First  on a Carlin burner  s/s  i am assumeing  service man switch  because looks like in series  before the primary  ? second not really oil guestion  but if im adding  a unit heater  to  one pipe  system  and one venturi/monoflow tees  and cannot get the propper pressure differential from one tee  do i just flip the tee on the return side or do i need a special tee  for this?

    my mentor used to tell all our rookies, coming back from nify to forget what they learned,and be ready for his training,in the real world.looks like you want to run before you learn how to walk.good luck.
