24 K. CHECK FOR CLEAN CUT OFF OF BURNER. 1. AIR IN THE OIL LINE between fuel unit and nozzle will compress when burner is on and will expand when burner stops, causing oil to squirt from nozzle at low pressure as burner slows down and causing nozzle to drip after burner stops. Usually cycling the burner operation about 5 to 10 times will rid oil li[...]

25 d. Dismount the low water cutoff control from the probe. e. Unscrew the probe from the boiler tapping. f. Inspect that portion of the probe that is exposed to the boiler water for a scale or sediment buildup. g. Light deposits may be removed by wiping the probe with a damp cloth. Wiping the probe with a cloth soaked in vinegar will remove more t[...]
