Section 7 - Fuel Supply Pump/ Piping
General Requirements - Fuel Tank
1. The fuel supply tank and supply lines must be installed in accordance with the National Fire Protection Association
requirements, as well as state and local ordinances.
2. Regulations require oil storage tanks located inside a building not exceed 275 gallons individually and are not to
exceed 550 gallons in one building. Check state and local codes.
3. Oil storage tank must be inside the building as close to the boiler as possible (max. 25 feet) to avoid flow problems.
4. Pitch the fuel supply 2º with the drain valve at the lowest end to drain off water and sludge. Sludge may have to
manually be removed.
5. Some ordinances may require the fuel supply tank to be vented to outside, and above the roofline. Check State and
Local codes. Keep the vent clear.
6. Install the fuel tank fill pipe at the end of the tank and above the drain.
7. Label the fuel tank for the recommended fuels.
8. Strain all fuel with a 50 X 50 mesh strainer before putting fuel into the tank.
9. When filling the fuel tank with a motorized pump, never leave unattended to prevent over filling and/or spillage.
10. Keep fill cap on the fuel tank when not filling.
General Requirements - Fuel Pump/Piping
1. Mount the fuel supply pump in a horizontal position (shaft horizontal) near the fuel supply tank.
2. The oil pump has a maximum suction lift of 14 feet. Suction lift is the length of pipe run from the bottom of the
pick up strainer to the fuel supply pump.
3. The fuel pump/motor are for indoor use only.
4. The fuel pump contains an internal strainer that periodically needs to be cleaned (see Section 18, page 33). This
internal strainer is mounted behind the pump cover. Before removing the pump cover make sure you have a new
gasket on hand. Contact the Lanair Customer Service Department for the proper gasket for your model of pump, at
800-753-1601.
5. Install the suction supply line from the inlet side of the fuel pump into the fuel tank opposite the drain.
6. Install a 1/2” inside diameter (.493) steel pipe, or 1/2” outside diameter copper throughout the suction supply line
and pick up tube. The use of smaller line, or rubber, plastic or hydraulic line is unsafe and will void your warranty.
7. Use thread sealing compound on all pipe thread connections. DO NOT USE TEFLON TAPE.
8. Install the suction line strainer in the suction line. Make sure the suction line strainer is 6” off the bottom of the tank.
The suction line strainer may be mounted horizontally or vertically. Consider accessibility.
9. Install a pipe union between the suction line strainer and the pick up tube to allow for service on the pick up tube.
