Burner description
MULTIFLAM 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 problems 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 EN676 -
EN267 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
STARTUP MODE
As soon as the furnace system is required
to supply heat, the burner control circuit
will close and the program flow started.
When the program has come to its end,
the burner will be turned on.
An automatic test is made for the tightness
of the gas valves prior to each burner start.
The air damper is in its closed position
when the burner is out of operation.
The electric actuator will open the closed
air damper to its full-load position so that
the burner will ventilate the furnace and
the exhaust hoods with the specified air
rate.
Shortly after the preventilation 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 in a linked control concept with the
gas damper. 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 control box 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.
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 (shut-off on trouble).
A shut-off on trouble 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 shut-off on trouble
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 shut-off on trouble 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.

The ignition transformer will be started.
At the end of the pre-ignition time the
ignition gas solenoid valves will be opened
to allow gas to flow into the pilot burner.
The ignition electrodes incorporated in the
pilot burner will ignite the ignition gas.
The UV cell gives flame signal to
control box so that the safety shut-off
valves will be opened.
The gas will be fed to the gas nozzles via
the gas damper while combustion air is
supplied by the fan.
Gas and air will be intensively mixed in the
mixing unit and ignited by the pilot flame
with a specified safety period (minimum
furnace heat generating rate).
After the safety period has run down the
pilot burner will be turned off.
Attention:
If there are shut-off dampers in the flue
gas tract they must be completely open.
Otherwise there will be a high danger of
low-speed detonation or explosion!
GAS 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 compound control system will be fed
with the OPEN or CLOSE command via
the regulator and thus increase or
decrease the gas and air flow rates.
This compound control system will vary
the positions of the gas control valve and
air damper and thus regulate the gas flow
rate in a linked concept with the air flow
rate. The burner can either be controlled
by a 2-stage sliding or, if a respective
controller is provided, a stepless control
concept.
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 always be turned off out of
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 thus be
greatly minimized.

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.

INSTALLATION
Heavy oil preparation ring
All installations using heavy oil burners have
to be completed with a forced oil preparation
ring in order to guarantee oil supply to the
burner at suitable temperature and pressure
(temperature +/- 50° C, pressure 3 bar).
For heavy oil with more than 50°E at 50°C
Ecoflam recommends to lower the maximum
output of 10-20% and work in excess of air in
order to grant better operation and reduce
maintenance.
Installation with heavy oil must provide to
the burners:
- CONSTANT PRESSURE
- CONSTANT TEMPERATURE
To size correctly the ring for the heavy oil supply
consider the diagram of the pre-heating
temperature of the heavy oil according to
viscosity and the pump pressure according to
temperature.
Ecoflam heavy oil and dual fuel heavy oil
burners do have in the electrical panel the fuel
temperature device GEFRAN that adjusts the
temperature of the heavy oil and grants
temperature stability.

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. 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
Feeding line for heavy oil
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.

Gas line
GAS CONNECTION PRESSURE
A minimum connection pressure must be
available upstream of the burner gas valve
to ensure the proper functioning of the
burner.
WARNING: the total gas pressure loss
must always be smaller than the available
gas flow pressure.
For the installation of the valves and
instruments group take care to observe the
mounting instructions supplied by their
manufacturers (these are packed with the
equipment).
The gas line installed to the burner must
be dimensioned in accordance with the
throughput rate and the available
pressure.
For selecting the nominal bore “DN” of the
gas valves and instruments group care
should be taken to observe the flue
resistance of the boiler and the gas
pressure loss of the burner and valves and
instruments group.
GAS VALVES AND INSTRUMENTS
GROUP
The gas valves and instruments group can
be connected directly to the gas feed line.
Take care to observe the correct order of
installation and direction of flow (arrow on
housing).
Check the valves and instruments and
connection pieces for absence of dirt
particles and foreign matter before
installation and initial operation. To provide
effective conditions for start-up make sure
the distance between the burner and the
gas stop valve is as short as possible.
LEAK TEST
The gas line upstream of the burner gas
valves and instruments group must be
installed in accordance with the applicable
regulations, checked for absence of leaks,
vented and certified accordingly by the gas
installation company. The screwed unions
and flanged joints must be checked for
proper tightness (by making a pressure
test). The leak test must be made under
pressure using approved foaming agents
which do not cause corrosion. For steam
boiler furnaces the result of the leak test
must be duly certified.
VENTING
Prior to taking the burner into operation or
after any repair work make sure to vent the
complete gas feed line and the gas valves
and instruments group into the open
atmosphere (e.g. by means of a hose)
taking care to avoid any hazards.
In no case should the gas line be vented
into the heating or furnace chambers.
Make use of a test burner to check the
gas-carrying spaces are free from an
inflammable gas mixture.
SUPPORT
The valves and instruments group must be
supported with a telescopic jacking
member or similar during and after
installation (e.g. on filter and valve).
JOINT
It is recommended to provide an easy to
disconnect joint (with planar sealing faces)
to facilitate repair work on the boiler
(furnace) and allow the boiler door to be
swivelled out if required.
