condition if the error is such that it can return to normal operation once the condition relieves itself (overheat conditions, NTC open or shorts,
etc.). The water heater shall enter a hard lockout if the condition indicates something more serious (ame, ignition, condensate line, etc.) To
clear a hard lockout Error Code, press the Power button. See Figure 66 B.
