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.

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.
