Each design requires several factors:correct nozzle choice,correct noz- zle height above hazard, correct nozzle location and correct aim- ing point. Fryer—Single Nozzle Protection 1. Design requirements for fryers are broken down into two types. A. FRYERS WITHOUT DRIPBOARDS If the fryer does not include a dripboard, measure the internal depth (horizontal dimension from front to back) and length of the frypot. 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 maxi- mum 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 exceed- ed, an additional nozzle(s) will be required. Refer to the mul- tiple 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 (46 cm x 46 cm) and the inside of the overall area including the dripboard measures 18 in.in depth x 24 in. in length (46 cm x 61 cm). From the Table `Maximum Cooking Area Dimension — Single Nozzle Fryer Protection,"either the 3N or the 290 nozzle should be select- ed to protect the fryer, depending on the maximum nozzle height above the fryer and the positioning requirements allowed.Refer to appropriate Figures.

B. FRYERS WITH DRIPBOARD(S) If the fryer includes any dripboard areas, measure both the internal depth and length of the frypot portion, and then measure the internal depth and length of the overall hazard area including any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding depth and length dimensions. 2. Divide the frypot or overall vat into modules,each of which can be protected by a single nozzle, based on the maximum dimension and area coverage of the nozzle as specified in Table, "Maximum Cooking Area Dimension — Multiple Nozzle Protection." A. If the module considered does not include any portion of the dripboard, use only the maximum frypot area and max- imum dimension listed in the first column of the table to select the correct nozzle. B. If the module considered includes any dripboard areas, use both the maximum frypot area and dimension listed in the first column of the table,and the maximum overall area and dimensions listed in the second column of the table to select the correct nozzle. 3. None of the maximum dimensions in either column may be exceeded.If either the maximum frypot or the overall sizes are exceeded,the area divided into modules will need to be rede- fined with the possibility of an additional nozzle.
