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. On TWZ065 and TWZ075 boilers, the use of a Garber cartridge type filter is
recommended.
9) Use only #2 Fuel Oil with physical and chemical characteristics meeting the requirements of ASTM D-396.
