3 TECHNICAL FEATURES
3 .1 Main features
Power Plus Box P INT-EXT
is a condensing, modular, pre-
mixed, blown, thermal group; it is made up of a series of
Power Plus Box P INT-EXT
thermal elements installed in bat-
tery.
A unit is made of N° 2, 3 or 4 heat exchangers, each with
a modulating power from 23 ti 115 kW; equipped with cli-
matic regulation and RS485 connection. Each device can
be serially matched up with same tipe units up to a total
installed power of 3680 kW (eight

equal to a total of di 32 heat exchangers).

In case of installation of more than 32 unit (up to 60
unit) please contact

tre.
It is possible to connect up two thermal groups (with a total
of 8 heat exchangers) directly using the internal 5” hydrau-
lic manifolds and the internal 3” gas manifold.
The efficiency of the generators reaches 109% based on
the lower heat potential of natural gas (Hi) making it possi-
ble to use a flue manifold entirely made of plastic (PP). The
system also enables continual modulation of the gas and
combustion air flow.
The Power Plus Box P INT-EXT heating unit is the optimum
as far as operating costs (up to 109% efficiency per Hi, see
Figure 1) reliability and flexibility. In fact, thanks to the new
heat exchanger with improved power, to the new electronic
management, to the modularity and versatility, it is possible
to make a rapid connection to any kind of heating system
and storage hot water production.
Figure 1
The insertion of a single thermal element in cascade, over
the traditional rotation of the ignition, can take place with
variable factor of heating power load
, so that when a cer-
tain power percentage of the first element is reached (e.g.
30%), the successive element already starts with the same
load factor. This latter feature allows to share the power
supplied inside more than one heat exchangers with a
power/exchange surface ratio which is particularly favour-
able for condensation latent heat.
a
Children and people with disabilities or without expe-
rience and specific knowledge are forbidden to use
the heating unit unless they are assisted by a qual-
ified person responsible for their safety.It is forbid-
den 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 gas valve at the mains;
- immediately call in the Technical Assistance Centre
or professionally qualified personnel.
a
It is forbidden to touch the heating unit with bare feet
or parts of the body wet.
a
It is forbidden to start on any technical or cleaning
jobs before disconnecting the heating unit from the
power mains.
a
It is forbidden to alter the safety and adjustment de-
vices without permission and instructions from the
heating unit manufacturer.
a
It is forbidden to obstruct the condensate drain.
a
It is forbidden to pull, detach, twist the wiring coming
out of the heating unit, even if unplugged from the
power supply.
a
It is forbidden to obstruct or reduce the size of air
vents.
a
It is forbidden to expose the boiler to atmospheric
agents (if it is not a specific unit for outdoors).
a
It is forbidden to leave containers or flammable sub-
stances in the premises where the boiler 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
The user is forbidden to open the cupboard contain-
ing the heating unit. Any jobs on the inside of the lat-
ter must be done by the Technical Assistance Centre
or by qualified personnel.
a
It is forbidden to discard the product as household
waste. At the end of its service life, it can be con-
signed to specific selected waste centres provided
by the local authorities or else to dealers providing
this service. Disposing of a domestic appliance sep-
arately will prevent possible harmful consequences
for environment and health derived from inappropri-
ate disposal, likewise making it possible to recuper-
ate the materials it is made of with substantial savings
in energy and resources.
