Burner description
MAIOR PRE burners are progressive
electronic fully automatic monoblock
devices. Burner head is designed to get
the lowest emissions in terms of NOx and
unburnt particles in order to maximize the
heat generator efficiency. Emissions can
be different respect to the ones recorded in
the lab because they depends a lot on the
generator on which the burner is fit.
The installer must comply with compulsory
rules. Avoid for instance dangerous
atmosphere or not ventilated rooms.
Packaging and handling
Move the burner still in its packaging using
a trolley or forklift, taking care not to drop it
and elevating it no more than 20cm from
ground level. After having removed the
packaging, check that the contents are in
good condition and correspond with what
was ordered. If in doubt, contact the
manufacturer.
The burner must be installed by a
qualified individual.
If the weight and dimensions do not allow
for manual lifting, ask another operator for
help or use a forklift, harness the burner
using belts if no eyebolts are available.
Use the accessories provided
(flange, gasket, pins and nuts) to
install the burner onto the boiler,
taking care not to damage the isolating
gasket.
We can accept no warranty liability
whatsoever for loss, damage or injury
caused by any of the following:
- Inappropriate use.
- Incorrect assembly or repair by the
customer or any third party, including the

WORKING DIAGRAMS
TEST BOILER  FLAME DIMENSIONS
The burner/boiler matching does not pose
any problem if the boiler is CE type-
approved.
If the burner must be combined with a
boiler that has not been CE type-approved
and/or its combustion chamber dimensions
are clearly smaller than those indicated in
diagram, consult the manufacturer.
The firing rates were set in relation to
special test boilers, according to EN 267
regulations.
The sizes are indicative and dipend on
the configuration, to the combustion
chamber pressure and to the draught.
The values have been taken out from
tests executed with flame tubes.
The dimensions of the flame are made
in test boiler in laboratory without
resistence therefore exists max and
min lenght that take into account the
difference in lenght that comes from the
boiler backpressure.
Example:
Burner thermal output = 8000 kW;
L flame (m) = 5 m (medium value)
D flame (m) = 1 m (medium value)
WARNING: Some flame modifications
can be done in our FLEXSHOP in the
factory in order to shape the flame and
adapt it to some special boiler
or application.

OIL OPERATING MODE  GENERAL SAFETY FUNCTIONS
GENERAL SAFETY FUNCTIONS
In case a flame does not develop when
starting the burner (fuel release) the
burner will shut off at the end of the safety
period (safety lock-out).
A safety lock-out will also occur in the case
of flame failure during operation, air flow
failure during the pre-ventilation phase and
pressure failure during the whole period of
burner operation.
Any failure of the flame signal at the end of
the safety period and a flame signal during
the pre-ventilation phase (external light
control) will result in a safety lock-out with
the control box being locked.
The trouble is indicated by the trouble
signal lamp lighting up.
The control box can be unlocked
immediately after a safety lock-out by
pressing the unlocking key. The program
unit will return to its starting position and
proceed with the restart of the burner.
A voltage failure will result in a regular
shut-off of the burner. Upon voltage
recovery there may be an automatic
restart unless another interlock is
provided, e.g. by the safety system. In any
case of trouble the fuel oil supply will be
shut off right away. The program unit will
stop at the same time causing also the
trouble location indicator to stop.
The symbols will indicate the kind of
trouble.
STARTUP MODE
As soon as the furnace system is required
to supply heat the burner control circuit will
close and the program be started. After the
program has run down the burner will start.
The air damper is closed when the burner
iis out of operation.
The automatic furnace controller controls
and monitors the starting function.
The electric actuator opens the closed air
damper to its full-load position so that the
burner will sweep the furnace
compartment and exhaust ports at the
required air flow rates. Shortly after the
pre-ventilation process has been started
the lack-of-air cut-out must change over to
operating position within a certain time, i.e.
the minimum air pressure setting must be
reached and maintained until the burner is
turned off. At the end of the specified pre-
ventilation time the air damper will be
moved into its partial load position. This
operation will be followed by the pre-
ignition procedure and the oil feed start.
The solenoid valves will open and thus
allow the pressurized oil to flow to the
nozzle and to the return line.
The oil will be atomized, mixed with the
combustion air and ignited.
A safety period is provided to allow the
flame to develop a proper and steady
pattern.
On the termination of the safety period, a
flame signal must have been received by
the automatic furnace controller via the
flame monitor and remain on until the
regular shut-off.
The startup program of the burner has now
been completed.
OIL OPERATING MODE
After the flame has developed the load
regulator will be enabled which brings the
burner into its operating position.
The load regulator will now control the
burner automatically between its partial-
load and full-load stages.
Depending on the heat demand, the
electric actuator of the mechanical
compound control system will be fed with
the OPEN or CLOSE signal via the
regulator and thus increase or decrease
the oil and air flow rates.
This compound control system will vary
the positions of the oil control valve and air
damper and thus regulate the oil flow rate
in conjunction with the air flow rate. The
burner can either be controlled in two-
stage sliding mode or, if a respective
controller is provided, in stepless control
mode.
The stepless control will allow the burner
to be operated at any desired stage
between its partial-load and full-load
positions. The burner will be turned off
from its partial-load position. The air
damper will be closed when the burner is
out of operation and will thus prevent cold
air flowing through the burner chamber,
heat exchanger and chimney.
The interior cooling losses will be greatly
minimized.

BURNER LINING
Check before burner installation:
1. Depending on the type of boiler (reverse flame or three
pass) check the burner blast tube installation depth
according to the data specified by the boiler manufacturer or
consult the burner producer.
2. From the factory the nozzle for progressive version must
be specified from the customer according to boiler output and
combustion chamber geometry, otherwise we will select the
nozzle for the 80% capacity of the burner.
3. Check the ignition electrodes and the nozzle on the burner
head as per factory setting (see figures).
The setting of the mixing and ignition unit according to the
boiler output will be performed during commissioning
procedure.
4. Check that the head is preset at 50%.
A
A1
To perform the installation of the burner
into the boiler drill the boiler plate
according to the dimension given on this
manual and place the burner towards it by
lifting and moving the burner by means of
eyebolts.
Place the gasket on the burner flange and
install the burner into the boiler by fixing
nuts into the bolts.
The space between the blast tube and the
boiler lining must be sealed with
appropriate insulating material.
Burner blast tube insertion depth and
brickwork
Unless otherwise specified by the boiler
manufacturer, heat generators without a
cooled front wall require brickwork or
insulation 5 as shown in the illustration.
The brickwork must not protrude beyond
the leading edge of the blast tube, and
should have a minimum conical angle of
60°. Gap 6 must be filled with an elastic,
non-combustible insulation material. For
boilers with reverse firing, the minimum
burner tube insertion depth A as specified
in the boiler manufacturer’s instructions
must be observed.
On boilers the blast tube insertion depth
should be observed as per the boiler
manufacturer's instructions.
Reverse flame boiler :
A = 50-100 mm.
Three pass boilers :
A1 = 50-100 mm.
Exhaust system
To avoid unfavourable noise emissions,
right-angled connectors should not be
used on the flue gas side of the boiler.

!WARNING: make sure that the feeding line is properly dimensioned and is in compliance with the local safety rules and code of practise in
the country of installation
INSTALLATION
Oil connection
OIL PRESSURE CONTROL (FEED)
The feed pressure is controlled by means
of the pressure regulator installed in the
pump and should be set at 25 bar. The
pressure regulator is operated by turning
its screw. Make sure to fill the pump with
oil prior to taking into operation.
PUMP BLEEDING
Open the feed and return stop valves and
ensure the ring line (if any) is in operation.
Reduce the oil pressure at the pressure
regulating valve. Turn on the pump by
pressing the contactor.
Check the pump for proper direction of
rotation. Check for proper oil delivery and
absence of leaks in the hydraulic oil
system. For bleeding the pump open the
pressure gauge connection, for example.
When taking the burner into operation pro
ceed by gradually increasing the pressure
to operating level (25 bar).
CHECKING THE PRESSURE
(OIL SUCTION PRESSURE)
The maximum permissible vacuum is 0,4
bar. At higher vacuum levels the fuel oil will
tend to separate air from oil which may
lead to operating trouble. In the ring line
mode of operation the recommended oil
pressure is 2 bar.
OIL CONNECTION
Hoses are used for connection to the oil
lines and stop valves. The hoses must be
installed according to the applicable
standards (relieved of tensile load, free of
distortion) to avoid kinking and exclude the
danger of breakage. Take care when
mounting the oil lines to bring their ends as
close to the burners as possible and to
arrange them in a way that the boiler door
and the burner can be swing out without
any obstruction.
Refer to the technical documentation for
the line dimensions for the feed and return
lines from the stop valves to the tank.
OIL FILTER
A filter must be installed upstream of the
pump to protect the oil pressure pump and
the hydraulic system.
INSTALLATION OPTIONS
• Two-line installation (separate feed and
return lines without delivery pump).
• Ring line system (with delivery pump and
gas-air separator).

INSTALLATION
The pumps that are used can be installed both into singlepipe and
doublepipe systems:
Single-pipe system: a single pipe drives the oil from the tank to the pump’s
inlet that deliver the pressurized oil to the nozzle and part of the oil not used
goes back to the pump. With this single pipe the by-pass plug must be
removed and the return port must be sealed with steel plug and washer.
Double-pipe system: this is the default solution from the factory.
The return pipe send the excess oil from the pump to the tank. Depending
on the type of pump used to change from a 1-pipe system to a 2-pipe-
system, insert the by-pass plug (as for ccw-rotation referring to the pump
shaft).
Note for commissioning: during commissioning, the filter, pipelines and
pumps must be pre-filled with fuel oil and vented.
The direction of rotation of the motor should be checked. When
commissioning it must be ensured that pump never run dry.

The burner is equipped with a self-priming pump which is capable of feeding
itself within the limits listed in the table at the side.
• Two-pipe lift system
WARNING: To calculate the length of the pipework all the straight parts, curves, up and down pipes must be taken into consideration.
The static suction height is the distance between the standing valve and the axis of the burner pump.
Negative pressure must not exceed 0,45 bar; if negative pressure is greater pump operation may become faulty, leading to an increase
in mechanical noise and perhaps even breakage.

EXHAUST GAS TEST
To ensure an economically efficient and
trouble-free operation of the system it will
be necessary to adjust the burner
specifically in accordance with the furnace
system. This is achieved by means of a
fuel-combustion air compound control unit
which adjusts the burner to ensure a
proper combustion. Exhaust gas tests are
required for this purpose.
The percentage CO2 and O2 and the
exhaust gas temperature will have to be
measured to determine the efficiency and
combustion quality.
Prior to any measurement make sure to
check the boiler and exhaust gas system
for absence of leaks.
Recommended combustion parameters
Ratio between O2- and CO2-
for natural gas H (CO2max = 11,7%)
Ratio between O2- and CO2-
for light oil EL (CO2max = 15,40%)
Ratio between O2- and CO2-
for heavy oil S (CO2max = 15,60%)
O2= 21 CO2max - CO2gem = %
CO2max
WARNING: if the installation is above sea level the output of the burner
vary base on the diagram.
The regulation of the burner in this case shall take into account the
reduced power of the burner due to the missing air.

STARTUP OIL SIDE
Select the oil operation in order to proceed with start up on the oil side.
START UP THE BURNER
The control box starts the pre-purge cycle, the fan motor and the oil motor and opens the air flaps in full open positon.
At the end of pre-purging, the control box drives the servomotors into the igniton positon and starts the igniton transformer.
After a few seconds the control box opens the oil valve and starts the flame. After the flame stabilisaton the control box drives the
servomotor in the low flame.
In case of faulty igniton, the control box switches the burner into safety condition, in such a case you must rearm the burner.
Gradually increase burner output from the low flame to the high flame and set oil servomotor curve in order to have
a stable flame. Refer to LAMTEC manual attacched.
Firing head setting
The firing head is pre-adjusted at the 50% from the factory. The
setting fully open enables to reach the full power of the burner
and full close to reach the minimum power of the burner.
The optimal position depends on the output that we need to
reach but the default setting shall be modified only when you are
not able to reach the suggested combustion value by adjusting
the air flow in the maximum flame.

Adjusting the pump pressure
The pump pressure is set at a value of 22-25 bar during the testing of burners. Before
starting the burner, bleed the air in the pump through the gauge port. Fill the piping with
light oil to facilitate the pump priming. Start the burner and check the pump feeding
pressure. In case the pump priming does not take place during the first pre-purging, with
a consequent, subsequent lock-out of the burner, rearm the burner’s lock-out to restart,
by pushing the button on the control box. If, after a successful pump priming, the burner
locks-out after the prepurging, due to a fuel pressure drop in the pump, rearm the
burner’s lock-out to restart the burner.
Do never allow the pump working without oil for more than three
minutes.

COUNTRY
EXHAUST GAS LOSS
Exhaust gas loss by way of free heat will
occur as a result of the temperature
difference between the fuel-air mixture
entering the furnace chamber and the
gases discharged. Any increase in the
excess of air and the resultant higher
exhaust gas volume will cause the exhaust
gas loss to rise. The exhaust gas loss can
be calculated as follows:
qA= (tA- tL) A1+ B
CO2
qA= exhaust gas loss [%]
tA= exhaust gas temperature [°C]
tL= combustion air temperature [°C]
CO2= volumetric content of carbon
dioxide [%]
Example
Data measured in natural gas mode:
CO2content of exhaust gases: 10,8%
Exhaust gas temperature: 195°C
Air intake temperature: 22°C
The exhaust gas loss can be calculated
as follows:
qAf = (195-22)( 0,37 + 0,009) = 7,48%
10,8
Data measured in fuel oil mode:
CO2content of exhaust gases: 12,8%
Exhaust gas temperature: 195°C
Air intake temperature: 22°C
The exhaust gas loss can be calculated
as follows:
qAf = (195-22)( 0,49 + 0,007) = 7,83%
