3.3.3 Dismantling the skirt (fig. 9)
The shell can be completely disas-
sembled for an easy maintenance of
the boiler by following the numeric
steps shown in fig. 9.
3.3.4 Fault finding
Herefater we outline a number of
potential problems that may occur on
the appliance and the relevant list of
actions required.
A working fault, in most cases, pro-
vocates the "lock out" signal onto the
control panel of the control box.

When this light turns on, the burn-
er can operate again only after the
reset button has been pressed; if this
has been done and a regular ignition
occurs, it means the failure can be
defined momentary and not danger-
ous. On the contrary, if the "lock out"
stays, the cause of the fault, as well
as the relevant action must be made
according to the following chart:
The burner does not ignite
– Check the electric connections.
– Check the regular fuel flow, the
cleanness of the filters, of the noz-
zle and air vent from the tube.
– Check the regular spark ignition
and the proper function of the burn-
er.
The burner ignites regularly but the
flame goes out immediately
– Check the flame detection, the air
calibration and the function of the
appliance.
Difficulty in regulating the burner
and/or lack of yield
– Check: the regular flow of fuel, the
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 performances, the pre-
adjusted temperature, the correct
function and position of the regula-
