Used or secondhand boiler control systems shall be upgraded to meet the requirements of the current adopted edition and addenda of ASME CSD-l or the appropriate NFPA standard before they are operated. Reinstalled boilers, as defined in 229 NAC 1, are not required to have the controls upgraded when they are relocated, unless the controls have to be modified for the new location or the use of the boiler has changed.
