We here at the marina have two 35c+ pitco fryers on site, one of the fryers has a buildup of greese inside the exhaust area of the fryer, up on the very top. At this location on the fryer it also shoots out sparks. What could be causing this malfunction or abnormal behaviour? It would be great to hear from one of the technicians in regards to this issue.
