Please note:
The oil pressure is preset at the factory according to the oil throughput.
Adjust the oil pressure, if necessary.
1. Isolate the mains electricity
supply and safeguard against
reconnection.
2. Unscrew drain plug "P" A from
the oil pump.
3. Unscrew drain plug "V" B from
the oil pump.
4. Insert a pressure gauge (range
0 25 bar) and a vacuum gauge
(range 0 1 bar); seal the gauges
only with copper or aluminium
rings or O−rings.
5. Start up the burner.
6. Read off the oil and vacuum
pressures of the pump on the
relevant gauges (vacuum should
be max. 0.35 bar given a head of
3 m between the oil pump and
the bottom of the tank).
7. If necessary, set the oil pressure
on oil pump pressure setting
screw C (for Danfoss pumps:
depending on the model either on
the front or the side).
Turning clockwise ³ pressure

Turning anti−clockwise ³ pressure
decreases.
8. Check the emission values after

9. Isolate the mains electricity
supply and safeguard against
reconnection.
10. Remove the pressure and
vacuum gauges.
11. Insert drain plugs "P" A
and "V" B.
12. Start up the burner and
check the plugs for leaks.
Please note:
This allows the oil to drain from
the oil pump.
Please note:
Do not use tape to seal these
joints.
The solenoid valve opens.
Where the vacuum measures
higher than 0.35 bar, check the
filter for cleanliness or the pipe
run.
Please note:
For standard values for burner
settings, see page 22.
Please note:
Check the plug seal rings
for possible damage and replace,
if necessary.
