FIRING RATES (A)
RS 68/M LN
During operation, burner output varies between:
• MAXIMUM OUTPUT, selected within area A (and B for
RS 120/M LN model),
• and MINIMUM OUTPUT, which must not be lower
than the minimum limit in the diagram.
RS 68/M LN
RS 120/M LN
Note
In order to utilize also area B (RS 120/M LN) it is necessary to perform the calibration of the combustion head
as explained on page 7.
Important
The FIRING RATE area values have been obtained considering an ambient temperature of 68 °F (20 °C), and
an atmospheric pressure of 394 “WC and with the combustion head adjusted as shown on page 8.
RS 120/M LN
Consult Procedure on page 15 to refer burner operating
condition in high altitude plants.
MINIMUM FURNACE DIMENSIONS (B)
D2793
The firing rates were set in relation to special test boilers.
Figure (B) indicates the diameter and length of the test
combustion chamber.
Example:
Output 2579 MBtu/hr:
diameter = 23.6 inch; length 6.6 ft
COMMERCIAL BOILERS (C) - IMPORTANT
(A)
The RS 68/M LN - RS 120/M LN burners are suitable for
operation on either flame-inversion boilers* or boilers with
combustion chambers featuring flow from the base (three
flue passes) on which the best results are obtained in
terms of low NOx emissions.
The maximum thickness of the boiler’s front door must
not exceed 8” (see fig. C).

(*) For flame inversion boilers, a kit is available to reduce
CO emissions if required.
The kit includes 5 gas pipes, identical to the other 5
already fitted to the burner head. In standard conditions, the burner head is fitted with a second group of
pipes, with gas outlet in a different direction with respect to the others. With this Kit, the second group of
pipes is replaced, so that all the pipes are the same.
After fitting the kit, ensure they work correctly by
measuring the CO and flue gases emissions.
GAS PRESSURE
RS 68/M LN
∆p [“WC]
The adjacent diagrams show minimum pressure losses
along the gas supply line depending on the maximum
burner output operation with natural gas.
Column 1
Gas manifold pressure measured at test point 1)(B),
with:
• Combustion chamber at 0 “WC
• Burner operating at maximum output
• Gas ring 2)(B)p.8 adjusted as indicated in diagram
(C)p.8.
Calculate the approximate maximum 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 diagram for the burner in question.
- Read off the corresponding output on the left.
RS 120/M LN
∆p [“WC]
Example - RS 120/M LN:
• Maximum output operation
• Natural gas
• Gas ring 2)(B)p.8 adjust as indicated in diagram
(C)p.8
• Gas pressure at test point 1)(B)
= 5.11 “WC
• Pressure in combustion chamber = 1.18 “WC
5.11 - 1.18 = 3.93 “WC
A maximum output of 3030 MBtu/hr shown diagrams RS
120/M LN corresponds to 3.93 “WC pressure.
This value serves as a rough guide, the effective delivery must be measured at the gas meter.

COMBUSTION HEAD CALIBRATION
At this point check, for model RS 120/M LN, whether
the maximum delivery of the burner at high fire operation is contained in area A or in area B of the firing
rate. See page 5.
If it is in area A then no operation is required.
If, on the other hand, it is in area B, before starting
the burner remove the 4 circular sectors 1) (D) fastened behind the stabilizing disc by removing the 8
screws 2)(D).
Once this operation has been carried out (if it was
required), secure the flange 11)(B) to the boiler plate,
inserting the gasket 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 airtight.
(D)
D2382
If you noticed any irregularities in the positions of the
flame rod or ignition electrode during the check mentioned
above, remove screw 1)(E), extract the internal part 2)(E)
of the head and 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.

Place the pilot and electrode as shown in fig. (C).
The pilot works correctly at pressures ranging from 5 12” WC.
Important
To set the pilot without main burner operaton, proceed
as follows:
- Move the jumper from terminals "30-V11" to terminals
"30-VP", as given in fig. (F), this way the main valve is
cut out.
- With the burner in the manual position, hold the air
damper in the minimum position and make the setting.
- When the setting is correct, replace the jumper on “30V11”.
COMBUSTION HEAD SETTING
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 MAX
output developed by the burner.
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 delivery R1;
• gas delivery R2.
In diagram (C) find the notch to use for adjusting the air
and the gas, and then proceed as follows:
Air adjustment (A)
Turn screw 4)(A) until the notch identified is aligned with
the front surface 5)(A) of the flange.
IMPORTANT: In order to facilitate adjustment, loosen screw 6)(A), adjust and then
tighten.
D1256
(B)
(A)
Notches (Air=Gas)
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 68/M LN, burner output = 1894 MBtu/hr
If we consult diagram (C) we find that for this output the
adjustments are:
• air:
R1 = notch 6;
• gas:
R2 = notch 2.
Note
Diagram (C) indicates an optimal regulation for a type of
boiler seen in fig. (B) page 5.
If the pressure of gas allows it, by closing ring nut
2)(B) a reduction of the formation of NOx is
obtained.
Maximum burner output
(C)
D2797
Continuing with the previous example, page 6 indicates
that for burner RS 68/M LN with output of 1894 MBtu/hr a
pressure of approximately 2” 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 approximately 4” from
the sleeve 4)(D) ” burner positioned as shown in fig.
(B)p. 7 ” insert the flame rod 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 swivel joint 7) to the graduated sector 6).
(D)
D2376

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 PIPING
• The main 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).
• The gas safety shut-off valves 8)-9)(A) must be as
close as possible to the burner to ensure gas reaches
the combustion head within the safety time range.
• The pilot gas train must be connected to the gas
attachment 5)(A) and can enter the burner from the
right or left side.
GAS TRAIN (B)
It must be type-approved according to required standards and is supplied separately from the burner.

ADJUSTMENTS BEFORE FIRST FIRING
Adjustment of the combustion head, and air and gas
deliveries has been illustrated on page 8.
In addition, the following adjustments must also be
made:
- Open manual valves up-stream from the gas train.
- Adjust the minimum gas pressure switch to the start
of the scale (A).
- Adjust the maximum gas pressure switch to the end
of the scale (B).
- Adjust the air pressure switch to the zero position of
the scale (C).
- Purge the air from the gas line.
Fit a U-type manometer (D) to the gas pressure test
point on the sleeve.
The manometer readings are used to calculate the
MAX. burner power using the diagrams on page 6.
Before starting up the burner it is good practice to adjust
the gas train so that ignition takes place in conditions of
maximum safety, i.e. with gas delivery at the minimum.

MAXIMUM OUTPUT
Using button (B), "increase output" until it locks out, app.
130° (cam 1).
Place the slide switch on MAX and set the relative MAX
trim potentiometer (setting must be very near to 130°) to
exploit as far as possible the variable profile cam 4)(D)
and have the gas butterfly valve on maximum opening,
graduated sector 2) on index 3) fig. (D).
The setting of the gas flow must be made on the gas train
regulator and, if necessary, on the gas valve.
The air setting must be made on the variable profile cam
4)(D) by turning the screws 5), after loosening the screws
6).
MINIMUM OUTPUT
With the slide switch on the OPE position, use button (B)
"decrease output" until it stops at app. 20° (cam 3).
Put the slide switch in the MIN position and set the modulation minimum using the relative MIN trim potentiometer.
Set the air using the variable profile cam 4)(D).
If a lower modulation minimum is required than the level
set on cam 3 of the servomotor (20°), decrease the cam
setting.
INTERMEDIATE OUTPUTS
With the switch (C) in the AUTO position, the slide switch
in the OPE position and the switch 1)(E) in the MAN position, move the button 2)(E) in various intermediate levels between maximum and minimum and set the variable
profile cam 4)(D) to achieve optimum combustion, by
turning the screws 5).
If possible, do not change the previously set maximum
and minimum levels.
Check the various setting levels with a combustion analysis.

AIR PRESSURE SWITCH (A)
AIR PRESSURE SWITCH
Adjust the air pressure switch after having performed all
other burner adjustments with the air pressure switch set
to the start of the scale (A).
With the burner operating at min. output, increase adjustment pressure by slowly turning the relative dial clockwise until the burner locks out.
Then turn the dial anti-clockwise by about 20% of the set
point and repeat burner starting to ensure it is correct.
If the burner locks out again, turn the dial anti-clockwise
a little bit more.
Attention:
As a rule, the air pressure switch must prevent the formation of CO.
To check this, insert a combustion analyser into the
chimney, slowly close the fan suction inlet (for example
with cardboard) and check that the burner locks out,
before the CO in the fumes exceeds 400 ppm.
D2548
(A)
HIGH GAS PRESSURE SWITCH
The air pressure switch may operate in "differential"
operation in two pipe system. If a negative pressure in
the combustion chamber during pre-purging prevents
the air pressure switch from switching, switching may be
obtained by fitting a second pipe between the air pressure switch and the suction inlet of the fan. In such a
manner the air pressure switch operates as differential
pressure switch.
HIGH GAS PRESSURE SWITCH (B)
Adjust the high gas pressure switch after having performed all other burner adjustments with the maximum
gas pressure switch set to the end of the scale (B).
With the burner operating at MAX output, reduce the
adjustment pressure by slowly turning the adjustment
dial anticlockwise until the burner locks out.
Then turn the dial clockwise by 0.8” WC and repeat
burner firing.
If the burner locks out again, turn the dial again clockwise by 0.4” WC.
D2547
(B)
LOW GAS PRESSURE SWITCH
LOW GAS PRESSURE SWITCH (C)
Adjust the low gas pressure switch after having performed all the other burner adjustments with the pressure
switch set at the start of the scale (C).
With the burner operating at MAX output, increase adjustment pressure by slowly turning the relative dial
clockwise until the burner locks out.
Then turn the dial anti-clockwise by 0.8” WC and repeat
burner starting to ensure it is uniform.
If the burner locks out again, turn the dial anti-clockwise
again by 0.4” WC.
D2547
FLAME PRESENT CHECK (D)
The burner is fitted with an ionisation (flame rod) system
which ensures that a flame is present. The minimum
current for reliable operation is 6 µA (see manufacturers
documentation). The burner provides a much higher current, so that controls are not normally required. However, if it is necessary to measure the ionisation current,
disconnect the plug-socket 6)(A)p.4 on the ionisation
probe cable and insert a direct current microamperometer with a base scale of 100 µA. Carefully check polarities.

MAINTENANCE
FLAME INSPECTION WINDOW
Combustion
The optimum calibration of the burner requires an analysis of the flue gases. Significant differences with respect
to the previous measurements indicate the points where
more care should be exercised during maintenance.
Gas leaks
Make sure that there are no gas leaks on the pipework
between the gas meter and the burner.
Flame inspection window
Clean the flame inspection window (A).
Combustion head
Open the burner and make sure that all components of
the combustion head are in good condition, not
deformed by the high temperatures, free of impurities
from the surroundings and correctly positioned. If in
doubt, disassemble the elbow fitting 5)(B).
(A)
Servomotor
Disengage the cam 4)(D)p. 12 from the servomotor and
turn it backwards and forwards by hand to make sure it
moves freely.
D709
OPENING THE BURNER
Burner
Check for excess wear or loose screws in the mechanisms controlling the air damper and the gas butterfly
valve. Also make sure that the screws securing the electrical leads in the burner terminal strip are fully tightened.
Clean the outside of the burner, taking special care with
the swivel joints and cam.
Combustion
Adjust the burner if the combustion values found at the
beginning of the operation do not comply with the regulations in force, or do not correspond to good combustion. Record the new combustion values; they will be
useful for subsequent controls.
D2378
(B)
TO OPEN THE BURNER (B):
- Switch off the electrical power.
- Loosen screws 1) and withdraw cover 2).
- Disengage the swivel joint 7) from the graduated sector 8).

PROCEDURE TO REFER BURNER OPERATING CONDITION IN HIGH ALTITUDE PLANTS
-
Find the corrected burner capacity for the plant’s altitude in chart 1 and the corrected pressure in chart 2.
Check in the firing rate graph of the burner (page 5), if the working point defined by the values above is within the range limits.
If not, higher burner size is needed.
Note
Charts are based only on altitude variation
(reference temperature = 68°F , 20°C)
To get the combined correction in case of different
air temperature, a compensation of 1000 ft each
20°F (305 m each 11°C) is applicable.

Example
Rated capacity = 3000 MBtu/hr - Rated air pressure = 1.5”w.c.
Real altitude = 5000 ft - Real temperature = 108°F
∆ = 108°F - 68°F (reference temp.) = 40°F (equivalent 2000 ft variation)
Proceeding as descripted above and considering a “virtual altitude” of (5000 + 2000) ft:
- the corrected capacity is 3847 MBtu/hr;
Burner RS 120/M LN is OK
- the corrected burner air pressure is 1.92.

BURNER OPERATION
LFL 1.335 Series 01
BURNER STARTING
• Load control close.
Fan motor starts.
• Servomotor starts:
130° rotation to right, until contact is made on cam
1)(A) page 12.
The air damper is positioned to MAX. output.
• Pre-purge stage with air delivery at MAX. output.
• After pre-purge stage, servomotor rotates to left up to
the angle set on cam 3)(A) page 12 for MIN. output.
• The air damper and the gas butterfly are positioned to
MIN. output.
• Ignition electrode strikes a spark.
• Pilot valve opens. The pilot flame is ignited.
• After about 12 s the main flame ignites and starting
cycle ends.
Full Modulation
(A)
D2273
Low - High
STEADY STATE OPERATION
At the end of the starting cycle, the servomotor control
then passes to the load control for boiler pressure or
temperature.
(The control box continues, however, to check that the
flame is present and that the air pressure switch is in the
correct position.)
• If the temperature or pressure is low, the burner progressively increases its output to the MAX. value.
• If the temperature or pressure is high, the burner progressively decreases its output to the MIN. value.
And so on.
• The burner locks out when demand for heat is less
than the heat supplied by the burner at min. output.
Load control opens. The servomotor returns to the 0°
angle limited by contact with cam 2. The air damper
closes completely to reduce thermal dispersion to a
minimum.
Every time output is changed, the servomotor automatically modifies gas delivery (gas butterfly valve) and air
delivery (fan air damper).
Switching times are given in seconds, in the burner startup sequence.

If the flame should accidentally go out during operation,
the burner will lock out within 1s.

BURNER FAULTS
Control program under fault
conditions and lock-out
indication
LFL 1.335 Series 01
In case of any disturbance, the sequence mechanism stops and with it the lock-out indicator. The symbol
above the reading mark of the indicator gives the type of disturbance:
No start, e.g. because one contact is not closed. Lock-out during or after control program sequence
due to extraneous light (e.g. non-extinguished flames, leaking fuel valves, defects in the flame
supervision circuit, etc.)
Interruption of startup sequence, because the OPEN signal has not been delivered to terminal 8
by limit switch “a”. Terminals 6, 7 and 14 remain under voltage until the fault has been corrected!
P
Lockout, because there is no air pressure indication at the beginning of air pressure control.
Every air pressure failure after this moment in time leads to lock-out, too!
Lock-out due to a fault in the flame supervision circuit.
Interruption of startup sequence, because the position signal for the low-flame position has not
been delivered to terminal 8 by auxiliary switch “m”. Terminals 6, 7 and 14 remain under voltage
until the fault has been corrected!
1
Lock-out, because no flame signal is present after completion of the (1st) safety time.
2
Lock-out, because no flame signal has been received on completion of the 2nd safety time (flame
signal of the main flame with interrupted pilot burners).
Lock-out, because the flame signal has been lost during burner operation.
If lock-out occurs at any other moment in time between the start and the pre-ignition which is not marked by
a symbol, this is usually caused by a premature, i.e. faulty flame signal, e.g. caused by a self-igniting UV
tube.

NOTES
• For electrical connection use flexible cables according to local Regulations.
• The setting of the thermal overload must be according to the total burner amperage draw.
• The RS 68/M LN - RS 120/M LN burners leave the factory preset for:
- 208-230 V power supply: only in this case, if 460 V power supply is required, change the fan motor connection from delta to star and change the
setting of the thermal overload as well;
- or 575 V power supply;
depending on the burner model (see page 3).
• The RS 68/M LN - RS 120/M LN burners have 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 check 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 fitted in series to IN to provide for burner shut-down at least once every 24 hours.
Important note
When installing for the first time and after any maintenance work, make sure the gas valves are connected properly to the orange terminals
before proceeding to ignite the burner. Insert auxiliary lamps or check, with the aid of a tester, that power is not being supplied to the valves
during standby or pre-purging. Burner ignition with the gas valves open during pre-purging may cause an explosive condition.
