.J)ECTION IV - SYSTEM DESIGN UL EX. '3470 3-15-95 Page 4-10.2 ~ NOZZLE PLACEMENT REQUIREMENTS (Continued) Multiple Nozzle Fryer Protection - 2-Flow High Proximityl 2-Flow Low Proximity (Continued) FRYERS WITH DRIP BOARDS (Continued) To properly protect this hazard with multiple nozzles, divide the surface area into modules not exceeding 294 sq. in. (1897 sq. cm) (cooking area plus drip board area) and 210 sq. in. (1355 sq. cm) of fry pot only. When dividing into modules, the longest side of each module must not exceed 21 in. (53 cm). See Figure 33b. THIS IS TOTAL MODULE AREA WITHOUT DRIP BOARD 21 IN. (53 eml MAXIMUM DIMENSION (COOKING AREA NOT TO EXCEED 210 so. IN.

(1897 sq. em) MAXIMUM FIGURE 33b The R-102 system uses two different style nozzles for this protection. 1. High Proximity Applications: 27 to 47 in. (69 to 120 cm) above the top surface of fryer. See Figure 33c. The 230 Nozzle (Part No. 418117) is used for high prox- imity applications. The nozzle tip is stamped with 230, 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 anywhere along or within the perimeter of the area it is protecting and aimed at the mid point of the respective modular area. 2. Low Proximity Applications: 20 to 27 in. (51 to 69 em) (above top surface of fryer. See Figure 33c. The 245 Nozzle (Part No. 418118) is used for low proximity applications. The nozzle tip is stamped with 245, indicating that this is a two-flow nozzle and must be counted as two flow numbers. To protect each area, the nozzle tip must be located within the perimeter of the area it is protecting and aimed at the mid point of the respective modular area. See Figure 33c. ~ ~ POSITION NOULE TIP ANYWHERE ALONG OR WITHIN THE PERIMETER OF THE AREA IT IS PROTECTING AND AIM AT MIDPOINT OF THAT MODULAR AREA. .-- ___ ___ 1'- "- "- rC I "- I '.......
