FIRING RATE (A)
The RL 190 Model burners can work in two
ways: one-stage and two-stage.
1st stage DELIVERY must be selected within
area A of the adjacent diagram.
2nd stage DELIVERY must be selected within
area B. This area provides the maximum deliv-
ery of the burner in relation to the pressure in
the combustion chamber.
Important:
The FIRING RATE area values have been
obtained considering a surrounding temperature
of 20°C, and an atmospheric pressure of 1000
mbar (approx. 100 m above sea level) and with
the combustion head adjusted as shown on
page 5.
TEST BOILER (B)
The firing rates were set in relation to special
test boilers in accordance with the methods
defined in EN 267 standards.
Figure (B) indicates the diameter and length of
the test combustion chamber.
Example: delivery 65 kg/hour:
diameter = 60 cm; length = 2 m.
Whenever the burner is operated in a much
smaller commercially-available combustion
chamber, a preliminary test should be per-
formed.
INSTALLATION
BOILER PLATE (C)
Drill the combustion chamber locking plate as
shown in (C). The position of the threaded holes
can be marked using the thermal screen sup-
plied with the burner.
BLAST TUBE LENGTH (D)
The length of the blast tube must be selected
according to the indications provided by the
manufacturer of the boiler, and in any case it
must be greater than the thickness of the boiler
door complete with its fettling. The length avail-
able, L (mm), is 370 mm.
For boilers with front flue passes 12) or flame
inversion chambers, protective fettling in refrac-
tory material 10) must be inserted between the
boiler fettling 11) and the blast tube 9).
This protective fettling must not compromise the
extraction of the blast tube.
For boilers having a water-cooled front the
refractory fettling 10)-11)(D) is not required
unless it is expressly requested by the boiler
manufacturer.
SECURING THE BURNER TO THE BOILER (D)
Disassemble the blast tube 9) from the burner 6)
by proceeding as follows:
- Loosen the four screws 3) and remove the
cover 1).
- Remove the screws 2) from the two slide bars
5).
- Remove the two screws 4) fixing the burner 6)
to the flange 7).
- Withdraw the blast tube 9) complete with
flange 7) and slide bars 5).
Secure flange 7)(D) to the boiler plate interpos-
ing the supplied gasket 8)(D). Use the 4 screws
provided after having protected the thread with
antiscruffing products.
The burner-boiler seal must be airtight.

CHOICE OF NOZZLES FOR 1ST AND 2ND
STAGE
Both nozzles must be chosen from among those
listed in Table (A).
The first nozzle determines the delivery of the
burner in the 1st stage.
The second nozzle works together with the 1st
nozzle to determine the delivery of the burner in
the 2nd stage.
The deliveries of the 1st and 2nd stages must
be contained within the value range indicated on
page 6.
Use nozzles with a 60° spray angle at the rec-
ommended pressure of 12 bar.
As a rule the two nozzles have equal deliveries
but the 1st stage nozzle may have a delivery
less than 50% of the total delivery when a
reduction of the counter-pressure peak is
desired at the moment of starting (the burner
allows good combustion rates also with a 40 -
100 % ratio between the 1st and 2nd stage).
Example
Boiler output = 1630 kW - efficiency 90 %
Output required by the burner =
1630 : 0,9 =1812 kW;
1812 : 2 =906 KW per nozzle;
therefore, two equal, 60°, 12 bar nozzles are
required:
1° = 18 GPH - 2° = 18 GPH,
or the following two different nozzles:
1° = 16 GPH - 2° = 20 GPH.
NOZZLE ASSEMBLY
At this stage of installation the burner is still dis-
assembled from the blast tube; it is therefore
possible to fit the nozzle with the box spanner
1)(B) (16 mm), after having removed the plastic
plugs 2)(B), fitting the spanner through the cen-
tral hole in the flame stability disk. Do not use
any sealing products such as gaskets, sealing
compound, or tape. Be careful to avoid damag-
ing the nozzle sealing seat. The nozzles must
be screwed into place tightly but not to the max-
imum torque value provided by the wrench.
The nozzle for the 1st stage of operation is the
one lying beneath the firing electrodes Fig. (C).
Make sure that the electrodes are positioned as
shown in Figure (C).
Finally remount the burner 3)(D) on the slide
bars 2) and slide it up to the flange 5), keeping it
slightly raised to prevent the flame stability disk
from pressing against the blast tube.
Tighten the screws 1) on the slide bars 2) and
screws 4) fixing the burner to the flange.
If it proves necessary to change a nozzle with
the burner already fitted to the boiler, proceed
as outlined below:
- Pull back the burner on its slide bars as shown
in fig. (D)p.10.
- Remove the nuts 1)(E) and the disk 2)
- Use spanner 3)(E) to change the nozzles.
COMBUSTION HEAD SETTING
The setting of the combustion head depends
exclusively on the burner delivery in the 2nd
stage - in other words, the combined delivery of
the two nozzles selected in table (A).
Turn screw 4)(F) until the notch shown in dia-
gram (G) is level with the front surface of flange
5)(F).
Example:
The RL 190 Model with two 18 GPH nozzles
and 12 bar pump pressure.
Find the delivery of the two 18 GPH nozzles in
Table (A):
76,4 + 76,4 = 152,8 kg/h.
Diagram (G) indicates that for a delivery of
152,8 kg/h the RL 190 Model requires the com-
bustion head to be set to approx. four notches,
as shown in Figure (F).

IHYDRAULIC SYSTEM
FUEL SUPPLY
Double-pipe circuit (A)
The burner is equipped with a self-priming pump
which is capable of feeding itself within the limits
listed in the table at the side.
The tank higher than the burner A
Distance "P" must not exceed 10 meters in
order to avoid subjecting the pump's seal to
excessive strain; distance "V" must not exceed
4 meters in order to permit pump self-priming
even when the tank is almost completely empty.
The tank lower than the burner B
Pump depression values higher than 0.45 bar
(35 cm Hg) must not be exceeded because at
higher levels gas is released from the fuel, the
pump starts making noise and its working life-
span decreases.
It is good practice to ensure that the return and
suction lines enter the burner from the same
height; in this way it will be less probable that
the suction line fails to prime or stops priming.
The loop circuit
A loop circuit consists of a loop of piping depart-
ing from and returning to the tank with an auxil-
iary pump that circulates the fuel under
pressure. A branch connection from the loop
goes to feed the burner. This circuit is extremely
useful whenever the burner pump does not suc-
ceed in self-priming because the tank distance
and/or height difference are higher than the val-
ues listed in the Table.

•HYDRAULIC CONNECTIONS (B)
The pumps are equipped with a by-pass that
connects return line with suction line. The
pumps are installed on the burner with the by-
pass closed by screw 6)(B)p.11.
It is therefore necessary to connect both hoses
to the pump.
The pump will break down immediately if it is run
with the return line closed and the by-pass
screw inserted.
Remove the plugs from the suction and return
connections of the pump.
Insert the hose connections with the supplied
seals into the connections and screw them
down.
Take care that the hoses are not stretched or
twisted during installation.
Install the hoses where they cannot be stepped
on or come into contact with hot surfaces of the
boiler.
Now connect the other end of the hoses to the
suction and return lines by using the supplied
nipples.

Use flexible cables according to regulation EN
60 335-1:
• if in PVC boot, use at least HO5 VV-F
• if in rubber boot, use at least H05 RR-F.
All the cables to be connected to the burner ter-
minal strip 8)(B) must be routed through the fair-
leads.
The fairleads can be used in various ways. One
example is given below:

TS - Safety control device system:
This operates when TL is faulty.
Important: the burner is factory set for two-

Alternatively, if single stage operation is
required, instead of control device TR install a
jumper lead between terminal 11 and 12 of the
terminal strip.
The RL 190 burner has been type- approved for
intermittent operation. This means they should
compulsorily be stopped at least once every 24
hours to enable the control box to perform
checks of its own efficiency at start-up. Burner
halts are normally provided for automatically by
the boiler load control system.
If this is not the case, a time switch should be fit-
ted in series to IN to provide for burner shut-
down at least once every 24 hours.
WARNING: Do not invert the neutral with
the phase wire in the electricity supply line.

PUMP PRIMING
- Before starting the burner, make sure that
the tank return line is not clogged.
Obstructions in the line could cause the
sealing organ located on the pump shaft to
break. (The pump leaves the factory with the
by-pass closed).
- In order for self-priming to take place, the
screw 3)(A) of the pump must be loosened to
bleed off the air contained in the suction line.
- Start the burner by closing the control devices
with switch 1)(B) in the "ON" position. The
pump must rotate in the direction of the arrow
marked on the cover.
- The pump can be considered primed when the
light oil starts coming out of the screw 3). Stop
the burner: switch 1)(C) set to "OFF" and
tighten the screw 3).
The time required for this operation depends
upon the diameter and length of the suction tub-
ing. If the pump fails to prime at the first starting
of the burner and the burner locks out, wait
approx. 15 seconds, reset the burner, and then
repeat the starting operation as often as
required. After 5 or 6 starting operations allow 2
or 3 minutes for the transformer to cool.
Do not illuminate the photocell or the burner will
lock out; the burner should lock out anyway
about 10 seconds after it starts.
Important: the a.m. operation is possible
because the pump is already full of fuel when it
leaves the factory. If the pump has been
drained, fill it with fuel through the opening on
the vacuum meter prior to starting; otherwise,
the pump will seize. Whenever the length of the
suction piping exceeds 20-30 meters, the supply
line must be filled using a separate pump.

BURNER CALIBRATION
FIRING
Set switch 1)(B) to "ON".
During the first firing, during the passage from
the 1st to the 2nd stage, there is a momentary
lowering of the fuel pressure caused by the fill-
ing of the 2nd stage nozzle tubing. This lowering
of the fuel pressure can cause the burner to
lock-out and can sometimes give rise to pulsa-
tions.
Once the following adjustments have been
made, the firing of the burner must generate a
noise similar to the noise generated during oper-
ation. If one or more pulsations or a delay in fir-
ing in respect to the opening of the light oil
solenoid valve occur, see the suggestions pro-
vided on p. 14: causes 34 to 39.
OPERATION
The optimum calibration of the burner requires
an analysis of the flue gases at the boiler outlet
and interventions on the following points.
• 1st and 2nd stage nozzles
See the information listed on page 5.
• Combustion head
The adjustment of the combustion head already
carried out need not be altered unless the 2nd
stage delivery of the burner is changed.
• Pump pressure
12 bar: This is the pressure calibrated in the fac-
tory which is usually sufficient for most pur-
poses. Sometimes, this pressure must be
adjusted to:
10 bar in order to reduce fuel delivery. This
adjustment is possible only if the surrounding
temperature remains above 0°C. Never cali-
brate to pressures below 10 bar, at which pres-
sures the cylinders may have difficulty in
opening;
14 bar in order to increase fuel delivery or to
ensure firings even at temperatures of less than
0°C.
In order to adjust pump pressure, use the screw
5)(A)p. 9.
• 1st stage fan air gate valve
Keep the burner operating at 1st stage by set-
ting the switch 2)(B) to the 1st stage position.
Opening of the air gate valves 6)(A) must be
adjusted in proportion to the selected nozzle:
the index 8)(A) must be aligned with the notch
indicated on the graduated sector 7)(A). This
adjustment is achieved by turning the hex ele-
ment 2)(A):
- towards the right direction (- sign) the opening
is reduced;
- towards the left direction (+ sign) the opening
increases.
• 2nd stage fan air gate valve
Set switch 2)(B) to the 2nd stage position and
adjust the air gate valve 6)(A) by turning the hex
element 4)(A), after having loosened the ring nut
3)(A).
NOTE: in order to facilitate adjustment of hex
elements 2) and 4)(A), use a 3 mm Allen key
5)(A).

BURNER OPERATION
BURNER STARTING (A) - (B)
Starting phases with progressive time intervals
shown in seconds:
• Control device TL closes.
After about 3s:
•0 s : The control box starting cycle begins.
•2 s : The fan motor starts.
•3 s : The ignition transformer is connected.
The pump 3) sucks the fuel from the tank
through the piping 1) and the filter 2) and
pumps it under pressure to delivery. The pis-
ton 4) rises and the fuel returns to the tank
through the piping 5) - 7). The screw 6) closes
the by-pass heading towards suction and the
solenoid valves 8) - 11) - 16), de-energized,
close the passage to the nozzles.
The hydraulic cylinder 15), piston A, opens the
air gate valve: pre-purging begins with the 1st
stage air delivery.
•22 s : Solenoid valves 8) and 16) open and the
fuel passes through the piping 9) and filter 10)
and is then sprayed out through the nozzle,
igniting when it comes into contact with the
spark. This is the 1st stage flame.
•29 s: The ignition transformer switches off.
•36 s: If the control device TR is closed or has
been replaced by a jumper wire, the 2nd stage
solenoid valve 11), energized, opens two pas-
sages: one to piping 12), filter 13), and the 2nd
stage nozzle, and the other to the cylinder 15),
piston B, that opens the fan air gate valve in
the 2nd stage..
The starting cycle comes to an end.
STEADY STATE OPERATION
System equipped with one control device TR
Once the starting cycle has come to an end, the
command of the 2nd stage solenoid valve pass-
es on to the control device TR that controls boiler
temperature or pressure.
• When the temperature or the pressure increas-
es until the control device TR opens, solenoid
valve 11) closes, and the burner passes from
the 2nd to the 1st stage of operation.
• When the temperature or pressure decreases
until the control device TR closes, solenoid
valve 11) opens, and the burner passes from
the 1st to the 2nd stage of operation, and so on.
• The burner stops when the demand for heat is
less than the amount of heat delivered by the
burner in the 1st stage. In this case, the control
device TL opens, and solenoid valves 8)-16)
close, the flame immediately goes out. The
fan's air gate valve closes completely.
Systems not equipped with control device
TR (jumper wire installed)
The burner is fired as described in the case
above. If the temperature or pressure increase
until control device TL opens, the burner shuts
down (Section A-A in the diagram).
When the solenoid valve 11) de-energizes, the
fuel contained in the cylinder 15), piston B, is dis-
charged through the nozzle.
FIRING FAILURE
If the burner does not fire, it goes into lock-out with-
in 5 s of the opening of the 1st nozzle valve and 30
s after the closing of control device TL.
The control box red pilot light will light up.
UNDESIRED SHUTDOWN DURING OPERA-
TION
If the flame goes out during operation, the burner
shuts down automatically within 1 second and
automatically attempts to start again by repeat-
ing the starting cycle.

FINAL CHECKS
• Obscure the photocell and switch off the con-
trol devices: the burner should start and then
lock-out about 5 s after opening of the 1st
stage operation valve.
• Illuminate the photocell and switch off the con-
trol devices: the burner should start and then
go into lock-out after about 10 s.
• Obscure the photocell while the burner is in
2nd stage operation, the following must occur
in sequence: flame extinguished within 1 s,
pre-purging for about 20 ÷ 28 s, sparking for
about 5 s, burner goes into lock-out.
• Switch on control device TL followed by con-
trol device TS while the burner is operating:
the burner should stop.
MAINTENANCE
Combustion. It is required an analysis of the
flue gases at the boiler outlet. Significant differ-
ences with respect to the previous measure-
ments indicate the points where more care
should be exercised during maintenance.
Pump
The pump delivery pressure must be stable at
12 bar.
The depression must be less than 0.45 bar.
Unusual noise must not be evident during pump
operation.
If the pressure is found to be unstable or if the
pump runs noisily, the flexible hose must be
detached from the line filter and the fuel must be
sucked from a tank located near the burner.
This measure permits the cause of the anomaly
to be traced to either the suction line or the
pump.
If the pump is found to be responsible, check to
make sure that the filter is not dirty. The vacuum
meter is installed up-line from the filter and con-
sequently will not indicate whether the filter is
clogged or not. Contrarily, if the problem lies in
the suction line, check to make sure that the fil-
ter is clean and that air is not entering the pip-
ing.
Filters (A)
Check the following filter boxes:
• on line 1) • in pump 2) • at nozzle 3), and
clean or replace as required.
If rust or other impurities are observed inside the
pump, use a separate pump to suck out any
water and other impurities that may have depos-
ited on the bottom of the tank.
Fan. Check to make sure that no dust has accu-
mulated inside the fan or on its blades, as this
condition will cause a reduction in the air flow
rate and provoke polluting combustion.
Combustion head. Check to make sure that all
the parts of the combustion head are in good
condition, positioned correctly, free of all impuri-
ties, and that no deformation has been caused
by operation at high temperatures.
Nozzles. Do not clean the nozzle openings.
Replace the nozzles every 2-3 years or when-
ever necessary. Combustion must be checked
after the nozzles have been changed.
Photocell (B). Clean the glass cover from any
dust that may have accumulated. Photocell 1)
can be removed by pulling it outward forcefully.
Flame inspection window (C) Clean the glass.
Flexible hoses. Check to make sure that the
flexible hoses are still in good condition.
Fuel tank. Every 5 years, or whenever neces-
sary, suck out any water or other impurities
present on the bottom of the tank using a sepa-
rate pump.
Boiler. Clean the boiler as indicated in its
accompanying instructions in order to maintain
all the original combustion characteristics intact,
especially the flue gas temperature and com-
bustion chamber pressure. Lastly, check the
condition of the flue gas stack.
TO OPEN THE BURNER (D)
- Switch off the electrical power
- Loosen screws 1) and withdraw the cover 2)
- Unscrew screws 3)
- Fit the two extensions 4) supplied with the
burner onto the slide bars 5)

BURNER START-UP CYCLE DIAGNOSTICS
During start-up, indication is according to the followin table:
RESETTING THE CONTROL BOX AND USING DIAGNOSTICS
The control box features a diagnostics function through which any causes of malfunctioning are easily identified (indicator: RED LED).
To use this function, you must wait at least 10 seconds once it has entered the safety condition (lock-out), and then press the reset button.
The control box generates a sequence of pulses (1 second apart), which is repeated at constant 3-second intervals.
Once you have seen how many times the light pulses and identified the possible cause, the system must be reset by holding the button
down for between 1 and 3 seconds.
The methods that can be used to reset the control box and use diagnostics are given below.
RESETTING THE CONTROL BOX
To reset the control box, proceed as follows:
-Hold the button down for between 1 and 3 seconds.
The burner restarts after a 2-second pause once the button is released.
If the burner does not restart, you must make sure the limit thermostat is closed.
VISUAL DIAGNOSTICS
Indicates the type of burner malfunction causing lock-out.
To view diagnostics, proceed as follows:
-Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light pulses to tell you the operation is done.
Release the button once the light pulses. The number of times it pulses tells you the cause of the malfunction, according to the coding
system indicated in the table on page 14.
SOFTWARE DIAGNOSTICS
Reports burner life by means of an optical link with the PC, indicating hours of operation, number and type of lock-outs, serial number of
control box etc ...
To view diagnostics, proceed as follows:
-Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light pulses to tell you the operation is done.
Release the button for 1 second and then press again for over 3 seconds until the yellow light pulses again.
Once the button is released, the red LED will flash intermittently with a higher frequency: only now can the optical link be activated.
Once the operations are done, the control box’s initial state must be restored using the resetting procedure described above.
The sequence of pulses issued by the control box identifies the possible types of malfunction, which are listed in the table on page 14.
