Power Plus Box P INT-EXT
thermal modules are made up of
2, 3 or 4 thermal elements which are common to all the boil-
ers belonging to the same family and they have a thermal
power of 115 kW (Hi).
The modules can be installed in cascade according to the
power required by the installation and they can reach a
maximum of 32 thermal elements. The grouping of more
than one module allows to make some noiseless thermal
plants, with low thermal inertia and high power in a very
simple and rational way. Each thermal module is equipped
with the following connections which have been pre-set for
the connection to the system (see table).

4 .4 System cleaning and water
treatment
This preventive measure is absolutely required whenever a
heat generator needs to be replaced in but it is in any case
recommended also on new systems, in order to remove
any waste, dirt, working residues, etc.
To clean the system, if the old generator is still present in
the system:
- add a descaling additive to the system water (contact
the
B
Technical Assistance Centre);
- Have the system operate with the generator ON for
approximately 7 days;
- Discharge the system’s dirty water and wash the sys-
tem once or several times using clean water.
If the system is very dirty, repeat the last procedure one
more time.
If the old generator is not present or available, use a pump
to circulate the water + additive through the system for
about 10 days and perform a final washing as described in
the previous paragraph.
At the end of cleaning operations, before installing boiler

, it is advisable to add protection)
to the system water (contact the

tance Centre);

for flushing out the water circuit inside the exchanger.
Do not use incompatible liquid detergents, including
acids (e.g. hydrochloric acid and similar acids) at any
whatsoever concentration.
4 .5 Positioning and preparation for
installation
Follow the procedure below to install the thermal groups:
1 After unpacking the boiler/s, establish the output direc-
tion of the water, gas and condensate pipes (e.g.: left
or right connection). Also establish the modality and the
position of both the flue manifold and the eventual air
manifold (in case of installation with outside air intake).
It is recommended to take into account the electric con-
nections (230 V supply) of the thermal group too (see
paragraph 6.2).
Please note that each pipes connection to the system can
be indifferently made at the right of left side of the thermal
group.
However, it is suggested to follow one of the schemes of
installation reported on this manual (see chapter 5).
2
Place the thermal group/s near the inlet and outlet pipes
of the system.
The groups can be installed either with
right or left outlet of water, air, smokes, condensate, gas
pipes (e.g.: air inlet on the right, water outlet on the left,
gas on the right).
The position of each
Power Plus Box P INT-EXT
inside
the area of installation can vary according to specific
requirements of space or to the type of the installation
itself (e.g.: leaned against the wall, back-to-back, etc.);
in any case, make sure that same necessary space
is left for the passage of the electric supply cables of
each Power Plus Box P INT-EXT and to let the front panel
open. Space is also required in case of maintenance
services of the flue, condensate, and gas pipes.
3 1. Mount the side panels of the
Power Plus Box P INT-
EXT
and connect the first (or the only) thermal group of
the battery to the system, use the correct connections
and carefully avoid any sudden variation of section
among the piping of both the boilers and the system.
If necessary, adjust the boiler’s feet height to level the
frame of the boiler and to open the doors easily.
4 2. Once water connections between the first group
and the system have been made, connect successively
the other eventual thermal groups to the first one, fol-
lowing the advice above. Use sections male/male Ø 50
mm of about 13 cm lengths to connect the different con-
densate discharges.
