INSTALLATION 1.2
BOILER ROOM 1.2.1
The boiler must be installed in a fixed loca-
tion, by qualified engineers in compliance
with all the instructions in this manual . The
boiler must be positioned on non combustible
material able to withstand the weight of the
boiler when filled. Furthermore the installa-
tion must comply with current standards and
regulations.
The boiler should be installed as a class B
device( open flued). Purpose made ventila-
tion must be provided and comply with the
following:
– 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
2
. The section can
also be calculated, using the following
ratio:
Q
S =
100
where “S” is expressed in cm
2
.
“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 exhaust
discharge.
CONNECTION OF THE FLUE 1.2.2
A flue should correspond to the following
requirements:
– It should be of waterproof material and
resistant to temperature of the exhaust and
related condensations.
– It should be of a sufficient mechanical
resistance and a low thermal conductivity.
– It should be ideally be twin walled and
sealed in order to avoid cooling of the
flue.
– It route should be as vertical as is pos-
sible and the terminal part should have a
static aspirator, which assures an efficient
and constant discharge of the combustion
product.
– The flue terminal should be located in a
position free from down draughts, at least
1 metre above the point of exit through
the roof or 600mm above the apex of then
roof- see fig 2a
– The flue diameter should not be less than
the diameter of 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 obtained
from the following ratio:
P
S = K
√ H
S section resulting in cm
2
K reduction coefficient:
– 0,045 for wood
– 0,030 for carbon
P boiler capacity in kcal/h
H height of the chimney in meters
measured from the flame axis at the
exhaust of the chimney in the atmos-
phere. For the dimensioning of the
flue you should consider the effec-
tive height of the chimney in meters,
measured from the flame axis at the
top, diminished with:
– 0,50 m for each direction chang-
ing of the connection tube between
boiler and flue;
– 1,00 m for each horizontal devel-
opment meter of the connection
itself.
CONNECTION OF THE PLANT 1.2.3
The connections to the boiler must be acces-
sible. Isolation valves MUST NOT be fitted.
Drain points must be included.
Plastic piping should not be used.
CAUTION: It is obligatory to include 3 bar
safety valves on the system not included
in supply.
Plant filling
The heating system should be flushed and
cleaned prior to connection of the boiler.
The final filling should be done slowly to
allow any air to escape.
The cold loading pressure of the plant should
