General rules
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
combustion.
Only oil suitable for the burner should
be used and then in combination with
of the burner.
If the burner is replacing an existing
is replaced or cleaned. The installa-
tion must only be undertaken by
experienced personnel. Care should
be taken by the installer to ensure
pipes are trapped or damaged during
Installation instructions
General installation instructions
accompany 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 in
accordance with boiler manufacturers
instructions.These must include the
average water temperature and CO2
or O2concentration.
To adjust the combustion device, start
by increasing the air volume and 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 disap-
pear again. Then the volume of air
is reduced until soot occurs and in-
creased again to reach a combustion
free of soot.
By this procedure an optimum
adjustment is obtained. If larger
nozzles are used the preadjustment
of both the air volume and the nozzle
assembly must be increased.
Awhistling sound may be heard which
can be eliminated or reduced as
follows: Increase the nozzle assembly
adjustmentsomewhat.TheCO2-content
and consequently the air volume will
then be reduced.

the oil from reaching the burner. If the
installation consists of several burners
each one should have its own suc-
tion line from the tank or a circulation
system 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

chimney. The risk increases if the area
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
them up during standstill)
Increase the oil quantity

Instructions for use
The end user of the burner should be
instructed about the operation and
safety features of the burner.
He should also be made aware of
the importance of the area around
combustible material.

AIR ADJUSTMENT WITH DAMPER MOTOR
The damper motor turns the damper
between 3 preset positions: fully
closed, low capacity and high capa-
city. These positions are controlled in
the motor by cams which are set by
means of the coloured disks. In ad-
dition there is a black disk controlling
the connection of solenoid valve 2.
If the air volume needs changing:
Remove the cover from the damper
motor and change the position of the
Low capacity:
Adjust the operating switch to high
capacity (II).
• Reduce the air volume:
Turn orange cam towards 0°.
• Increase the air volume:
Turn orange cam towards 90°.
Adjust the operating switch back to
low capacity and check.
Full capacity:
Adjust the operating switch to low
capacity (I).
• Reduce the air volume:
Turn red cam towards 0°.
• Increase the air volume:
Turn red cam towards 90°.
If the red cam is moved, change the
black cam as much. Adjust the opera-
ting switch back to high capacity and
ensure that the correct air volume has
been obtained.
Note!
The blue cam is the limit position for
fully closed damper and it is normally
not necessary to change it.
Releasing button
By pressing the button and snapping
it down, the motor will be released
and the damper can easily be turned.
This function facilitates an exchange
of damper motor.
MAINTENANCE OF OIL BURNER

Suction line tables
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
The sum of these individual resistances
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
tocurrentstandards.Oncommissioning
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 3,0 Gph. Max. permissible pressure
at the suction and pressure side is 2,0
bar. For two-pipe system Qmax
pump capacity at 0 bar.

Standard model
Solenoid valve
with cut-off
- Light oil.
- One or two-pipe system.
Pump operating principle
The oil pump has a built in solenoid
valve which controls the regulator
cut-off valve giving fast cut-off and
cut-on function independent of the
rotational speed.
The gear-set draws oil from the tank
it to the valve that regulates the oil
pressure to the nozzle line.
All oil which does not go through the
nozzle line will be dumped through
the valve back to the return line or, if
it is a one-pipe installation, back to the
suction port in the gear-set.
- Two-pipe operation
the by-pass channel between the
pressure and return sides of the valve
is open.
No pressure will then be built up to
open the valve. It does not matter
which speed the gear set has.
by-pass channel will be closed and
because of the full speed of the gear-
set, the pressure necessary to open
the valve will be built up very rapidly
which gives a very sharp cut-on
function.
- One-pipe operation
Bleeding on one-pipe is not automatic,
and a pressure port must be opened
to bleed the system.
Cut-off
opens the by-pass at the same moment
which drains all the oil down to the return
and the nozzle valve closes immediately.
This gives a very sharp cut-off function.
The cut-on and off can be regulated
regardless of motor speed and has
an extremely fast response.

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.
