system, the pump draws fuel from the tank, then

pushes it through the installation under pressure.

The pressure is controlled at the pump by a

pressure relief valve at approximately 0.8 BAR (12

psi). When a pressurised system is used, a pressure

reducing valve set at approximately 0.3 BAR (5 psi)

should be installed on the fuel inlet to each heater

after the manual isolating valve. This protects the oil

pump from the danger of possible over pressure

under fault conditions.

The electrical supply for the pump installation will

depend upon the type of pumps chosen, but will

normally be set to run continuously.
