For reliable operation Rinnai continuous flow water heaters in domestic applications should
be serviced every two years (including inspection of the flue system if installed). A service
record has been provided at the back of this manual. For commercial applications Rinnai has a
recommended Commercial Maintenance and Servicing Schedule. This is available on request or
via our website - www.rinnai.co.nz.

Rinnai.

Rinnai New Zealand Ltd
There is a recommended system layout for Rinnai continuous flow water
heaters used in solar installations. It is important your installer configures
your solar system correctly as water heaters in solar installations produce
higher than normal temperatures.
Rinnai water controllers cannot be used with Rinnai continuous flow
water heaters in solar installations as the hot water does not always pass
through the continuous flow unit.
The Rinnai continuous flow water heaters are factory preset to a
temperature limit of 55 °C (excluding one commercial model - Infinity
HD200 external).
Temperature controllers are available to allow precise digital temperature
control—a great safety feature if you have young children. Controllers can
be fitted at any time (except in solar installations) after installation of the
hot water unit.
The flow will vary slightly depending on the incoming water temperature
and temperature selected. For example the water flow will be higher at
43 °C than at 55 °C.
There is also a minimum flow rate required for the continuous flow unit
to start. So if a hot water tap is only opened a fraction there may not be
enough flow to start the unit.
