5.
Flame Sensing Fault:
A) Flame Lost During Run: The gas control turns off pilot and main valves. The gas
control increments the recycle count, if the recycle count has not reached its limit
(4), another trial for ignition begins. If the recycle count has been reached, the gas
control LED flashes 6 times then 3 times with a 3 second pause. The gas control
waits 5 minutes before repeating the ignition sequence.
B)
Flame Sensed Out of Sequence: The gas control only looks for pilot flame when
the relay is energized. If flame is present when the pilot valve is not open, the gas
control proceeds to wait for flame loss and flashes 5 times with 3 second pause.
This continues until flame is lost. Once the flame signal is lost, the control flashes 6
times then 4 times with a 3 second pause. The control waits 5 minutes before
repeating the ignition sequence.
