When any boiler is designed at Reimers the path involves using ASME code rules for fabrication. Reimers is an ASME E Stamp holder and is allowed to test and plate boilers with the E designation. As a result the vessel becomes ASME stamped and meets the requirement for UL to then be further reviewed and tested to meet the safety and operational needs of UL, CSA and other codes. NEC and NFPA guidance is necessary for installation by field technicians.
