Abegin with the end bolts and work toward the center
Bstart at the top and work down
Cbegin with the center bolts and work toward the ends
Dstart at the bottom and work up
AI Explanation
The correct answer is C) begin with the center bolts and work toward the ends. This is the correct procedure for reassembling a high-pressure boiler gauge glass in the absence of the manufacturer's instructions. The reasoning is that starting from the center and working outward helps to evenly distribute the pressure and prevent any warping or distortion of the gauge glass assembly. Beginning at the ends or working top-down or bottom-up could result in uneven tightening and potential leaks. The other options, while reasonable approaches, are not the optimal procedure recommended for high-pressure boiler gauge glass reassembly.
