Description of operation (Fig. 1.1)
When the dryer control requests heating, the
burner control system (B) activates the ignition
electrode (G) to generate a spark;
simultaneously power is fed to the solenoid
valve (C) to open the gas flow.
The gas enters the burner via a single nozzle
(D).
The ionisation electrode (H) detects the flame.
If the presence of a flame has not been
detected after a certain time following the
ignition order, the solenoid valve closes, an
alarm report is issued and the burner control
enters safety mode.
For further information refer to paragraph 1.6. Protection, safety and control elements.
