Description of operation (Fig. 1.1 and 1.2)
When the ironer control requests heating, the burner control system (H) subjects the ignition electrodes (I) to a
high voltage for a limited time to produce an electrical discharge; while power is simultaneously fed to the
solenoid valve (B) to open the gas flow.
The gas enters the burner via a single nozzle (D).
The ionisation electrode (J) detects the flame.
If the presence of a flame has not been detected after a certain time following the ignition order, the solenoid
valve is closed, an alarm report is issued and the burner control enters safety mode.
See Section 1.6. Safety and control elements.
