Which action should be taken if the water level in the boiler gage glass drops out of sight and the burners fail to secure automatically?
AI Explanation
The correct answer is A) Trip the master solenoid.
If the water level in the boiler gage glass drops out of sight and the burners fail to secure automatically, the appropriate action is to trip the master solenoid. This will shut off the fuel supply to the burners, which is a critical safety measure when the water level is unknown or dangerously low. Tripping the master solenoid is the quickest way to secure the boiler and prevent potentially catastrophic damage or explosions.
The other options are incorrect because repairing the feed water regulator (B) or increasing the feed pump speed (C) would not address the immediate issue of the dropping water level. Blowing down the gage glass (D) would provide information but not resolve the underlying problem.
