All terms of the warranty are effective from the date of installation of the Rinnai Demand Duo 

system. Rinnai New Zealand Limited (Rinnai) reserves the right to verify this date. 

Domestic vs. Commercial Application

The reason for distinguishing between a domestic and commercial application is because the 

expected life of a system is directly related to the hours of use.

A domestic application is defined as an installation that serves a single residential dwelling 

which is not used for commercial purposes, such as a hair salon, catering kitchen, motel or 

communal care facility.

All other installations are defined as a commercial application.

General Warranty Terms

Rinnai reserves the right to make modifications and change specifications and its parts without 

notice.

For the purposes of the Consumer Guarantees Act 1993, Rinnai only guarantees the availability 

of repair facilities and spare parts for the express warranty periods recorded in the Rinnai 

Warranty Summary Table.

If the Rinnai Demand Duo system is being acquired for personal, domestic or household 

use, this warranty does not limit any consumer rights or guarantees that may apply under 

the Consumer Guarantees Act 1993. If the product is being acquired for the purposes of a 

business, the provisions of the Consumer Guarantees Act 1993 do not apply and no other 

warranties (either express or implied by law) apart from those stated in this warranty apply.
