APPLICATION
Q334Aand Q385Anon primaryaerated target type pilot
burnersprovide main burnerignition forgasappliancesusing
manufactured,naturalorLPgas.
Q334Aand Q385 pilotburnersare used inconjunction with a
Honeywell thermocouplewhich hasto provethe presence of
pilot flame beforemain gasisadmitted intothe appliance.

INSTALLATION
IMPORTANT
Installer mustbeatrained,experienced serviceman.
Turn off gas supplybeforestarting installation.
Animportantrequirement forthe Q334Aand Q385A
pilotburneristhatitmustbe installed carefully.
ConsultHoneywell application engineerswhen
considering using these devices.
Locating pilotburner
·Position foreasy access and observation.
·Position sothatpilot flamewill not touch adjacentpartsor
main burnerflames.
·Position sothatpilot flamewill ignitemain burnerwhen
pilotgaspressurejustexceeds safety shut--off pressure.
·Ensurethatpilot flame hasan amplesupplyofdust free
air.
·Do notexposeto draughtswhichwill extinguish pilot flame.
·Pilotburnershould notextinguishwhen main burneris
switched ONand OFF.
·Pilotburnershall be mounted inapreferablyupright
position.
Mounting pilotburner
Fixpilotburnertomain burneratselected location.Mounting
surfacesotherthan main burnershould be avoided asmuch
aspossiblesincetheymay shift, bend ordeform due toclose
proximityofmain burner.

Mounting ofignition electrode(see fig.1.)
·Placetip ofignition electrode between clip and bracket.
·Pushignition electrode upwards.
·Position electrode tipinthe holeonthe top of the bracket.
·Pushignition electrode furtherupwardsuntil the thickning
passesthe hookof the bracket.
Remounting ofignition electrode(see fig.1.)
·Pushmetalclipsidewards.
·Pull ignition electrode to disengage.
Fig.1.Mounting ofignition electrode
Pilotgas connection (see fig.2.)
·Square off end of tubing,clean,remove burrsand form it.
·With orifice assemblyand compression fitting in position,
insert tubing intotargetspud until itbottomsand turn
compression fitting fingertight.
·Holdtubing to prevent turning and tighten compression
fitting withawrench about twoturnsbeyond fingertight for
6mm tubing and about3/4turn beyond fingertight for4
mm tubing tomakeapressuretightjoint.
CAUTION
Do notbend tubing nearfitting aftertightening asthis
mayresultin gasleakage atconnection.
·Connectotherend of tubing to pilotgas supplyorgas
controlaccording the manufacturer’sinstructions.

·Beforelighting pilot flame, turnthermostat tothe lowest
setting.
·Shutoff gas supplytothe main and pilotburner.
CAUTION
Wait5minutesto allowcompleteventing ofany
unburned gas.
RememberLPgasisheavierthan airand will notvent
upwards.
·Turn on gas supplyand lightpilot flame according tothe
appliancemanufacturer’sinstruction.
·Pilot flameshould burnwithasteadyblue flame.
