3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1 WORKING POSITION
The burner is designed for operation in positions 1and 2only. Installation 1is the preferred option as it is the
only one that enables maintenance to be performed as described later on in this manual.
Operation is possible with installation option 2though maintenance cannot be performed with the burner con-
nected to the boiler. Note that any other installation position is likely to hinder the unit’s proper operation. Instal-
lations 3, 4 and 5are prohibited as safety is compromised.
3.2 BOILER FIXING
Important: with some boilers it is possible that the CO values exceed those declared in this manual.
To reduce these emissions, the recirculation pipe supplied must be used.
To fit the burner to the boiler it is necessary to carry out the following:
³If necessary insert the recirculating pipe (1) on the burner blast tube (2) and fix it with the screw (3), (see
fig. 2).
Attention: respect the dimensions, as described in chapter “2.2 OVERALL DIMENSIONS“ at page 3.
³Put on the flange (4) the screw and two nuts, (see fig. 4).
³Widen, if necessary, the insulating gasket holes (5, fig. 5).
³Fix the flange (4) to the boiler door (6) using screws (7) and (if necessary) the nuts (8) interposing the
insulating gasket (5), (see fig. 3).

3.3 HYDRAULIC SYSTEMS
*ONLY FOR ITALY: Automatic shut-off device as per Ministry of Internal Affairs’ regulation no. 73 dated 7/29/71.
H= difference of level; L= max. length of the suction line; I. D. = internal diameter.
PRIMING PUMP:
On the system in fig. 6 it is sufficient to loosen the suction gauge connec-
tion (6, fig. 7) and wait until oil flows out.
On the systems in fig. 8 and 9 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least 20 sec-
onds before repeating the operation.
The pump suction should not exceed a maximum of 0.4 bar (30 cm Hg).
Beyond this limit gas is released from the oil. Oil pipes must be completely
tight.
In the vacuum systems (fig. 9) the return line should terminate within the oil
tank at the same level as the suction line. In this case a non-return valve is
not required. Should however the return line arrive over the fuel level, a
non-return valve is required. This solution however is less safe than previ-
ous one, due to the possibility of leakage of the valve.

³
The burner is designed to accommodate the installation of
light oil supply pipes on either side.
³
It is necessary to install a filter on the fuel supply line.
³
The pump is designed to allow working with two pipes. In
order to obtain one pipe working it is necessary to unscrew
the return plug (2), remove the by-pass screw (3) and then
screw again the plug (2). (See fig. 7).
³
Before starting the burner make sure that the return pipe-
line is not clogged. An excessive back pressure would
cause the damage of the pump seal.

5. MAINTENANCE
Disconnect the electric supply to the burner by switching off the main power switch and close the
light oil shut-off valve before maintaining or checking the system.
The burner requires scheduled maintenance that must be carried out by qualified personnel and in compli-
ance with local legislation.
Scheduled maintenance is vital for the smooth operation of the burner; it avoids waste of fuel and reduces
harmful emissions into the atmosphere.
THE FUNDAMENTAL OPERATIONS TO CARRY OUT ARE AS FOLLOWS:
³Check there are no occlusions or obstructions in the inlet or return pipes, in the air suction areas and in
the combustion product waste pipe.
³Check that the positioning of the combustion head is correct and that it is properly fixed to the boiler.
³Clean the combustion head at the fuel outlet.
³Clean the fuel suction line filter and the pump filter.
³Check that the burner electrical connections are correct.
³Clean the flame detector.
³Check for correct fuel consumption.
³Check the combustion head (fig. 13, page 8) and the air damper are set correctly (fig. 13, page 8).
³Replace the nozzle if necessary (fig. 11, page 8) and check the correct position of electrodes (fig. 14,
page 9).
³Clean the fan.
Leave the burner working without interruptions for 10 min. and check the right settings at 1st and 2nd stage
of all components stated in this manual. Then carry out the analysis of the combustion by checking:
- Smoke index as per the Bacharach scale; - CO2percentage (%); - CO content (ppm);
- NOx content (ppm); - Smoke temperature at the chimney

6. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for problems that could cause a failure to
start or a bad working of the burner.
A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box
(5, fig. 1, page 2).
When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if the
burner functions correctly, the lock-out can be attributed to a temporary fault.
If however the lock out continues the cause must be determined and the solution found.
WARNING
6.1 The manufacturer cannot accept responsibility for any damage to persons, animals or property due to
error in installation or in the burner adjustment, or due to improper or unreasonable use or non observance
of the technical instruction enclosed with the burner, or due to the intervention of unqualified personnel.
FAULTS POSSIBLE CAUSES SOLUTION
The burner doesn’t
start when the limit
thermostat closes.
Lack of electrical supply.
Check presence of voltage in the
L1 - N clamps of the 7 pin plug.
Check the conditions of the fuses.
Check that safety thermostat is not
lock out.
Heating and start thermostats are
faulty. Replace them.
The connections in the control box
are wrongly inserted.
Check and connect completely all the
plugs.
Lock-out because of a failure to turn
off (event B page 10).Call technical assistance.
The burner remains
in the pre-purge
phase.
The flame detector sees strange light
(Led 1 is switched on). Eliminate the light.
Burner runs normal-
ly in the prepurge
and ignition cycle
and locks out after 5
seconds ca.
The flame detector is dirty. Clear it.

3. INSTALLATION
DIE INSTALLATION DES BRENNERS MUSS IN ÜBEREINSTIMMUNG MIT DEN ÖRTLICHEN GESETZEN
UND VORSCHRIFTEN AUSGEFÜHRT WERDEN.
3.1 BETRIEBSPOSITION
Der Brenner ist ausschließlich für den Betrieb in den Positionen 1und 2vorbereitet.
Die Position 1ist vorzuziehen, da sie die einzige ist, die eine Durchführung der Wartung wie hier folgend in die-
ser Anleitung beschrieben ermöglicht. Die Position 2ermöglicht den Betrieb, aber nicht die Wartung mit dem
Einhängen am Heizkessel. Jede andere Position kann den korrekten Betrieb des Geräts beeinträchtigen.
Die Positionen 3, 4und 5sind aus Sicherheitsgründen verboten.
3.2 BRENNERMONTAGE
Achtung: Bei manchen Heizkesseln können die CO-Werte die in diesem Handbuch angegebenen über-
schreiten. Um diese Emissionen zu verringern muss das mit der Ausstattung gelieferte Rezirkulations-
rohr benutzt werden.
Zur Installation des Brenners am Heizkessel sind folgende Vorgänge auszuführen:
³Falls notwendig das Rezirkulationsrohr (1) an dem Brennerrohr (2) montieren und mit der Schraube (3)
befestigen, (siehe Abb. 2). Achtung: die im Kapitel “2.2 ABMESSUNGEN“ auf Seite 3 beschriebene Ab-
messungen befolgen.
³Die Schraube und die beiden Muttern am Flansch (4) montieren, (siehe Abb. 4).
³Falls erforderlich, die Bohrungen der Isolierdichtung (5, Abb. 5) erweitern.
³Mit den Schrauben (7) und (falls erforderlich) den Muttern (8) den Flansch (4) an der Kesseltür (6) mit
Isolerdichtung (5) montieren, (siehe Abb. 3).

3.3 ÖLVERSORGUNGSANLAGE
*NUR FÜR ITALIEN: automatische Absperrung gemäß Rundschreiben des Innenministeriums Nr. 73 vom 29.7.71.
H = Höhenunterschied; L = max. Länge der Saugleitung; øi = Innendurchmesser der Leitung.
AUFFÜLLEN DER PUMPE MIT HEIZÖL:
Bei der in Abb. 6 dargestellten Anlage ist es ausreichend, wenn man den
Vakuummeteranschluß (6, Abb. 7) lockert und das Austreten des Brennstoffes
abwartet.
Bei den in Abb. 8 und in Abb. 9 dargestellten Anlagen den Brenner starten und das
Auffüllen abwarten. Sollte vor Eintritt des Brennstoffes eine Störabschaltung erfolgen,
mindestens 20 Sekunden warten und danach den Vorgang wiederholen.
Der max. Unterdruck in der Saugleitung von 0,4 bar (30 cm Hg) darf nicht unter-
schritten werden. Unter diesem Wert bilden sich im Brennstoff Gase. Sich
unbedingt vergewissern, daß die Leitungen absolut dicht sind.
Bei den Anlagen nach Abb. 9, empfehlen wir, die Ölrücklauf-Leitung in gleicher
Höhe wie die Saugleitung im Tank enden zu lassen. Es kann auf ein Fußventil in
der Saugleitung verzichtet werden. Endet die Rücklauf-Leitung über dem Ölniveau
wird auf der Saugseite zwingend ein Fußventil benötigt, wobei dieses dann bei
Verschmutzung Probleme verursachen kann.

³
Der Brenner ist für den Einbau der Heizölversorgungsrohre
auf beiden Seiten vorgerüstet.
³
In der Brennstoff–Ansaugleitung muß ein Filter eingebaut
werden.
³
Die Pumpe ist werksseitig für den Zweirohr-Betrieb einge-
richtet. Wird ein Pumpen-Einrohrbetrieb für notwendig
erachtet, so ist der Rücklauf-Schlauchleitungsstopfen (2) zu
lösen und die By-Pass Schraube (3) zu entfernen. Danach
ist der Rücklauf-Schlauchleitungsstopfen wieder einzu-
schrauben. (Siehe Abb. 7).
³
Es muß sichergestellt werden, daß die Ölrücklauf-Leitung
ohne Verengung und Verstopfung frei in den Tank zurückge-
führt wird. Durch Druckerhöhung von mehr als 0,5 bar im
Rücklauf wird die Ölpumpe undicht.
