condensate, which causes the tank to rust. It is also recommended to use a water trap or additives
to prevent condensate accumulation.
If the tank is above the burner, and gravity oil feed to the burner is permitted, a single line system
may be used. The line should have a gradual slope downward of approximately 1/2 inch per foot,
or more, to a point directly below where it is connected to the pump. Installing the line with a
downward slope will help prevent the formation of air pockets in the line.
IMPORTANT: An oil safety valve or a delayed-action solenoid valve is required with all
gravity feed oil supply systems.
IMPORTANT: The oil storage tank must be free of water, sludge and scale to prevent
excessive wear and possible damage to furnace oil pump and burner nozzle. A fuel oil filter
installed in the oil supply line to the burner is required.
OIL FILTER: For all installations, use a low micron, oil filter with the capacity to trap particles
10 microns in diameter, or greater. Filtering the oil supply helps to prevent nozzle clogging.
Install the oil filter inside the building between the tank shutoff valve and the burner. The filter
cartridge should be replaced at least once a year. The filter body should be thoroughly cleaned
before installing a new cartridge.
