Chapler 3 - Syslem DesIgn . Page 3-18 REV. 1 Step No.5 Check 10 make certain mInimum volumes end maximum volume allowed between first nozzle and lasl nozzle are not exceeded (Tenk Chert). Check each rule In "General PipIng Requirements" 10 make certain nDne have been exceedad. If any requirement Is exceeded, changa 10 a different pipe size and recalculale. See Figure 3-22. Refer to Tank Chart MinImum Pipe Volume for PCL-300 15 300 mlllllllers protecllng a fryer, wok, or range (Example sYBlem pIpe volume Is 1781 mlll/lIlers, lharefore OK) Maximum PIpe Volume for PCL.300 Is 1910 milliliters (Example system pipe volume Is 1781 mlllflflars, Iherefore OK) MaxImum Volume Allowed Between First Nozzle and Last Nozzle for PCL-300 Is 1125 mIllIliters (Example system, the amount of 318 In. piping belween G and L, Is 25.5 feel. 25.5 feet x 37.5 mls./ft. = 956.3 ml, therefore, OK) Refer to General Piping RequIrements 1. Split ptplng and stratght pipIng are both allowed on PCL-300 and PCL-460 systems. (Example syslem OK) 2. PCL-600 systems must use split pipIng only, with no nozzle located bBfore the split, and wllh a maxImum of 14 flDW poInts per side. 1/2 In. minImum piping must be used up to the first spill. (Example system N/A) 3. Maximum volume for 1/4 In. pIpe between a nozzle and the precedIng tee Is 410 mls. (Example system N/A) 4. MaxImum flow numbers for 1/4 In. pipe Is 6. (Example system N/A) 5. Maximum number of elbows botwoBn e nozzle and the preceding too Is 5. (Example syslem has a maximum number of 2, lherefore, OK) 6. MaxImum of 25 elbows are aI/owed In the total pIpIng system. (Example Syslem has 11 elbows, therefora, OK) 7. MaxImum dIfference In elevation between the tank outlet end any nozzle, or the tank outlet and the highest or lowest horIzontal pIpe run, Is 10ft. (3.1 m) (Example syslem has 5'-6" (1.7 m). therefore, OK) 8. ND traps are allowed In the pIpIng network. (Example sYBlem has nD lraps, tharefore, OK) 9. PIpe lengths are measured from center to center of fIttings. (Example syslem pipe lengths were meesured from cenler 10 conter of fittings, therefore. OK) ULEX 3830 April 1, 2004 PN551274(2) 10. The Internal equivalent length volume Df flllIng8 doen not have 10 be considered as part of the total pIpe volume. (Example system OK) 11. When utilizIng different sIze pipe In Ihe total system, the largest sIze must start first and the addItional pIpe must decrease liS It approaches the nozzle. (Example syslem N/A) 12. Elbow(s) or swIvel adaptors located at the nozzles do not have to be counted In the 25 elbow mBxlmum requirement. (Exemple syslem OK) 13. AddltlonBI pipIng requirements when protecting B range, wok, or a fryer: . PCL-300 - MInimum of 300 ml and four (4) flow numbers required In total system. Of that mInimum, 239 ml and two (2) flow numbers must be ullllzed at or before the range, wok, or fryer. (Example syslem has 1781 ml and 10 flDW numbers, Iherefore, OK. The exam- ple sYBlem has 1050 ml and 3 flows Including Ihe fryer. Iherefore, OK) PCL-460 - MInimum of 660 ml and len (10) fiDW numbers required In lolel system. Of that mInImum, 180 ml and two (2) flow numbers must be utilIzed at or belore (he range, wok, or fryer. peL-600 - MinImum of 960 ml and four- teen (14) flow numbers required In lolal sYBtem. Of Ihat mInimum, 120 ml and 2 flow numbers must be ullllzed al or before the range, wok, or fryer. TANK CHART . MAX. VoL. BETWEEN FIRST AND LAST NOZZLE GEN. PIPING RULE NO. 12 GEN.
