Function  General safety functions
Description of functions
When the system is switched on for the
first time, after a power failure or safety
shutdown, after a lack of gas or after the
system has been out of operation for 24
hours, the pre-ventilation period begins.
During prepurge period:
- blower pressure is monitored
- the combustion chamber is monitored for
flame signals.
At the end of the prepurge period:
- ignition is switched on.
- main and safety valve are opened.
- burner starts.
Monitoring
The flame is monitored by an UV Cell.
The burner switches to lock-out if it
doesn't survey the light of the flame.
Safety functions
- If no flame is produced when the burner
is started (gas release), the burner will be
switched off at the end of the safety
period, lasting no more than 3 seconds,
and the gas valve will close.
- If the flame goes out during operation,
the gas supply is interrupted within one
second. A restart takes place. Once the
burner starts, operation is continued.
Otherwise, a safety lock-out occours.
- If there is a lack of air during reventilation
or operation, a safety lock-out occours.
- If there is a lack of gas, the burner does
not begin operation or switches off.
In the event of controller shutdown
- Controller thermostat interrupts heat
request.
- Gas solenoid valves close.
- Flame goes out.
- Burner motor switches off.
- Burner is ready for operation.
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 (gas) 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.
Gas Leakage control for burners in
PRE version
The relevant function is ACTIVE as a
standard. Before commissioning the
burner, please check is this feature is
“ACTIVATED” (look inside menu on
section 5 “Operating Control and
Displays”page 64, fig.5-32”).
If it is “NOT ACTIVATED” and it is not
mandatory to fit the valve proving, a
suitable gas train must be fit. Such a gas
train must be equipped with a pressure
switch upstream of the first gas valve
(referring to the picture on page 8, the F4
min. gas pressure switch must be fit
before the device Y12)
It works as follows:
The valve leakage test checks whether
the main gas valves are leak-tight. The
supply gas pressure is used for this
purpose. Since the valve leakage test line
(space between the two main valves)
burns empty in the event of a shut-off, this
part is normally without pressure when
starting (gas pressure > min. = 0). The
FA1 checks this. Main gas 1 is then
opened shortly and gas flows into the test
line (gas pressure > min. changes from 0
to 1). This pressure must then subsist for
30 seconds. The valve leakage test is
then deemed to be completed.If the valve
leakage test line is not empty at the start
(e.g. as a result of a previous fault shut-
down), main gas valve 2 opens first. The
valve leakage test line is vented (into the
combustion chamber or over the roof,
depending on the system; for suggested
circuit, see Appendix). It is checked,
whether the line remains pressureless for
30 seconds. Otherwise the procedure is,
as described previously.

The heavy oil burner pump used is a self-
priming gear pump, which must be
connected as two-line pump via a bleed
filter. There is an intake filter and an oil
pressure regulator integrated in the pump.
Pressure gauges for pressure
measurements and negative pressure
measurements must be connected before
the equipment is commissioned.
NB: before starting the burner, check that
the return pipe is open. An eventual
obstraction could damage the pump
sealing device.

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. All oil ring installations must comply with the local safety rules existing in the country of installation
