Proceedtoputtheboilerintooperationasfollows:
5.Activatethechimneysweepfunctionbypressingandholdingtheeasymenuandmenubuttons(Fig.49a)whilstinthenormaloperationscreenuntilchimneysweep
functionoptionappears.PresstheSelectorButtontoswitchthechimneysweepfunctionon.
6.TheTHINKControllerwillshowChimneySweepFunctionon.ChimneySweepfunctionBurnerOutputAdjustappears.
PresstheSelectorButton.'Engineburnermin'willflash.
Usethewheeltoscrollthroughthesixoptions
a)Engineburnerminimum
b)Engineburnermaximum
c)Supplementaryburnerminimum
d)Supplementaryburnermaximum
e)EngineandSupplementaryburnersminimum
f)EngineandSupplementaryburnersmaximum
7.Choosethemaximumoperationf)andokyourchoice.Nomatterwhatthepreviousstateis,theburnerswillrestartbeforeachievingthedesiredrate.
Assoonasbothburnersarelitasshownbytheflamenumbers .
8.Withtheboileroperatinginthemaximumrateconditioncheckthattheoperational(working)gaspressureattheinletgaspressuretestpoint(Fig.50)isinaccordancewith
B.S.6798&B.S.6891.
9.Ensurethatthisinletpressurecanbeobtainedwithallothergasappliancesinthepropertyworking.

c)Thepowergeneratedreaches1kWtheengineburnerwillmodulatedown.
Forthisreasonthemeasurementneedstobecarriedoutonacoldsystemtobesureofobtaininganaccurateresult.

NOTE:Theboilersetflowtemperatureissetto90°toavoidinterruptionoftheratemeasurement.
11.Thechimneysweepfunctioncanbedeactivatedinthesamemannerasitisactivated.Itwilldeactivateautomaticallyafter20minutes,orintheeventofanfault.
