How many gage cocks are required for a boiler not exceeding 36 inches in diameter and 100 square feet of heating surface?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

For a boiler not exceeding 36 inches in diameter and 100 square feet of heating surface, the requirement is to have two gage cocks. Gage cocks are essential for providing access to the boiler’s internal water level and pressure readings; they allow for the verification of the water level and help ensure safe operation. The code stipulates that a minimum of two gage cocks be installed to facilitate the accurate monitoring of water levels. This setup is particularly crucial because it allows operators to confirm the water condition from different points. In cases of malfunction or blockage at one gage cock, the alternate gage cock can still provide a reliable indication, enhancing safety and operational efficiency. In larger boilers or those designed for higher pressures, greater numbers of gage cocks might be necessary, but for the specified size and heating surface, two is both a sufficient and code-compliant requirement. This keeps the boiler's operation within safety standards while ensuring effective monitoring.
