Balanced piping is that in which the difference between the shortest actual pipe length <br /> from T1 to nozzle and the longest actual pipe length from T1 to nozzle does not exceed 10% of the longest actual pipe <br /> Iength from Ti to nozzle. T2 to nozzle on the same branch must not exceed 10% of each other. The number and type of <br /> fittings for all last tee to nozzle sections must be equal <br /> 3. A Main/Reserve Swing Check Valve, Part No. 417788, may be Iocated between the cylinder and T1 <br /> 4. Minimum requirements for piping and fittings do not apply to systems protecting hazards with no splashable hazard. A <br /> splashable hazard exists where liquid fuel in depth greater than 1/4 in. is present. <br /> ULEX 3437 Csn732 <br /> September 1, 2006 <br />
