Important
Only a licensed tradesperson can install, adjust, maintain and service this water heating system.
Any work carried out by a non-licensed tradesperson is illegal and will void any warranty.
Catch pan
It is important a suitably drained catch pan (or drain system) is fitted where damage could be
caused by discharge from the cylinder. This is a mandatory requirement of the installation. If
damage is caused by a leaking cylinder that has not been installed with a suitable drain system the
owner can seek compensation through the installer or consider claiming on insurance.
In the event of a power failure
The system will not operate without electricity. In the event of a power failure, when power is
restored the water flow may need to be stopped and restarted to get the system working again.
Frost protection
Frost protection
1
is fitted as standard on all Rinnai INFINITY models. Frost protection operates
automatically, as required, whenever the appliance is connected to the power supply.
If power has failed and there is risk of damage from frost, turn off the gas supply to the unit, and
open a tap slightly to allow flow through the unit. This may prevent damage from freezing. If the
system is not going to be used for an extended period and the power supply is disconnected,
turn off the water and gas supply and arrange for a plumber to drain all water from the system to
prevent frost damage.
Flue outlet discolouration
The colour of the flue outlet on an external Rinnai INFINITY may change over time due to
condensate in the exhaust gases. This is normal. The discolouration will not damage the unit, and
will not affect performance of the water heater.
Do not adjust the thermostat settings
The warranty is not valid unless the following settings remain:
• Rinnai INFINITY
75 °C
• Cylinder set temperature
65 °C
• Cylinder low limit temperature 60 °C

Frost protection turns on when the temperature inside the unit drops below 3.5 °C and switches off when the temperature reaches
7 °C. The heat inside the unit is provided by ceramic heating elements that stop the water within the pipework of the unit from freezing.
