cleanness of the boiler, the non
obstruction of the smoke duct, the
real input supplied by the burner
and its cleanness (dust).
The boiler gets dirty easily
– Check the burner regulator (smoke
analysis), the fuel quantity, the flue
obstruction and the cleanness of
the air duct of the burner (dust).
The boiler does not heat up
– Control the cleanness of the shell,
the matching, the adjustment, the
burner per formances, the pre-
adjusted temperature, the correct
function and position of the regula-
tion stat.
– Make sure that the boiler is suffi-
ciently powerful for the appliance.
Smell of unburnt products
– Control the cleanness of the boiler
shell and the flue, the airtightness of
the boiler and of the flue ducts (door,
combustion chamber, smoke ducts,
flue, washers).
– Control the quality of the fuel.
Frequent intervention of the boiler
shutoff valve
– Control the presence of air in the
system, the function of the circula-
tion pumps.
– Check the load pressure of the appli-
ance, the efficiency of the expansion
tanks and the valve calibration.

ANTIFREEZE PROTECTION

In freezing weather, make sure that the
heating system continues to function
and that the rooms are kept warm
enough, including the room in which
the boiler is installed; if this cannot be
done, both the boiler and the heating
system must be completely emptied.
Completely emptying the system also
means emptying the hot water tank
and the hot water heating coil.
3.5 ANTI THERMAL
INERTIA THERMOSTAT
The purpose of the anti thermal inertia
thermostat (TI) is to restart the boiling
unit pump when the boiler reaches the
temperature of 90°C, discharging the
excess heat due to the thermal inertia
of the cast iron body towards the boi-
ling unit. The circulator will automati-
cally stop working as soon as the boiler
temperature falls below 90°C.
