Appliance control with automatic damper detection

Image Number 3 for United States Patent #8074892.

Methods and systems for operating a fuel fired appliance that may include an optional hardware component such as a damper are disclosed. In some cases, the presence of the optional hardware component is detected, and it is determined whether the optional hardware component is required for future operation of the fuel fired appliance. The fuel fired appliance may be operated normally if the optional hardware component is present and required, or, in some cases, if the optional hardware component is determined to be not required. If the optional hardware component is absent but required, normal operation of the fuel fired appliance may be stopped.
