11): for the installation of kit
Ø80/125 the anged adapter kit must be used to
be able to install the ue system Ø80/125. Install
the anged adapter (2) on the most internal hole
of the boiler, positioning the gasket (1) (which
does not require lubrication) with the circular
projections downwards in contact with the boiler
ange and tighten using the screws present in
the kit. Engage the bend (3) with the male side
(smooth) until it is fully home on the adapter (1).
Fit the Ø80/125 (5) concentric terminal pipe with
the male end (smooth) to the female end of the
bend (4) (with lip seal) up to the stop; making
sure that the internal (6) and external wall sealing
plates (7) have been tted, this will ensure sealing
and joining of the elements making up the kit.
• Extensions for horizontal kit Ø80/125
(Fig. 1-12). e kit with this conguration
can be extended up to a max. distance of 32 m
including the terminal with grid and excluding
the concentric bend leaving the boiler. If
additional components are assembled, the
length equivalent to the maximum allowed
must be subtracted. In this case the special
extensions must be requested.
• External grid. N.B.: for correct functioning
of the system the terminal with grid must be
installed correctly ensuring that, the "high"
indication present on the terminal is respected
on installation.

is terminal enables the air intake and the ue
exhausts to be directly emitted outside the house
in a vertical direction.
N.B.: the vertical kit with aluminium tile
enables installation on terraces and roofs with
a maximum slope of 45% (approximately 25°)
and the height between the terminal cap and
half-shell (374 mm for Ø60/100 and 260 mm for
Ø80/125) must always be respected.
