tapping screws;
– disassemble the left side (3) un-
screwing the screws fixing it to the up-
per bracket (5), and remove the screws
that fix it to the lower bracket (1);
– disassemble the right side (4) fol-
lowing the same operations.
3.3.4 Fault finding
Herefater we outline a number of poten-
tial problems that may occur on the
appliance and the relevant list of actions
required. A working fault, in most cases,
provocates 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 clean-
ness 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 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 tem-
perature, the correct function and
position of the regulation stat.
– Make sure that the boiler is sufficiently
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).
52
– 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 circulation
pumps.
– Check the load pressure of the appli-
ance, the efficiency of the expansion
tanks and the valve calibration.
3.4 FROST PROTECTION
In the event of frost, ensure that the
central heating plant is functional and
effective frost protection interlocks are
in place to protect against frost damage
3.5 USER WARNINGS
It is mandatory that the dedicated power
cable is replaced only with a spare cable
ordered and connected by professionally
qualified personnel.
ATTENTION: Before performing any
work on the boiler, make sure that the
same and its components have cooled in
order to prevent the risk of burns due to
high temperatures.
3.6 DISPOSAL OF THE EQUIPMENT
(2012/19/UE)
Once it reaches the end of its
operating life, the equipment
MUST BE RECYCLED in line
with current legislation.
IT MUST NOT be disposed of
together with urban waste.
It can be handed over to recycling centres,
if there are any, or to retailers that offer
this service.
Recycling prevents potential damage to the
environment and health. It allows to reco-
ver a number of recyclable materials, with
considerable savings in terms of money
and energy.
