Pentair manual for MasterTemp pool heater indicates that model 250 coil requires 8 O-ring seals. This would suggest that the coil has 4 tubes. However, some other sources state that the coil of the 350 model has 6 tubes. Which one is correct and what is the size (inside diameter and length) of the tubes?
