FIRING RATES (A)
The RS 70-100-130 Model burners can work in
two ways: one-stage and two-stage
MAXIMUM OUTPUT must be selected in area A.
In order to utilize also area B (RS 130) it is nec-
essary to perform the calibration of the combus-
tion head as explained on page 6.
MINIMUM OUTPUT must not be lower than the
minimum limit shown in the diagram.
RS 70 = 192 kW
RS 100 = 232 kW
RS 130 = 372 kW
Important
The FIRING RATE value range has been
obtained considering an ambient 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 7.
TEST BOILER (B)
The firing rates were set in relation to special
test boilers, according to EN 676 regulations.
Figure (B) indicates the diameter and length of
the test combustion chamber.
Example:
Output 756 kW:
diameter = 60 cm; length = 2 m.
COMMERCIAL BOILERS
The burner/boiler combination does not pose
any problems if the boiler is CE type-approved
and its combustion chamber dimensions are
similar to those indicated in diagram (B).
If the burner must be combined with a commer-
cial boiler that has not been CE type-approved
and/or its combustion chamber dimensions are
clearly smaller than those indicated in diagram
(B), consult the manufacturer.

GAS PRESSURE
The adjacent tables show minimum pressure
losses along the gas supply line depending on
the burner output in 2nd stage operation.
Column 1
Pressure loss at combustion head.
Gas pressure measured at test point 1)(B), with:
• Combustion chamber at 0 mbar
• Burner operating in 2nd stage
• Gas ring 2)(B)p. 7 adjusted as indicated in
diagram (C)p. 7.
Column 2
Pressure loss at gas butterfly valve 2)(B) with
maximum opening: 90°.
Column 3
Pressure loss of gas train 3)(B) includes: adjust-
ment valve VR, safety valve VS (both fully
open), pressure governor R, filter F.
The values shown in the various tables refer to:
natural gas G20 PCI 10 kWh/Nm
3
(8.6 Mcal/Nm
3
).
With:
natural gas G25 PCI 8.6 kWh/Nm
3
(7.4 Mcal/Nm
3
)
multiply tabulated values by 1.3.
Calculate the approximate 2nd stage output of
the burner thus:
- subtract the combustion chamber pressure
from the gas pressure measured at test point
1)(B).
- Find the nearest pressure value to your result
in column 1 of the table for the burner in ques-
tion.
- Read off the corresponding output on the left.
Example - RS 100:
• 2nd stage operation
• Natural gas G20 PCI 10 kWh/Nm
3
• Gas ring 2)(B)p. 7 adjusted as indicated in
diagram (C)p. 7.
• Gas pressure at test point 1)(B) = 8 mbar
• Pressure in combustion chamber = 3 mbar
8 - 3 = 5 mbar
A 2nd stage output of 825 kW shown in Table
RS 100 corresponds to 5 mbar pressure, col-
umn 1.
This value serves as a rough guide, the effective
delivery must be measured at the gas meter.
To calculate the required gas pressure at test
point 1)(B), set the output required from the
burner in 2nd stage operation:
- find the nearest output value in the table for
the burner in question.
- Read off the pressure at test point 1)(B) on
the right in column 1.
- Add this value to the estimated pressure in
the combustion chamber.
Example - RS 100:
• Required burner output in 2nd stage opera-
tion: 825 kW
• Natural gas G20 PCI 10 kWh/Nm
3
• Gas ring 2)(B)p.7 adjusted as diagram (C)p.7.
• Gas pressure at burner output of 825 kW,
taken from table RS 100, column 1 = 5 mbar
• Pressure in combustion chamber = 3 mbar
5 + 3 = 8 mbar
pressure required at test point 1)(B).
4 + 2 = 6 mbar
pressure required at test point 1)(B).

INSTALLATION
BOILER PLATE (A)
Drill the combustion chamber locking plate as
shown in (A). The position of the threaded holes
can be marked using the thermal screen sup-
plied with the burner.
BLAST TUBE LENGTH (B)
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 range of
lengths available, L (mm), is as follows:
Blast tube 12): RS 70 RS 100 RS 130
• short 250 250 280
• long 385 385 415
For boilers with front flue passes 15) or flame
inversion chambers, protective fettling in refrac-
tory material 13) must be inserted between the
boiler fettling 14) and the blast tube 12).
This protective fettling must not compromise the
extraction of the blast tube.
For boilers having a water-cooled front the
refractory fettling 13)-14)(B) is not required
unless it is expressly requested by the boiler
manufacturer.
SECURING THE BURNER TO THE BOILER (B)
Before securing the burner to the boiler, check
through the blast tube opening to make sure
that the flame sensor probe and the ignition
electrode are correctly set in position, as shown
in (C).
Now detach the combustion head from the
burner, fig.(B):
- loosen the 4screws3) and remove the cover 1)
- Disengage the articulated coupling 7) from
the graduated sector 8).
- Remove the screws 2) from the slide bars 5).
- Remove the two screws 4) and pull the burner
back on slide bars 5) by about 100 mm.
Disconnect the wires from the probe and the
electrode and then pull the burner completely
off the slide bars.
COMBUSTION HEAD CALIBRATION
At this point check, for model RS 130, whether
the maximum delivery of the burner in 2nd stage
operation is contained in area A or in area B of
the firing rate. See page 8.
If it is in area A then no operation is required.
If, on the other hand, it is in area B:
- unscrew the screws 1)(D) and disassemble
the blast tube 2).
- Move the fixing of the rod 3)(D) from position
A to position B, thereby causing the shutter 4)
to retract.
- Now refit the blast tube 2)(D) and the screws 1).
Once this operation has been carried out (if it was
required), secure the flange 11)(B) to the boiler
plate, interposing the thermal insulating screen
9)(B) supplied with the burner. Use the 4 screws,
also supplied with the unit, after first protecting
the thread with an anti-locking product.
The seal between burner and boiler must be air-
tight.
If you noticed any irregularities in positions of
the probe or ignition electrode during the check
mentioned above, remove screw 1)(E), extract
the internal part 2)(E) of the head and proceed
to set up the two components correctly.
Do not attempt to turn the probe. Leave it in the
position shown in (C) since if it is located too
close to the ignition electrode the control box
amplifier may be damaged.

SETTING THE COMBUSTION HEAD
Installation operations are now at the stage
where the blast tube and sleeve are secured to
the boiler as shown in fig. (A). It is now a very
simple matter to set up the combustion head, as
this depends solely on the output developed by
the burner in 2nd stage operation.
It is therefore essential to establish this value
before proceeding to set up the combustion
head.
There are two adjustments to make on the
head:
air and gas deliveries.
In diagram (C) find the notch to use for adjusting
the air and the gas, and then proceed as fol-
lows:
Air adjustment (A)
Turn screw 4)(A) until the notch identified is
aligned with the front surface 5)(A) of the flange.
Gas adjustment (B)
Loosen the 3 screws 1)(B) and turn ring 2) until
the notch identified is aligned with index 3).
Tighten the 3 screws 1) fully down.
Example RS 70:
Burner output = 581 kW (500 Mcal/h).
If we consult diagram (C) we find that for this
output, air and gas must be adjusted using
notch 3, as shown in figs.(A) and (B).
Note
Diagram (C) shows the ideal settings for the
combustion head. If the gas mains pressure is
too low to reach the 2nd stage operation pres-
sure indicated on page 5, and if the ring 2)(B) is
not fully open, it can be opened wider by 1 or 2
notches.
Continuing with the previous example, page 5
indicates that for burner RS 70 with output of
581 kW (500 Mcal/h) a pressure of approxi-
mately 6 mbar is necessary at test point 6)(A). If
this pressure cannot be reached, open the ring
2)(B) to notch 4 or 5.
Make sure that the combustion characteristics
are satisfactory and free of pulsations.
Once you have finished setting up the head, refit
the burner to the slide bars 3)(D) at approxi-
mately 100 mm from the sleeve 4)(D) - burner
positioned as shown in fig.(B)p.6 - insert the
flame detection probe cable and the ignition
electrode cable and then slide the burner up to
the sleeve so that it is positioned as shown in
fig.(D).
Refit screws 2) on slide bars 3).
Secure the burner to the sleeve by tightening
screw 1).
Reconnect the articulation 7) to the graduated
sector 6).
Important
When fitting the burner on the two slide bars, it
is advisable to gently draw out the high tension
cable and flame detection probe cable until they
are slightly stretched.

GAS LINE
• The gas train must be connected to the gas
attachment 1)(A), using flange 2), gasket 3)
and screws 4) supplied with the burner.
• The gas train can enter the burner from the
right or left side, depending on which is the
most convenient, see fig.(A).
• Gas solenoids 8)-9)(B) must be as close as
possible to the burner to ensure gas reaches
the combustion head within the safety time
range of 3 s.
• Make sure that the pressure governor calibra-
tion range (colour of the spring) comprises the
pressure required by the burner.
GAS TRAIN (B)
It is type-approved according to EN 676 Stand-
ards and is supplied separately from the burner
