• There are fewer temperature changes, which means the oil will last longer. • If a leak develops, it will cause an odor, which quickly alerts us to the problem. • It’s easier to inspect. • Less condensation in the tank. It is important that you follow codes and instructions regarding: A. Distance from the tank to the burner (At least 5 feet.) B. Size and height of the vent pipe C. Size of the fill pipe D. Fusible valve at the tank E. Fusible valve at the burner In addition: 1. The fill and vent lines must be pitched toward the tank Chapter 3 Oil Tanks and Piping 3-6 Oil Tanks and Piping 2. All tanks should have a vent alarm 3. All tanks should have a tank gauge 4. All systems should have an oil filter; it can be located at the tank, at the burner or at both the tank and burner. 5. The copper oil line from the tank to the burner (shown here running under the floor) should not touch concrete or soil. This can be done by sliding the copper oil lines into plastic conduit or plastic pipe or by using a coated copper line. There should be no fittings in the copper lines below the floor. Figure 3-4. Above-ground outside tanks If there is no room for a tank inside the building, it must be installed outside, see Figure 3-5.
