IBC SL 26-260 G3 Quick Start Guide

Iftheburnerdoesnotlight,theprocessisrepeateduntiltheburnerlightsandflameisdetected.After3trialsfor
ignition,theboilerlocksoutandwillneedtobemanuallyresetbyclearingtheerroronthetouchscreencontroller
(Diagnostics>AdvancedDiagnostics>ClearErrors).Theboilerautomaticallyresetsafter60minutes,ifnoaction
istaken.
To perform a combustion test and adjustment:
1. Turnofftheboiler’sgasshut-offvalve.
2. Withasmall(1/8"or3mm)flatscrewdriver,opentheinletgassupplypressuretestportbyturningitscenter-
screw1fullturncounterclockwise.
3. Attachamanometertotheinletpressuretestportandturnongastoappliance.
Staticmanometerreadingshouldbeideally7"w.c.forNaturalGasand11"w.c.forPropane.
Minimumandmaximumstaticpressureshouldbebetween5"and14"w.c.Monitorpressure
throughoutthecommissioning(start-up)procedure.Pressuremaydropupto1"to2"w.c.athighfire.
4. Beforeyouchangetheloadtomanualcontrol,notetheloadsetting.
5. Settheloadtomanualcontrol,andsettheheat-outvaluetothemaximumMBHfortheboiler.Thisload
shouldbelargeenoughtoallowtheboilertooperateathighfireforover10minutes.
6. Withacombustionanalyzerprobeinthefluegastestport,checkthefluegasreadingandadjustthegas:air
ratioscrewtobringthefluegastowithintheparametersindicatedinTable 1 .
7.
Adjustslowly(clockwise)theHighFire(Gas:AirRatioAdjustment)screwtoobtainthecorrectCO
2
value
(seeTable 1 ).Maketinyadjustments(mayrequireseveralturns).TurningtheHighFire(Gas:AirRatio
Adjustment)screwclockwisewillleanouttheflame.
 Note
Clockthegasmeter(seeinstructionsonPage6)toconfirmfullmaximumratingplateinput.
CheckthemeasuredresultswithTable2.
8. Settheheat-outvalueinmanualmodetotheminimumMBHfortheboiler(seeTable 1 ).
9. WhiletheboilerisatLowFire,comparethecombustionreadingagainstthereadinginTable2.Thereading
shouldbewithintherangelisted.
10. Restoretheloadtothepreviousloadtype.Alltheprogrammedsettingswillberestoredandtheloadwill
operateasbefore.Confirmasmoothignitionsequence.
11. Turnoffthegassupplyatthegasshut-offvalve.
12. Disconnectthepowertotheboiler.
13. Disconnectthemanometer.
14. Closethegassupplytestportscrewbyturningclockwise.
15. Turnonthegassupplyshutoffvalveandtestforgasleaks.
16. Restorepowertotheboiler.
Nextyoumustfillintheinformationandaffixtheincludedfuelconversionlabelstotheboilerasindicatedafterthe
conversioniscompleted.
