THERMOSTATS
ACCModels.Twoaccessoryoptionsareavailable:
•Thehand-heldIRRCModel300non-programmableremotethermostat.
•Thewall-mountedprogrammablethermostat.
Instructionsforinstallingbothoptionsaresuppliedwiththem.
ECSModels.Anoptionalbatterypoweredwall-mountedprogrammablethermostatisavailable.
GASPRESSUREADJUSTMENT.Allpressureadjustmentsmustbemadewhiletheheateris
operatingonthe‘HIGH’setting.
ACCNGandACCLP.Thesehaveapressureregulatorinsidethecontrolvalve.Therearetwotestpoints
sidebysideontopofthecontrolvalve–theoutletpressuretestpointistheoneclosertotheflamesize
controlknob.Ifadjustmentisnecessary,uncouplethecontrolrodfromthetopoftheflamesizecontrol
knob,extractthescrewfromdownthecentreofthisknobandpulltheknoboffvertically.Thepressureis
thensetbyrotatingtheknurledplasticwheelexposedbyremovingtheknob.Oncethepressureiscorrect
(0.95kPaforNGor2.5kPaforLP),caremustbetakennottoturntheplasticwheelastheknobisre-
fittedinitsmaximumanti-clockwiseposition.Thispositionissetwhentheskirtoftheknobcontactingthe
adjacent metal up-stand. Rotate the knob clockwise and then fully anti-clockwise while observing the
pressuretoverifythatitiscorrectbeforereplacingtheretainingscrewandre-couplingthecontrolrod.
ECSNGandECSLP.Thesealsohaveapressureregulatorinthecontrolvalve.Theoutletpressuretest
pointisonthetopofthecontrolvalveandistheoneremotefromthegasinletconnection.Therearetwo
pressuresettingstoadjust,highandlow.Accesstotheadjustersisgainedbyfirstremovingtheheatshield
abovethevalveandthen removingtheprotectivetransparent cap at the very top of the control valve
modulatingcoil.Thiswill expose the central screw(low pressureadjuster) anda10mm hexagonalnut
surrounding it (high pressure adjuster). Note that the modulating coil may be rotated through 90° if
necessarytoprovideeasieraccessforpressureadjustments.Beforeadjustingthehighpressure,the fire
mustbealightandburningatthe‘HIGH’setting.(Holddownthe+endofthetoprockerswitchonthe
handpiecefor30secondstoensurethis).
Setthehighpressurefirst.NGhighpressureshouldbe0.95kPaandLPhighpressureshouldbe2.3kPa.
Adjust,ifnecessary,byrotatingthe10mmnut,screwingdowntoincreasethepressureanduptodecrease
it.
Beforesettingthelowpressure,removeoneofthebluewiresconnectedtothetopofthemodulatingcoil.
Thereis noneedtoalterthehandpiececontrolsetting.Adjustthelow pressureby rotating the central
Phillipsheadscrew,takingcarenottoshiftthepositionof thealreadyadjusted10mmhex.nut.Screw
downtoincreasethepressure.Thecorrectlowpressuresare1.0kPaforLPand0.40kPaforNG.
Replacetheprotectivecapontopoftheadjusters,re-fitthebluewiretothemodulatingcoil,rotatethe
assemblyabovethecoiltoitsoriginalpositionandre-fittheheatshieldabovethevalve.
FAN
ACCMODELS. Thesehave a Thermodischeat operatedswitch incorporated in the fan wiring circuit to

ECSMODELS.ThesehaveaThermodiscalso(seeaboveparagraph).Oncethefireboxhasheatedup,check
thefanoperationbypressingthelowerrockerswitchonthehandpiece.Pressingthe+endrepeatedlywill
increasethespeedthroughallfourfanspeedsettings(threespeedsandoff),whilepressingthe–endwill
