Once the type of system has been selected, observe the following:

1)Fuel line piping must be airtight. Do not use compression type fittings for tubing connections in fuel line piping. Use only listed flare type fittings. Cast iron threaded fittings shall not be used for wrought iron or steel piping connections.

2)Piping shall be substantially supported and protected against physical damage and corrosion where required.

3)Refer to supplied oil pump instruction manual for proper connections. On one-pipe systems, ensure that the fuel pump return port plug is tightened securely.

4)Some fuel pumps, such as the Suntec A and B series, are supplied with a loose bypass plug which must be installed on two-pipe systems. If such a plug is supplied, install it as shown in the pump manufacturers’s instructions. Do not install this bypass plug on one-pipe systems as pump seal damage will result.

5)Do not use check valves, especially on gravity feed systems.

6)Do not use Teflon tape for threaded connections. Use a listed non-hardening thread sealant instead.

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 KSZ065 and KSZ075 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.
