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.

GAS 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.
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 ionization probe 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.
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 automatic furnace controller being
locked.
The trouble is indicated by the trouble
signal lamp lighting up.
The automatic furnace controller 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.

appropriate insulating material.
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. Check the ignition electrodes 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.
3. Check that the head is preset at 50%.

GAS VALVES AND INSTRUMENTS GROUP
The gas valves and instruments group used
with the furnace will be selected according to
the specific requirements to be met by a
burner system.
The following factors must be taken into
account:
• burner output
• furnace back pressure
• gas pressure loss of the burner head
• gas pressure losses of the gas valves and
instruments group
NOTE: Only gas trains assembled by the burner manufacturer and approved in
accordance with the burner test specifications.
EN676 compulsory kit and accessories in order to comply to the safety regulations.
Additional accessories and kits shall be installed by the installer in accordance to the
local safety regulations and codes of practise.
GAS CONNECTION PRESSURE
A minimum connection pressure must be
available upstream of the burner gas valve
to ensure the proper functioning of the
burner.

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.

PILOT GAS TRAIN CONNECTION
The pilot gas train is already installed to the burner and shall be connected to
the main gas supply line preferebly with flexible pipe.
The pilot gas train is composed of n° 2 safety valves and n°1 gas governor and
filter. Max inlet pressure 1 bar.
WARNING: Pilot gas train must be connected according to the drawing of the
gas line.
GAS VALVES ADJUSTMENT
Note : the pilot valves are pre-adjusted in the factory. To increase or reduce the
gas flow act on the gas governor.
GAS GOVERNOR ADJUSTMENT
The gas governor, with built-in filter, must be installed so as
to stabilise the outlet gas pressure and to avoid that
eventual impurities reach the gas valve. To increase gas
pressure, remove the cover of governor and turn screw C.
Unscrew screw C to reduce pressure, then fit the cover.
Note: the inlet gas pressure must not be higher than the
specified max. gas pressure.

START-UP: CHECKING PROCEDURE
CHECKS BEFORE COMMISSIONING:
• That the burner is assembled in
accordance with the instructions given
here.
• Setting the combustion components.
• All electrical connections must be correct.
• Check the burner motor for correct
direction of rotation.
• The heat generator must be ready for
operation, and the operating regulations
for the heat generator must be observed.
• The heat generator and heating system
must be filled with water and the
circulating pumps must be in operation.
• The temperature regulator, pressure
regulator, low water detectors and any
other safety or limiting devices that might
be fitted must be connected and
operational.
• The exhaust gas duct must be
unobstructed and the secondary air
system, if available, must be operational.
• An adequate supply of fresh air must be
guaranteed.
• Make a test of the all gas-carrying
elements for absence of leaks.
• With burner in starting position check that
air damper is in “CLOSED” position.
• Check that control box is unlocked and in
its original position.
• A standard-compliant measuring point
must be available, the exhaust gas duct up
to the measuring point must be free of
leaks to prevent anomalies in the
measurement results.
GAS START-UP
• Connect the measuring instruments for
the gas head pressure on the test
connection downstream of the gas damper
and the air pressure on the burner test
connection.
• Open the gas shut-off valve before the
gas-armatures and test the gas pressure
on the pressure gauge
• Set the “Manual-Automatic” selector
switch to “Manual”.
If the gas valves are tested for absence of
leaks, this should be continued until a
positive result is obtained. If a valve is
found to leak, the program will not step
forward to the control box.
The burner will start according to the
program flow of the control box.
Prior to the initial fuel feed start make
a functional test of the burner program
flow:
Gas system:
• Shortly open the gas shut-off valve
before the gas train until pressure is
available and close again.
• Start burner and check program flow for
correct start-up sequence:
1. Fan.
2. Pre-ventilation damper.
3. Check air pressure.
4. Partial-load damper.
5. Ignition.
6. Valves open.
7. Safety lock-out after expiry of
safety period (see control box) or shut-off
because of gas supply failure.
7. The burner will either stop as the gas
valves open (due to gas pressure
decrease) or lock out at the end of the
safety time.
• Unlock the control box.

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.
Secondary air will falsify the measured
results
Check that the exhaust gases have a
residual oxygen (O2) content as low as
possible and a carbon dioxide (CO2)
content as high as possible.
The carbon monoxide content of the
exhaust gases must be below the currently
applicable specifications in all load stages.
In the fuel oil combustion mode the
permissible soot number in the exhaust
gas is not allowed to be exceeded
DETERMINING THE VOLUMETRIC GAS
FLOW RATE
The thermal furnace output of a boiler (QF)
is the amount of heat supplied with the gas
in a unit of time.
When taking the burner into operation the
volumetric fuel flow rate should be
selected according to the nominal thermal
capacity of the boiler.
Example:
Nom. thermal output QN1000 kW
Boiler efficiency nK0,88
