The shell can be completely disas-

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
burner 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 dangerous.
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 follow-
ing chart:
The burner does not ignite
– Check the electric connections.
– Check the regular fuel flow, the
cleanness of the filters, of the
nozzle and air vent from the tube.
– Check the regular spark ignition
and the proper function of the
burner.
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 quan-
tity, 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 regu-
lation stat.
– Make sure that the boiler is suffi-
ciently powerful for the appliance.
