Attention:
wall mounting of the boiler must
guarantee stable and efficient support for the
generator.
The plugs (standard supply) are to be used only in
conjunction with the mounting brackets or fixing
template to fix 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 fix the relative
mounting bracket to the wall.
These boilers are used to heat water to below
boiling temperature in atmospheric pressure.
They must be connected to a central heating
system and hot water circuit suited to their
performance and capacity.
They cannot be connected directly to low-
temperature systems.
1.3 GAS CONNECTION.
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 de-
signed to operate with gas free of impurities; oth-
erwise 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.
1.4 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.
A treatment of the heating and water system wa-
ter 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.
Hydraulic connections must be made in a
rational way using the couplings on the boiler
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.
Attention: the manufacturer declines all liability
in the event of damage caused by the installation
of an automatic filling system .
In order to meet the system requirements es-
tablished by the technical regulation in force in
relation to the pollution of drinking water, we
recommend installing the IMMERGAS anti-
backflow kit to be used upstream of the cold
water inlet connection of the boiler. It is also
recommended that the heat transfer fluid (e.g.
water + glycol) entered in the primary circuit
of the boiler (heating circuit), complies with the
local regulations in force.
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.
1.5 ELECTRICAL CONNECTION.
The Mini Nike X 24 3 E boiler has an IPX4D
protection rating for the entire appliance. Elec-
trical safety of the unit is reached when it is cor-
rectly connected to an efficient earthing system
as specified by current safety standards.
Important: the manufacturer declines any
responsibility for damage or physical injury
caused by failure to connect the boiler to an
efficient earth system or failure to comply with
the reference 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 mains supply respecting L-N polarity and
earth connection . This network must also
have an omnipolar circuit breaker with class III
over-voltage category. When replacing the power
supply cable, contact an authorised company (e.g.
Authorised Technical After-Sales 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.
1.6 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. (Fig. 1-3)
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 chrono-thermostat. The chro-
no-thermostat allows:
- set two room temperature value: one for day
(comfort temperature) and one for night
(reduced temperature);
- set a weekly programme with four daily
switch on and switch off 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).
The chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• “Comando Amico Remoto” remote Control
Device
V2
(CAR
V2
) with climate chronother-
mostat function. In addition to the functions
described in the previous point, the CAR
panel
V2
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 panel is provided with self-diagnosis to
display any boiler functioning anomalies.
The climate chronothermostat incorporated
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. CAR
V2
is powered directly by
the boiler via the same 2 wires that are used
for data transmission between the boiler and
the device.
Important:
If the system is subdivided 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/Off mode.
