the instruction manual is delivered to the user by the system

manufacturer, with the recommendation to keep it in the

room where the heat generator is to be installed.

The instruction manual shows:

– the serial number of the burner;

– the address and telephone number of the nearest

Assistance Centre;

The system supplier must carefully inform the user about:

– the use of the system;

– any further tests that may be required before activating the

system;

– maintenance, and the need to have the system checked at

least once a year by a representative of the manufacturer

or another specialised technician.

To ensure a periodic check, the manufacturer

recommends the drawing up of a Maintenance Contract.

2.2 Guarantee and responsibility

The manufacturer guarantees its new products from the date of

installation, in accordance with the regulations in force and/or the

20145931 6

Safety and prevention

3.1 Introduction

The burners have been designed and built in compliance with

current regulations and directives, applying the known technical

safety rules 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 burner

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.

Specifically:

it can be applied to boilers operating with water, steam,

diathermic oil, and to other uses 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 deliveries for

which the burner has been regulated, the pressurisation of the

combustion chamber, the dimensions of the combustion

chamber and the ambient temperature must all be within the

values indicated in the instruction manual.

Modification of the burner to alter its performance and

destinations is not allowed.

The burner must be used in exemplary technical safety

conditions. 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.

3.2 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

responsible 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;

undertakes to inform his personnel in a suitable way about

the application and observance of the safety instructions.

With that aim, the user undertakes to ensure that everyone

knows the use and safety instructions for his own duties;

Personnel must observe all the danger and caution

indications shown on the machine.

Personnel must not carry out, on their own initiative,

operations or interventions that are not within their province.

Personnel must inform their superiors of every problem 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

compromise operating safety. The manufacturer therefore

declines any and every responsibility for any damage that

may be caused by the use of non-original parts.

In addition:

3 Safety and prevention

ATTENTION

The manufacturer guarantees safety and proper

operation only if all burner components are intact

and correctly positioned.

must take all the measures necessary to

prevent unauthorised people gaining access

to the machine;

the user must inform the manufacturer if

faults or malfunctioning of the accident

prevention systems are noticed, along with

any presumed danger situation;

personnel must always use the personal

protective equipment envisaged by legislation

and follow the indications given in this

manual.

Protection against electrocution from the control box and all

connected electric components is obtained with the correct

assembly.

Before any intervention (assembly and installation

operations, assistance, etc.), ensure the wiring is in order

and that the parameters are correctly set, then make the

safety checks.

Falls and collisions can negatively affect the safety

functions. In this case, the control box must not be operated,

even if it displays no evident damage.

For safety and reliability, comply with the following

instructions:

– avoid conditions that can favour the development of

condensate and humidity. Otherwise, before switching on

again, make sure that the entire control box is perfectly dry!

– Static charges must be avoided since they can damage the

control box’s electronic components when touched.

Use

The control box is a control and supervision system of medium

and large capacity forced draught burners.

If used with the flame detection electrode the system can

operate continuously whereas, with the use of UV sensors it

operates intermittently with stop and restart request at least

once every 24h.

Installation notes

• Make sure that the electrical wiring inside the boiler complies

with national and local safety regulations.

• Do not confuse the powered conductors with the neutral

ones.

• Ensure that spliced wires cannot get into contact with

neighbouring terminals. Use adequate ferrules.

• Arrange the H.V. ignition cables separately, as far as

possible from the control box and the other cables.

• When wiring the unit, make sure that AC 230 V mains voltage

cables are run strictly separate from extra low-voltage cables

to avoid risks of electrical shock hazard.

Technical data

Tab. D

Electrical wiring of the flame detector

It is important for signal transmission to be almost totally free

of any disturbances or loss:

• Always separate the detector cables from the other cables:

– The capacitive reactance of the line reduces the size of the

flame signal.

– Use a separate cable.

• Respect the allowed cable lengths.

• The ionisation probe is not protected against the risk of

electrocution. When connected to the electricity supply, the

ionisation probe must be protected against any accidental

contact.

• Position the ignition electrode and the ionisation probe so

that the ignition spark cannot form an arc on the probe (risk

of electric overcharge).

5.1 Notes on safety for the installation

After carefully cleaning all around the area where the burner is to

be installed, and arranging for the environment to be illuminated

correctly, proceed with the installation operations.

5.2 Handling

The burner packaging includes a wooden platform, it is therefore

possible to handle the burner (still packaged) with a pallet truck

or fork lift truck.

5.3 Preliminary checks

Checking the consignment

Checking the characteristics of the burner

Check the identification label of the burner, showing:

the model (A)(Fig. 8) and type of burner (B);

the year of manufacture, in cryptographic form (C);

the serial number (D);

the data for electrical supply and the protection level (E);

the absorbed electrical power (F);

the types of gas used and the relative supply pressures (G);

the data of the burner's minimum and maximum output

possibilities (H)(see Firing rate)

Warning. The burner output must be within the firing rate of

the boiler;

the category of the appliance/countries of destination (I).

5Installation

DANGER

All the installation, maintenance and disassembly

operations must be carried out with the electricity

supply disconnected.

ATTENTION

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.

DANGER

The combustion air inside the boiler must be free

from hazardous mixes (e.g.: chloride, fluoride,

halogen); if present, it is highly recommended to

carry out cleaning and maintenance more

frequently.

ATTENTION

Burner handling operations can be highly

dangerous if not carried out with the greatest

attention: distance unauthorised personnel, check

integrity and suitability of the means available.

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 handling, keep the load at no more than

20-25 cm from the ground.

After positioning the burner near the installation

point, correctly dispose of all residual packaging,

separating the various types of material.

CAUTION

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

cardboard box, nails, clips, plastic bags, etc.)

must not be abandoned as they are potential

sources of danger and pollution; they should be

collected and disposed of in the appropriate

places.

ATTENTION

A burner label that has been tampered with,

removed or is missing, along with anything else

that prevents the definite identification of the

burner makes any installation or maintenance

work difficult

5.5 Preparing the boiler

5.5.1 Boring the boiler plate

Pierce the closing plate of the combustion chamber, as in Fig. 10.

The position of the threaded holes can be marked using the

thermal insulation screen supplied with the burner.

Tab. F

5.5.2 Blast tube length

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:

Tab. G

For boilers with front flue passes 15) or flame inversion chamber,

a protection in refractory material 13) must be inserted between

the boiler fettling 14) and the blast tube 12).

This protection must not compromise the extraction of the blast

tube.

For boilers with a water-cooled front piece, a refractory lining 13)-

14)(Fig. 11) is not necessary, unless expressly requested by the

boiler manufacturer.

5.5.3 Securing the burner to the boiler

Before securing the burner to the boiler, check (through the

opening of the blast tube) that the probe and electrode are

correctly positioned, as in Fig. 14.

Separate the combustion head from the rest of the burner

(Fig. 11):

loosen the 4 screws 3) and remove the cover 1);

disengage the articulated coupling 7) from the graduated

sector 8);

remove screws 2) from the two slide bars 5);

remove the two screws 4) and pull the burner back on slide

bars 5) by about 100 mm.

Disconnect the probe and electrode cables, then completely

unthread the burner from the slide bars.

ATTENTION

The burner is set up to operate only in

positions 1, 2, 3 and 4 (Fig. 9).

Installation 1 is preferable, as it is the only

one that allows the maintenance operations

as described in this manual.

Installations 2, 3 and 4 permit operation but

make maintenance and inspection of the

combustion head more difficult.

DANGER

Any other position could compromise the

correct operation of the appliance.

The installation 5 is prohibited for safety

reasons.

5.6 Access to head internal part

In order to reach inside the combustion head (Fig. 12) proceed as

follows:

remove the screw 1) and the internal part 2).

5.6.1 Combustion head pre-calibration

For the RS 130/M model, check, at this point, whether the

maximum output of the burner in the 2nd stage is within area A

or in area B of the firing rate.

See "Firing rates” on page 10.

If it is in area A, no intervention is required.

However, if it is in area B:

loosen the screws 1)(Fig. 13) and disassemble the blast

tube 2).

Move the rod 3) (Fig. 13) from position A to position B,

thereby drawing back the shutter 4).

Reassemble the blast tube 2)(Fig. 13) and the screws 1).

Once this operation (if necessary) has been carried out, fix the

flange 11)(Fig. 11 on page 17) to the boiler plate, interposing the

insulating gasket 9)(Fig. 11 on page 17) supplied.

Use the 4 screws, also supplied, after protecting their thread with

an anti-locking product.

5.7 Positioning the probe - electrode

If the probe or electrode is not correctly positioned, you must:

remove the screw 1)(Fig. 12);
