During a cold start of the appliance, the control will expect to sense a pilot flame before this timer times out. If on a cold start, a pilot flame is not sensed by the control when this timer expires, the control outputs will be turned OFF(heat will be turned off), and an alarm will sound. The default value for this timer is 60 seconds. The value range of this setting is 10 – 60

With the control display showing [MORE ], press product key 8. The display will show [FLAME xx], where xx is the current pilot flame sense timer value in seconds. Enter the new value using product keys 0-9. Press the program key to save this setting. The display will now show [MORE ]. Continue on to the other more service menu options above, or press the program key three times to return to normal operation(display shows either [READY], [ACT xxx’F], or [FILLING ]).

5.0 Control Alarm Displays:

This control continually monitors the basic overall functions of the appliance. If any faults are detected, the control will turn all outputs OFF, suspend any cooking functions that may be in progress and sound an alarm. One of several alarm messages detailed below will appear on the control display. If one if these alarms occur, turn off the control(see section 1.2). to reset the alarm.
