Design requirements for fryers are broken down into two types. A. FRYERS WITHOUT DRIPBOARDS i If the fryer does not include a dripboard, measure the internal depth (horizontal dimension from front to back) 1 f and length of the frypot. 1 B. FRYERS WITH DRIPBOARDS If the fryer includes any dripboard areas, measure both the internal depth (horizontal dimension from front to back)and length of the frypot portion,and then measure the internal depth and length of the overall hazard area including any dripboard areas. • 2. Using Table, "Maximum Cooking Area Dimension-Single Nozzle Fryer Protection,"determine which nozzle is needed to protect the fryer based on the maximum dimensions listed. A. If the fryer does not include a dripboard, use the maximum dimensions listed in the first column of the table to select the correct nozzle. B. If the fryer includes any dripboard areas, use both the maximum frypot dimensions in the first column of the table, and the maximum overall dimensions in the second column of the table to select the correct nozzle. None of the maximum dimensions in either column may be exceeded. 3. If either the maximum frypot or the overall sizes are exceeded,an additional nozzle(s)will be required. Refer to the multiple nozzle requirements. Example: A fryer with a dripboard. The inside of the frypot without the dripboard measures 18 in, in depth x 18 in. in length (457 mm x 457 mm) and the inside of the overall area includ- ing the dripboard measures 18 in. in depth x 24 in, in length (457 mm x 610 mm). From the Table "Maximum Cooking Area Dimension - Single Nozzle Fryer Protection, either the 3N or the 290 nozzle should be selected to protect the fryer, depend- ing on the maximum nozzle height above the fryer and the positioning requirements allowed.
