AI Explanation
The correct answer is A) provide an alternate means of determining the water level, if the gage glass fails. Try-cocks are used on auxiliary boilers to provide a manual means of checking the water level in the boiler in case the primary water level indicator, the gage glass, fails. This allows the operator to maintain safe water levels in the boiler and prevent damage from low water conditions. The other answer choices do not accurately describe the primary purpose of try-cocks on an auxiliary boiler.
