Operation

Compact train

Operation
Safety function

Description of functions

When first powering up, after a power
cut or a lockout, after the gas supply has
been cut or after a shutdown for 24
hours, a gas valve sealing test is
performed before the burner is started,
with the fan motor in operation. A pre­ventilation time of 24 seconds begins
after the sealing test.

During the pre-ventilation time

- the air pressure is monitored

- a check is made for the presence of
any abnormal flame signals.

At the end of the pre-ventilation time

- the ignition is switched on

- the main and safety solenoid valves
are opened

- burner start-up

Monitoring

The flame is monitored by an ionisation
probe. The probe is fitted with insulation
to the gas head and is routed through
the turbulator into the flame zone. The
probe must not have any electrical
contact with earthed parts. The burner
switches to malfunction if a short circuit
occurs between the probe and the
burner earth. During burner operation,
an ionised zone is produced in the gas
flame through which a rectified current
flows from the probe to the burner tip.

The ionisation current must be at least
8 µA.

Safety functions

- If no flame is produced when the
burner is started (gas release), the
burner is switched off at the end of the
safety time which lasts no more than
3 seconds and the gas valve closes.

- If the flame is lost during operation,
the gas supply is cut within a second.
A new start-up sequence is activated.
If the burner starts, the operating cycle
starts running. Otherwise a lockout
occurs.

- If there is an air failure during pre­ventilation or operation, a lockout
occurs.

- If there is a gas failure, the burner
either stops or will not start. As soon
as sufficient gas pressure is available
again, the burner restarts.

During the regulator shutdown

- The control thermostat interrupts the
heating request

- The gas valves close

- The flame goes out

- The blower motor stops

- The burner is ready for operation

controls and monitors the forced draught
gas burner. The microprocessor­controlled program sequence ensures
the maximum consistency of the cycle
times involved, regardless of
fluctuations in the mains voltage or
ambient temperature. The control and
safety unit is designed to detect power
failures. Depending on the parameter
assignment, the unit either switches to
malfunction mode or goes into the
standby position if the power supply falls
below the mains voltage. In the standby
position, there is an automatic restart as
soon as the set threshold value is
exceeded by 105%.

Burner installation

Burner installation

Burner flange 3 is equipped with
elongated slots and can be used with a
hole Ø of 150 - 184 mm. These
dimensions comply with EN 226.
The insertion depth of the combustion
components can be adjusted to the
geometry of the combustion chamber by
sliding pipe bracket 2 on the burner's
flame tube. The installed depth remains
the same during fitting and removal.
The burner is secured to the connecting
flange, and therefore to the boiler, via
pipe bracket 2. This completely seals off
the combustion chamber.

Burner tube installation depth and
brickwork surround

Unless otherwise specified by the boiler
manufacturer, heat generators without a
cooled front wall require brickwork or
insulation 5 as shown in the illustration
opposite. The brickwork must not
protrude beyond the leading edge of the
flame tube, and should have a maximum
conical angle of 60°. Space 6 must be
filled with an elastic, non-flammable
insulation material.

Installation:

• Secure connecting flange 3 to the
boiler using screws 4

• Fit pipe bracket 2 to the burner pipe
and secure using screw 1. Tighten
screw 1 to a maximum torque of 6 Nm.

• Turn the burner slightly, guide it into
the flange and secure using screw 5.

Removal:

• Loosen screw 5

• Turn the burner out of the bayonet
socket and pull it out of the flange.

For assembly in the position with

the volute facing upwards, unclip
the display from its support, turn it
over 180° and refit it.

Exhaust gas evacuation system

To avoid unpleasant noise emissions,
right-angled connectors should not be
used on the flue gas side of the boiler.

On boilers with reverse firing, the
minimum flame tube insertion depth A
should be observed as per the boiler
manufacturer's instructions.

Inspection glass cooling

The burner body can be equipped with
an R1/8" connection to support a line for
cooling the boiler's inspection glass.

• To do this, drill through cast iron

projection 6 and cut a 1/8" thread.

• Use accessories article no. 12 056
459 for the threaded union and
connection hose.

General regulations applying to the
gas connection

• The gas train must only be connected
to the gas mains by a recognised
specialist.

• The cross-section of the gas line
should be of a size designed to
guarantee that the gas flow pressure
does not drop below the specified
level.

• A manual shut-off valve (not supplied)
must be fitted upstream of the gas
train.

• In Germany, a thermally triggered
shut-off valve (to be installed by the
customer side) must be fitted as

specified by the draft combustion

ordinance.
It is the responsibility of the fitter or his
representative to obtain approval for the
system at the same time as the burner is
commissioned. Only the fitter or his
representative can guarantee that the
system meets applicable standards and
regulations. The fitter should be in
possession of the corresponding official
permit, and should carry out the
corresponding sealing tests and purge
the system of air.

Electrical installation and connection
work must only be carried out by a
suitably qualified electrician. All
applicable regulations and directives
must be observed.

N.B. The applicable guidelines

Setting the ignition position

If a flame has been detected, the control and safety unit sets the burner to the ignition position as
soon as it receives the regulation authorisation.

- Set the fuel controller position and the air flap position according to the desired output level.
While doing so, constantly check the combustion values (CO, CO2 O2, soot, NOx). If required,
adapt the gas and fuel oil pressures at the valve and fuel-oil pump.

- Modify the position of the servomotors in the ignition position (lines with symbol). Proceed
as described on page 18, in the paragraph "Modifying the value of a servomotor position
setting".

- Warning: when modifying the value, the servomotor will move in real time. As a consequence,
the combustion values must be constantly checked.

The burner remains in ignition load.

Setting points P0-P9.

• Check the gas and fuel oil pressure. In the event of subsequent modifications, all setting values
must be corrected. For this reason, fine setting of the burner from point P9 must be carried out,

Menu 1: setting the servomotors
Setting with flame

It is only possible to adjust (limit) the low load and high load if, for each higher power point, all of
the channels also have setpoint values which are always higher. If this is not the case, the screen
opposite is displayed.
As it is not possible to limit the power range configured, the minimum and maximum operating

points (P0....P9) are automatically defined as the limit.

Example: 1
When the working field is set to always increase, it is possible to adjust the low load and high load.

Example: 2
When the working field is set to not always increase, it is not possible to adjust the low load and
high load.
The highlighted values in the box do not constantly increase.

Take care with dual fuel burners. The limits for low load and high load apply to both gas and fuel
oil operation. It is not possible to define the different limits for fuel oil and gas. If, for example, the
values are modified during gas mode, these values are also modified automatically for fuel oil
mode.

If values have already been defined, the values for the limits of low and high loads previously
specified for the other fuel are displayed in the menu point (left image).
If the values are modified, they must be confirmed for both fuels.
