AI Explanation
A is the correct answer. When a boiler economizer is fitted with a valved bypass, Coast Guard Regulations require that the bypass be kept open until the boiler is brought up to operating temperature. This ensures the boiler is not damaged by cold feedwater flowing through the economizer before the system is properly heated. The other answer choices are incorrect because they do not accurately reflect the Coast Guard requirement to keep the economizer bypass open during boiler startup.
