4.12 Flame control RMG88...
Warnings
To avoid accidents, material or environmental
damage, observe the following instructions!
The flame control RMG88... is a safety device!
WARNING
Avoid opening or modifying it, or forcing its opera-
tion. Riello S.p.A. cannot assume any responsibil-
ity for damage 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.

Mechanical structure
The flame control is made of plastic to resist knocks, heat and
flame propagation.
The flame control contains the following components:
• a microprocessor that controls the program sequence, and a
relay for controlling the load
• an electronic flame signal amplifier
• a built-in reset button with 3 signalling colours (LED) for status
and error messages.
