Restart Features
All ES, EX, and C-Series models will attempt restart after a
power failure or flame failure to ensure heating is not
interrupted for extended periods of time.
• If there is a power failure while the appliance is operating,
the unit will attempt to restart automatically when the power
is restored.
• The timers will retain their settings after a power outage.
• After an outage, the clock will retain the time at that
moment until power resumes. Therefore, a short power
outage (a few minutes) will have virtually no effect on timer
operations whereas a longer outage will require the clock to
be reset. Dashes will initially display to indicate an outage
occurred.
