CRN Requirment
Can anyone tell me at what size/volume a vessel for Anhydrous Ammonia is required to have a CRN? I have several small oil pots that do not have CRNs and need to put on relief regulators but need to know if I have to change out the oil pots as well or are they small enough that they do not require a CRN
