Generated explanation

The illustration shows a basement oil tank connected to an oil furnace by separate supply and return fuel lines routed overhead. Arrows indicate fuel flowing toward the burner through the supply line and back toward the tank through the return line. A Firematic valve and filter are shown in the supply piping near the burner, while an optional check valve is identified on the return line. An annotation explains that the Firematic valve shuts off fuel if there is a fire. The drawing also shows the tank's exterior fill and vent piping, foundation wall, and floor framing above.
