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 qualied
heating engineer. On completion of the installation,
the installer must issue the owner with a declaration
of conformity conrming 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 specied 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 event of a water leak, disconnect the thermal
module from the main power supply, shut off the water
supply and promptly notify the Technical Assistance
Centre B or professionally qualied personnel.
b
Regularly check that the condensate drain is free
from obstruction.
b
Periodically check that operating pressure in the wa-
ter circuit is over 1 bar but below the maximum limit
specied for the boiler. If this is not the case, contact
Technical Assistance Centre Bor a professional-
ly qualied heating engineer.
b
The following operations shall be necessary if the
Modular 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 sys-
tem at least once a year.
b
This manual is an integral part of the appliance and
must therefore be kept with care and must ALWAYS
accompany the Modular system, even when it is
passed on to another owner or user or transferred to
another installation. If it is lost or damaged, please
contact your local Technical Assistance Centre B
for a new copy.
b
This manual must be read carefully so as to ensure
the correct and safe installation, operation and main-
tenance of the appliance. The Owner must be ade-
quately informed and trained on how to operate the
appliance. Make sure that he/she is familiar with all
the information required for safe system operation.
b
The thermal module, before being connected to the
hydraulic system, the gas network, and the electrical
system, may be exposed to temperatures ranging
from 4°C to 40°C. After it can activate the Frost Pro-
tection function, it can be exposed to temperatures
ranging from -20°C to 40° C
b
Regularly check that the condensate drain is free
from obstruction.
b
We recommend cleaning inside the exchanger once
a year, extracting jet and burner and removing any
installation debris by suction. This operation should
be done by personnel from the Technical Assistance
Centre only.
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 inrm 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 qualied heat-
ing engineer.
a
Do not touch the boiler while barefoot or wet.
a
Any technical or cleaning activity is forbidden before
disconnecting the appliance from the main power
supply by switching the system's master switch and
the appliance's main switch to the "OFF" position.
a
Do not tamper with or adjust the safety or control de-
vices without prior authorisation and instructions from
the manufacturer.
a
Do not plug or block the condensate drain outlet.
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
Do not expose the appliance to weather elements
(without using the dedicated accessory). It has been
designed for indoor use.
a
Do not switch off the appliance if the outdoor temper-
ature may drop to below ZERO (frost hazard).
a
Do not leave ammable containers and substances
in the room where the device 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.
a
Do not activate the thermal module without water.
a
Individuals without specic qualications and skills
are not allowed not remove the thermal module's
casing.

1.3 Description of the appliance
Power Max BOX is a modular, premixed condensing sys-
tem, consisting of a cascade of modulating thermal ele-
ments installed inside a frame assembled in anodised alu-
minum and painted panels.
The standard product is suitable for indoor installation, with
open chamber combustion; it can be transformed either
into sealed combustion or into indoor version by means
of some specic accessory kits that increase its electrical
protection up to IPX5D.
The cabinets are equipped with 2, 3 or 4 thermal elements
from 57 up to 131 kW, for a total power of 114 up to 524 kW
and are available in versions that have low-consumption
pumps ("P" versions) or 2-way valves ("V" versions).
The models with heat-exchanger from 131 kW (300-2 P/V -
450-3 P/V - 600-4 P/V) are suitable for cascade installation,
with side by side coupling, up to a maximum of 10 total
thermal elements and a power of 1310 kW.
The optimal management of combustion allows both high
efciency levels (exceeding also the 109%, value calcu-
lated on the PCI, under condensation) and low pollutant
emissions (Class 5 according to UNI EN 297).
The main technical features of the appliance are:
- pre-mix burner with constant air-gas ratio;
- helicoidal heat exchanger with double coil with
smooth stainless steel pipe, to guarantee good corro-
sion resistance and the option of operating with high
∆ts (up to 40°C), reducing system set-up times;
- power from 114 to 524 kW;
- maximum ue gas output temperature 100°C;
- microprocessor management and control with self-di-
agnostics, shown by means of a display, and logging
of main errors;
- Anti-Frost function;
- external probe that enables the climate control func-
tion;
- provision for room thermostat / heat request on high
or low temperature zones;
- option to manage a CH circuit and a DHW circuit with
storage tank;
- high efciency pump with high residual head mount-
ed on all "P" versions
1.4 Safety devices
All the functions of each thermal element are electronically
controlled by a board approved to perform safety functions
with dual processor technology.
Any malfunction results in the appliance being shut down
and the automatic closure of the gas valve.
On the water circuit of each thermal element are installed:
-
Safety thermostat .
- Flow sensor capable of monitoring the main circuit's
ow on an ongoing basis and of stopping the appli-
ance in the event of insufcient ow.
- Temperature probes on the ow and return that con-
tinuously measure the difference in temperature (∆t)
between inlet and outlet uid and allow the control to
intervene.
On the combustion circuit of each thermal element are in-
stalled:
- Gas solenoid in class B+C , with pneumatic gas ow
compensation depending on the suction line's air
ow rate.
- Ionisation electrode for detection .
- Flue gases temperature probe .
- The Minimum pressure switch is installed on the man-
ifold of the thermal module
b
The triggering of safety devices indicates the mal-
function of a potentially hazardous thermal module.
Therefore, contact Technical Assistance Centre im-
mediately. After a brief pause, it is possible to try and
restart the appliance (see Paragraph "Initial startup").
b
Safety devices must be replaced by Technical Assis-
tance Centre, using only original parts. Refer to the
spare parts catalogue supplied with the appliance.
After making the repair, check that the appliance is
working properly.
a
The appliance must not be put in service, even tem-
porarily, when tampered safety devices are not in op-
eration or have been tampered with.

Before loosening or removing the circulator cap, protect the electric devices located underneath from any water
that exits.
