<p>An oil burner control system is disclosed in which an extended time may be temporarily selected, in situations such as initial set up or periodic maintenance, for priming the pipes, filters and pumps, before a safety lockout of system operation occurs, while otherwise leaving the normal safety lockout functions intact. An igniter in the system operates in an 'intermittent' mode during the temporarily selected extended time, and otherwise operates in an 'interrupted' mode.</p> |
