2.1 Introduction
The burners have been designed and built in compli-
ance 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, dia-
thermic oil, and to other users expressly named by the manu-
facturer;
the type and pressure of the fuel, the voltage and frequency
of the electrical power supply, the minimum and maximum
deliveries for which the burner has been regulated, the pres-
surisation 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 desti-
nations 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 unauthor-
ised 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 equip-
ment 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 Control box for the air/fuel ratio (LMV51...)
Warning notes
To avoid injury to persons, damage to property
or the environment, the following warning notes
must be observed!
The LMV51... is a safety device!
Do not open, interfere with or modify the unit.
Riello S.p.A. will not assume responsibility for
any damage resulting from unauthorized interfer-
ence!
Risk of explosion!
Incorrect configuration can lead to excessive fuel
supply which might cause an explosion!
Operators must be aware that incorrect settings
made on the AZL5… display and operating unit and
incorrect settings of the fuel and / or air actuator
positions can lead to dangerous burner operating
conditions.
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 LMV5..., completely isolate the plant from mains supply
(all-polar disconnection). 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.
Protection against electrical shock hazard on the LMV5... and
on all connected electrical components must be ensured
through appropriate mounting.
Each time work has been carried out (mounting, installation
and service work, etc.), check to ensure that wiring is in an
orderly state, that the parameters have been correctly set and
make the safety checks.
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.
In programming mode, the position check of actuators and
VSD (checking electronic fuel / air ratio control) is different
from the check during automatic operation.
Like in automatic operation, the actuators are still jointly
driven to their required positions. If an actuator does not
reach the required position, corrections are made until that
position is reached. However, in contrast to automatic opera-
tion, there are no time limits to these corrective actions.
The other actuators maintain their positions until all actuators
have reached the positions currently required.
This is essential for setting fuel /air ratio control.
This means that during the time the fuel / air ratio curves are
programmed, the person making the plant settings must con-
tinuously monitor the quality of the combustion process (e.g.
by means of a flue gas analyzer).
Also, if combustion levels are poor, or in the event of danger-
ous situations, the commissioning engineer must take appro-
priate action (e.g. switching off manually).
To ensure the safety and reliability of the LMV5... system, the
following points must also be observed:
– Condensation and ingress of humidity must be avoided. Should
such conditions occur, make sure that the unit will be completely
dry before switching on again!
– Static charges must be avoided since they can damage the
unit’s electronic components when touched.
Mechanical design
The LMV5... is a microprocessor-based burner management sys-
tem with matching system components for the control and supervi-
sion of forced draft burners of medium to large capacity.
The following components are integrated in the basic unit of the
LMV5...:
• Burner control with gas valve proving system
• Electronic fuel / air ratio control with a maximum of 4 (LMV51…)
or 6 (LMV52…) actuators
• Optional PID temperature / pressure controller (load controller)
• Optional VSD moduleMechanical design
Installation notes
• Ensure that the electrical wiring inside the boiler is in compliance
with national and local safety regulations.
• Do not mix up live and neutral conductors.
• Make certain that strain relief of the connected cables is in com-
pliance with the relevant standards (e.g. as per DIN EN 60730
and DIN EN 60 335).
• Ensure that spliced wires cannot get into contact with neighbor-
ing terminals. Use adequate ferrules.
• Always run high-voltage ignition cables separately while observ-
ing the greatest possible distance to the unit and to other cables
• The burner manufacturer must protect unused AC 230 V termi-
nals with dummy plugs (refer to sections Suppliers of other ac-
cessory items).
• When wiring the unit, ensure that AC 230 V mains voltage ca-
bles are run strictly separate from extra low-voltage cables to
warrant protection against electrical shock hazard.

Technical description of the burner
Electrical connection of ionization probe and flame detector
It is important to achieve practically disturbance- and loss-free
signal transmission:
• Never run the detector cables together with other cables:
– Line capacitance reduces the magnitude of the flame signal.
– Use a separate cable.
• Observe the permissible cable lengths.
• The ionization probe is not protected against electrical shock
hazard. The mainspowered ionization probe must be protected
against accidental 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).

3.9 Actuators
Warning notes
To avoid injury to persons, damage to property
or the environment, the following warning notes
should be observed!
Do not open, interfere with or modify the actua-
tors!
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 actuator, completely isolate the burner control from the
mains supply (all-polar disconnection).
Ensure protection against electric shock hazard by providing
adequate protection for the connection terminals and by
securing the housing cover.
Check to ensure that wiring 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.
The housing cover may only be removed for
short periods of time for wiring or when making
the addressing.
It must be made certain that dust or dirt will not
get inside the actuator while such work is carried
out.
Use
The actuators (Fig. 9) are used to drive and position the air
damper and the gas butterfly valve, without mechanical leverag-
es but via the interposition of an elastic coupling.
When used in connection with burner controls or electronic fuel
/ air ratio control, the associated controlling elements are con-
trolled depending on burner output.
Installation notes
• Always run the high-voltage ignition cables separate from the
unit and other cables while observing the greatest possible dis-
tance.
• To ensure protection against electric shock hazard, make cer-
tain that the AC 230 V section of the actuator is strictly segregat-
ed from the functional low-voltage section.
• The holding torque is reduced when the actuator’s power supply
is switched off.
When servicing or replacing the actuators, take
care not to invert the connectors.
