1 GENERAL INFORMATION
1.1 General Safety Information
b
After removing the packaging, check the condition
and completeness of the supply. If there are any
problems, contact the company Bthat sold the
equipment.
b
This product must be installed by a legally qualified
heating engineer. On completion of the installation,
the installer must issue the owner with a declaration
of conformity confirming that the installation has been
completed to the highest standards in compliance
with the instructions provided by Bin this instruc-
tion manual, and that it conforms to all applicable
laws and standards.
b
This product must only be used for the purpose
for which it is designed and made, as specified by
B. Bdeclines all responsibility, contractual or
other, for damage to property or injury to persons or
animals caused by improper installation, adjustment,
maintenance or use.
b
In the case of water leaks, disconnect the modular
condensing system from the mains electrical supply,
close the water supply and promptly inform the Tech-
nical Assistance Centre Bor professionally qual-
ified personnel.
b
Periodically check that operating pressure in the wa-
ter circuit is over 1 bar but below the maximum limit
specified for the boiler. If this is not the case, contact
Technical Assistance Centre Bor a professionally
qualified heating engineer.
b
The following operations shall be necessary if the
modular condensing system is not used for a long
period of time:
- Switch the boiler OFF at the control panel
- Turn the main system switch "off"
- Close the fuel cock and heating circuit water cock
- Drain the central heating circuit if there is any risk of
freezing.
b
Maintenance must be performed on the modular con-
densing system at least once a year.
b
This manual is an integral part of the equipment and
therefore must be stored carefully and must ALWAYS
accompany the modular condensing system even if
it is sold to another Owner or User or transferred to
another plant. If it is damaged or lost, request anoth-
er copy from your local Technical Assistance Centre
B.
1.2 Precautions
The operation of any appliance that uses fuel, electrical
power and water demands that a number of fundamental
safety precautions be respected:
a
Do not allow children or infirm persons to operate the
system unsupervised.
a
It is forbidden to use electrical devices or equipment,
such as switches, appliances, etc. if there is a smell
of gas or un-burnt products. If so:
- Ventilate the room, opening doors and windows
- Close the fuel shut-off cock
- Report the fault immediately to the B's Technical
Assistance Centre or a professionally qualified heat-
ing engineer.
a
Do not touch the boiler while barefoot or wet.
a
Never clean or service the boiler without first discon-
necting it from the mains electricity supply by turning
the main power switch and the control panel switch
OFF.
a
Do not tamper with or adjust the safety or control de-
vices without prior authorisation and instructions from
the manufacturer.
a
Never pull, disconnect, or twist the electrical cables
coming from the appliance even if it is disconnected
from the mains electricity supply.
a
Do not obstruct or restrict the vents in the room where
the boiler is installed. Adequate ventilation is essen-
tial for correct combustion.
a
It is prohibited to leave inflammable substances and
containers in the room where the modular condens-
ing system is installed.
a
Do not dispose of packaging material into the envi-
ronment, or leave it within the reach of children, since
it can become a potential hazard. Dispose of packag-
ing material in compliance with applicable legislation.

1.3 Description of the appliance
The Power Plus Box SE system is a module to be combined
with a Power Plus Box system (SLAVE) for implementing a
heating plant in only two cabinets, with powers of 250 and
300 kW, respectively. The module includes the kit complete
with the I.S.P.E.S.L. components and the hydraulic separa-
tor that also acts as a distribution component on two sepa-
rate circuits (high temperature and low temperature).
The I.S.P.E.S.L control and safety components foreseen by
collection R, for this type of application, are positioned on
the delivery manifold, downstream of the last combustion
unit.
The technical manual for the
Power Plus Box system de-
scribes the safety devices and the relative references to
the provisions of collection R of I.S.P.E.S.L. and the relative
declaration.
Power Plus Box 100 SE
Module consisting of 2 heat generators for heating and
domestic hot water production systems, complete with
I.S.P.E.S.L. components and the hydraulic separator.
Heat input from 14.4 to 76.7 kW .

1.4 Safety devices
The Power Plus Box SE modular system is equipped with
the following safety devices, installed on every heating el-
ement:
Safety thermostat with automatic reset, which, when tripped
at 90°, shuts off the burner.
Hydraulic circuit diagnostics the minimum flow rate of the
carrier fluid for every heating element is controlled by a
differential water pressure switch and an electronic safety
system that controls a delivery sensor and a return sensor.
The equipment is protected if there is no water or in the
case of insufficient circulation.
Safety valve for the heating system pressure, which trips,
draining the system if circuit pressure exceeds the limit (5.4
bar).
Maximum pressure switch (ISPESL type-approved).
Flue gas evacuation safety the flue gas sensor, located at
the bottom of the exchanger, provokes a fault in the case
of high flue gas temperature (> 80°C). Furthermore, the
"check valve" present in the flue gas exhaust line prevents
the flue gas from passing between heating elements.
Fan safety the fan speed is always monitored by a Hall-ef-
fect speed indicator device.
The Power Plus Box SE modulating systems are prepared
for cascade-coupling and this makes it possible to imple-
ment compact and extremely flexible central heating plants
thanks to the system's modulating ratio.
b
The tripping of the safety devices indicates a poten-
tially hazardous malfunction of the modular system,
therefore contact Technical Assistance Centre imme-
diately.
Therefore it is possible to restart the system after waiting a
brief period (see the first start-up chapter).
a
The modular system must not be operated, even tem-
porarily, if the safety devices are not functioning or
have been tampered with.
b
The safety devices must be replaced by Technical
Assistance Centre, only using original components
from the manufacturer. Refer to the spare parts cata-
logue provided with the modular system.
After making the repair, correct that the modular system is
operating properly.

It is applied on the front part of the device and indicates the type of gas used by the modular system and the coun-
try of destination.
2 Technical data plate
It indicates the technical and performance data.
3 Serial number plate
This is located on the boiler body and specifies the serial number, model, and furnace power.

Spare parts and/or technical operation require the exact identication of the corresponding model. The absence of,
tampering with or removing the identication plates or other does not make it possible to reliably identify the product,
makes any installation and maintenance operation difcult and invalidates the warranty.
