Specifications

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.

• Should a high gust of wind, gas outage, etc. occur that affects the flame characteristic, the

unit will automatically shut down, purge the combustion chamber, and re-ignite

• If the unit cannot ignite or maintain flame for 15 seconds after ignition, code 11 will flash

and the unit will try to ignite again in one hour

• This code will not be stored in the fault code history

• If at some point after 15 seconds of established flame the flame fails, the unit will

immediately attempt to relight with no code flashing

• If the unit cannot relight after this flame failure, code 11 will flash and the unit will try to ignite again

in one hour

• If the unit continually or intermittently fails to ignite, a qualified service technician may be needed to

determine the cause

• Each manual has a section named ―Restart Function‖ that explains this procedure

• Flame failure fault codes (code 12’s) are no longer needed due to this enhancement
