Flexible fuel oil supply and return lines are supplied
with the unit, and connected to the oil burner. Lines
are terminated with 3/8-inch reverse flare fittings for

fuel oil tank. When connecting the lines, a 10-micron
Gerber oil filter must be installed in the oil supply line
to minimize burner contamination.
