1 GENERAL INFORMATION
1.1 General Safety Information
b
After removing the packaging, check the condition and com-
pleteness 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
instruction 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 Bor pro-
fessionally qualied personnel.
b
Periodically check that operating pressure in the water circuit
is over 1 bar but below the maximum limit specied for the boil-
er. If this is not the case, contact Technical Assistance Centre
B or a professionally qualied heating engineer.
b
The following operations shall be necessary if the thermal mod-
ule 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 thermal module 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
thermal module, even when it is passed on to another owner
or user or transferred to another installation. If it is lost or dam-
aged, please contact your local Technical Assistance Centre
Bfor a new copy.
b
This manual must be read carefully so as to ensure the correct
and safe installation, operation and maintenance of the appli-
ance. The Owner must be adequately 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 Protection function, it can be exposed to tem-
peratures ranging from -20°C to 40° C
b
Regularly check that the condensate drain is free from obstruc-
tion.
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 Assis-
tance Centre or a professionally qualied heating engineer.
a
Do not touch the boiler while barefoot or wet.
a
Any technical or cleaning activity is forbidden before discon-
necting the appliance from the main power supply by switch-
ing 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 devices with-
out 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 essential for correct com-
bustion.
a
Do not expose the appliance to weather elements (without us-
ing the dedicated accessory). It has been designed for indoor
use.
a
Do not switch off the appliance if the outdoor temperature 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 environment, or
leave it within the reach of children, since it can become a po-
tential hazard. Dispose of packaging 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 al-
lowed not remove the thermal module's casing.

1.3 Description of the appliance
POWER MAX it is a condensing, pre-mixed thermal module consist-
ing in a modulating thermal element.
It is available in various models, ranging from 34,9kW to 131kW.
Optimal combustion management supports high yields (over 109%,
calculated over NVC, in condensation regime) and low polluting
emissions (Class 6 pursuant to EN 15502).
The thermal module is designed for open chamber operation, but
can be converted to sealed chamber operation by tting a dedicated
accessory.
The appliance in standard conguration is envisaged for indoor in-
stallation to guarantee an IPX4D protection level.
b
POWER MAX appliances may be cascaded to reach a maxi-
mum power of 1.12 MW.
The appliance's key technical features are
- pre-mix burner with constant air-gas ratio;
- helical type heat-exchanger, coil with smooth stainless steel
tube (single coil for models POWER MAX 50 P DEP - POWER
MAX 50 P, double coil for models POWER MAX 65 P ÷ POWER
MAX 150), to guarantee a good corrosion resistance and the
possibility of working with high Δt (up to 40°C) reducing the
time of set-up;
- power from 34,9 to 131 kW;
- maximum ue gas output temperature 100°C;
- microprocessor management and control with self-diagnos-
tics, shown by means of a display, and logging of main errors;
- Anti-Frost function;
- provision for room thermostat / heat request on high or low tem-
perature zones;
- option to manage a CH circuit and a DHW circuit with storage
tank;
- high-efciency and high residual discharge head circulator
(for models up to 68kW; a circulator is available as an acces-
sory upon request for other models);
- climate control function (available only when using the outdoor
temperature sensor accessory).
1.4 Safety devices
All appliance functions are electronically controlled by a dual proces-
sor technology board approved for safety functions.
Any malfunction results in the appliance being shut down and the
automatic closure of the gas valve.
The following is installed on the water circuit:
-
Safety thermostat .
- Flow sensor capable of monitoring the main circuit's ow on
an ongoing basis and of stopping the appliance in the event
of insufcient ow.
- Temperature probes on delivery and return lines that meas-
ure the temperature difference (∆t) between input and output
uid and enable activation of the control.
- Minimum pressure switch .
The following is installed on the combustion circuit:
- Gas solenoid in class B+C , with pneumatic gas ow com-
pensation depending on the suction line's air ow rate.
- Ignition/detection electrode .
- Flue gases temperature probe .
b
The triggering of safety devices indicates the malfunction of
a potentially hazardous thermal module. Therefore, contact
Technical Assistance Centre immediately. 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 Assistance
Centre, using only original parts. Refer to the spare parts cat-
alogue 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 temporarily,
when tampered safety devices are not in operation or have
been tampered with.
