Rinnai Australia 2 Ultima II Operation Manual
FEATURES
• The Rinnai Ultima II is one of the most efficient gas space heaters available in Australia.
This has been achieved by combining good design with the latest technology, making the heater
both highly efficient and easy to use.
• Downflow Convection operation and large capacity fan ensures effective heating to all parts of the
room and reduces stratification.
• 30 MJ/h input, large enough to suit most domestic applications.
• Ignition is fully automatic and the burner is continuously monitored by an electronic flame failure
system. If the flame is extinguished during operation, the gas supply is shut off immediately.
• Electronic temperature controls ensure that the room stays at the temperature you have selected.
• Electronic dual ON and OFF timers.
• Filters to protect the burner from dust and lint.
• Automatic fan switch to turn the fan on and off and match the fan speed to the heat input at all
times, increasing efficiency and comfort.
• Overheat switches avoid hazards should the appliance overheat.

HOW TO OPERATE THE HEATER
TO TURN THE HEATER ON
Before you begin ensure that the Gas and Power
have been connected and turned on.
The combustion chamber of this appliance r equires
purging before gas flows and the burner sequence
begins. As a result the combustion fan starts several
seconds before there are any signs of ignition.
Press the STANDBY/ON button once to begin the ignition sequence. The On/Combustio n indicator
will glow green and the combustion fan will cycle to purge the combustion chamber. Once purged
burner ignition will take 5 ~ 10 seconds. The ON/Combustion indicator will change to Red (steady)
after ignition has been achieved.
After ignition the appliance will begin to operate in the following factory preset manner:
• The TIME / will display - - : - -, to set the time see page 8.
• The temperature displays TEMP and will show the current room temperature CURR . The
default set temperature SET will be 22°C. See below on how to adjust set temperature.
• The default operating mode is GAS , see page 7 for modes of operation.
TO ADJUST SET TEMPERATURE
The set temperature may be raised or lowered by use of the Up and Down buttons . The selected
temperature will be displayed under the SET icon of the TEMP display .
The following set temperatures can be selected.
• 'L' for continuous combustion on the lowest burner setting, without thermostatic control.
• Thermostatic control between 16°C to 30°C in 1°C steps
• 'H' for continuous combustion on the highest burner setting, without thermostatic control.
The current room temperature will display temperatures between 1°C to 30°C.
Once the temperature is set it will be stored in the memory of the microcomputer. If the temperature
is not adjusted further it will be the default setting when the appliance is next used.
TO TURN THE HEATER OFF
To turn the heater off while it is in operation press the STANDBY/ON button located on the control
panel. The On/Combustion indicator w ill go out and the digital display will revert to the CLOCK
display.
To save energy, during standby the digital display will de-activate (go blank) after 10
seconds. Pressing the STANDBY/ON button overrides this feature and will initiate
the ignition sequence, pressing any other button once re-activat es the digital display.
When using the appliance for the first time or after long periods of non use, ignition
may not occur the first time it is operated as there may be air within the pipes. If
ignition does not occur after approximately 30 seconds the heater will cease oper ation
automatically. If this occurs press the STANDBY/ON button twice to restart.
This heater may make noises after ignition/extinction. This is due to expansion and
contraction of the heater components and is normal.
The heater will not immediately ignite if the STANDBY/ON button is pressed
straight after extinction. After approximately 20 seconds has passed, the heater will
automatically go into ignition mode.
Rooms may not arrive at the SET temperature due to the size and construction of the
room, location of the appliance or external temperatures.
If the appliance does not ignite then the actual room temperature may already be
higher than the pre-set temperature.
After the On/Combustion indicator has gone out, the appliance fan will continue to
cycle for several minutes. This is to lower the temperature within the appliance and is
normal. DO NOT disconnect the power during this time.

HOW TO OPERATE THE HEATER
MODES TO DELIVER COMFORT AND ECONOMY
Your appliance has several MODE settings to choose from. The factory default mode is GAS. If the
mode is not adjusted this will be the default setting the next time the appliance is used.
As a room is warmed, the walls and ceilings are also warmed, making one feel a little warmer than
when the ceilings and walls were cold, even though the room temperature is the same. The economy
mode prevents discomfort from overheating and saves energy.
GAS MODE
Gas combustion in this mode is continuous and will adjust automatically to maintain the set
temperature. This is the factory default mode for the appliance.
GAS / ECON MODE (ECONOMY MODE)
In this mode, once the set temperature has been maintained for a period of 30 minutes, the comfort
control system will progressively lower the set temperature by 2°C over a period of 60 minutes. When
GAS / ECON mode is selected, gas combustion is continuous and will adjust automatically to maintain
the set temperature minus 2°C.
GAS / ECON / AUTO OFF MODE
In this mode, once the set temperature has been maintained for a period of 30 minutes, the comfort
control system will progressively lower the set temperature by 2°C over a period of 60 minutes. When
GAS / ECON / AUTO OFF mode is selected, gas combustion will start and stop automatically to
maintain the set temperature minus 2°C.
SELECTING MODES
The current operation mode is displayed on the digital display and the SET button is used to
select which mode the heater will use during operation.
The select a different mode press the SET button whilst the appliance is in operation, this will cycle
the heater through the available modes as follows:
During operation in GAS / ECON mode the current room
temperature (CURR ) may be lower than the set temperature
(SET ), however this is normal.
During operation in GAS / ECON / AUTO OFF mode the current room
temperature (CURR ) may be lower than the set temperature
(SET ), however this is normal.
The MODE selected will be stored in the memory of the microcomputer. if the MODE
is not changed further it will be available as the initial setting when the appliance is
next used.
