The Heat Exchanger
If the heat exchanger fails within Fifteen (15) years after the original installation and operation, Bosch Thermotechnology Corp. will furnish a replacement heat exchanger. However, if the water heater is used within an approved hot water recirculation and supplied with circulated water, this heat exchanger warranty is limited to three (3) years from date of original installation and operation. If the water heater is installed in other than a single family dwelling, this heat exchanger warranty is limited to two (2) years from date of original installation and operation.

2. to damage or abuse, accident, neglect or freezing and other acts of nature;
3. to damage resulting from operation with either the flame sensor rod or overheat sensor removed;
4. to failure of the heat exchanger resulting from the operation of the water heater in a corrosive atmosphere or at water temperatures exceeding the maximum rating, or if the water heater is not supplied with potable water;
5. to defects or damage cause by any attachment or modification, including any energy-saving device;
6. to damage resulting from scale deposits and/or highly mineralized / unsoftened water supply.
All Other Parts
If any other part fails within five (5) years after original installation and operation, Bosch Thermotechnology Corp. will furnish a replacement part free of charge.
