COMPANY’S RESPONSIBILITY

The company’s responsibility is to repair or replace, at our option, with the prevailing compa-
rable Bock model, any part of the equipment, including the tank, sold by the company which
proves to be defective in material or workmanship during the warranty period, when installed
in accordance with applicable codes and ordinances, and operated and maintained in accor-
dance with our instructions, subject to the conditions and exceptions indicated below. Our lia-
bility, in the event of leakage or other malfunction, is strictly limited to repair or replacement
of the defective heater or part, as provided herein. We are not responsible hereunder for inci-
dental property damage or personal injury, consequential costs or damage. Equipment that is
repaired or replaced will carry the unexpired portion of the original equipment warranty.

At the company’s request, the owner is to return to the factory at Madison, WI, any part, in-
cluding the tank, defective in material or workmanship, and pay all transportation charges for
such return parts and for replacement parts sent from the factory to the owner. The owner will
pay all labor charges for the removal and installation of such parts, including the tank. Any
replacement water heater furnished under this warranty shall remain in warranty only for the
unexpired portion of the original warranty. The owner will have annual inspections of the
