Flame control
The flame control is a check and supervision system for forced
draught burners, for intermittent operation (at least one controlled
shutdown every 24 hours).
Important notes
To avoid accidents, material or environmental
damage, observe the following instructions!
The flame control is a safety device! Avoid open-
WARNING
ing or modifying it, or forcing its operation. The
Manufacturer cannot assume any responsibility
for damage resulting from unauthorised work!
All interventions (assembly and installation operations,
assistance, etc.) must be carried out by qualified personnel.
Before modifying the wiring in the flame control connection
area, fully disconnect the system from the power supply
(omnipolar separation).
Protection against electrocution from the flame control and
all connected electric components is obtained with the cor-
rect assembly.
Before any intervention (assembly and installation opera-
tions, assistance, etc.), ensure the wiring is in order and that
the parameters are correctly set, then make the safety
checks.
Falls and collisions can negatively affect the safety func-
tions. In this case, the flame control must not be operated,
even if it displays no evident damage.
For safety and reliability, comply with the following instruc-
tions:
–
avoid conditions that can favour the development of conden-
sate and humidity. Otherwise, before switching on again,
make sure the flame control is perfectly dry.
–
Static charges must be avoided since they can damage the
flame control's electronic components when touched.
Installation notes
•
Check the electrical wiring inside the boiler complies with the
national and local safety regulations.
•
Install switches, fuses, earth connection etc. in compliance
with local regulations.
•
Do not confuse the powered conductors with the neutral
ones.
•
Ensure that spliced wires cannot get into contact with neigh-
bouring terminals. Use adequate ferrules.
•
Arrange the H.V. ignition cables separately, as far as possi-
ble from the flame control and the other cables.
•
When wiring the unit, make sure the 230V AC mains voltage
cables are run strictly separate from extra low-voltage cables,
to avoid the risk of electrocution.
Technical description of the burner
11
GB
To remove the flame control from the burner it is necessary to
(Fig. 4):
disconnect all the connectors connected to it, all the plugs,
the high voltage cables and the earth wire (TB);
unscrew the screw (A) and pull the flame control in the direc-
tion of the arrow.
To install the flame control it is necessary to:
tighten the screw (A) with a tightening torque of 1 - 1.2 Nm;
reconnect all previously disconnected connectors, making
sure to connect the 7 pin plug as the final step.

NOTE:
The burners have been approved for intermittent operation.
This means that they must stop once every twenty four
hours to permit the flame control to check its efficiency at
start-up. The boiler limit thermostat (TL) normally ensures
the stopping of the burner. If this is not the case, it is neces-
sary to apply a timer switch in series to the limit thermostat
(TL) that turns off the burner at least once every 24 hours.
Electrical wiring of the flame sensor
It is important for signal transmission to be almost totally free
of any disturbances or loss:
•
Always separate the flame sensor cables from the other ca-
bles:
– the line capacity reduces the magnitude of the flame sig-
nal.
