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 combustion.
Therefore it is necessary to practice some
openings in the walls of the room, which cor-
respond to the following requirements:
– They should have a free section of at
least 6 cm
for each 1, 1 63 kW (1000
2
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
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 resi-
stance and a weak thermal conductivity.
– 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 neces-
sary 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 infe-
rior to the boiler connection; for flues with
square or rectangular sections, the inter-
nal 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:

S = K

height of the chimney in meters
measured 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 t he 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 disconnec-
ted by means of pipelines with revolving
joints. It is always advisable to assemble sui-
2
.
table interception shutters on the piping of
the heating installation.
CAUTION: It is obligatory to assemble
safety 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 circula-
te in the piping, in order to eliminate possi-
ble 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 throu-
gh the proper outlets, placed on the heating
installation.
The cold loading pressure of the plant and
the pre-blowing pressure of the expansion
tank, should correspond or however
shouldn't be inferior to the height of the sta-
tic column of the plant in case of closed cir-
cuit heating installations (for example, for a
static column of 5 meters, the pre-loading
pressure of the tank and the loading pres-
sure 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 ABSO-
LUTELY 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,
between the front head and the interme-
diate element, using a bit of 10 ø as indi-
cated 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 extrac-
ted from the front and rear grid.
– Place the intermediate grids (11).
– Introduce the ring (4) and the lever (3) on
the hub (9), fixing then everything with
the washer (2) and the screw (1).
