AI Explanation
The correct answer is C) after you start the fuel oil service pump. When warming up a fuel oil service system, it is important to first start the fuel oil service pump to circulate the fuel oil through the system. This ensures that the fuel oil is being heated evenly throughout the system. Only after the pump is running should you open the steam supply to the fuel oil heaters. This allows the heated fuel oil to circulate and reach the appropriate temperature before the heaters are engaged. Opening the steam supply before starting the pump could result in uneven heating and damage to the system.
