GENERAL INSTRUCTIONS
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 regula-
tions relating to oil and combustion.
Only oil suitable for the burner should
be used and then in combination with

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 in accordance with the boiler
manufacturer´s instructions.These

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 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 follows: Increase the nozzle as-
sembly adjustment somewhat. The
CO2-content and consequently the air
volume will then be reduced.
Oil supply
The oil line should be dimensioned
in accordance with the pump
manufacturer´s instruction. In the

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 circula-
tion system should be used.
The temperature in the oil line should
be kept as constant as possible.Avoid
exposing the line to excessive cold

Air adjustment
First stage:
Set the operating switch (S2) on low
capacity (I). Loosen the screw (A)
and turn the damper to the position
wan-ted. Tighten the screw (A) again.
Second stage:
Set the operating switch (S2) on high
capacity (II). Screw the knurled ring
(B) in (reduce) or out (increase). The
position of the damper can be read
on the damper scale (C).

MAINTENANCE OF OIL BURNER
NOTE!
For maintenance of the brake plate, nozzles, electrodes etc, when using a
long design of the burner tube, you have to remove the nozzle assembly
from the connecting pipe and move the assembly backwards in the fan
housing (from the boiler).
Warning: Before doing any service switch off power at the main switch and cut off the oil supply.

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 valve and an

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.

lubricated during operation).

On 1-pipe systems it is necessary to
purge the pump. On 2-pipe systems
purging is automatic through the return

the nozzle line is effectively shut off.
If the pump is overloaded, i.e. more oil
is demanded than the gearwheel is
able to pump under the given condi-
tions, the oil pressure falls below the
set value because the piston of the
regulating valve moves towards its
closed position and partially or wholly
cuts off the return oil via port "O".
Two pipe systemMounting/dismounting by-pass plug
In a 2-pipe-system excess oil is
led back direct to the oil tank. In a
1-pipe-system the by-pass plug
must be removed so that there is
a free passage back to the suction
side through the return line with the
return port closed.

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.
