3.10 Flame control

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. Riello
S.p.A. cannot assume any responsibility for dam-
age resulting from unauthorised interventions!
 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). Check the system is not powered
and cannot be accidentally reconnected. Failure to do this
will lead to the risk of electrocution.
 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.
 Press the reset button of the burner lockout command or the
reset button (by applying a force of not more than 10 N),
without the aid of tools or sharp objects.
For the safety and reliability of the flame control, comply with
the following instructions:
– avoid conditions that can favour the development of conden-
sate and humidity. Otherwise, before switching on again,
make sure that the entire 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 electric wiring inside the boiler complies with the
national and local safety 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 that AC 230 V mains voltage
cables are run strictly separate from extra low-voltage cables
to avoid risks of electrical shock hazard.
