FIGURE 10.2: ONE-PIPE LIFT SYSTEM

7) Attach required piping between burner fuel pump and fuel oil storage tank. Install one fuel shut-off valve near the storage

tank and second fuel shut-off valve near the oil burner fuel pump. Use heavy wall copper tubing in a continuous run. On

two-pipe systems, the return line should terminate 3” - 4” above suction line depth within the storage tank. Refer to the

pump manufacturer’s instructions for tube sizing information.

8) All systems require an oil filter. For boilers having an input less than 1.00 GPH, the use of a Garber cartridge type filter is

recommended.
