1.3 ANTI-FREEZE PROTECTION.
Minimum temperature -5°C. The boiler is sup-
ES
plied with an antifreeze function as standard that
activates the pump and burner when the system
water temperature in the boiler falls below 4°C.
PT
The anti-freeze function is only guaranteed if:
- the boiler is correctly connected to gas and
electricity power supply circuits;
- the boiler is powered constantly;
GR
- the boiler is not in no ignition block
(Par. 2.5);
- the boiler essential components are not
PL
faulty.
In these conditions the boiler is protected against
freezing to an environmental temperature of
-5°C.
TR
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
CZ
the boiler goes into ignition block, the appliance
can freeze.
To prevent the risk of freezing follow the instruc-
tions below:
SI
- protect the central heating circuit from freez-
ing by introducing a good quality anti-freeze
liquid (specifically for central heating systems),
carefully following the manufacturer's instruc-
HU
tions regarding the percentage necessary with
respect to the minimum temperature required
for preserving the system.
RU
The materials the boilers are made from are
resistant to ethylene and propylene glycol-based
anti-freeze liquids.
For life and possible disposal, follow the supplier's
RO
instructions.
- Protect the domestic hot water circuit against
freezing by using an accessory that is supplied
on request (anti-freeze kit) comprising two
IE
electric heating elements, the relevant cables
and a control thermostat (carefully read the
installation instructions contained in the ac-
cessory kit pack).
SK
Boiler anti-freeze protection is thus ensured
only if:
- the boiler is correctly connected to electricity
UA
power supply circuits;
- main switch is inserted;
- the anti-freeze kit components are efficient.
In these conditions the boiler is protected against
freezing to temperature of -15°C.
The warranty does not cover damage due to inter-
ruption 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 heating attach-
ment pipes must be insulated.

1.4 CONNECTIONS.
Gas connection (Appliance category II
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 fitting.
Before connecting the gas line, carefully clean
inside all the fuel feed system pipes to remove any
residue that could impair boiler efficiency. Also
make sure the gas corresponds to that for which
the boiler is prepared (see boiler data-plate). If
different, the appliance must be converted for op-
eration with the other type of gas (see converting
appliance for other gas types). The dynamic gas
supply (methane or LPG) pressure must also be
checked according to the type used in the boiler,
as insufficient levels can reduce generator output
and cause malfunctions.
Ensure correct gas cock connection. The gas sup-
ply pipe must be suitably dimensioned according
to current regulations in order to guarantee cor-
rect gas flow to the burner even in conditions of
maximum generator output and to guarantee ap-
pliance efficiency (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. This
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 order to prevent scaling in the heating system,
). the provisions given in the regulations regarding
2H3+
water treatment in heating systems for civil use
must be respected.
Hydraulic connections must be made in a
rational way using the couplings on the boiler
template. The boiler safety valves outlet must be
connected to a draining funnel. Otherwise, the
manufacturer declines any responsibility in case
of flooding if the drain valves cut in.
Important: to preserve the duration and efficiency
of the domestic hot water exchanger it is recom-
mended to install the "polyphosphate dispenser"
kit in the presence of water whose characteristics
can give rise to scale deposits (in particular, and as
an example, the kit is recommended when water
hardness is higher than 25 French degrees).
Electrical connection. The "Mini Eolo X 24 3 E"
boiler has an IPX5D protection rating for the
entire appliance. Electrical safety of the unit is
reached when it is correctly connected to an
efficient earthing system as specified by current
safety standards.
Important: Immergas S.p.A. declines any re-
sponsibility for damage or physical injury caused
by failure to connect the boiler to an efficient
earth system or failure to comply with the refer-
ence standards.
Also ensure that the electrical installation
corresponds to maximum absorbed power
specifications as shown on the boiler data-plate.
Boilers are supplied complete with an "X" type
power cable without plug. The power supply cable
must be connected to a 230V ±10% / 50Hz net-
work respecting the L-N polarity and the earth
connection . An omnipolar disconnection
must be envisioned on this network with a class
III overvoltage category. When replacing the
power supply cable, contact a qualified techni-
cian (e.g. the Immergas After-Sales Technical
Assistance Service). The power cable must be
laid as shown.
In the event of mains fuses replacement on
the connection board, use a 3.15A quick-blow
fuses. For the main power supply to the appli-
ance, never use adapters, multiple sockets or
extension leads.
