DESCRIPTION OF PROGRESSIVE TWO-
STAGE OPERATION
Blownairburnerswithelectronicmodulationmaybeusedon
hearthsunderstrongpressureorinadepression,accordingtothe
correspondingoperatingcurves.Theycombineaverystableflame
withtotalsafetyandhighperformance.
TheburnerisequippedwithaLAMTECelectroniccammodel“BT
3xx”controlledbyamicroprocessorwithintermittentoperation,to
controlandmonitorblowergasburnerswithelectronicmodulation
bymeansoftworegulatingmotors(air/gas).Duringoperationas
automaticburner,avalvetightnesscontrolisalsoincorporated.To
betterunderstandtheoperationofthe“BT3xx”electroniccam,read
carefullytheinstructionsintheattachedmanual.
Thetermtwo-stageprogressiveoperationmeansthattransition
fromthefirsttothesecondstageflame(fromminimumto
maximumoperation)isprogressiveintermsofbothamountof
combustiveairsupplyandtheamountoffuel,offeringsignificant
benefitsforthestabilityofpressureinthegassupplynetwork.The
capacityvariationrangethatcanbereachedgoesapproximately
from1to1/3.Ignitionisprecededbythecombustionchamber
pre-ventilation(assetforthbytheStandards),withairopenand
withadurationofapprox.30seconds.Iftheairpressureswitch
hasdetectedaninsufficientpressure,theignitiontransformer
activatesattheendoftheventilationphaseandafter3seconds
thesafetyandmainvalvesopeninsequence.Thegasreaches
thecombustionhead,mixeswithairsuppliedbythefanand
ignites.Thegassupplyisregulatedbythebutterflygasvalve.
Threesecondsafterthevalves(mainandsafety)activate,the
ignitiontransformerswitchesoff.Thustheburnerisignitedat
theignitionpoint( 2).Thepresenceoftheflameisdetected
bythecontroldevice(ionizationprobeimmersedintheflame).
Theprogrammerrelaymovespastthelockingpositionandsends
voltagetotheair/gassupplyregulationservomotors,whichgoto
theminimumpoint(200).Ifthesecondstageboilerthermostat(or
pressureswitch)allowsit(settoatemperatureorpressurevalue
higherthantheexistingvalueintheboiler),theair/gassupplyservo
motorswillstarttoturn,graduallyincreasinggasandcombustion
airsuppliesuptothemaximumsupplytowhichtheburnerhas
beenset(999).
! The “BT 3xx” electronic cam commands the burner,
activating the combustive air and gas servo motor on
the basis of a pre-set curve.
Theburnerremainsinthemaximumsupplypositionuntilthe
temperatureorpressurehasreachedasufficientvaluetocause
the secondstageboiler thermostat(or pressureswitch)to trip,
whichmakestheair/gassupplyregulatingservomotorsturninthe
oppositedirectiontothepreviousone,graduallyreducinggasand
combustiveairsupplytotheminimumvalue.
Ifthelimitvalue(temperatureorpressure)atwhichthestopdeviceis
set(thermostatorpressureswitch)isreachedevenwithgassupply
atminimumlevel,theburnerisshutdownbythedevice.
Astemperatureorpressuredropsbelowtheshut-downdevice’s
setpoint,theburnerwillbeturnedonagainasdescribedabove.
Duringnormaloperationthesecondstageboilerthermostat(or
pressureswitch)appliedtotheboilerdetectsvariationsindemand
andautomaticallyadaptsfuelandcombustiveairsupplies,activating
theair/gassupplyadjustmentservomotorswithincreasingor
decreasingrotation.Thiscausestheair/gassupplycontrolsystem
tobalancetheamountofheatsuppliedtotheboilerwiththeamount
itgivesoffduringuse.
Ifaflamedoesnotappearwithinthreesecondsfromtheopeningof
thegasvalves,thecontrolequipmentwilllockout(shuttingdownthe
boilercompletelyandshowingerrormessage25Honthedisplay(3)).

NATURAL GAS IGNITION AND ADJUSTMENT
1) The air contained in the piping must be bled out,withdue
precautionsandwithdoorsandwindowsopen.Openthepipe
uniononthepipelinesituatedneartheburnerandthenopena
littlethegasshut-offvalve(orvalves).Whenthecharacteristic
odourofgascanbesmelled,closetheshut-offvalve.Waitlong
enoughforthegasintheroomtodisperse,andthenconnect
theburnertothegaspipeagainandopenthevalveagain.
2) Checkthatthereiswaterintheboilerandthatthesystemgates
areopen.
3) Makeabsolutelysurethattheproductsofcombustioncanbe
releasedfreely(boilershuttervalveandflueopen).
4) Makesurethatthevoltageofthepowerlinetowhichtheburner
istobeconnectedcorrespondstothatrequiredbytheburner
andthattheelectricalconnections(motorormainline)are
designedforthevoltageratingavailable.Alsocheckthatall
theelectricalconnectionscarriedoutonsiteareinaccordance
withourwiringdiagram.
5) Makesurethatthecombustionheadislongenoughtoenter
thefurnacetotheextentspecifiedbytheboilermanufacturer.
Checkthattheairadjustmentdeviceonthecombustionheadis
incorrectpositionforthefuelsupplyrequired(theairpassage
betweenthediskandtheheadmustbereducedforlow
supplyandrelativelywidewhensupplyishigher).Seechapter
“Combustionheadairflowadjustment”.
6) Fitapressuregaugewithsuitablefullscale(wherethe
pressurelevelenvisagedallowsit,aliquidcolumnmanometer
ispreferable;donotusepointergaugesforlowpressures)to
thepressureoutletportonthegaspressureswitch.

tostartupasdescribedinchapter“Operationdescription”.For
burneradjustment,refertothesuppliedinstructionsforthe“BT
3xx”electroniccam.
8) Afterhavingadjustedthe“minimum”,(200)bringtheburner
towardsthemaximum,usingthecontrolsonthe“BT3xx”
keyboard.
9) Werecommendyoucheckcombustionusingtheappropriate
instrumentatallintermediatepointsonthemodulationroute(from
200to999),checkingtheflowrateofgasbyreading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inforceatthetime
ofinstallation.
10)Nowchecktheproperautomaticoperationofmodulation.
Thisensuresthattheequipmentreceivesthesignalfromthe
electronicmodulationregulator,iftheburneristhemodulating
model,orfromthesecondstagethermostatorpressureswitch,
ifitisatwostageprogressiveburner.
11)Theairpressureswitchhasthepurposeofswitchingthe
equipmentintothesafety(lock-out)statusiftheairpressureis
notwhatitshouldbe.Thepressureswitchmustthereforebeset
toclosethecontact(closedduringoperation)whenairpressure
intheburnerissufficient.Thepressureswitchconnectioncircuit
isselfcontrolling.Therefore,thecontactwhichismeanttobe
closedinanonoperatingstatus(fanstoppedandthusnoair
pressureinburner),shouldinfactbeinthisstatus,otherwise
thecommand/controlequipmentwillnotbeswitchedon(burner
remainsinoperative).Pleasenotethatifthecontactmeant
tobeclosedduringoperationdoesnotclose(insufficientair
pressure),theequipmentcarriesoutitscyclebuttheignition
transformerisnotswitchedonandthefuelvalvesdonotopen.
Asaresult,theburnerstops.Toverifythattheairpressure
switchisoperatingcorrectly,whiletheburnerisignitedatits
minimumsetting,increasetheadjustmentvalueuntiltheswitch

 Thistestshouldalsobeconductedwiththeburneralreadyon;
theequipmentshould“lock”immediatelywhenthewirefrom
theionizationelectrodeisdisconnected.
14)Checktheproperfunctionoftheboilerthermostatsorpressure

!
Check that ignition occurs normally since if the mixer is
not positioned correctly, it may happen that the speed
of the delivery air is so high that ignition is difficult.
If this happens, the mixer must be shifted back by
degrees until it is in a position in which ignition occurs
normally, and this new position can be regarded as the
final position.
 Rememberthatfortheignitionflame,itisbettertolimitthe
amountofairtotheamountstrictlyindispensabletoensure

(3-4timesinarow),donotinsistbutseekthecauseandsolvethe
problemoraskforassistanceofatechnicianoftheAssistance
Centre.Theburnercanremaininthelockoutpositionindefinitely.
Inemergencycasesitisadvisabletoclosethefuelvalve,andto
disconnecttheburnerelectrically.
MAINTENANCE
Theburnerdoesnotrequireanyparticularmaintenance.However,
itisadvisabletoanalysecombustiongasesandcheckthatthe
emissionvaluesarecorrectonceayear,incompliancewithcurrent
law.Checkthefuelfilter:ifitisdirty,replaceit.Checktheefficiency
oftheionisationelectrode.Thecombustionheadmayneedcleaning.
Duringre-assembly,specialattentionmustbepaidtocentringexactly
theelectrodes(ignitionandflamedetection)inordertoavoidthem
goingtoearthorshort-circuitingwhichwouldresultinthe“lock-out”of
theburner.Themajorityofthecomponentscanbecheckedremoving
thecasing.Tochecktheheadyouhavetodisassemblethemixing
unitfollowtheinstructionsbelow.
1)Undothelidscrew“A”togainaccesstotheinteriorofthe

NOTES ON USE OF PROPANE (L.P.G.)
Wewishtoinformyouofanumberofconsiderationsregardingthe
useofliquidpropanegas(L.P.G.).
1) Approximate assessment of operating cost
a) 1m3ofliquidgasingaseousformhaslesscalorificpower,
about22,000kcal.
b) toobtain1m3ofgasabout2Kgofliquidgasarerequired.This
isequaltoabout4litresofliquidgas.
Thisrevealsthattheuseofliquidgas(L.P.G.)yieldsapproximately
thefollowingequivalence:22.000kcal=1m3(ingaseousform)=
2kgofL.P.G.(liquid)=4lL.P.G.(liquid)fromwhichtheoperating
costcanbeassessed.
2) Safety regulations
Liquidpropanegas(L.P.G.)inthegaseousformhasagreater
specificweightthanair(specificweightrelativetoair=1.56for
propane),whichmeansitdoesnotdisperseinairlikenaturalgas,
whichhasalowerspecificweightthanair(specificweightofnatural
gasrelativetoair=0.60),butprecipitatesandspreadsoutatground
level(asifitwerealiquid).Takingintoaccounttheprincipledescribed
above,theItalianMinistryoftheInteriorsetlimitsontheuseofliquid
propanegasinmemorandumno.412/4183datedFebruary61975,
ofwhichwesumupthemostimportantconceptsbelow.
a)Liquidpropanegas(L.P.G.)burnersand/orboilersmaybeused
onlyinpremiseslocatedabovegroundlevelandcertifiedtowardfree
spaces.Installationsusingliquidpropanegasmaynotbeinstalled

b)Premiseswhereliquidpropanegasisusedmusthaveventilation
openingswhichcannotbeclosedontheiroutsidewallswitha
surfaceareameasuringatleast1/15thesurfaceareaoftheroom,
withaminimumof0.5m2.Atleastonethirdoftheentireareaof

4) Burner
Theburnermustbeorderedspecificallyforusewithliquidgas
(L.P.G.)sothatitisequippedwithgasvalvesofsufficientdimensions
toensurecorrectignitionandgradualadjustment.
Thevalvedimensionisforeseenbyusforasupplypressureof
approximately300mmW.C..Werecommendthatyoucheckthe
burnergaspressureusingawatercolumnpressuregauge.
! Maximum and minimum burner power (Kcal/h) is, of
course, the same as for the original natural gas burner
(L.P.G. has greater heating capacity than natural gas,
which means that to burn completely, it requires a
quantity of air proportionate to the heating power
produced).
5) Controlling combustion
Tolimitconsumptionandavoidserioustrouble,adjustcombustion
byusingtheappropriateinstruments.
Itisabsolutelyessentialtocheckthatthepercentageofcarbon
monoxide(CO)doesnotexceedthemaximumpermittedvalueof
0,1%(useaphialanalyserorothersimilarinstrument).
Thewarrantywillnotcoverburnersburningliquidpropanegas
(L.P.G.)ininstallationsinwhichthesemeasureshavenotbeen
applied.
