Installation - Chappee EDENA EVOLUTION EF 1.22 Installation Instructions Manual

INSTALLATION

The boiler should be installed in a fixed
location and shall be carried out only by
specialized and qualified firms in com-
pliance with all instructions contained
in this manual.
2. 1 BOILER ROOM
AND VENTILATION
There are no particular regulations to
follow with reference to the boiler
room because EDENA EVOLUTION EF
1.22-1.31 boilers, which do not exceed
the 35 kW limit, can be installed in
rooms that are sufficiently ventilated.
The rooms where the gas-fired
systems are installed must receive at
least the quantity of air necessary for
the normal combustion of the gas used
by the various installations.
Therefore, to ensure the air circulation
in the rooms, it is necessary to make
some holes in the walls.
These holes must have the following
characteristics:
– Have e total free surface of mini-
mum 6 cm 2 for each kW of thermal
capacity, for a minimum of 100 cm
– They must be located as close as
possible to floor level, not prone to
obstruction and protected by a
grid which does not reduce the
effective section required for the
passage of air.
The EDENA EVOLUTION
1.39÷1.61 models with a capacity
exceeding 35 kW shall instead be
installed in a boiler room that meets
the existing safety regulations for
network gas-fired heating systems,
where minimum distances must be
observed.
2.2 BOILER CONNECTION
To protect the heat system from
damaging corrosion, incrustation or
deposits, after installation it is extre-
mely important to clean the system
using suitable products such as, for
example, Sentinel X300 or X400.
Complete instructions are provided
with the products but, for fur ther
information, please contact the manu-
facturer. For long-term protection
agains corrosion and deposits, the use
of inhibitors such as Sentinel X100 is
recommended af ter cleaning the
system. It is important to check the
concentration of the inhibitor after
each system modification and during
maintenance following the manufactu-
rer's instructions (specific tests are
available at your dealer). The safety
valve drain must be connected to a
collection funnel to collect any dischar-
ge during interventions.
WARNING: Failure to clean the heat
system or add an adequate inhibitor
invalidates the device's warranty.
Gas connections must be made in
accordance with current standards
and regulations. When dimensioning
gas pipes fr om the met er t o the
module, both capacity volume (con-
sumption) in m /h and gas density
3
must be taken into account.
The sections of the piping making up
the system must be such as to gua-
rantee a supply of gas sufficient to
cover the maximum demand, limiting
pressure loss between the gas meter
and any apparatus being used to not
greater than:
– 1.0 mbar for family II gases (natural
gas);
– 2.0 mbar for family III gases (butane
or propane).
A sticker inside the module includes
2 . identification and gas type data speci-
fic to the module.
2.2. 1 Filter on the gas pipe
The gas valve is supplied ex factory
with an inlet filter, which, however, is
EF not adequate to entrap all the impuri-
ties in the gas or in gas main pipes.
To prevent malfunctioning of the valve,
or in certain cases even to cut out the
safety device with which the valve is
equipped, install an adequate filter on
the gas pipe.
2.3 FLUE
A flue for the discharge into the atmo-
sphere of the products of combustion
of natural draught plants must have
the following characteristics:
– be sealed against the products of
combustion, waterproof and insu-
lated;
– be made of materials capable of
withstanding normal mechanical
stresses, heat and the action of the
products of combustion and their
condensate;
– be vertical and with no narrowing
throughout its whole length;
– be properly insulated to avoid flue
gases condensing or cooling, espe-
cially if it is placed outside a building
or in rooms with no heating;
– be kept at a safe distance from com-
bustible and easily inflammable
materials by an air space or any
other suitable insulating material;
– have a chamber collecting solid
materials and condensates below
the mouth of the first flue;
chamber must be at least 500 mm
high. Access to this chamber must
be ensured through a hole with an
airtight metal door;
– its inner section must be round, squa-
re or rectangular; if it is square of
rectangular, the corners must be
round and have a radius of 20 mm
minimum; however, hydraulically equi-
valent sections are also permitted;
– be topped by a chimneypot having its
outlet outside the reflux area in
order to avoid back pressures which
may obstruct the free discharge of
flue gas into the air;
– there must be no mechanical suc-
tion equipment at the top of the pipe;
– there must be no overpressure in
stacks placed inside or adjacent to
inhabited rooms.
