An Energy Cut Out (ECO) is incorporated in the sensor and control board which will shut off all gas supply to
the burner if the water heater temperature exceeds 207°F (97.2°C). Should the ECO function (open), the water
temperature should be reduced to approximately 120°F (49°C) and a qualified service agent must be called to
place the water heater in operation. The water heater must have the problem corrected by a qualified service
agent before putting the water heater back in operation. It is recommended that all service work be performed
by a qualified service agency.
