Cleaning the Ultraviolet Flame
Detector of the GasTrac
A dirty ultraviolet flame detector may fail to recognize burner ignition, which will
cause the GasTrac to alarm and shut down automatically.
To clean the ultraviolet flame detector:
1
Stop the GasTrac.
Press the red
“STOP” button, then press the rocker
switch to “OFF.”
2
Disconnect and lock out the main power.
3
Remove the flame detector.
Loosen the mounting nut
while holding the flame detector, then pull the detector
away from the viewing hole.
4
Clean the viewing hole lens.
Use a soft cloth or cotton
swab moistened with alcohol.
5
Replace the flame detector.
Align the detector over
the viewing hole, and thread the silver mounting nut
onto the coupling. Hand tighten first. Then using an
appropriately-sized wrench to tighten the nut an
additional quarter turn.
Replacement flame detectors
are available from Conair.
