One of the applications requires a 1-flow nozzle and .30 in.to 50 in.(76 cm to 127 cm)above the cooking surface. <br /> three of the applications require a 2-flow nozzle. <br /> High Proximity Applicatlon:35 in.to 40 in.(89 to 102 cm)above This high proximity application uses the 290 nozzle, Part No. <br /> the cooking surtace. 419342. <br /> This high proximity application uses the 1 N nozzie, Part No. The nozzle tip is stamped with 290 indicating this is a 2-fiow noz- <br /> 419335. zle and must be counted as two flow numbers. <br /> The nozzle tip is stamped with 1 N indicating this is a one-flow noz- 'One 290 nozzle will protect a maximum cooking area of 720 in.2 <br /> zle and must be counted as one flow number. ' (4645 cm2)with a maximum dimension of 30 in.(76 cm). <br /> One 1 N nozzle will protect a maximum cooking area of 1080 in.2 When using this nozzle for high proximity applications,the nozzle <br /> (6968 cm2)with the maximum longest side of 36 in.(91 cm). must be positioned within 1 in.(2.5 cm)of the center of the cook- <br /> ►ing surface and pointed vertically down.See Figure 41 and 42. <br /> Whan using this nozzle for griddle protection,the noule must be <br /> positioned along the cooking surface perimeter to a maximum of CENTER LINE UF ORIDDLE <br /> 2 in.(5 cm)inside the perimeter,and aimed to the mid oint of the SURFACE t/IN.(2 cm)IN <br /> p ANY DIRECTION <br /> cooking surtace.See Figure 39 and 40. � �_� <br /> NOTICE � <br /> I <br /> When using this type of griddle protection,only � , � 501N. <br /> 5 flow numbers are allowed on a 1.5 gal(5.7 L) � � c�z��m� <br /> system and only 11 flow numbers are allowed � I HEIOHTM <br /> on a 3 gal(11.4 L}system. � oF 2so <br /> i � � NOZZLE TIP <br /> j � 301N. <br /> � � � (76 cm) <br /> MINIMUM <br /> r MIDPOINT OF^ � � <br /> HFIOHT <br /> ( � COOKINQ SURFACE I i I NqZZLE <br /> � � i TI�P <br /> i '�'f � I i <br /> I � <br /> L-------.LJ <br /> 7N NOZZLE LOCATED ALONO COOKING SURFACE EDGE <br /> ANY SIDE OF GRIDDLE SURFACE ► <br /> WITHIN 0—2 IN.(0—5 cm)OF FIGURE 41 <br /> COOKING SURFACE EDGE.NOZZLE 0002u <br /> MUST BE AIMED AT MIDPOINT OF <br /> COOKINd SURFACE.
