2.1 BOILER ROOM
The boiler room should feature all
the characteristics required by stan-
dards governing liquid fuel heating
systems.
2.2
BOILER ROOM DIMENSIONS
Position the boiler body on the
foundation bed, which should be at
least 10 cm high. The body should
rest on a surface allowing shifting,
possibly by means of sheet metal.
Leave a clearance between the boi-
ler and the wall of at least 0.60 m,
and between the top of the casing
and the ceiling of 1 m (0.50 m in the
case of boilers with incorporated
D.H.W. tank). The ceiling height of
the boiler room should be less than
2.5 m.
2.3
CONNECTING UP SYSTEM
When connecting up the water sup-
ply to the boiler, make sure that
the specifications given in fig. 1 are
observed. All connecting unions
should be easy to disconnect by me-
ans of tightening rings. A closed ex-
pansion tank system must be used.
2.3.1 Filling the water system
Before connecting the boiler, tho-
roughly flush the system to elimi-
nate scale which could damage the
appliance.
Filling must be done slowly so as to
allow any air bubbles to be bled off
through the air valves. In closed-cir-
cuit heating systems, the cold water
filling pressure and the pre-charging
pressure of the expansion vessel
should be no less than or equal to the
height of the water head of the instal-
lation (e.g. for water head of 5 me tres,
the vessel pre-charging pressure and
installation filling pressure should be
at least 0.5 bar).
2.3.2 Water system
characteristics
Water supplying the heating circuit
must be treated in accordance with
UNI-CTI 8065 standards.
It is absolutely essential to treat wa-
ter in the heating system in the fol-
lowing cases:
– for extensive systems (with high
contents of water);
– frequent addition of water into the
system;
– should it be necessary to empty
the system either partially or
totally.
2.4
CONNECTING UP FLUE
The flue is of fundamental impor-
tance for the proper operation of the
boiler; if not installed in complian-
ce with the standards, starting the
boiler will be difficult and there will
be a consequent formation of soot,
condensate and encrustation.
The flue used to expel combustion
products into the atmosphere must
meet the following requirements:
– be constructed with waterproof
materials, and resistant to smoke
temperature and condensate;
– be of adequate mechanical resi-
