Once the release temperature is reached and the oil preheater’s thermostat cuts in, the burner motor will start the pre-purge and power will simultaneously be applied to the ignition (TT). Following the pre-ignition and pre-purge time, the oil will be released by valve V1 being opened and subsequently V2 will be opened.
