pump self priming even when the tank is almost completely empty. See
Figure 16.
11. The tank is lower than the pumping unit (B): Pump suction pressures higher
than 13"Hg for Suntec oil pump must not be exceeded. This is because
at higher levels, gas is released from the fuel and the pump starts making
noise and its working life-span decreases. See Figure 16.
12. It's good practice to ensure that the return and suction lines enter the
pump from the same height to reduce risk that that the suction line fails to
prime or stops priming.
13. Consult a qualified professional for assistance in designing and installing
oil delivery systems. See Figures 16 and 17.

Multiple Burner Installations

For installations with multiple Vantage dual fuel boilers sharing common supply
and return oil piping, it is recommended to use a "flooded loop". See Figure 17.
Adhere to the following:
1. Constant pressure must be maintained at each burner pump regardless
of the number of burners operating. This arrangement generally requires
auxiliary oil pumps, a pressure relief valve, and a back pressure regulator.
These devices are not provided with the boiler.
2. Auxiliary oil pumps run continuously during oil operation, and are typically
each sized for 1-1/2 times the total supply flow rate of all burner pumps.
See Table 4.
3. A pressure relief valve is installed on the discharge side of the auxiliary oil
pumps for the purpose of protecting the pumps and serves no regulatory
function.
4. A back pressure regulator is located after the supply pipes to each burner
pump and before the return pipes from each burner pump, with the
purpose of maintaining a pressure against the suction side of the burner
pumps, not to exceed 3 PSI.

Hydraulic Connections

Adhere to the following for hydraulic connections:
1. The oil pumps are equipped with a bypass that separates the return line
and suction line. The pumps are installed on the pumping unit with the
bypass closed. It is necessary to connect both hoses to the pump.
2. Damage to the pump seal will occur immediately if it is run with the return
line closed and the bypass screw inserted.

fuel oil. Failure to maintain this will
void the warranty.
