faults in the fuel power supply system;
use of the burner even following an error and/or an irregularity;
repairs and/or overhauls incorrectly carried out;
modification of the combustion chamber with inserts that pre-
vent the regular development of the flame, as structurally
established;
insufficient and inappropriate surveillance and care of those
burner components most subject to wear and tear;
use of non-original components, including spare parts, kits,
accessories and optionals;
force majeure.
the manufacturer furthermore declines any and every re-
sponsibility for the failure to observe the contents of this
manual.
1.2.1 Owner’s responsibility
Please pay attention to the Safety Warnings contained within
this instruction manual. Keep this manual for your records and
provide it to your quali fi ed service agency for use in profession-
ally setting up and maintaining your burner.
Your burner will provide years of ef fi cient operation if it is pro-
fessionally installed and maintained by a qualifi ed service tech-
nician. If at any time the burner does not appear to be operating
properly, immediately contact your qualifi ed service agency for
consultation.
We recommend annual inspection/service of your gas heating
system by a qualifi ed service agency.
Failure to follow these instructions, misuse, or incorrect adjust-
ment of the burner could lead to equipment malfunction and re-
sult in asphyxiation, explosion or fire.
WARNING
Failure to observe the information given in this man-
ual, operating negligence, incorrect installation and
the carrying out of non authorised modifications will
result in the annulment by the manufacturer of the
guarantee that it supplies with the burner.
WARNING

Do not touch any electrical items.
Open all windows.
Close all gas supply valves.
Contact your local gas authority immediately.
• Do not store flammable or hazardous materials
in the vicinity of fuel burning appliances.
• Improper installation, adjustment, alteration,
service or maintenance can cause property
damage, personal injury or death.
• Refer to this manual for instructional or addition-
al information.

Safety and prevention
5 20031446
GB
2.1 Introduction
The burners have been designed and built in compliance with
current regulations and directives, applying the known technical
rules of safety and envisaging all the potential danger situations.
It is necessary, however, to bear in mind that the imprudent and
clumsy use of the equipment may lead to situations of death risk
for the user or third parties, as well as the damaging of the burn-
er or other items. Inattention, thoughtlessness and excessive
confidence often cause accidents; the same applies to tiredness
and sleepiness.
It is a good idea to remember the following:
The burner must only be used as expressly described.
Any other use should be considered improper and therefore
dangerous.
In particular:
it can be applied to boilers operating with water, steam,
diathermic oil, and to other users expressly named by the
manufacturer;
the type and pressure of the fuel, the voltage and frequency of
the electrical power supply, the minimum and maximum deliv-
eries for which the burner has been regulated, the pressurisa-
tion of the combustion chamber, the dimensions of the
combustion chamber and the room temperature must all be
within the values indicated in the instruction manual.
Modification of the burner to alter its performance and destina-
tions is not allowed.
The burner must be used in exemplary technical safety condi-
tions. Any disturbances that could compromise safety must be
quickly eliminated.
Opening or tampering with the burner components is not
allowed, apart from the parts requiring maintenance.
Only those parts envisaged by the manufacturer can be
replaced.
2.2 Personnel training
The user is the person, body or company that has acquired the
machine and intends to use it for the specific purpose. He is re-
sponsible for the machine and for the training of the people
working around it.
The user:
Undertakes to entrust the machine exclusively to suitably
trained and qualified personnel.
Must take all the measures necessary to prevent unauthorised
people gaining access to the machine.
Undertakes to inform his personnel in a suitable way about the
application and observance of the safety instructions. With
that aim, he undertakes to ensure that everyone knows the
use and safety instructions for his own duties.
Must inform the manufacturer if faults or malfunctioning of the
accident prevention systems are noticed, along with any pre-
sumed danger situation.
Personnel must always use the personal protective equipment
envisaged by legislation and follow the indications given in this
manual.
Personnel must follow all the danger and caution indications
shown on the machine.
Personnel must not carry out, on their own initiative, opera-
tions or interventions that are not within their province.
Personnel are obliged to inform their superiors of every prob-
lem or dangerous situation that may arise.
The assembly of parts of other makes, or any modifications,
can alter the characteristics of the machine and hence com-
promise operating safety. The manufacturer therefore
declines any and all responsibility for any damage that may
be caused by the use of non-original parts.

3.8 Firing rate
MAXIMUM OUTPUT must be selected in area A (Fig. 4).
MINIMUM OUTPUT must not be lower than the minimum limit
shown in the diagram:
NOTE:
The firing rate area given in Fig. 4 have been reduced by 10% with
respect to the maximum range that can be reached.
3.8.1 Procedure to refer burner operating condition
in high altitude plants
Find the CORRECTED BURNER CAPACITY for the plant’s alti-
tude in chart 1 and the CORRECTED PRESSURE in chart 2.
Check in the firing rate graph of the burner (Fig. 4), 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 temper-
ature = 68°F, 20°C)
To get the combined correction in case of different air temper-
ature, a compensation of 1000 ft each 20°F (305 m each
11°C) is applicable (100 ft = 2°F).
Example
Rated capacity = 4000 MBtu/hr - Rated air pressure = 1 “WC
Real altitude = 3000 ft - Real temperature = 88 °F
= 88 °F - 68°F (reference temp.) = 20°F (equiva-
lent 1000 ft variation)
Proceeding as descripted above and considering a “virtual altitude”
of (3000 + 1000) ft:
– the corrected capacity is 4567 MBtu/hr
– the corrected burner air pressure is 1.14
Model MBtu/hr GPH
RLS 130/E 1750 12.5
WARNING
The firing rate area values have been obtained con-
sidering an ambient temperature of 68 °F, and an
atmospheric pressure of 394” WC and with the
combustion head adjusted.

3.10 Control box for the air/fuel ratio (LMV36...)
Warning notes
All activities (mounting, installation and service work, etc.)
must be performed by qualified staff.
Before making any wiring changes in the connection area,
completely isolate the plant from mains supply (all-polar dis-
connection). Ensure that the plant cannot be inadvertently
switched on again and that it is indeed dead. If not observed,
there is a risk of electric shock hazard.
Ensure protection against electric shock hazard by providing
adequate protection for the burner control’s connection termi-
nals.
Each time work has been carried out (mounting, installation,
service work, etc.), check to ensure that wiring and parame-
ters is in an orderly state.
Fall or shock can adversely affect the safety functions. Such
units must not be put into operation, even if they do not exhibit
any damage.
Introduction
The control box for the air/fuel ratio (Fig. 6), (hereafter referred to
simply as the control box), that equips the burners, carries out a se-
ries of integrated functions in order to optimise burner functioning,
both for single operation and together with other units (e.g. double
furnace boiler or more than one generator at the same time).
The basic functions carried out by the control box relate to:
flame control;
the dosage of air and fuel via the positioning (with direct servo-
control) of the relative valves, excluding the possible play in
the mechanical cam calibration systems;
the modulation of burner output, on the basis of the load
requested by the system, maintaining the pressure or temper-
ature of the boiler at the working values set;
the safety diagnostic of the air and fuel circuits, via which it is
possible to easily identify any causes of malfunctioning.
Mechanical design
The following system components are integrated in the LMV36...
basic unit:
• Burner control with gas valve proving system
• Electronic air / fuel ratio control
• Control frequency converter air fan
• Modbus interface
Installation notes
• Always run high-voltage ignition cables separately while ob-
serving the greatest possible distance to the unit and to other
cables.
• Do not mix up live and neutral conductors (fire hazard, danger-
ous failures, loss of protection against electric shock hazard,
etc.).
• Do not lay the connecting cable from the LMV36... to the
AZL2… together with other cables.
Electrical connection of the flame detectors
It is important to achieve practically disturbance- and loss-free sig-
nal transmission:
• Never run the detector cable together with other cables.
– Line capacitance reduces the magnitude of the flame signal.
– Use a separate cable.
• Observe the maximum permissible detector cable lengths.
• The ionization probe is not protected against electric shock
hazard. It is mainspowered and must be protected against ac-
cidental contact.
• Locate the ignition electrode and the ionization probe such that
the ignition spark cannot arc over to the ionization probe (risk
of electrical overloads).
WARNING
To avoid injury to persons, damage to property
or the environment, the following warning notes
must be observed!
The LMV36... is a safety device!
Do not open, interfere with or modify the unit.
The manufacturer will not assume responsibili-
ty for any damage resulting from unauthorized
interference!
WARNING
The first start-up, like every further operation for
the internal settings of the control box, requires
access by means of a password and is only to
be carried out by personnel of the Technical As-
sistance Service who have been specifically
trained in the internal programming of the tool.

Warning notes
All activities (mounting, installation and service work, etc.)
must be performed by qualified staff.
Before making any wiring changes in the connection area of
the units, completely isolate the equipment from mains supply
(all-polar disconnection). If not observed, there is a risk of
electric shock hazard.
Ensure protection against electric shock hazard by providing
adequate protection for the connection terminals and by
securing the housing cover.
After any kind of activity (mounting, installation and service
work, etc.), check wiring.
Also ensure that the parameters are correctly set.
Fall or shock can adversely affect the safety functions. Such
units must not be put into operation, even if they do not exhibit
any damage.
Use
The actuators (Fig. 8) are used to drive and position the air damper
and the gas butterfly valve, without mechanical leverages but via
the interposition of an elastic coupling.
They are commanded by the control box, which constantly checks
their position by means of a return signal from the optic sensor in-
side the actuator.
The position (in degrees) of the actuators can be seen on the dis-
play of the Operator Panel.
Index “0” for fuel actuator, index “1” for air actuator.
Installation notes
• Always run the high-voltage ignition cables separate from the
unit and other cables while observing the greatest possible dis-
tance.
• The holding torque is reduced when the actuator is disconnect-
ed from power.

4.1 Notes on safety for the installation
After carefully cleaning all around the area where the burner will
be installed, and arranging the correct lighting of the environ-
ment, proceed with the installation operations.
4.2 Handling
The packaging of the burner includes a wooden platform, so it is
possible to move the burner (still packaged) with a transpallet truck
or fork lift truck.
With regard to the transport in the obligatory passages, refer to
the overall dimensions shown in Fig. 3.
Check also that the area in which you are working is empty and that
there is an adequate escape area (i.e. a free, safe area to which
you can quickly move if the burner should fall).
During the handling, keep the load at not more than 10” from the
ground.
4.3 Preliminary checks
Checking the consignment
4.4 Boiler plate
Drill the combustion chamber mounting plate as shown in (Fig. 9).
The position of the threaded holes can be marked using the gasket
supplied with the burner.
4 Installation
DANGER
All the installation, maintenance and disassembly
operations must be carried out with the electricity
supply disconnected.
WARNING
The installation of the burner must be carried out by
qualified personnel, as indicated in this manual and
in compliance with the standards and regulations of
the laws in force.
WARNING
The handling operations for the burner can be high-
ly dangerous if not carried out with the greatest at-
tention: keep any unauthorised people at a
distance; check the integrity and suitableness of the
available means of handling.
CAUTION
After positioning the burner near the installation
point, correctly dispose of all residual packaging,
separating the various types of material.
Before proceeding with the installation operations,
carefully clean all around the area where the burner
will be installed.
CAUTION
After removing all the packaging, check the integrity
of the contents. In the event of doubt, do not use the
burner; contact the supplier.
The packaging elements (wooden cage or card-
board box, nails, clips, plastic bags, etc.) must not
be abandoned as they are potential sources of dan-
ger and pollution; they should be collected and dis-
posed of in the appropriate places.
WARNING
The output of the burner must be within the boiler's
firing rate;
WARNING
A burner label that has been tampered with, re-
moved or is missing, along with anything else that
prevents the definite identification of the burner
makes any installation or maintenance work diffi-
cult.

4.5 Burner raising
In order to lift the burner, proceed as follows:
screw the two extension bars 1) on the pins 2) (Fig. 10);
place the two plates 3) fix them on the relevant ring nuts 4);
The four burner lifting points are indicated in Fig. 10.
4.6 Blast tube length
The length of the blast tube must be selected according to the indi-
cations provided by the manufacturer of the boiler, it must be great-
er than the thickness of the boiler door complete with its insulation.
The range of lengths available, L (inch), is as follows:
For boilers with front flue passes 13) or flame inversion chambers,
insulation material 11) must be inserted between the refractory 12)
and the blast tube 10).
This protective insulation must not compromise the extraction of
the blast tube. For boilers having a water-cooled front, the insula-
tion 11)-12) (Fig. 11) is not required unless it is required by the boil-
er manufacturer.
4.7 Securing the burner to the boiler
Detach the combustion head from the burner, (Fig. 11):
disconnect the oil pipes by unscrewing the two connectors 6);
loosen the 4 screws 3) and remove the cover 1);
disengage the swivel coupling 14) from the graduated sector;
remove the screws 2) from the slide bars 5);
remove the 2 screws 4) and pull the burner back on slide bars
5) by about 4”;
install the extension bars 31) Fig. 1, page 8 and re-screw the
screws 2) including the safety plate 15);
disconnect the electrode wires and then pull the burner com-
pletely off the slide bars.
