Oil Supply
6 Oil Pump
The pump is supplied and set as standard (unless specied
otherwise) as a one pipe conguration.
In order to obtain a two pipe conguration it is necessary
to remove the horseshoe washer from the BFP11 oil pump
(See Fig. 11). Aer removal, an additional oil exible will
have to be tted yo the return port (additional oil exible
not supplied).

Where gas oil containing biodiesel is in use, it is
recommended to avoid over oxygenation of the
blended fuels.
Where at all possible avoid the use of two pipe
systems where the circulated fuel is returned to the
tank. If this cannot be avoided make sure that the
return pipe is normally below the surface of the fuel
level within the storage tank. See B) Fig. 13.
The plug in the return line (R) must be a metal
bung.
In case of use with gas oil containing up to 10%
bio blend, it will be essential to use exible oil lines
suitable for biofuel use.
Please contact EOGB for further information.

1 pipe system
To prime the oil pump, loosen the port plug of the vacuum
gauge port V)(Fig. 12). Run the burner and wait until the
fuel ows out.
2 pipe system /
1 Pipe Suction Li With De-Aerator
To prime the oil pump, loosen the port plug of the pressure
gauge port P)(Fig. 12). Run the burner and wait until the
fuel ows out. Should a lock-out occur prior to the arrival of
the fuel, tighten the port plug to prevent air re-entering the
pump, and wait at least 30 seconds before repeating the
operation.
or
With the aid of an oil priming suction pump, attach and pull
the oil through the vacuum gauge port V)(Fig. 12)
In a 2 pipe operation before starting the burner,
make sure that the return pipeline is not clogged/
obstructed and the oil pump is congured cor-
rectly as if not, then the pump sha seal will break
due to overpressure (not covered by
manufacturer’s warranty).
The pump vacuum should not exceed a
maximum of 0.4 bar (30 cm Hg).
Beyond this limit, gas is released from the oil.

WARNING
In a 1 pipe system or a pressurised system, the
installer must ensure that the supply pressure is not
above 2 bar. Above that level, the pump seal is
subject to too much stress.
