5225.4200 WATER GAGE.

When the boiler operating pressure exceeds 100 pounds per square inch, the water gage glass must be fitted with either a gate-type or plug-type valved drain to a safe discharge point.

If the lowest water gage shutoff valve is more than seven feet above the floor or platform from which it is operated, the operating mechanism must indicate by its position whether the valve is opened or closed. Installation must meet the requirements of Section I of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code for high pressure boilers or Section IV for low pressure boilers.
