WARNING NOTES FOR THE USER HOW TO USE THE BURNER SAFELY
FOREWORD
These warning notes are aimed at ensuring the safe use of the components of heating systems for civil use and the production of hot water. They indicate how to act to
avoid the essential safety of the components being compromised by incorrect or erroneous installation and by improper or unreasonable use. The warning notes provided
in this guide also seek to make the consumer more aware of safety problems in general, using necessarily technical but easily understood language. The manufacturer is
not liable contractually or extra contractually for any damage caused by errors in installation and in use, or where there has been any failure to follow the manufacturer’s
instructions.
GENERAL WARNING NOTES
• The instruction booklet is an integral and essential part of the product and must be given to the user. Carefully read the warnings in the booklet as they contain important
information regarding safe installation, use and maintenance. Keep the booklet to hand for consultation when needed.
• Equipment must be installed in accordance with current regulations, with the manufacturer’s instructions and by qualied technicians. By the term ‘qualied technicians’
is meant persons that are competent in the eld of heating components for civil use and for the production of hot water and, in particular, assistance centres authorised
by the manufacturer. Incorrect installation may cause damage or injury to persons, animals or things. The manufacturer will not in such cases be liable.
• After removing all the packaging make sure the contents are complete and intact. If in doubt do not use the equipment and return it to the supplier. The packaging ma-
terials (wooden crates, nails, staples, plastic bags, expanded polystyrene, etc.) must not be left within reach of children as they may be dangerous to them. They should
also be collected and disposed on in suitably prepared places so that they do no pollute the environment.
• Before carrying out any cleaning or maintenance, switch off the equipment at the mains supply, using the system’s switch or shut-off systems.
• If there is any fault or if the equipment is not working properly, de-activate the equipment and do not attempt to repair it or tamper with it directly. In such case get in touch
with only qualied technicians. Any product repairs must only be carried out by BALTUR authorised assistance centres using only original spare parts. Failure to act as
above may jeopardise the safety of the equipment. To ensure the efciency and correct working of the equipment, it is essential to have periodic maintenance carried out
by qualied technicians following the manufacturer’s instructions.
• If the equipment is sold or transferred to another owner or if the owner moves and leaves the equipment, make sure that the booklet always goes with the equipment so
it can be consulted by the new owner and/or installer.
• For all equipment with optionals or kits (including electrical), only original accessories must be used.
BURNERS
• This equipment must be used only for its expressly stated use: applied to boilers, hot air boilers, ovens or other similar equipment and not exposed to atmospheric agents.
Any other use must be regarded as improper use and hence dangerous.
• The burner must be installed in a suitable room that has ventilation in accordance with current regulations and in any case sufcient to ensure correct combustion
• Do not obstruct or reduce the size of the burner’ air intake grills or the ventilation openings for the room where a burner or a boiler is installed or dangerous mixtures of
toxic and explosive gases may form.
• Before connecting the burner check that the details on the plate correspond to those of the utility supplies (electricity, gas, light oil or other fuel).
• Do not touch hot parts of the burner. These, normally in the areas near to the ame and any fuel pre-heating system, become hot when the equipment is working and
stay hot for some time after the burner has stopped.
• If it is decided not to use the burner any more, the following actions must be performed by qualied technicians:
a) Switch off the electrical supply by disconnecting the power cable from the master switch.
b) Cut off the fuel supply using the shut-off valve and remove the control wheels from their position.
c) Render harmless any potentially dangerous parts.
Special warning notes
• Check that the person who carried out the installation of the burner xed it securely to the heat generator so that the ame is generated inside the combustion chamber
of the generator itself.
• Before starting up the burner, and at least once a year, have qualied technicians perform the following operations:
a) Set the burner fuel capacity to the power required by the heat generator.
b) Adjust the combustion air ow to obtain combustion yield of at least the minimum set by current regulations.
c) Carry out a check on combustion to ensure the production of noxious or polluting unburnt gases does not exceed limits permitted by current regulations.
d) Check the adjustment and safety devices are working properly.
e) Check the efciency of the combustion products exhaust duct.
f) Check at the end of the adjustments that all the adjustment devices mechanical securing systems are properly tightened.
g) Make sure that the use and maintenance manual for the burner is in the boiler room.
• If the burner repeatedly stops in lock-out, do not keep trying to manually reset but call a qualied technicians to sort out the problem.
• The running and maintenance of the equipment must only be carried out by qualied technicians, in compliance with current regulations.

WARNING NOTES FOR THE USER HOW TO USE THE BURNER SAFELY
ELECTRICAL SUPPLY
• The equipment is electrically safe only when it is correctly connected to an efcient ground connection carried out in accordance with current safety regulations. It is
necessary to check this essential safety requirement. If in doubt, call for a careful electrical check by a qualied technicians, since the manufacturer will not be liable for
any damage caused by a poor ground connection.
• Have qualied technicians check that the wiring is suitable for the maximum power absorption of the equipment, as indicated in the technical plate, making sure in
particular that the diameter of cables is sufcient for the equipment’s power absorption.
• Adapters, multiple plugs and extension cables may not be used for the equipment’s power supply.
• An ominpolar switch in accordance with current safety regulations is required for the mains supply connection.
• The electrical supply to the burner must have neutral to ground connection. If the ionisation current has control with neutral not to ground it is essential to make a
connection between terminal 2 (neutral) and the ground for the RC circuit.
• The use of any components that use electricity means that certain fundamental rules have to followed, including the following:
- do not touch the equipment with parts of the body that are wet or damp or with damp feet
- do not pull on electrical cables
- do not leave the equipment exposed to atmospheric agents (such as rain or sun etc.) unless there is express provision for this.
- do not allow the equipment to be used by children or inexpert persons.
• The power supply cable for the equipment not must be replaced by the user. If the cable gets damaged, switch off the equipment, and call only on qualied technicians
for its replacement.
• If you decide not to use the equipment for a while it is advisable to switch off the electrical power supply to all components in the system that use electricity (pumps,
burner, etc.).
GAS, LIGHT OIL, OR OTHER FUEL SUPPLIES
General warning notes
• Installation of the burner must be carried out by qualied technicians and in compliance with current law and regulations, since incorrect installation may cause damage
to person, animals or things, for which damage the manufacturer shall not can be held responsible.
• Before installation it is advisable to carry out careful internal cleaning of all tubing for the fuel feed system to remove any residues that could jeopardise the proper
working of the burner.
• For rst start up of the equipment have qualied technicians carry out the following checks:
• If you decide not to use the burner for a while, close the tap or taps that supply the fuel.
Special warning notes when using gas
• Have qualied technicians check the following:
a) that the feed line and the train comply with current law and regulations.
b) that all the gas connections are properly sealed.
• Do not use the gas pipes to ground electrical equipment.
• Do not leave the equipment on when it is not in use and always close the gas tap.
• If the user of is away for some time, close the main gas feed tap to the burner.
• If you smell gas:
a) do not use any electrical switches, the telephone or any other object that could produce a spark;
b) immediately open doors and windows to create a current of air that will purify the room;
c) close the gas taps;
d) ask for the help of qualied technicians.
• Do not block ventilation openings in the room where there is gas equipment or dangerous situations may arise with the build up of toxic and explosive mixtures.
FLUES FOR HIGH EFFICIENCY BOILERS AND SIMILAR
It should be pointed out that high efciency boilers and similar discharge combustion products (fumes) at relatively low temperatures into the ue. In the above situation,
traditional ues (in terms of their diameter and heat insulation) may be suitable because the signicant cooling of the combustion products in these permits temperatures
to fall even below the condensation point. In a ue that works with condensation there is soot at the point the exhaust reaches the atmosphere when burning light oil or
heavy oil or the presence of condensate water along the ue itself when gas is being burnt (methane, LPG, etc.). Flues connected to high efciency boilers and similar must
therefore be of a size (section and heat insulation) for the specic use to avoid such problems as those described above.

APPLICATION OF BURNER TO BOILER
- Position insulating seal 3 on the sleeve, placing cord 2 between
the ange and the seal.
- slacken screws “6”, adjust the position of connection ange
“5” so that the combustion head penetrates the furnace up to
the length recommended by the generator manufacturer.
- Fasten the burner 4 to the boiler 1 by means of the stud bolts,
washers and the nuts provided 7.
Note:Competely seal the space between the tube unit of the
burner and the hole in the refractory panel using suitable ma-
terials to do so.
ASSEMBLING THE GAS TRAIN
There are different ways of assembling the valve train, 8, 8a and 9
as shown in the drawing. The burner is supplied with the gas train
connection facing downward. If you wish to invert the direction of
train entrance to allow the valve set to be assembled in conguration
9, follow the procedure described in the section entitled: “Preparation
for connection with train turned upward”.
Choose the most rational position for the set-up of the boiler room
and the position in which the gas pipe arrives.

WIRING DIAGRAM
The three-phase power supply line must have a switch with fuses.
The regulations further require a switch on the burner’s power sup-
ply line, outside the boiler room and in an easily accessed position.
For the electrical connections (line and thermostats), follow the
wiring diagram enclosed. To carry out the connection of the burner
to the power supply line proceed as follows:
- Remove the lid by unscrewing the 4 screws (1) in gure 1. In
this way the burner’s electrical panel can be accessed.
- Loosen the screws (2) to remove the cable clamp plate (3),
feed the two 7 and 4 pole pins through the hole as shown in gure
2. Connect the power supply cables (4) to the contactor, fasten
the grounding cable (5) and tighten the relative cable gland. In the
case of a single-phase burner, only the cables L (phase) and N
(neutral) corresponding to positions L1 and L3 as shown in gure
2 are connected to the contactor.
- Reposition the cable oat plate as in gure 3. Turn the cam (6)
so that the oat exerts sufcient pressure on the two cables,
then tighten the screws that fasten the cable oat. Finally, con-
nect the two 7 and 4-pole plugs.
IMPORTANT: the housings for the cables for the 7 and 4-pole
plugs are respectively for cable Ø 9.5-10 mm and
Ø 8.5-9 mm, this to make sure the protection rating
of IP 44 (IEC EN 60529) for the electrical panel.
- To reclose the electrical panel lid, tighten the 4 screws (1) with
a torque of about 5 Nm to ensure the correct seal.
IMPORTANT: only qualied technicians may open the bur-
ner’s electrical panel.

DESCRIPTION OF OPERATIONS AT TWO STAGE
PROGRESSIVE
These burners are of the blown air type which have a mixture of
gas/air at the combustion head. They are suitable for use with
combustion chambers which are either raising high pressure or
reducing pressure, according to the relative work curves. Together
with excellent ame stability, these burners are safe and highly
efcient. It is equipped with a steel ange which slips on the bur-
ner head. When fastening the burner to the boiler it is necessary
to correctly position the ange so that the burner head enters the
combustion chamber to the extent specied by the boiler ma-
nufacturer.The burner has an electronic cam mod. MPA22. The
microprocessor-controlled MPA22 provides intermittent operation,
controls and monitors the electronically-modulated fan-equipped
gas burners and features two (air/gas) adjuster motors. When wor-
king as an automatic burner valve seal control is activated; (for a
better understanding of the MPA 22 read the instructions in the
attached manual, code 0006080905).
Operation of is of the progressive two-stage type, so called becau-
se the switch from primary ame to secondary ame (from mini-
mum to the set maximum) occurs gradually as regards the delivery
of both combustion air and fuel; this gives considerable advanta-
ges in terms of the pressure stability in the gas feed line. Delivery
rate ranges, approximately, from 1 to 1/3. Ignition is preceded by
pre-ventilation of the combustion chamber as per standards, with
the air open: this lasts about 36 seconds. If, at the end of the ven-
tilation stage, the air pressure switch detects that pressure is suf-
cient, the ignition transformer comes on and, after 3 seconds, the
safety and main valves open in sequence. The gas reaches the
combustion head, is mixed with the air being delivered by the fan,
and is ignited. Delivery is regulated by the gas throttle valve. Three
seconds after the (main and safety) valves are opened the ignition
transformer is switched off. The burner is now on at the ignition
point (P0). The ame is detected by the relative control device (an
ionisation sensor positioned inside the ame).The programming
relay goes beyond the shutdown position and powers the air/gas
delivery regulation servomotors, which go to minimum (P1). If the
2nd stage boiler thermostat (or pressure switch) – adjusted by a
temperature or
pressure greater than that in the boiler) allow, the air/gas delivery
servomotors start running and cause a gradual increase is the de-
livery of gas and combustion air until the maximum ow rates to
which the burner has been set have been reached (point P9).
N.B. Electronic cam MPA22 controls the burner by adjusting
the combustion air and gas servomotors according to a pre-
set curve.
The burner remains in the maximum delivery position until the tem-
perature or pressure reaches the limit set for the intervention of the
boiler thermostat (or pressure switch) of the 2nd stage and makes
the servomotors regulating gas/air delivery rotate in the opposite
sense of direction. Thus gas delivery and the relative combustion
air are gradually reduced until they reach minimum value.
Even with delivery at a minimum, if the limit (temperature or pres-
sure at the shut down device (thermostat or pressure switch) has
been regulated is reached, the burner will be brought to a stan-
dstill. When the temperature or pressure drops below the inter-
vention limit set on the shut down device, the burner will star up
again, according to the programme previously described. During
normal operations, the boiler thermostat (or pressure switch) of
the 2nd stage tted to the boiler detects the variations requested
and automatically proceeds with adapting the fuel and combustion
air delivery by inserting the servomotors which regulates delivery
(gas/air). This will rotate in such a way as to obtain an increase or
a decrease. With this manoeuvre, the gas/air delivery regulating
system try’s to equilibrate the quantity of heat supplied to the boiler
with that which the boiler gives to be utilised.
If the ame does not appear within THREE seconds of the opening
of the gas valve, the control box goes to “shut down” (the burner
stops completely and error message 25H) on display. (23)
To “unblock” the equipment press the interference elimination but-
ton for about half a second (24).

electric wiring diagram.
5) Make sure that the combustion head is long enough to
enterthefurnacetotheextentspeciedbytheboilerma-
nufacturer. Check that the device which regulates the air
on the combustion head is in the position considered ne-
cessary for the fuel delivery required (air passage betwe-
en the disk and the head should be considerably reduced
whenthefueldeliveryisreduced;ontheotherhand,when
thefueldeliveryisfairlyhigh,theairpassagebetweenthe
disk and the head should be relatively open). See Chapter
“AirRegulationontheCombustionHead”.
6)Apply a manometer with an adequate scale (if the entity of
pressure forecast allows it is preferable to use a column
ofwaterinstrument,donotuseapointerinstrumentfor
moderate pressure) to the pressure plug on the gas pres-
sure switch.
7) With the I/O (22) switch on the control panel switched to “O”
(0002935870n1) and the master switch turned on, manually
close the remote control switch and check that the motor revol-
ves in the correct direction. If necessary, exchange the position
of the two cables in the line that feeds the motor in order to
invert the rotation direction.
8) Now insert the switch on the command panel. The con-
trolboxreceivesvoltageinthiswayandtheprogrammer
turns on the burner as described in Chapter “Description
of Operations”. To adjust the burner see the “MPA 22”
electronic cam instructions in the attached manual code
0006080905.
9)After adjusting the “minimum”,(P1)bringtheburnerto-
wardsmaximumviathecontrolsontheMPA22keypad.
(see MPA 22 electronic cam instructions in the attached
manual code 0006080905).
10) We recommend that you carry the out combustion tests
with the appropriate instrument at all intermediate points
in the modulation range (from P1 to P9); also check the
gasowdeliveryrateviathemeter.Itisessentialtocheck,
withasuitableinstrument,thatthepercentageofcarbon
monoxide(CO)presentinthefumesdoesnotexceedthe
limitsetbyregulationsatthetimeofinstallation.”
11) Now check automatic mode working of the modulation
(see “MPA 22” electronic cam instructions in enclosed
manual code 0006080905). In this mode the equipment
receives the signal from the electronic modulation adju-
sterRWF40,iftheburnerismodulatingversion,orfrom
the thermostat or the pressure switch second stage if the
burner is progressive two stage.
12) The air pressure switch has the job of bringing the con-
trolboxtoasafetyshutdowniftheairpressureisnotat
thecorrectvalue.Therefore,theairpressureswitchmust
be regulated in such a way as to intervene by closing the
contact (foreseen to by closed while working) when the air
pressureintheburnerhasreachedasufcientlevel.The
pressure switch is self-controlled and therefore it must
close the contact (fan stops and consequently there is an
absenceofairpressureintheburner)ifitdoesnot,the
controlboxwillbeinserted(theburnerremainsatastad-
still).Itmustbespeciedthatifthecontactisnotclosed
duringworking(insufcientairpressure),thecontrolbox
willcarryoutitscycle,buttheignitiontransformerwillnot
be inserted and the gas pilot valves will not open. Con-
sequently,theburner will go to“shutdown”.Checkthat
the air pressure switch functions properly with burner at
minimumdelivery,increasetheregulatingvalueuntilitre-
aches intervention point and the burner should go to shut
down.Tounblocktheburner,pressthespecialpush-but-
tonandreturnthepressureswitchregulatortoasufcient
valueinordertomeasuretheairpressureexistingduring
the pre-ventilation phase.
13) The pressure switches which control the gas pressure
(minimum and maximum) have the job of stopping the
burner functioning when the gas pressure is not within
the values specied. From the specic functions of the

pressureswitches,itisevidentthatthe pressure switch
controls the minimum pressure must make use of the con-
tact,whichisclosed,whenitmeasuresapressurewhich
exceeds that at which it has been set. The maximum
pressureswitchmustmakeuseofthecontact,whichis
closed,whenitmeasuresapressurebelowthatatwhich
ithasbeenset.Theminimumandmaximumgaspressure
switches should be regulated during the burner’s gene-
ral inspection and should be in function with the pressure
found each time. Theintervention (by this we mean the
opening of the circuit) of any one of the gas pressure
switches,willpreventthecontrolboxandthustheburner
fromstartingup.Whentheburnerisoperating(amelit),
the intervention of the gas pressure switches (opening of
the circuit) determines the immediate arrest of the burner.
Duringtheburner’sgeneralinspection,checkthecorrect
functioning of the pressure switches. By operating the
respectiveregulating device,itispossibletocontrolthe
pressure switch’s intervention (opening of circuit) which
causes the burner’s arrest.
14) Check the efciency of the ame detector (ionisation
electrode) by detaching the wire coming from the electro-
deandbyturningontheburner.Thecontrolboxshould
carry out completely its cycle and two seconds after the
ignitioname(pilot)isformed,itshouldgoto“shutdown”.
This control should also be carried out when the burner is
already operating. By detaching the wire that comes from
theionisationelectrode,thecontrolboxshouldgoimme-
diatelyto“shutdown”.
15)Checktheefciencyoftheboilerthermostatsandpres-
sure switches (this should result in the burner coming to
a standstill).
N.B. Check that that ignition takes place correctly because
ifthemixerisforwarditmayhappenthatthespeedofthe
deliveryairissohighthatignitionbecomesdifcult.Ifthis
happensthemixermustbemovedbackbydegreesuntil
itisinapositionatwhichignitiontakesplacenormally,at
whichpointthiscanbetakenasthenalposition.
 Weremindyouthatitisadvisable,asregardstheignition
ame,torestrictthequantityofairtotheminimumneces-
saryforsafeignition,eveninthemostdifcultcases.
MANUAL MODE BURNER INSTRUCTIONS
Combustion control can be carried out over the whole modulation
range while manually controlling the MPA 22 equipment. For this
use modulation connector (B) in the diagram, which is provided
with the burner as standard. After disconnecting the 4-pole plug
(A) which takes the signals from the thermostat or the RWF 40
adjustor, insert the connector in position (B). Use the + button to
increase the gas and air supply or - to reduce it.
After the check, put the 4-pole plug (A) back in so as to reset au-
tomatic mode modulation.
IONISATION CURRENT MEASUREMENT
The current minimum for the working equipment is 1.4 µA.
The burner gives a clearly greater current which will not nor-
mallyrequireanycontrols.If,however,youwishtomeasure
theionisation current,youhavetoconnectamilliammeter
in series with the ionisation electrode cable as shown in the
diagram.

COMBUSTION HEAD AIR ADJUSTMENT
The combustion head has an adjustment device so that the air
passage between the disk and the combustion head is opened
or closed. You are thus able to obtain, closing the passage, high
pressure upstream of the disk even at low capacity. The high
speed and turbulence of the air provides for its greater penetration
into the fuel and therefore an excellent mixture and ame stability.
It may be necessary to have high air pressure before the disk to
prevent ame uctuations, particularly essential when the burner
works on the combustion chamber that is pressurized and/or at a
high thermal load.
It is clear from the above that the device that closes the air to the
blast-pipe must be set at a position such as to always obtain very
high air pressure behind the disk. It is advisable to adjust in such
a way as to obtain a closure of the air at the combustion head that
will require a signicant opening of the air damper that regulates
the aspiration ow from the burner fan. This must of course be the
case when the burner is working at maximum desired supply.
In practice you have to start the adjustment with the device that
closes the air at the combustion head in an intermediate position,
switching on the burner for approximate adjustment as explained
previously.
When the maximum desired supply has been reached, the
position of the device that closes the air at the combustion head is
corrected, moving it forward and backwards, until the right amount
of air is owing to the supply, with the air damper in signicantly
open.

PREPARATION FOR CONNECTION WITH TRAIN TURNED
UPWARD
If you wish to orient the entrance train side upward before applying
the burner to the boiler, proceed as follows.
1) Following the instructions in the section entitled “Maintenance”,
remove the mixer unit and remove the screw (1) connecting the
forward movement rod (2) of the unit with the gas delivery pipe
(3) passing through the slot (4) in the elbow union (gure 1).
2) Turn the elbow union 180° so that the hole in the gas delivery
pipe is aligned with the slot (4a) in the diametrically opposed
position on the union. Connect up the forward movement rod
(2) and the gas delivery pipe (3) with the screw (1) shown in
gure 1.
3) Now remove the 4 nuts (5) in gure 2, dismantle the ame
tube(6) and, after pulling off the lung (7) from its stud bolts, put
it back in position with the threaded connection for anchoring
the gas train turned upward.
4) To complete the operation, anchor the ame tube (6) and the
lung (7) in place with the 4 nuts (5), then put the mixing unit
back in its housing.
You may now install the burner on the boiler with the valve train
layout shown in conguration 9, described in the section on “As-
sembling the gas train”.
