2 INSTALLATION
2.1
BOILER ROOM
Check that the room has the requirements
and features in accordance to the rules in
force. Furthermore, the room should be
aired, in order to have a regular combu-
stion. Therefore it is necessary to practice
some openings in the walls of the room,
which correspond to the following requi-
rements:
– They should have a free section of at
least 6 cm
2
for each 1,163 kW (1000
kcal/h). The minimum opening section
shouldn't be smaller than 100 cm
section can also be calculated, using the
following ratio:
Q
S =
100
2
where "S" is expressed in cm
"Q" is expressed in kcal/h
– The opening should be situated on the
lower part of an outer wall, preferably on
the opposite of the one for the combu-
stion gas discharge.
2.2
CONNECTION TO THE FLUE
A flue should correspond to the following
requirements:
– It should be of waterproof material and
resistant to temperature of smokes and
related condensations.
– It should be of a sufficient mechanical
resistance and a weak thermal conduc-
tivity.
– It should be perfectly hermetic in order
to avoid cooling of the flue.
– It should have the most possible vertical
process and the terminal part should
have a static aspirator, which assures an
efficient and constant discharge of the
combustion product.
– In order to avoid the wind creating a very
high pressure around the chimneypot, so
that it prevails on the ascensional force
of the combustion gas, it is necessary
that the discharge orifice hangs over at
least 0,4 meters of whatever structure
adjacent the chimney itself (including the
roof ridge) of at least 8 meters.
– The flue shouldn't have a diameter in-
ferior to the boiler connection; for flues
with square or rectangular sections, the
internal section should be higher than
10% compared to the boiler connection
one.
– The net section of the flue can be obtai-
ned from the following ratio:
P
S = K
√H
2
S section resulting in cm
K reduction coefficient:
– 0,045 for wood
– 0,030 for carbon

H height of the chimney in meters me-
asured from the flame axis at the
exhaust of the chimney in the atmo-
sphere. For the dimensioning of the
flue you should consider the effecti-
ve height of the chimney in meters,
measured from the flame axis at the
top, diminished with:
– 0,50 m for each direction chan-
ging of the connection tube
between boiler and flue;
– 1,00 m for each horizontal deve-
lopment meter of the connection

itself.

CONNECTION OF THE PLANT
The connections should be easily discon-
nected by means of pipelines with revolving
.
joints. It is always advisable to assemble
suitable interception shutters on the piping
of the heating installation.
CAUTION: It is obligatory to assemble sa-
fety valves on the system not included in
supply.
2.3.1
Plant filling
Before starting with the connection of the
boiler it is advisable to let the water cir-
culate in the piping, in order to elimina-
te possible foreign bodies, which could
compromise the correct operation of the
appliance.
The filling should be carried out slowly
in order to make the air bubbles go out
through the proper outlets, placed on the
heating installation.
The cold loading pressure of the plant and
the pre-blowing pressure of the expan-
sion tank, should correspond or howe-
ver shouldn't be inferior to the height
of the static column of the plant in case
of closed circuit heating installations (for
example, for a static column of 5 meters,
the pre-loading pressure of the tank and
the loading pressure of the plant should
correspond at least to a minimum value
of 0,5 bar).
2.3.2
Features of the feed water
THE TREATMENT OF THE WATER USED
FOR THE HEATING INSTALLATION
IS ABSOLUTELY NECESSARY IN THE
FOLLOWING CASES:
– Very vast plants (with high water con-
tents).
– Frequent replenishment water inlets in
the plant.
– If the partial or total emptying of the
plant should be necessary.
2.4
BRAZIER GRID ASSEMBLY
(optional)
In order to carry out the assembly proceed
in the following way (fig. 3):
– Punch the card of the outer part, betwe-
en the front head and the intermediate
element, using a bit of 10 ø as indicated
in the detail (B).
– Place the back grid (12) in the combu-
stion chamber.
– Place the front grid (10) and block it to
the hub (9) with the screws (8) and the
nuts (7); block the front grid from the
right side of the boiler body with the
screws (5).
– Hook the tie rod (6) to the seats extracted
from the front and rear grid.
