recirculated when connected to a two-pipe system. Size
two-pipe oil lines based on this flow rate.

• Use continuous lengths of heavy-wall copper tubing,
routed under the floor where possible. Do not attach fuel
lines to the appliance or to floor joists if possible. This will
p
reduce vibration and noise transmission problems.
• Install an oil filter sized to handle the fuel unit gearset flow
capacity ( Table 3
for the firing rate for
immediately adjacent to the burner fuel unit.
• Install two high-quality shut-off valves in accessible loca-
tions on the oil supply line. Locate one valve close to the
tank. Locate the other valve close to the burner, upstream
of the fuel filter.
