The primary purpose of a fill line in an oil burner system is to fill the storage tank with oil. This line allows for the transfer of fuel oil from delivery trucks into the storage tank, ensuring that the system has a sufficient supply of fuel to operate efficiently. Proper filling procedures are essential to maintain the tank at an appropriate level and to prevent overfilling, which can lead to spills or leaks. Understanding the function of the fill line is critical in the operation and maintenance of oil burner systems, as it directly impacts fuel availability and system performance. This makes it an essential component in managing the overall efficiency of the heating system.
