In Reply to: Question about Spark ignitor on oil burner posted by Richard Bradley on October 26, 2001 at 06:05:09:
: Does the spark ignitor spark only at the beginning of a cycle, when the oil is first pumped and atomized or does it continually spark to keep the flame going?
Controls are made for either condition and are chosen by the manufacturer for optimum firing. Replacing one with the other, sometimes, not always, can make a noisy combustion.
