N.Y. Comp. Codes R. & Regs. Tit. 12 §§ 14-11.8
Current through Register Vol. 46, No. 53, December 31, 2024
Each miniature boiler for operation with a definite water level shall be equipped with a glass water gage for determining the water level. The lowest permissible water level shall be at a point one-third of the height of the shell, except where the boiler is equipped with internal furnace, when it shall be not less than one-third of the length of the tubes above the top of the furnace. In the case of small steam generating units operated on the closed system where there is insufficient space for the usual glass water gage, water level indicators of the glass bulls-eye type may be used.
