1.1.8. HYDRAULIC CONNECTION
DANGER
Make sure that the tubes of the water
and heating plant are not used as grounding
system for the electrical plant. There are not
suitable for such use.
WARNING
To prevent voiding the warranty and to
ensure the proper operation of the boiler, please
wash the plant (if possible when hot) with suitable
pickling or descaling solutions in order to remove
the impurities coming from tubes and radiators.
WARNING
When connecting the equipment
to water supply, avoid excessive bending and
recovery operations from any off axis positioning
that may damage the tubes causing leaks,
malfunction or early wear.
WARNING
In order to avoid any vibrations and
noises, do not use tubes with small diameters or
elbows with small radius and significant cut-off
of the passage sections.
WARNING
Connect the outlets of safety valves,
three-ways valves (if present) and of the cylinder
(if present) to an outlet funnel, to prevent the
boiler room from flooding if these devices cut
in. This outlet should preferably be sent to the
outside so as to avoid damage to persons or
property caused by hot water in the event that
the valve should open. The manufacturer is not
responsible for any flooding due to the opening of
the safety valve in case of system overpressure.
WARNING
On systems with a closed expansion
tank, the pressure reducer on the automatic
supply unit (where available) should be set to a
pressure that will not exceed the initial design
setting. Make sure that while the equipment is
working the system pressure does not exceed the
working pressure for each component.
WARNING
Ensure that, during the boiler
operation, the system pressure doesn’t exceed
the working pressure of each component.
WARNING
In order to prevent scales or deposits
on the primary heat exchanger, the heating/D.H.W
circuit inlet water must be treated according to
the current regulations.
It is however suggested to treat the water:
› for the heating circuit, over 25 French degrees,
by means of chemical conditioning treatment
for powers < 100 kW or sweetening for powers
> 100 kW.
› for the D.H.W, over 15 French degrees, by means
of chemical conditioning treatment for powers
< 100 kW or sweetening for powers > 100 kW.
It is also necessary to install a safety filter to
protect the system.
WARNING
In case the boiler is installed as part of
a low temperature circuit, please install a safety
thermostat on the heating flow, which can stop
the boiler activity in case of high heating flow
temperature. The company assumes no
liability for damage caused to persons or for failure
to comply with these instructions.

1.1.9. CHARACTERISTICS OF THE
WATER OF THE SYSTEM
For a correct operation of the system, it is
necessary to make sure that:
1. The system does not present losses or that the
most obvious are at least eliminated;
2. If an automatic filling system is present, a litre
meter must be installed in order to precisely know
the extent of any losses;
3. The filling in of the system and the top ups are
performed with softened water in order to reduce
the total hardness. The water must also be treated
in order to maintain the pH within the provided
threshold so as to avoid corrosion phenomena.
4. Either on new systems or on replacements, the
system must be fitted with efficient systems which
ensure the elimination of the air and impurities:
Y filters, micro impurity separators and micro
bubbles of air separators;
5. Avoid draining the water of the system during the
routine maintenance even if it is about apparently
insignificant quantities: for example, in order to
clean the filters, provide the system with adequate
shut-off valves;
6. Always perform an analysis of the water of
the system before opening the communication
between the new generator and the system, in
order to establish if the parameters present in the
water indicate the need to fully drain the system,
to use the water already present in the system or
to chemically wash the system using utility water
adding a detergent when it is suspected that the
system might be dirty or particularly clogged and
at the next loading with new treated water.
Water treatment
In order to preserve the integrity of the water-
fume exchanger and to guarantee optimal thermal
exchanges, it is necessary that the water of the
primary circuit, circulating inside the exchanger
of the condensate boiler, has the characteristics
defined and constant in time. To obtain this, it
is fundamental to perform a series of system
preparation and maintenance operations such as:
• washing the system;
• check the characteristics of the water of the
system;
The type of treatment to be performed will be
chosen based on the characteristics of the water
to treat, of the type of system and on the requested
purity limits
Oxygen
A certain amount of oxygen always enters the
system, both during the filling phase and during
the use in case of reintegration or presence of
hydraulic components without oxygen barriers.
The reaction between the oxygen and the stainless
steel creates corrosion and forms sludge. While
the water fume exchanger is made of stainless
steel, and therefore it is not subject to corrosion,
the sludge created in the carbon steel system
is deposited in the warm points, including the
exchanger. This has the effect to reduce the heat
capacity and thermally insulate the active parts of
the exchanger, which might cause damages.
The precautions to limit the phenomena are:
- Mechanical systems: a deaerator combined with
a sludge remover, correctly installed, reduce the
quantity of oxygen circulating inside the system.
- Chemical systems: the additives allow the oxygen
to dissolve in water.

Hardness
The filling and make-up water hardness brings
a certain amount of limestone into the system.
It attacks the warm parts of the exchanger, thus
creating load losses and thermal insulation losses
on the active parts. This phenomena can cause
damages.
The filling and make-up water of the system, if
it does not fall under the values indicated below,
should be softened. Moreover, additives can be
added in order to maintain the limestone into
the solution. The hardness must be periodically
checked and registered.
Acidity 7 < pH < 8.5
Conductivity < 400 μs/cm (at 25°C)
Chlorides < 125 mg/l
Iron < 0.5 mg/l
Copper < 0.1 mg/l
If the above indicated limits are exceeded, a water
must be chemically treated.
The type of treatment to be performed will be
chosen based on the characteristics of the water
to treat, of the type of system and on the requested
purity limits.

1.1.10. SYSTEM FILLING
WARNING
For system filling use only clean tap
water. In order to prevent limestone build-up and
damages to the domestic water heat exchanger,
the hardness of the domestic supply water
should not exceed 15° Fr. However, please check
the characteristics of the water used and install
suitable treating devices.
WARNING
If the system is filled by adding ethylene
glycol-type chemical agents you have to install on
the loading system a hydraulic trip unit in order
to separate the heating circuit from the domestic
circuit.
Before powering up the boiler, fill the system as
follows:
1. slightly loosen the cap of the jolly valve placed
on the top of the condensing block to release
the air form the top of the system (1-fig.1);
2. check that the jolly valves vent the air present
in the system are not blocked;
3. connect a rubber pipe to the draining tap placed
on top of the condensing heat exchanger (2-
fig.1);
4. open the general domestic water input tap and
load the system by exhaling all the air;
5. use pressure gauge present in the system to
make sure that the system pressure reaches
the design value;
6. after performing this operation, make sure
that the loading tap is properly closed.
7. Open the air relief valves of the radiators and
check the air removal process. When the
water starts to leak close the radiators air
relief valves.
8. If after performing these operations you
observe a decrease of the water pressure
inside the system, open once again the loading
tap until the pressure gauge reaches the
design pressure.

1.1.11. CONDENSATE DRAIN
FILLING THE CONDENSATE DRAIN SIPHON
Before starting the boiler you have to fill the
condensate collection siphon in order to avoid fuel
reflux through the siphon.
Fill the condensate collection siphon as follows:
› Unscrew the screw “P” (fig. 1), extract the siphon
and fill it with water up to the highest point “T”
(fig. 1);
› Connect the adequately prepared flexible
condensate drain tube to a disposal system
(it is necessary to neutralise the condensate
if the material out of which the canal system
where the condensate arrives is composed
presents a corrosion risk; please see
paragraph ‘CONDENSATE NEUTRALISER’).
The condensate can be drained directly in
the sewerage system by inserting an easily
serviceable siphon.
WARNING
After the first months of operation of the
device, it is recommended to clean the condensate
collection siphon from any deposits deriving
from the first transit of the condensate inside the
technical components of the boiler. Such deposits
might cause a malfunction of the siphon.
CONDENSATE DRAIN
The heat generator produces a significant quantity
of condensate during operation. This condensate
has an acid pH of 3-5. Observe the national standard
in force and the local regulations for the disposal
of the condensate produced by the generator.
The designer, according to the power of the system
and the intended use of the building, is bound to
evaluate the acceptance of systems in order to
neutralise the acid condensate.
The system must be performed so as to avoid the
freezing of the condensate. Before putting into
operation the device, check the correct evacuation
of the condensate.
WARNING
Before connecting the condensate
collection siphon to the drain tube, check that the
slope of the boiler is ensured according to the
indications from chapter ‘INSTALLATION OF THE
GENERATOR’.
WARNING
Correctly connect the condensate
collection siphon of the boiler to a draining system
by adding the slope to the drain of the condensate
of the fume exhaust duct. Where possible, it is
recommended to perform such connection by
means of a collection glass in order to check
the correct discharge of the condensate avoiding
stagnations that might cause dangerous returns of
the condensate to the boiler.
In order to connect the condensate draining to
the draining system, use only corrosion-resistant
materials with an adequate diameter.

INSTALLER
CONDENSATE NEUTRALISER
Assemble the condensate neutralisation box, fitted
with granulate and active carbons for a treated
power up to 350 kW (see fig.2). The device allows
neutralising the condensate which is collected
inside the thermal generators and/or in the fume
discharge systems made of stainless steel, plastic,
glass or ceramic.
The acid condensate, inserted into the
neutralisation box, follows a mandatory path for
two phases; the first one, filtration of nitrates and
sulphates by means of active carbons contained
in the first tube line, in the second one, the pH is
increased.
The acidity of the condensate can be checked
by using litmus paper in order to determine the
pH. Then, the neutralised condensate can be
transported into the sewage system.
MAINTENANCE
The pH parameters must be comprised between
< 7 and 8.5 >.
Every six months, it is necessary to establish the
PH of the treated condensate inside the neutraliser.
Immerse a litmus paper (or a suitable digital
tool) in the condensate near the tapped draining
connection for about 2 seconds and thus lay it on a
white paper. After about 30 seconds, it is possible
to compare with the coloured scale. The neutral
point is on the value 6.8-7; at a lower value, the
condensate is acid, at a higher value, it is base].
If necessary, replace the active carbon and the
reagent granulate.
