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 111
ANSUL certificate in an R-102 training program.
The R-102 and the PIRANHA systems use compatible agents and
components, therefore, they may be used together for cooking
appliance, hood, and duct protection. The primary ANSUL
AUTOMAN Release can be either an R-102 or a PIRANHA ANSUL AUTOMAN Release and can actuate up to two additional 111111111111111

'Exceptions:
1.Twelve(12)flow numbers are allowed in any one tank for duct and plenum protection only.
2.Twelve(12)flow numbers are allowed with any one tank using only two-flow appliance nozzles.
3.Twelve(12)flow numbers are allowed with any one tank using only three-flow appliance nozzles.
Special Instructions:
1.Twelve(12)flow numbers are allowed when four(4)Dean Industries GTI Gas Fryers are protected at low proximity as shown in Figure 66 on Page 4-32.The discharge piping must
r. be as shown in Figure 67 on Page 4-32.
