If this is a field installed unit make sure the concave is zero'd - we have had to remove the jam nuts to get the grate right. Also be sure to move the lower grate up and rezero the 'mid min max' gauges. We have been running very close - 1 in most cases because the late freeze and droughthas really caused problems. We see little loss of capacity - even this close. If you can run 2-4, great. Otherwise sets just like reg cyl.
