Thereafter, the manufacturing drawings and the particulars of materials, design and construction shall be sent to the Chief Inspector of Boilers of the State where the boiler will be installed and used, for final examination and approval before commencement of manufacture so as to avoid questions arising at the time of erection and registration of the boiler.
