Restart Function

If there is a power failure while the appliance is on, then the appliance will start automatically when the power is restored.

If the appliance fails to ignite, the appliance will attempt ignition after 1 hour. The “Ignition Failure” fault code, 11, will appear during that hour and disappears after a successful ignition. If ignition fails again, then the fault code will remain and another attempt to ignite will occur in 1 hour. The fault code is not stored in the fault code history.

If the flame is extinguished during forced combustion then the appliance will attempt ignition after 1 hour. The “Ignition Failure” fault code, 11, will appear during that hour and disappears after a successful ignition. Forced combustion takes place for about 15-18 seconds before ignition. After this time, the temperature control logic controls the combustion.

If the flame is extinguished (burner combustion failure) while the temperature control logic is operating the appliance, then the appliance will immediately attempt ignition. No fault code will appear.
