According to 46 CFR regulations pertaining to tests and inspections as related to automatic auxiliary boilers, the draft limit control must be checked for proper operation. What statement is true?

AI Explanation
The correct answer is C. According to 46 CFR regulations, the draft loss interlock switch must be tested to ensure that a safety shutdown occurs and boiler startup is prevented when there is insufficient draft to support combustion. This is a regulatory requirement to verify the proper operation of the draft limit control system, which is a critical safety feature for automatic auxiliary boilers. The other answer choices are incorrect because they either do not require testing both the safety shutdown and startup prevention functions (A and D), or they only require testing one of the functions (B).
