SECTION IV — SYSTEM D�S[t3N <br /> UL EX3470 ULC EX3470 Page 4-7 <br /> 10-1-02 FiEV.3 <br /> Applfance Protectton <br /> The following pages detail types of appliancs protection. Each <br /> design requires several iactors:correct noute choice,cnrrect noz- <br /> zte height above hazard,correct nozzle location and correci aim- <br /> ing point. <br /> Fryer—Single Noule Protection <br /> 1. Deslgn requirements tor fryers are broken dow� 'snto two <br /> iypes. <br /> A. FRYERS W{THOUT DRIPBOARDS <br /> It the frysr does not Inctude a dripboard, measure the <br /> internal depth (horizontal dimenslon irom front ta back} <br /> and length of the frypot. <br /> e. FRYEFtS WITH DRIPB�ARDS <br /> ff tha fryer includas any dripboard areas,measure both <br /> the internal depth (horizontal dimension from front to <br /> back)and length of the frypot poriian,and then measure <br /> the intemai depth and length of the overalt hazard area <br /> i�cluding any dripboard areas. <br /> 2. Using Table, °Maximum Cooking Area Dimension—Single <br /> Noule Fryer Protection,"determine which nozzle is�eeded <br /> to protect ihe fryer based on the maximum dimensfons Itsted. <br /> A. If the iryer does not include a dripboard, use the maxi- <br /> rnum dimensions listed in the first column of the table to <br /> select the correct nozzle. <br /> B. If the fryer includes any dripboard aress, use both 1he <br /> maximum lrypot dlmensions in the tirst calumn of the <br /> table,and the maximum rneralt dimensions in the second <br /> column of the tabfe to select the correet noufe.None of <br /> the maximum dimensions in either column may be <br /> exceeded. <br /> 3. If either the maximum frypot or ihe overall sizes are exceed- <br /> ed,an addiiional nozzle(s)will be required.Refer lo!he mui- <br /> tipie nozzle requirements. <br /> Example:A tryer with a dripboard.The insrde of lhe frypof without <br /> tha dripboard measures 16 in.in depth x 18 in.ln length(q6 cm x <br /> 46 cmJ and the fnslde of lhe averal!area including the drlpbaard <br /> measures 1 B in.!n depth x 24 in.in length(46 cm x 61 cm).From <br /> fhe Tab/e "Maximum Cooking Area Dlmension —5ingle Noule <br /> Frysr Protection,"either the 3N or the 29D noule should be select <br /> ed tp pm(ect the fryer,dependlnq on the maximum nozzle helght <br /> above the fryer and the posfUpning requirements a!lowed.Refer to <br /> appropriate Figures. <br />
