c SECTION IV — SYSTEM DESIGN L EX. 3470 7-1-96 Page 4-19 REV. 1 NOZZLE PLACEMENT REQUIREMENTS (Continued) Nieco Broiler With Catalytic Converter Protection Certain models of the Nieco broiler (Models 940, 962. and 960) are equipped with a catalytic converter to comply with new clean air laws. Because of the converter, it is necessary to protect these broilers in a special way. The guidelines for protecting these broilers are as follows: — The maximum internal broiling area is 29 in. x 23.5 in. (74 cm x 60 cm). — An R-102 3-gallon system with a maximum of 6 flow numbers, must be used for protection of each broiler, including plenum and duct. — Each individual broiler must be protected with a minimum of (2) two, 1 N nozzles, Part No. 419335. The nozzles must be located as shown in Figure 50. — The broiler must be fitted with two 1 in. (2.5 cm) high agent barriers on the angled surface of the broiler. See Figure 50. If these have not been completed by the equipment sup- plier, they must be added in the field. 30• (ZI 114 NOZZLES PART NO. 56M o a (3 251 IN. (7b <m) 121N.

(35 M) I FIGURE 50 Upright/Salamander Broiler Protection ► The R-102 system uses two 1 /2N Nozzles (Part No. 419334) for all upright/salamander broiler protection. The nozzle tip is stamped 1;2N, indicating that this is a half -flow nozzle. A pair of these nozzles will equal one flow number. Two 1/2N broiler nozzles will protect a hazard area (internal broiler chamber) of 30 in. x 32.5 in. (76 cm x 82.5 cm). These nozzles must always be used in pairs on an uprighUsalamander broiler. One nozzle must be positioned above the grate and pointed at the back opposite corner of the broiler chamber. The second nozzle must be painted dawn into the center of the drip pan through the open slot. See Figure 51. SALAMANDER BROILER I UPRIGHT BROILER BROILER CHAMBER SIDE VIEW FIGURE
