If pump has been drained, fi ll it with fuel through
the opening on the vacuum meter prior to starting;
otherwise the pump will seize.
3. For self-priming to take place, one of the screws of the
pump must be loosened in order to bleed off the air
contained in the suction line.
4. Whenever the length of the suction piping exceeds 66-
98 ft (20-29.8 m), the supply line must be fi lled using a
separate pump.
Oil Filtration
The oil supply to the Vantage boiler should be fi ltered and
be free of debris. Regular maintenance of the fi lter is re-
quired (as per the fi lter manufacturer’s recommendations)
to maintain the Vantage warranty. It is the responsibility of
the installing contractor to provide adequate fi ltration for
the oil supply system.
Venting
Adhere to the following venting requirements:
1. The Vantage boiler can operate to the combined intake
and fl ue pressure drops without altering standard
capacities: See Table 4.
2. The pressure drop readings at the boiler exhaust
connection and air intake connection cannot exceed
the maximum value stated in Table 4. This means that
the combined pressure drop through the air intake
venting (if installed) and exhaust venting cannot
exceed the maximum value stated in Table 4; this is
typically approximately 35 feet (10.6 m) and 4 elbows
of connection size piping. If exceeded, the boiler will
have to be de-rated or operational issues will result.
Also, the pressure at the boiler exhaust connection
must not exceed a maximum negative value as stated
in the table. This pressure must remain relatively
constant throughout the operation of the boiler.
Drastic draft changes during operation may result in
generation of excessive carbon monoxide or soot. To
decrease termination noise, increase the venting size
at the termination points. This will slow the air velocity
causing a reduction in noise. Do not terminate the
venting in an enclosed area. Care must be taken when
selecting the orientation of the terminations.
or acceptable alternate. See Figure 7. No settings are
required for the pump, which is set to 198-200 PSI
(1365-1379 kPa) by the manufacturer. This pressure
must be checked and adjusted (if required) after the
burner has been ignited. There is a pressure gauge
provided with the oil pump assembly on the boiler so
pressure can be monitored.
6. The oil piping system should be a 2-pipe system. The
delivery rate of oil to the boiler will be greater than the
fuel consumption rate of the boiler. The oil that is not
consumed should be returned to storage. Consult a
qualifi ed professional for assistance in designing and
installing oil delivery systems. See Figure 10.
7. Fuel Supply: The pumping unit of the burner is
equipped with a self-priming pump, which is capable
of feeding itself within the limits listed in the table in
Figure 9.
8. It’s good practice to ensure that the return and suction
lines enter the pump from the same height; in this way
it will be more improbable that the suction line fails to
prime or stops priming.
Hydraulic Connections
Adhere to the following for hydraulic connections:
1. The oil pumps are equipped with a by-pass that
separates the return line and suction line. The pumps
are installed on the pumping unit with the by-pass
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 by-pass screw
inserted.
Oil Pump Priming
Adhere to the following for pump priming:
1. Before starting the burner, make sure that the tank
return line is not clogged. Obstructions in the line could
cause damage to the pump seal.
2. The pump leaves the factory with the by-pass closed.
Check to make sure that the valves located on the
suction line are open and that there is suffi
cient fuel
in the tank. Priming operation is possible because the
pump is already full of fuel when it leaves the factory.
