Current through Register Vol. 50, No. 6, June 20, 2024
A. Each boiler
				  shall have a feed supply which will permit it to be fed at any time while under
				  pressure.
B. A boiler having more
				  than 500 square feet of water heating surface shall have at least two suitable
				  means of feeding, at least one of which shall be a feed pump. A source of feed
				  at a pressure 6 percent greater than the set pressure of the safety valve with

				  gaseous, liquid, or solid fuel in suspension may be equipped with a single
				  means of feeding water provided means are furnished for the shutoff of heat
				  input prior to the water level reaching the lowest safe level.
C. The feed water shall be introduced into a
				  boiler in such a manner that the water will not be discharged directly against
				  surfaces exposed to gases of high temperature to direct radiation from the
				  fire. For pressures of 400 psig over, the feed water inlet through the drum
				  shall be fitted with shields, sleeves, or other suitable means to reduce the
				  effects of temperature differentials in the shell or head.
D. The feed piping to the boiler shall be
				  provided with a check valve near the boiler and a valve or cock between the
				  check valve and the boiler. When two or more boilers are fed from a common
				  source, there shall also be a valve on the branch to each boiler between the
				  check valve and the source of supply. Whenever a globe valve is used on feed
				  piping, the inlet shall be under the disk of the valve.
E. In all cases where returns are fed back to
				  the boiler by gravity, there shall be a check valve and stop valve in each
				  return line, the stop valve to be place between the boiler and the check valve,
				  and both shall be located as close to the boiler as practicable. It is
				  recommended that no stop valves be placed in the supply and return pipe
				  connections of a single boiler installation.
F. Where deaerating heaters are not employed,
				  it is recommended that the temperature of the feed water be not less than
				  120° F to avoid the possibility of setting up localized stress. Where
				  deaerating heaters are employed, it is recommended that the minimum feed water
				  temperature be not less than 215° F so that dissolved gases may be
				  thoroughly released.

				  of manufacture with a permanent marker indicating the lowest permissible water
				  level. The marker shall be stamped, etched, or cast in metal; or it shall be a
				  metallic plate attached by rivets, screws, or welding; or it shall consist of
				  material with documented tests showing its suitability as permanent marking for

				  shipped with a jacket, this marker may be located on the jacket.
E. In electric boilers of the submerged
				  electrode type, the water gage glass shall be so located to indicate the water
				  levels both at startup and under maximum steam load conditions as established
				  by the manufacturer.
F. In electric
				  boilers of the resistance heating element type the lowest visible part of the
				  water gage glass shall not be below the top of the electric resistance heating
				  element. Each boiler of this type shall also be equipped with an automatic
				  low-water electrical power cutoff so located as to automatically cut off the
