Q385A
APPLICATION
Q334A and Q385A non primary aerated target type pilot
burners provide main burner ignition for gas appliances using
manufactured, natural or LP gas.
Q334A and Q385 pilot burners are used in conjunction with a
Honeywell thermocouple which has to prove the presence of
pilot flame before main gas is admitted into the appliance.

INSTALLATION
IMPORTANT
Installer must be a trained, experienced service man.
Turn off gas supply before starting installation.
An important requirement for the Q334A and Q385A
pilot burner is that it must be installed carefully.
Consult Honeywell application engineers when
considering using these devices.
Locating pilot burner
· Position for easy access and observation.
· Position so that pilot flame will not touch adjacent parts or
main burner flames.
· Position so that pilot flame will ignite main burner when
pilot gas pressure just exceeds safety shut--off pressure.
· Ensure that pilot flame has an ample supply of dust free
air.
· Do not expose to draughts which will extinguish pilot flame.
· Pilot burner should not extinguish when main burner is
switched ON and OFF.
· Pilot burner shall be mounted in a preferably upright
position.
Mounting pilot burner
Fix pilot burner to main burner at selected location. Mounting
surfaces other than main burner should be avoided as much
as possible since they may shift, bend or deform due to close
proximity of main burner.
