How many gauge cocks are required on a boiler with less than 36 inches in height and 100 square feet of surface area?

The requirement for gauge cocks on a boiler is determined by safety standards and operational regulations. For a boiler that has a height of less than 36 inches and a surface area of less than 100 square feet, the regulation mandates the installation of two gauge cocks.

Having two gauge cocks is vital for ensuring accuracy in water level monitoring as one can serve as a backup and help to confirm that readings are consistent. This setup enhances safety by allowing operators to get a clearer understanding of the water level, thus minimizing risks related to low water conditions which can lead to boiler damage or failure.

For larger boilers or those that meet specific height or surface area criteria, additional gauge cocks may be required, but for this specific size and height, the established guideline is two. This regulation stems from best practices regarding the safe operation and monitoring of boiler systems.
