What determines the maximum acceptable pressure differential reading?
The answer is a reading slightly less than the point where the unit stops drawing in an acceptable level of smoke plume.
If the unit still draws acceptably at 7.0 in. H 2 O, then the controller can be set to begin the auto pulse cycle at a higher level. Please see the controller programming instructions for this procedure. If the unit stops draws acceptably at 5.0 in. H 2 O, then the controller can be set to begin the auto pulse cycle at a lower level. Please see the controller programming instructions for this procedure.
