Low Proximity Application: 13 to 16 in. (33 to 41 cm) above top surface of fryer. See Figure 33t. The 290 Nozzle, Part No. 418120, is used for low proximity applications. The nozzle tip is stamped with 290, indicating that this is a two-flow nozzle and must be counted as two flow numbers. When using this nozzle for fryer protection, the nozzle tip must be positioned over the midpoint of the respective modular area + 1- 3 in. from the midpoint along the lon- gest side of the module and + 1- 1 in. from the midpoint along the shortest side of the module and aimed at the mid- point. See Figure 331. 290 NOZZLE TIP MUST BE POSITIONED OVER THE MIDPOINT OF THE RESPECTIVE MODULAR AREA ;f; 3 IN. (7.6 em) FROM THE MIDPOINT ALONG THE LONGEST SIDE OF THE MODULAR AND ;f; I IN.

High Proximity Application: 40 in. to 50 in. (102 cm to 127 cm) above the cooking surface. The high proximity application uses the 245 nozzle, Part No. 418118. The nozzle tip is stamped with 245 indicating this is a two- flow nozzle and must be counted as two flow numbers. One 245 nozzle will protect a cooking area of 672 sq. in. (4335 sq. em) with maximum dimensions of 28 in. x 24 in. (71 cm x 61 em). When using this nozzle for range protection, the nozzle must be pointed vertically down and positioned as shown in Figures 34 and 35.
