Takeappropriateactions
Products should bestored in adry, cool or dry conditioned places . Storagelifeof our products
(servicelife) is 10 years.

04.12.2020 Rev. 00 5
Beforecommissioning and If thereis pressureloss in thesystemdueto seasonal
maintenance; Afterwateraddition process, it is necessary tocarry out thatthereis
absolutely noair in thesystemand Airremoval must beobserved and deaeration must be
repeated until you are surethat thereis noairinthesystem.
Preventingdamagecausedby the presenceof particlessuchasdirt, sediment, metal burrs on the
heating circuit installation and condensing boiler,for thecomfortableand longer servicelife of the
boilers, It isrecommendedthat theinstallationcircuit should bePeriodicallytakeninto
maintenance plan between 6 months – 1 year period.
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.

5. 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

requirements.
In orderto prevent sedimentation, propertiesof thewatertobeusedor to bereinforcedinthewaterline
should not exceed thefollowing tablevalues according to below mentioned capacities.

5. Thecustomer or contract company should analyzethewater to beused in thewater lineby an
accreditedorganization prior tocommissioning and awater quality report should provided
containingMinimumHardness, pH and conductivity values, total dissolved solid values .
6. pHvalueof unrefinedwater must be7<pH<9. This pHvaluecanbeachieved after fillingthe

8. INSTALLATION
8.1. GeneralControls
ØTheheating capacityof thedevice shouldbedetermined basedon theheat requirement calculate
ØAll parts necessary for thesystemmust beavailable.
ØMakesurethatall protection and safety devices areavailable.
ØIn order toprevent accumulation of dirt in thesystem,prevention of boiler operation and damage
given to theboilerby clogging, afiltermust bemounted onto thesystem’s return pipe.
ØThedevicehas afrost protection systemto prevent thedevicefromfreezing when thewater
temperatureof theinstallationfalls below +4 ˚C.
ØEnsurethat thegas connections aremadewith pipes confirming to thestandards,and that thereis
no leakageon theseconnections.
ØEnsurethat theelectricconnections areproper.
Cleantheinsideof fuellinethoroughly beforeinstalling theburnerto thefuelline.Any damagethat
mayoccur dueto solid objects and metalparticlesfromthefuellineshall not becoveredby our
company.
ElectricalConnection
Performelectrical connections according to thediagramprovided. Follow generalsecurity rules
during installation of electricwiring andmaking connections. Connect theearthing terminal in
electricpanel to theearthing installation.
In ordertokeepthepH valuein balance,passingthewatercirculatingin thesystemthrough asoftening
step (Reverseosmosis systems)will beuseful in thecontinuity of thewater quality.

04.12.2020 Rev. 00 14
8.2. Assemblyof Condensing FluidDrain
1. Ensurethat siphon is fully filled with water beforeactivation of boiler.
2. Drain direction mustallow flow of condensing fluid. Drainpipemustbeplannedto prevent any
clogging dueto external effectlikefrost, etc. Drain parts must beplastic.
3. Boilercondensing outlet must beatleast 13 mm.
Condensing drain must not bechangedor cloggedafterassembly. Clogging ofcondensing drain
causestheboilerto automatically shut down or causesthesiphon to overflow. Itwill behelpful to
pour somehot waterto theopenparts of drain if thereis apossibility offrost. Drain must beopen
at all times to ensureproper functioning of theboiler.

04.12.2020 Rev. 00 15
9. ECODENSE CONTROL INSTRUCTIONSBEFORE START-UP
1. Ensurethatboileraremountedon fixed, firmandrobust wall. Usemetalhangers on improper
walls.
2. Closed circuit maximumoperation pressureis 3 bars.
3. Safety valvefixedto 3 bars must beused.
4. Ensurethat stackconnections, areat right radius and connected as leakproof.
5. PWMpumphasitsautomaticair vent. Itis suggestedthatairvent must beusedon CH circuit for
safety.
6. Hydrauliccircuit pressureis displayedon controlcard display. Checkthesystemwaterpressure
on thedisplay.
7. Control ifthecondensing fluid siphon is madeof plastic,isolatedagainst frost,atcorrectradius
and connectedto condensing fluid drain with an angle. It should not beconnectedto rain drain.
8. Ensurethatgaspressurecomplieswith boileroperation instructions. In situations wheregas
pressureis higher than required pressure, aregulator must beused.
9. Ensurethatsensorson boilerfeedandcircuit (outgoing-return temperature,ambienttemperature,
boilertemperaturesensors, roomthermostats and theother control kit ) arewired correctly.
10. In caseof an imbalance in electricalinstallation’s voltagevalue, It is recommended to install a
voltageregulator of 1 kw, up to 550 kw capacity and 2 kw; for capacities over 550kw in order not
to damagetheelectroniccard on thedevice.
11. In theregions with cold and minus winter conditions, only PropyleneGlycol containing Anti-
freeze liquid is allowed to useas afrost protection liquid for boilers, Content suitability
It is advised to interview with themanufacturerabout Suitableliquidcontent.
On first start-up if thereis deficiency in thesystemdetectedby ECODENSE authorized service
technicians, technicians arenot allowed to activatethesystem.

9.3. Operating Principle
Theboilercan besetin 2 operations modes:-‘Summer’ (DHW only), ’Winter’ (CH & DHW) ,
Winter Mode(CH & DHW)
1. Press the ON/OFF button (K5). Radiator and tapsymbol will bedisplayed on thescreen.
2. CH waterset temperaturewill bedisplayed on thescreen when DHWis not needed.CH heating
settemperatureis increasesbypressing (K1)button, and decreasesbypressing (K2)button.CH
settemperatureis displayedonthescreenwhenpressedtothesebuttons. Flamesymbol ( )is
displayedon thescreenwhencondensingboilerisstarted-up. Theradiator symbol on thescreen
will beflashing when condensing boilerworks at CH mode.
3. DHWsettemperatureis increasedby pressing to (K7)button, and decreasedby pressing (K6)
button. DHWsettemperatureis displayedon thescreenwhenpressedto thesebuttons. Whenthe
DHWis needed, condensing boileris workedon DHWmodeand tapsymbol will beflashing
whencondensing boilerworksatDHWmode.Becauseof theDHWpriority, evenif theappliance
is operating at CH, condensing boiler will switch towhen DHWis needed.
Summer Mode( DHW only)
1. Press the ON/OFF button (K5) until thetap symbol will bedisplayed on thescreen.
2. DHWheating set temperatureis increases by pressing (K7) button, and decreases by pressing
(K6) button. DHWset temperatureis displayed on thescreenwhen pressed to thesebuttons.
condensing boiler will startedat DHWmodewhen DHWis needed.
9.4. BoilerFrost ProtectionMode
When water outlet temperaturedecreased below 5°C, frost protection function ofcondensing boiler
operating systemprovides that burner starts up and increases water outlettemperatureup to 30°C.
Frost protection modeworks under theconditionsbelow:
1. Condensing boilerelectricalsupply should beturned on.
2. Main gas valveon gas circuit should beopened.
3. Hydraulicwater pressureshould beadjusted properly.
Condensing boiler should not bebloked.
