organizations on thedevice.
•All operation, commissioningand installation works (except for burning adjustment) should be
carriedout whenthedeviceis notoperatingand afterdisconnecting thepowersupply.
Noncompliancewiththeserulesmayleadtoserious bodilyinjuriesand evendeathby electrical
shocks or uncontrolled flameformation.
•Repairs concerned with safety elements should becarried outonly by themanufacturing company.

Beforecommissioning and If thereis pressureloss in thesystemdueto seasonalmaintenance;
Afterwateradditionprocess, it is necessary to carry out that airremoval process and must be
observedthatthereisabsolutely noair in thesystem. If there is airin thesystemrepeatthe
deaerationprocess.
If you receieve 110 (Lock-out) failure on thecontrol panel, pleasedo no reset theboiler, Call
AuthorisedService company.
Preventing damagecaused by thepresence of particles suchas dirt, sediment, metal burrs on the
heating circuit installation and condensing boiler, for thecomfortableand longerservice lifeof
theboilers, It is recommended that theinstallation circuit is separated by plateheat exchanger as
primary and secondary circuit
For TheHigh-riseBuildings, If height ofstructuremorethan 25 mt. Or morethan 10 th floor, in
order to ensurethatcondensing boilercascadesystemoperates comfortably atlow pressures, a
plateheatexchangermust beinstalled inorder to distinguish thehigh pressurebetween 2nd
circuit andthePrimary circuit. thestaticpressureappearanced dueto theheight of building,theboiler
systemis not allowed to operateundertheinfluence of high pressure.
BOILER ROOM
Condensing Boilers must beinstalled in asuitableroom/floor with minimumexternal air openings
and sufficient to ensureoptimumgas-air mixturecombustion, in compliancewiththeregulations.
Air openings of theboilerroom, burner fan intakevents or air ductsmust stay open to the
atmosphereand Birdcageshould beinstalled in order to prevent any Bird, foreignbody entrance
a.Thebuild up of toxic/explosivegasmixtures in theboiler room,
b. Combustion with insufficient air,resulting in hazardous, anti-economical and polluting ope-
ration.
TheCondensing boiler must bealways protected fromrain, snow and frost to prevent corrosion and
paint deformations.
Keepthecondensing boiler roomclean and free of solidvolatilesubstances,which could besucked
into thefan and clogtheinternal boiler or combustion air ducts.
Every 6-12 months, afterfirst commissioning of boiler, theboiler devices should becleaned with
protectivechemicals to prevent calcification and resultant blocking and corrosion on themetallic
surfaces.
Flushing;
On theCurrently operating systems, appropriatechemical solution with thepH rangeof 4-6 should be
selected for cleaning thepipelineinstallation for safety commissioning thecondensing boiler.
In thenewbuilding installations and boiler heat exchangers, maintenance should beappliedwith
chemicals with neutral pH (neutral) effectand preventivemaintenance must becarried out periodically.

ØBoilers and heating zones operateundersuitablewater flow.
Sizing of Balance Tank:
ØIn order toensurehealthy operation of thebalancetank, accuratesizingmust bemade.
ØTheboiler’s exit water temperatureshould bemeasured on theupper part of balance tank.
ØFor this, a½”muff should bewelded onto tank, and also an air reliefcock should bemounted.

5.3. ExpansionTank
Expansiontank forepressures must beadjusted according tosystem. Expansion tank should be
placed parallel to circuit returnline.
5.4. Manometer
Amanometer with capacity of at least 0 to 6 barmust beconnected to system. Manometer should be
placed to easily visiblespot fromfilling point, preferably samepoint as expansion tank.
5.5. Strainer
Any dirt or residuein circuitwatercausesdamagegot boilerand circuit components and decreases
efficiencyby reducing heattransfer. Inorderto prevent this problemastrainermust beconnectedto
circuit.
5.6. AirSeparator
Theair inthewaterdissolvesdueto increasing temperatureand flowin thecircuit. Dissolvedaircauses
cavitation,sound and efficiency loss. By using an air separator air is removed fromthesystem.
Thehydraulicsystemdesign must comply with thecircuit diagramsspecified in theusermanual to ensure
that thesystemoperates smoothly and that installation errors do not result in loss of efficiency. The
hydraulicsystemmust haveabalance vessel, sediment trap, air separator and expansion tank in
accordancewith thesystemcapacity andspecifications.
In ordertokeepthepH valuein balance,passingthewatercirculatingin thesystemthrough asoftening
step (Reverseosmosis systems)will beuseful in thecontinuity of thewater quality.

14.12.2021 Rev. 03 17
6. WATER QUALITY
1. Beforeconnection of condensing boilers any dirt and residuein circuit must becleaned.
2. Water Hardness and pH measurements should bemadeby theauthorized or central servicein the
field wheretheboiler will becommissioned before thecommissioning, and it should bedecided
whether thewater can beusedin theboiler water installation.
3. Refined water must beused whileadding water to heating circuit duetoany loss in closed circuit.
4. Permittedwaterhardness for thewaterusedin watercircuit must comply with Frenchor German
(VDI 2035) hardness degree standards.Thelimedissolvedin water,settlesonhot surfacesand
formsaninsulationlayerwhenwatertemperaturerises. This prevents heattransferand high
temperaturemight damagetheheatexchanger.If boilerwatercyclesthroughwatercircuit, all
circuit watermust meetaboverequirements.If aplateheatexchangerseparatesboilerwaterand
heating circuitwater, onlythewaterbetweenboilerand heatexchangermust meetthese
requirements.
In ordertoprevent sedimentation, propertiesof thewatertobeusedor to bereinforcedin the
water lineshould not exceed thefollowing tablevalues according to below mentioned capacities.

organicsolutions with achemical pH effect [neutral].
8. Prior to commissioning of condensing boilers inold buildingwaterinstallations,asuitabletypeof
