Current through Supplement No. 393, July, 2024
1. Each miniature
				boiler must be equipped with an American society of mechanical engineers
				approved safety valve set at or below the maximum allowable working
				pressure.
2. The safety valve must
				be plainly marked by the manufacturer showing name or identifying trademark,
				nominal diameter, and pressure at which it is set to release.
3. The safety valve relieving capacity of
				each boiler must be such that it will discharge all the steam that can be
				generated by the boiler without allowing the pressure to rise more than six
				percent above the maximum allowable working pressure.
4. In those cases where the boiler is
				supplied with feedwater directly from a pressure main or system without the use
				of a mechanical feeding device, the safety valve must be set to release at a
				pressure not in excess of ninety-four percent of the lowest pressure obtained
				in the supply main or system feeding the boiler. Return traps may not be
				considered mechanical feeding devices.

				one-sixteenth inch [1.59 millimeters] when there is no pressure in the boiler.
				The seats and disks must be of suitable material to resist corrosion.
c. A safety valve for a steam boiler may not
				be smaller than three-quarter inch [19.05 millimeters] unless the boiler and
				radiating surfaces consist of a self-contained unit. A safety valve may not be
				larger than four and one-half inches [114.3 millimeters]. The inlet opening
				must have an inside diameter equal to, or greater than, the seat
				diameter.

				capacity in pounds per hour is the greater of that determined by dividing the
				maximum British thermal units output at the boiler nozzle obtained by the
				firing of any fuel for which the unit is installed by one thousand, or is
				determined on the basis of the pounds of steam generated per hour per square

Current through Supplement No. 393, July, 2024
1. Each
				automatically fired hot water heating boiler must have an automatic low-water
				fuel cutoff that has been designed for hot water service and which can be
				tested without draining the system or the boiler. It must be so located as to
				automatically cut off the fuel supply prior to the surface of the water falling
				below the lowest safe water level as established by the boiler
				manufacturer.
2. A coil-type or
				watertube boiler requiring forced circulation to prevent overheating of the
				coils or tubes must have a flow-sensing device installed in the boiler or
				piping in lieu of the required low-water fuel cutoff that will cut off the fuel
				supply when the circulation flow is interrupted. Functioning of the low-water
				fuel cutoff due to a low-water condition must cause safety shutdown and
				lockout. Where a reset device is separate from the low-water fuel cutoff, a
				means must be provided to indicate actuation of the low-water fuel cutoff. The
				manual reset may be the instantaneous type or may include a time delay of not
				more than three minutes after the fuel has been cut off.
3. Low-water fuel cutoff requirements for
				steam boilers are addressed by section 33.1-14-03-07.
