Then, 15 seconds later (pre-purging time) the igniter is activated and the gas pressure regulat-
ing valve opens. After 7 seconds the gas pressure regulating valve closes and the igniter is
de-energized (due to missing ignition).
Note: On multi-burner units, this process is successively completed for all burners.
