FITTING THE BURNER TO THE BOILER AND
CONNECTING THE GAS PIPE
The burner is tted with a sliding attachment ange on the burner
head. When tting the burner to the boiler, this ange must be
correctly positioned is that the burner head penetrates the boiler by
the amount specied by the manufacturers of the boiler.
When the burner is tted correctly to the boiler, proceed whit the
connection of the gas feed pipe (see
BT 8780 and BT 1387).
The size of the gas feed pipe must be proportional to its length and
to the gas delivery rate in accordance with the UNI standard (see
diagram), and it must be perfectly airtight and properly tested before
running the initial tests on the burner.
It is essential to t a connector to this pipe, near to the burner, for the
easy dismounting of the burner and/or the opening of the boiler door.

The DUNGS mod. MB.... valve has a lter and gas pressure sta-
biliser, which means that only the cut-off cock and the vibration
damper joint should be tted to the gas feed pipe. A pressure
reduction unit should be installed outside the heating system only
in cases where the gas pressure exceeds the level permitted by
the standard (400 mm.C.A.).
It is recommended to put a bend directly on the burner gas train
before tting the detachable connector. This is to allow the opening
of the boiler door, when the connector itself has been opened.
These details are clearly illustrated in the following diagram.
HYDRAULIC CONNECTIONS (LIGHT OIL)
The connection pipes between tank and burner must be completely tight. We suggest to use copper or steel pipes of an adequate
diameter (see list and drawing).
At the rigid pipes ands it must be tted the fuel’s detection gates.
Filters, exible pipes and relative connection couplings are supplied
along with burner. Pump is equipped with suitable connecting points
(see drawing) for detection instruments (pressure gauge and vacuummeter). Pressure drop in suction must not exceed 4,6 mm.W.G.

ELECTRICAL CONNECTIONS
Electric lines should be at an adequate distance from
hot parts. Make sure that all electrical connections are
made with ex electric wire, with suitable size for the
voltage and absorbed power.
Maximum current absorbed = 600 VA
Minimum section of the feed line = 1mm2 with 230V.
For the LGB 22 control box, the intensity of the cell
current should be between 200 microamperes and 500
microamperes.
CHECKS PRIOR LIGHT OIL FIRING
Make sure that the nozzle with sprouting angle at 60° is suitable to
the boiler’s capacity.
In the list hereunder you nd the delivery values in kg/h of light oil
related to the nozzle’s size and to the pump’s pressure (normally
12 bar). (Please note that 1 light oil kg corresponds to 10.200
kcal about).
Make sure that the protrusion of the combustion head inside
the combustion chamber is according to boiler manufacturer’s
instructions.
Make sure that the return pipe in tank has no obstructions, such as
gates closed caps etc.
8502cmt18.tif
Probable obstructions could cause faults on the pump’s shaft or
ex pipe.
Open slightly the air purge device of the pump.
Disconnect the wire number 39 which feeds the pump motor from
the terminal on the contactor “K1” and connect it from moment the
terminal “K1.56” of the “input junction box” so as to feed directly
the pump motor.
Now close the reverser-switch on the burner and the general one
and make sure that the rotation sense is correct. Thus the pump
motor is connected and starts the pump witch sucks the light oil.
When the light oil ow the air purge device open the main switch
so as to stop the motor.
Be set original connections to the corresponding terminals.
The burner is thus ready to operate at light oil.

DUAL FUEL BURNER’S FIRING INDICATION
We suggest to start the burner with the liquid fuel, as in this case
the delivery is bound to the nozzle size whilst the gas delivery can
be easily changed by acting on the relative capacity adjuster.
If the burner is in the automatic version, the selector for the fuel
change connects a cyclic relay which inserts, tanks to an auxiliary
relay, components for the use of both fuels (valves, pressure
switches, pump etc.).
After having changed the position of the selector from gas to light oil
and voiceovers, it occurs to leave it stopped for at least 10 seconds
which is the time the cyclic relay needs to carry out its program.
ATTENTION
If the selector is moved from a position to another before the period
of 10 seconds, the cyclic relay stops in the middle of its program not
allowing to use the burner both with gas and with light oil.

1) Check that the pump and fan motors rotate in the right direction.
2) Make sure that the discharge of combustion products can take
G
place freely (chimney lock-gates should be open) and that there
L

S
H
is water in the boiler.
3) Open as much as considered necessary, the combustion air
regulator, and open by about half the air passage between
the disk and the head by operating the regulating screw of the
ame disk.
4) Close the main switch and the burner switch in order to connect
the burner and wait for it to start up. The burner is turned on in
this way, and will carry out the pre-ventilation phase. If the air
pressure exceeds the value at which the air pressure switch
has been set, the ignition transformer will be connected and
subsequently the light oil valve will be inserted. With the burner
operating, correct if necessary, the combustion air delivery.
5) The burner is tted with a device which optimises the combustion
by reducing or increasing the air passage between the disk and
the head. Maximum smoke intensity permissible is N° 2 of the
Bacharach scale with a Carbon Dioxide (CO2) value between
10 and 13 %. It is normally necessary to reduce the air passage
between the disk and the head when operating with a reduced
fuel delivery. This passage must be proportionately opened
more when the burner is working with a higher fuel delivery.
This manoeuvre can be carried out by operating the regulating
screw of the ame disk. After having modied the ame disk
position, it is then necessary to verify that ignition occurs
correctly.
4) Give current to the burner by connecting the main switch and
the burner switch. The burner is turned on in this way and will
then carry out the pre-ventilation phase. If the air pressure
exceeds the value at which the air pressure switch has
been set, the ignition transformer will be connected and,
subsequently, the gas valves will be inserted. The safety valve
opens completely while the principle valve, which incorporates
the regulation devices, opens twice. When it opens the rst time,
it realises the starting output immediately. The second time, it
opens gradually and when it is completely open the burner is
operating at the maximum value at which the maximum output
regulator has been set. At rst ignition, successive “shutdowns”
can occur, due to the following reasons:
a) The gas pipeline has not been adequately purged of air
and therefore the quantity of gas is not sufcient to allow
a stable ame.
b) A “shutdown” with flame presence can be caused by
ame instability, due to an incorrect air/gas ratio. This
can be remedied by varying the quantity of air and/or gas
delivered, in order to nd the correct ratio. It could also
be caused by an incorrect distribution of air/gas in the
combustion head. This can be corrected by operating the
regulation device of the combustion head – close more
(by loosening the regulating screw) or open more (by
tightening the regulating screw) the air passage between the
head and the gas diffuser. This can be done by operating
the regulating screw of the ame disk.
5) With the burner on, adapt delivery to the value which
corresponds with the potentiality desired (Methane gas = 8550
kcal/m3), by reading the meter. This output can be modied by
operating the special regulator incorporated in the valve, as
explained above.
STARTING UP AND REGULATION WITHMETHANE
GAS
N.B. Please refer to the last pages where specic instructions are
given with regard to regulating the gas delivery in function
with the type of valve tted on the burner.
In order to proceed with ignition, it is indispensable to carry out a
purge of the air contained in the pipeline and check, if the burner is
three-phase, that the sense of rotation of the motor is correct.
Then proceed as follows:
1) Make sure that the discharge of combustion products can take
place freely (chimney lock-gates should be open) and that there
is water in the boiler.
2) Open, as much as considered necessary, the combustion air
regulator, and open by about one third the air passage between
the head and the disk by operating the regulating screw of the
ame disk.
