Question

Quizplus · Accepted Answer

When the fuel oil tank is located below the burner, a two-pipe system is necessary. This is because the fuel oil needs to be pumped from the tank to the burner and then the excess needs to be returned to the tank through a separate pipe. This helps to maintain a consistent fuel pressure and prevents the burner from running dry or flooding with fuel.
