<br />~ <br />~ <br /> <br />~ NOZZLE PLACEMENT REQUIREMENTS (Continued) ~ <br /> <br />Griddle Protection <br /> <br />The R-1 02 system uses four different nozzles for the protection <br />of griddles. One of the applications requires a one-flow nozzle <br />and three of the applications require a two-flow nozzle. <br /> <br />One-Flow Griddle Protection <br /> <br />1. High Proximity Application: 35 in. to 40 in. (89 to 102 cm) <br />above the cooking surface. <br /> <br />This high proximity application uses the 1 N nozzle, Part No. <br />56930. <br /> <br />The nozzle tip is stamped with 1 N indicating this is a one- <br />flow nozzle and must be counted as one flow number. <br /> <br />One 1 N nozzle will protect a cooking area of 1080 sq. in. <br />(6968 sq. cm) with the maximum longest side of 36 in. <br />(91 cm). <br /> <br />When using this nozzle for griddle protection, the nozzle <br />must be positioned along the cooking surface perimeter to <br />a maximum of 2 in. (5 cm) inside the perimeter, and aimed <br />to the midpoint of the cooking surface. See Figure 40a and <br />40b. <br /> <br />II <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />NOTICE <br />When using this type of griddle protection, <br />only 5 flow numbers are allowed on a 1.5 <br />gallon system and only 11 flow numbers are <br />allowed on a 3 gallon system. <br /> <br />I <br /> <br />I <br /> <br />r <br /> <br />. <br /> <br />SECTION IV - SYSTEM DESIGN <br />UL EX. 3470 3-15-95 Page 4-14.1 <br /> <br />30 IN. l' <br />(76 em) 36 IN.
