SECTION IV - SYSTEM DESIGN C Ulf EX. 3470 7.1-96 Page 4.20 REV. 2 NOZZLE PLACEMENT REQUIREMENTS (Continued) Electric Char -Broiler Protection The R-102 system uses the IN nozzle for the protection of elec. tric char -broilers. The maximum length of the hazard can be no longer than 34 in. (86 cm) and the total hazard area must not exceed 680 sq. in. (4386 sq. cm). 1. Nozzle Location: 20 to 50 in. (51 to 127 cm) above the grate surface. The 1 N Nozzle (Part No. 419335) is used for electric char - broiler applications. The nozzle tip is stamped with IN, indicating that this is a one -flow nozzle and must be counted as one flow number. When using this nozzle for electric char -broiler protection, the nozzle must be positioned anywhere along or within the perimeter of the maximum hazard area and shall be aimed at the center of the cooking surface.

The nozzle tip on the IN nozzle is stamped with a IN, indicating that this is a one -flow nozzle and must be counted as one flow number. The nozzle tip on the 245 nozzle is stamped with 245, indicating that this is a two -flow nozzle and must be counted as two flow numbers. One IN nozzle will protect a hazard with a maximum length of 24 in. (61 cm) and a total area which does not exceed 528 sq. in. (3406 sq. cm). The nozzle tip must be located 26 to 40 in. (66 to 102 cm) above the hazard surface. When using this nozzle for gas -radiant char -broiler protection, the nozzle must be located within a t in. (2.5 cm) radius of the center of the grate area and shall be aimed at the center of the area. See Figure 53. .? 26 - MO IN.

The nozzle tip must be located 18 to 40 in. (46 to 102 cm) above the hazard surface. When using this nozzle for gas -radiant char -broiler protection, the nozzle must be positioned anywhere along or within the perimeter of the max- imum hazard area and shall be aimed at the center of the cooking surface.
