REGULATORY INFORMATION
WARNING ABOUT HOT WATER

Rinnai Australia 2 Operation Manual
FEATURES AND BENEFITS
Congratulations on purchasing the Rinnai Instantaneous water heating system.
•The appliance NEVER RUNS OUT of hot water. Whilst water and gas supplies are connected and available and
battery power is available, hot water is delivered whenever hot water taps are open.
•The appliance is compact, saving both wall and floor space.
•The burner lights automatically when the hot water tap is opened, and goes out when the tap is closed.
IGNITION IS ELECTRONIC rather than by pilot light for optimum reliability and minimum running costs. When
the hot water tap is closed no gas is used.
•The appliance has a very high gas combustion efficiency minimising gas consumption and operating cost.
•Operating noise level is very low.
Unlike most other instantaneous water heaters, this model is fitted with a battery powered electronic ignition and
microprocessor control module offering unique benefits as follows:
•Electronic ignition rather than ignition by pilot light ensures optimum reliability and minimum running costs as no
gas is used when the hot water tap is closed.
•The water temperature and gas flow are microprocessor controlled offering superior performance.
•Battery power ensures optimum reliability and eliminates the need for a mains power supply and associated
costs.
Unlike most other instantaneous water heaters, this appliance also has a modern state of the art flue design for
reliable operation even under high wind conditions.

Rinnai Australia 3 Operation Manual
IMPORTANT INFORMATION
The range of Rinnai Instantaneous water heaters referred to in this manual are incompatible with
solar water heating systems. A dedicated range of solar compatible continuous flow water
heaters is available from Rinnai.
Always check water temperature carefully before use. Refer
to the WARNING ABOUT HOT WATER in this manual for
important safety information.
At low water flows, the hot water unit may extinguish without
warning. Opening the tap further will restart the appliance.
Do Not touch the unit cover or the flue outlet.
Do Not insert objects into the flue outlet.
On colder days steam may discharged from the flue outlet.
This condition is normal for high efficiency appliances and
does not indicate a fault.
Keep flammable materials, spray cans, fuel containers, pool
chemicals, trees, shrubs, etc. well clear of the flue outlet.
Do Not spray water directly into the flue terminal.
NOTE

Rinnai Australia 4 Operation Manual
OPERATION
The opening of any hot water tap will automatically start the appliance.
Once water is flowing through the appliance the burnerwill beignited by electronic ignition via the electronic ignition
and control module.
When the hot water tap is closed and water flow through the appliance has stopped the burner flame will extinguish.
Battery for electronic ignition and control module
A long life 1.5 Volt "D" size battery is supplied with the
appliance and should have been fitted by your installer.
If the battery runs flat, replace it with a new 1.5 Volt "D"
size battery. Long life batteries are recommended. The
battery compartment is located on the left hand side at
the bottom of the appliance. Approximate battery life is 6
months. Actual battery life may be different depending
on individual hot water usage patterns.
1. Locate the battery compartment and open the
hinged lid (opens towards the rear of appliance).
2. Remove the expired battery and replace it with a
new battery ensuring that the correct polarity is
observed, as is shown on the inside of the battery
compartment lid.
3. Close the the battery compartment lid.
DELIVERY TEMPERATURE
The delivery temperature set point programmed into the electronic ignition and control module is 60°C.
The actual delivery temperature may be lower depending on the prevailing operating conditions, for example, low
incoming cold water temperatures and high water flow rates.
Hot Water can cause severe scalds.
Those most at risk are children disabled, elderly and the infirm.

OPERATION
WATER FLOW AND TEMPERATURE ADJUSTMENT
Water fixtures with a rated water flow rate of 7.5 litres per minute or higher are recommended.
A water flow adjustment lever is fitted to adjust the maximum water flow from the appliance. Such adjustment may
be useful to compensate for seasonal variations in the temperature of the cold water supply.
• Turning the water flow adjustment lever towards the left (Clockwise) will decrease the water flow and increase the
hot water temperature. This setting is recommended during winter.
• Turning the water flow adjustment lever towards the right (Anti-clockwise) will increase the water flow and
decrease the hot water temperature. This setting is recommended during summer.
• If the heated water temperature delivered from an outlet is not hot enough it can normally be increased to the
desired temperature by closing the tap a little as this will reduce the water flow rate.
• The appliance has a minimum water flow rate that is required for operation. If the water heater does not activate
when opening a tap, the flow rate may be too low. Open the tap a little more to increase the water flow rate.
Freezing Weather
If freezing conditions are expected (drop below 0°C), turn off water and gas and drain all water from the appliance
to prevent damage by expansion of freezing water.
For appliances installed in locations where the temperature falls below 0°C for short periods, the installation of an
Anti Freezing Relief Valve will minimise the possibility of damage to the appliance.
This water heater MUST NOT be installed in areas where the temperature remains below 0°C for
extended periods.
