3.5 - ASSEMBLY
The AIREX boiler does not differ from a normal solid fuel fired boi-
ler; therefore there are no particular installation codes of practice
other than the safety provisions foreseen by standards in force.
The installation room must be properly ventilated by
openings with a total surface of at least 0.5 m².
To make it easier to clean the smoke circuit,
in front of the boiler, there must be a
free space no less than the
length of the boiler.
Check at least that the doors can open 90°
without meeting any obstacles.
The boiler can be placed directly on the floor,
as it is equipped with a self-supporting frame.
Nevertheless, in case of installation in very
damp boiler rooms, it is preferable to provide
cement support.
When installation has been performed, the
boiler must be in a horizontal position and
stable so as to reduce possible vibrations
and noise.
An adequate clearance space must be left behind the
boiler to allow the fan to be opened and serviced.
POSITIONING IN
BOILER ROOM
N.B.: The minimum clearances indicated to the side are
required to allow the AIREX boiler correct maintenance.

3.6 - CONNECTING BOILER
TO SYSTEM
Attention!
Make sure that there are no mechanical
stresses while connecting the pipes to avoid
the risk of leakage!
Heating flow and return pipes must be connected
to the boiler at the respective fittings as indicated on page 7.
For the dimensioning of the heating circuit pipes, you must take
into account pressure drops caused by radiators,
thermostatic valves, radiator stopping valves and by the
configuration of the system.
The laying of the pipes must be designed taking every neces-
sary precaution to avoid air pockets and to facilitate continuous
degassing of the system.
Make sure that the pipes of the water and heating
system are not used as earthing electrodes of
the electric or telephone system.
They are absolutely not suitable for this type of
use. Serious damage could result for the piping,
boiler and radiators in a short amount of time.
