1.3 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 by follow-
ing the mounting instructions illustrated in
the figure. The gas supply pipe must be suitably
dimensioned according to current regulations in
order to guarantee correct gas flow to the burner
even in conditions of maximum generator output
and to guarantee appliance efficiency (technical
specifications). The coupling system must con-
form 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 on the primary heat
exchanger (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.
On/Off digital chronothermostat
Hydraulic connections must be made in a
). rational way using the couplings on the boiler
2H3+
template. The boiler safety valve outlet must be
connected to an appropriate drain. Otherwise,
the manufacturer declines any responsibility in
case of flooding if the drain valve cuts in.
Important: to preserve the duration of appliance
efficiency 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 softeners
for powers > 100 kW.
Electrical connection. The Mini Nike X 24 3 E
boiler has an IPX4D 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 cor-
responds to maximum absorbed power specifica-
tions 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 mains sup-
ply respecting L-N polarity and earth connection
. This network must also have an omnipolar
circuit breaker with class III over-voltage cat-
egory. When replacing the power supply cable,
contact a qualified technician (e.g. the Immergas
After-Sales Technical Assistance Service). The
power cable must be laid as shown. In the event
of mains fuse replacement on the P.C.B., use a
2A quick-blow fuse. For the main power supply
to the appliance, never use adapters, multiple
sockets or extension leads.
1.4 REMOTE CONTROLS AND
ROOM CHRONOTHERMOSTATS
(OPTIONAL).
The boiler is prepared for the application of room
chronothermostats or remote controls, which are
available as optional kits.
All Immergas chronothermostats can be con-
nected with 2 wires only. Carefully read the
user and assembly instructions contained in the
accessory kit.
• On/Off digital chronothermostat (Fig. 1-5). The
chronothermostat allows:
- to set two room temperature values: one for
day (comfort temperature) and one for night
(lower temperature);

- to set up to four on/off differential 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.
The chronothermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control De-
vice (CAR ) with climate chronothermostat

function. In addition to the functions described
in the previous point, the CAR panel
the user to control all the important informa-
tion regarding operation of the appliance and
the heating system with the opportunity of eas-
ily intervening on the previously set parameters
without having to go to the place where the ap-
pliance is installed. The panel is provided with
self-diagnosis to display any boiler functioning
anomalies. The climate chronothermostat in-
corporated into the remote panel enables the
system flow 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. The chronothermostat
is fed directly by the boiler by means of the
same 2 wires used for the transmission of data
between boiler and chronothermostat.
Important: If the system is subdivided into zones
using the relevant kit. the CAR
with its climate thermostat function disabled, i.e.
it must be set to On/Off mode.
Comando Amico Remoto remote control
or On/Off chronothermostat electrical con-
nections (Optional). The operations described
below must be performed after having removed
the voltage from the appliance. Any thermostat
or On/Off environment chronothermostat must
be connected to clamps 40 and 41 eliminating
jumper X40 (Fig. 3-2). Make sure that the On/
Off thermostat contact is of the "clean" type, i.e.
independent of the mains supply, otherwise the
electronic adjustment card would be damaged.
Any Comando Amico Remoto remote control
must be connected to clamps 40 and 41 elimi-
nating jumper X40 on the circuit board, paying
attention not to invert the connections (Fig. 3-2).
Important: if the Comando Amico Remoto
remote control or any other On/Off chrono-
V2
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 mak-
ing the boiler electrical connections.
