<br />SECTION IV - SYSTEM DESIGN <br />UL EX. 3470 ULC CEx747 Page 4-7 <br />10-1-02 REV. 3 <br /> <br />Appliance Protection <br /> <br />The following pages detail types of appliance protection. Each <br />design requires several factors: correct nozzle choice, correct noz- <br />zle height above hazard, correct nozzle location and correct aim- <br />ing point. <br /> <br />Fryer - Single Nozzle Protection <br /> <br />1. Design requirements for fryers are broken down into two <br />types. <br /> <br />A. FRYERS WITHOUT DRIPBOARDS <br /> <br />If the fryer does not include a dripboard, measure the <br />internal depth (horizontal dimension from front to back) <br />and length of the frypot. <br /> <br />B. FRYERS WITH DRIPBOARDS <br /> <br />If the fryer includes any dripboard areas, measure both <br />the internal depth (horizontal dimension from front to <br />back) and length of the frypot portion, and then measure <br />the internal depth and length of the overall hazard area <br />including any dripboard areas. <br /> <br />2. Using Table, "Maximum Cooking Area Dimension - Single <br />Nozzle Fryer Protection,. determine which nozzle is needed <br />to protect the fryer based on the maximum dimensions listed. <br /> <br />A. If the fryer does not include a dripboard, use the maxi- <br />mum dimensions listed in the first column of the table to <br />select the correct nozzle. <br /> <br />B. If the fryer includes any dripboard areas, use both the <br />maximum frypot dimensions in the first column of the <br />table, and the maximum overall dimensions in the second <br />column of the table to select the correct nozzle. None of <br />the maximum dimensions in either column may be <br />exceeded. <br /> <br />3. If either the maximum frypot or the overall sizes are exceed- <br />ed, an additional nozzle(s) will be required. Refer to the mul- <br />tiple nozzle requirements. <br /> <br />Example: A fryer with a dripboard. The inside of the frypot without <br />the dripboard measures 18 in. in depth x 18 in. in length (46 em x <br />46 em) and the insIde of the overall area including the dripboard <br />measures 18 in. in depth x 24 in. in length (46 em x 61 em). From <br />the Table "Maximum Cooking Area Dimension - Single Nozzle <br />Fryer Protection, " either the 3N or the 290 nozzle should be select- <br />ed to protect the fryer, depending on the maximum nozzle height <br />above the fryer and the positioning requIrements a/lowed. Refer to <br />appropriate Figures. <br />
