GENERAL INSTRUCTIONS
GENERALRULES
The installation of an oil burner should
be carried out in accordance with local
regulations. The installer of the burner
must therefore be aware of all
regulations relating to oil and combu-
stion.
Only oil suitable for the burner should
be used and then in combination with
a suitable oil filter before the oil pump
of the burner.
If the burner is replacing an existing
burner make sure that the oil filter is
replaced or cleaned. The installation
must only be undertaken by experien-
ced personnel. Care should be taken
by the installer to ensure that no
electrical cables or fuel/gas pipes are
trapped or damaged during installation
or service/maintenance.
INSTALLATION INSTRUCTIONS
General installation instructions ac-
company the burner and should be left
in a prominent place adjacent to the
burner.
ADJUSTMENT OF BURNER
The burner is from the factory pre-set to
an average value that must then be
adjusted to the boiler in question.
All burner adjustments must be made
inaccordance with boiler manufacturers
instructions.These must include the
checking of flue gas temperatures,
average water temperature and CO2or
O2concentration.
To adjust the combustion device, start
by increasing the air volume and the
nozzle assembly somewhat.When the
burner starts it is burning with excess
air and smoke number 0. Reduce the
nozzle assembly adjustment until soot
occurs, and then increase the
adjustment to make the soot disappear
again. Then the volume of air is reduced
until soot occurs and increased again
to reach a combustion free of soot.
By this procedure an optimum adjust-
ment is obtained. If larger nozzles are
used the preadjustment of both the air
volume and the nozzle assembly must
be increased.
A whistling sound may be heard which
can be eliminated or reduced as fol-
lows: Increase the nozzle assembly
adjustment somewhat. The CO2-con-
tent and consequently the air volume
will then be reduced.
CONDENSATION IN CHIMNEY
A modern burner works with less ex-
cess air and often also with smaller
nozzles than older models.
This increases the efficiency but also
the risk of condensation in the chimney.
The risk increases if the area of the
chimney flue is too large. The tempera-
ture of the flue gases should exceed
60°C measured 0,5 metres from the
chimney top.
Measures to raise the temperature:
Insulate the chimney in cold attics
Install a tube in the chimney
Install a draught regulator (dilutes the
flue gases during operation and dries
them up during standstill)
Increase the oil quantity
Raise the flue gas temperature by
removing turbulators, if any, in the
boiler.

MAINTENANCE
The boiler/burner should be examined
regularly for any signs of malfunction
or oil leakage.
OIL SUPPLY
The oil line should be dimensioned in
accordance with the pump manu-
facturer´s instruction. In the suction
line to the burner a filter should be
mounted to prevent any particles in the
oil from reaching the burner. If the
installation consists of several burners
each one should have its own suction
line from the tank or a circulation sy-
stem should be used.
The temperature in the oil line should
be kept as constant as possible. Avoid
exposing the line to excessive cold
which may cause blockages of paraffin
deposits.
The oil pipe and electric cable should
be fitted so that the burner can be
placed on the floor for inspection of the
combustion device.

transformer is connected to terminal 7 (LOA24.173...).
3. The safety time expires
a. If no flame is established before this time limit the control cuts out.
b. If for some reasons the flame disappears after this time limit, the
burner will make an attempt to re-start.
3-4. Operating position
If the burner operation is interrupted by means of the main switch or the
thermostat, a new start takes place when the conditions in accordance
with point 1 are fulfilled.
The oil burner control cuts out
A red lamp in the control is lit. Press the reset button and the burner
re-starts.
Post-ignition
(2) If a post-ignition of 15 s. is wanted, move the ignition transformer from
terminal 7 to terminal 6 (LOA24.173...).

SUCTIONLINETABLES
The suction line tables consist of
theoretically calculated values where
the pipe dimensions and oil velocity
have been matched so that turbulences
will not occur. Such turbulences will
result in increased pressure losses and
in acoustic noise in the pipe system. In
addition to drawn copper piping a pipe
system usually comprises 4 elbows, a
non-return valve, a cut-off valve and an
external oil filter.
The sum of these individual resistances
is so insignificant that they can be
disregarded. The tables do not include
any lengths exceeding 100 m as
experience shows that longer lengths
are not needed.
The tables apply to a standard fuel oil of
normal commercial quality according to
current standards. On commissioning
with an empty tube system the oil pump
should not be run without oil for more
than 5 min. (a condition is that the pump
is being lubricated during operation).
The tables state the total suction line
length in metres at a nozzle capacity of
10,0 kg/h. Max. permissible pressure at
the suction and pressure side is 2,0 bar.
PURGING
On 1-pipe systems it is necessary to
purge the pump. On 2-pipe systems
purging is automatic through the return
line.
With an underlying tank a 1-pipe-
system is not recommended

FUNCTION DANFOSS BFP 21 L5
When the oil pump is started, oil is
drawn from the suction connection (S)
through the filter (H) to the suction side
of the gear wheel (C).
The gear wheel then pumps oil to the
pressure side and the oil is put under
pressure.
The pressure is controlled and kept
constant at the set value by the
regulatingvalve(P1)with the diaphragm
(D).
The regulating valve (P1) distributes
the oil quantity supplied by the gear set
(C) between the nozzle port (E) and
the return side of the pump (R).
The oil quantity utilized is determined
by the set pressure on the regulating
valve (P1) and the size of the oil nozzle
in the nozzle line.
The valve (P1) functions in the following
way:
- Whentheopeningpressurehasbeen
reached, the passage to the return
side opens.
against the return side (R) by means
of the diaphragm (D) and goes into
starting position.
This can be remedied by:
- Reducing the pump pressure.
- Reducing the oil quantity supplied
by using a smaller nozzle.
- Using a pump with a larger capacity.
- The diaphragm and the spring keep
the pump pressure constant at set
value.
- If the pump is overloaded, i.e. if you
try to get out more oil than the gear
set can supply under existing circum-
stances, the oil pressure falls below
the set value and the valve closes
REPLACEMENT OF CARTRIDGE
FILTER
HOW TO REMOVE CARTRIDGE
FILTER FROM PLUG
Unscrew the cartridge filter plug in the
cover by means of a 4 mm allen key
and withdraw the cartridge filter. If
necessary, put a screwdriver between
the cartridge filter and the plug and
turn the cartridge filter carefully until it
comes off. Reject the cartridge filter
and replace it by a new one. Press it
on to the plug. Ensure that the O-ring
is not damaged. Then fit the new
cartridge filter to the pump.

OIL BURNERS MAINTENANCE
INSTRUCTIONS
General information
Keep the boiler room clean. Ensure that the boiler
room has permanent fresh air intake. Switch off before
dismantling the oil burner.
At hinged mounting, make sure that an automatic safety
switch is fitted, so that the burner cannot start when
theswing door is open.
Don´t use the oil fired boiler to burn paper or
rubbish,unless the boiler is especially fitted with a hinged
door tomake this possible.
Don´t fill tank while burner is working.
Starting precautions
Make sure that the oil tank is not empty
Make sure that the valves on oil and water supply pipes
areopen.
Make sure that the boiler flue damper is open.
Make sure that the boiler thermostat is set at the correct
temperature.
Switch on the current. Most relay systems have a
delayed action so that the burner will not start for
perhaps 20 seconds.
With heavy oil the delay will be longer as the burner
will notstart until the oil in the preheater reaches the
requiredtemperature.
If the burner will not start
Press the reset button on the relay. Check that the
thermostats are correctly adjusted.
Don´t forget the room thermostat, check that any
fusesare intact and main switch is on.
If the burner starts but does not ignite
Make an attempt to start the burner.
Never make close repeated start attempts.
Don´t restart the burner until the boiler is free from oil
gases.
If the burner still does not ignite send for the service
engineer.
When switching off during summer
Always use the main switch to cut out the burner even
when adjusting the burner or cutting off the heating for
ashort time. For longer periods of shut down, close all
valves and the oil supply stop-cock.
Clean the filter and nozzle by washing in petrol or
paraffin.
Make sure the filter medium is not damaged or defective.
Protect electrical gear from damp.
Warning
Never stand too near or put your face to the inspection
or fire door, when the burner is about to start.
Never use a naked flame to ignite oil if the electrical
ignition fails.
Always wait for about 10 minutes for the unburnt gases
to disperse before restarting the oil burner if it has failed
to ignite previously.
