14 Limited Warranty

General

Aquastar water heaters are warranted by the

Manufacturer (BOSCH) through Bosch Thermotechnology Corp..

Bosch thermotechnology corporation will furnish a replacement heat exchanger and will furnish a replacement of any other part which fails in normal use and service within the applicable periods specified below, in accordance with the terms of this warranty. The Bosch Thermotechnology Corp. replacement will be warranted for the unexpired portion of the original warranty. This warranty will be valid only for water heaters in possession of the original purchaser as recorded on the warranty card.

The Heat Exchanger

If the heat exchanger fails within twelve (12) 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.

Exceptions

This warranty will not apply:

1. to defects or malfunctions resulting from failure to properly install, operate or maintain the unit in accordance with the printed instructions provided;

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.

Service Labor Costs

This warranty does not cover any labor costs associated with service, removal or re-installation of part(s). All such costs must be borne by the Purchaser. Additionally, this warranty does not cover any labor costs associated with service, removal, installation or re-installation of the original water heater or a replaced water heater.

NOTE: the water heater must be free of

idamaging scale deposits and not subject to gas pressures greater than those shown on the rating plate, which must not be altered, defaced or removed.
