4. SYSTEM COMPONENTS
4.1 Burner component
The burner component is in welded steel-plated housing. Under the burner housing
there’s an air valve section, it controls the air supply to the burner. A servomotor
drives the valves. The load controller or burner controller controls the servomotor.
The combustion air level is measured and monitored using air-pressure switches
(LD2). If you have a burner type TR the pressure switches are located on the upper
side of the burner. If you have a burner type RKB the switches are mounted under
the burner housing. The primary and secondary burner combustion devices are
situated in the cylindrical part of the burner. The flame monitoring device is mounted
on the side of the cylindrical part. The pilot burner is positioned at the centre of the
burner head. The pilot burner includes an electrical ignition. A high-voltage
transformer is included in the burner housing for electrical ignition. The gas supply
connection to a servomotor-driven gas quantity control valve is located under the
cylindrical part of the burners.
4.2 Air fan component
The air fan is positioned under the burner. The air fan supplies the required
combustion air. This air fan has a directly coupled and balanced fan wheel. The fan
wheel is driven by an electromotor. The air fan of a TR burner is directly connected
to the air-valve section. The air van of an RKB burner is separate and stands on the
floor.
The connection is made using a flexible sleeve. Vibration isolators are used when
mounting the air fan on the floor. An electrical circuit in the burner control panel and
the frequency controller provide the variable speed of the electromotor. The air fan
can, therefore, provide the required air quantity based on the measured air quantity.
The standard air fan includes an inlet grid to prevent coming into contact with
moving parts. A plate silencer is provided on the air fan inlet for noise reduction
purposes. Cylindrical noise silencers are available as an option.
4.3 Gas train
The gas train controls the gas supply from the distribution network. Several monitor
and control units are mounted on the gas train to control the burner gas supply.
The maximum supply pressure for the system is indicated on the burner
nameplate.
Shut-off valve (pos. A1)
De shut-off valve (A1) shuts off the gas supply to the burner system in case of:
•Fire or other emergencies.
•Maintenance work on the gas train equipment.
•Leakage of or between parts after the valve.
•Shutting down the burner system for a long period of time.

Page. 6
LMV2635.EN.202001_V2
Filter (pos. F1)
The filter (F1) prevents dirt and welding globules from the gas supply line from
getting into the equipment of the gas train. This protects the equipment from
damage caused by contamination.
Safety valves (pos. VA1 and VA2)
These safety valves automatically open/close the gas supply to the burner. Two gas
safety valves (VA1 + VA2) are used for safety reasons.
The second safety valve (VA2) has an integrated gas pressure regulator that makes
sure the gas pressure on the burner head is constant.
Minimum gas pressure safety device (pos. LD1)
The pressure switch (LD1) is activated when the main gas pressure reach under the
minimum limit value. The setting value is determined during the commissioning of
the burner.
Maximum gas pressure safety device (pos. HD)
The HD pressure switch monitors the maximum burner/boiler capacity and is
mounted on the burner head to control the burner load by means of air pressure.
The settings of the pressure switches is determined when commissioning the burner
system.
Manometer (pos. M) en press-button valve (pos. K2)
By pushing on the press-button valve the supplied inlet pressure can be read off the
manometer.
Manometer (pos. M) and push button valve (pos. K2)
Press the push button valve to read the supplied inlet pressure on the manometer.
4.4 Pilot gas line
Shut-off valve (pos. K1)
The ball valve (K1) is used to bleed the gas supply line. The bleed line has to
include a separate pipe through the roof to the outside air. The opening has to be
protected against contamination, dirt and rain.
Plug off the ball valve if there is no bleeding line.
Pilot gas solenoid valves (pos. MK1/MK2)
The pilot gas solenoid valves automatically open or close the gas supply to the pilot
burner (pos. AB).

4.5 Control panel
The control panel includes all electrically controlled operation, monitoring and
control units of the burner, air fan, gas train, boiler and other secondary connected
devices. The electric circuits of all devices and units are connected to the control
panel in such a way that the total system can operate safely.
These circuits can be classified into the following main groups:
•Boiler/safety circuit.
•Thermostat (start) circuit.
•Burner control.
•Load control.
•External control (Fiduface).
•Failure indicator lights.
•Motor groups/fuses.
•Control switches and reset buttons.
•Optional CO2-circuit and CO-detector circuit.
4.6 Control switches and reset buttons on the control panel
The control panel includes a few switches and press button valves:
•Fire on/off switch.
•Selector switch for load control with the following two options:
1 = Automatic, modulated by load controller.
2 = External, the burner load and on/off status is controlled by the climate or
process computer.
•Reset, resets all failures.
The following control panel switches are optional:
•Selector switch gas/oil.
•Selector switch heat/steam.
•CO2dosing on/off.
•Flue gas valve open/closed.
4.7 Frequency control
A circuit in the control panel controls the air fan electromotor. A frequency control
unit, not included on the control panel, controls the air fan rotational speed based on
the burner load. The speed is controlled directly from the burner control unit by
sending a 0-10 V/4-20 mA signal to the frequency control unit.
Common settings:
Frequency for low flame approx. 25 Hz (= ± 1400 cycles).
Frequency for high flame approx. 50 Hz (= ± 2800 cycles).

5. START SEQUENCE
When the gas pressure is nominal, the correct power is supplied to the control
panel, the safety valves are closed, the on/off thermostat emits an “on” signal and
all other boiler values are within the limits, the burner will start when the burner
on/off switch is set to 1.
The start-up sequence is as follows:
A. After switching the system on, the air fan starts at low speed, sometimes after a
short delay.
B. Once the air fan is at nominal speed, the servomotor of the air quantity control
valve (pos. HR2) opens fully. When the servomotor that controls the air quantity
control valve doesn’t make the complete pre-set stroke, the air quantity control
valve will not be sufficiently opened. The burner will be shut off and the system
goes into lockout. An error message is displayed. The air fan will be set to
maximum speed (50 Hz) approximately linear to the air valves to ventilate the
system.
C. If the air quantity control valve is opened the pre-purge cycle starts. During the
30 seconds pre-purge cycle the boiler furnace is ventilated, to clear any
remaining flue gas. During the pre-purge cycle the position of the air quantity
control valve and of the air pressure are checked continuously.
D. At the end of the pre-purge cycle the air fan is set to low speed (+/- 25 Hz) and
the air quantity control valve is positioned to the start/low flame position.
The gas quantity control valve (pos. HR1) controlled by a servomotor is also
positioned to the start/low flame position. The minimum air pressure is checked
during operation by a second air pressure switch (pos. LD2 low).
F. All the air and gas controls are in now in the start position. The next step is to
light the pilot flame. A few seconds after reaching the start position the ignition
transformer is switched on. It make an electrical spark between the ignition
electrodes.
G. After three (3) seconds the pilot gas valve (pos. MK) opens and the spark lights
the gas. After another five (5) seconds the flame monitoring device checks
whether the UV scanner detects a pilot flame. The 5 seconds period during
which the pilot flame is lighted is called the first safety time. At the end of the
first safety time the pilot flame should be burning stable and the electrical spark
is switched off. The flame monitoring unit checks the flame continuously during
operation.
If the flame is not formed in the first safety time the flame monitoring unit goes
into lockout and an error message is displayed on the electronic module.
G. If the flame monitoring unit detects the pilot flame, the system continues the
ignition procedure after a short time period. The main safety valves (pos. VA1
and VA2) open to ignite the main flame. The pneumatic gas pressure regulator,

Page. 9
LMV2635.EN.202001_V2
which is mounted on the second safety valve (pos. VA2), makes sure the
correct output gas pressure for the burner load is obtained.
Five (5) seconds after opening the safety valves the pilot gas is shut off.
The main flame has to be stable, itis checked by the flame monitoring unit
continuously.
The 5 seconds during which the pilot valve (pos. MK) and the main valves (pos.
VA1 and VA2) are in the open position is called the second safety time. If the
flame is not formed within this time the flame guard goes into lockout and an
error message is displayed on the electronic module.
The maximum gas pressure switch (pos. HD1) ensures an easy steady start of
the main flame. It is only active when starting the flame. The minimum gas
pressure switch (pos. LD1) monitors the supply gas pressure continuously at
the lowest applicable level.
H. After the main flame has formed and the start sequence of the burner control
panel is successfully gone through, the burner is “in operation” on low flame.
Approx. 35 seconds after opening the main valves the load controller starts
setting the load.
I. If the load control switch on the control panel is set to 1 Auto, the burner load
and switching on and off will be controlled by the load control unit.
The maximum gas pressure switch (pos. HD) monitors the maximum burner
load by measuring the gas pressure.
