Nozzles must be located 2-8 In.(51-203 mm)into the center used on a number of different types of restaurant cooking appli• of the duct opening,discharging up. See Figure 4.1, antes and hood and duct configurations,The design information listed in this section deals with the limitations and parameters of this pre-engineered system. Those Individuals responsible for the design of the R-102 system must be trained and hold a current ANSUL certificate in an R-1o2 training program. The R-102 and they PIRANHA systems use compatible agents and components, therefore, they may be used together for cooking appliance, hood, and duct protection. The primary AUTOitMAN Release can be either an R-102 or a PIRANHA r� AUTOMAN Release and can actuate up to two additional R-102 or PIRANHA Regulated Actuators. In systems utilizing a 101 a•-e IN, remote release, any combination of the maximum number of ssi-=�m^) ! regulated actuators can be used. i • Both systome must aotuats simuitansously. • Each system must be designed and installed per its appropri- FIGURE 4-1 ate Mandel.
