REMOTE CONTROL OPERATION
BATTERIES AND ACTIVATING THE REMOTE CONTROL
• 2 x Button Batteries are supplied with the remote control.
• Remove the plastic tab to activate.
• This remote control uses 2 x Lithium CR2450 or equivalent batteries.
• The appliance will flash and emit 'Beeps' to confirm the setting has been received from the remote control unit;
this indicates your remote control is now working.
BUTTON FUNCTIONS, DISPLAY & OPERATION
This remote control, selects flame height and fan speed
in five levels.
The STANDBY / ON button switches the heater between
the STANDBY and ON modes.
Flame height may only be adjusted after at least 30
seconds of operation.
The UP / DOWN buttons control the height of the flame
and heat output.
The relationship between flame height and fan speed is
factory preset and cannot be adjusted, there are five flame /
fan settings as listed below.
The remote control temperature sensor (located base of the
controller) reads the temperature of where control is
currently located, this temperature reading is refreshed once
a minute.
For the remote control to be able to function, the appliance ON/OFF button must be in the "ON"
position. Using the remote control to turn off the heater will place the heater into STANDBY mode,
when in this mode the Red Power Indicator will be on. This is normal.
FlameHeight 12345
Fan Speed (2 speed only) Low Low Low High High
On initial start-up the appliance default flame
height setting is setting 5 - High. Use the UP /
DOWN buttons to control the height of the
flame / heat output.
The degrees Celsius room temperature display has a motion activated back light which will
remain illuminated for approximately 5 seconds after a movement is sensed or when a button is
pressed. Frequent illumination of the back light greatly reduces the remote controls operational
battery life, ensure that unnecessary illumination of the display is avoided.
IMPORTANT
a
b
Dispose of used button batteries immediately and safely. Flat batteries can still be dangerous and may be a choking hazard.
Inform others about the risk associated with button batteries and how to keep their children safe.
Remove the batteries if the remote is not going to be use for prolonged periods. This will help prevent damage from leaking
batteries. If leakage has occurred and corrosion is evident the remote will need to be replaced.
Leaking chemicals are toxic and MUST NOT be touched or ingested.
NEVER mix old and new batteries.
DO NOT immerse the remote control in any liquid, this will damage the remote control, rendering it inoperable and voiding
its warranty.
WARNING KEEP BATTERIES OUT OF REACH OF CHILDREN.
Swallowing may lead to serious injury in as little as 2 hours or death, due to chemical burns
and potential perforation of the oesophagus.

CARE AND MAINTENANCE
Your heater needs very little maintenance, but the following information will help you to keep it looking good and
working efficiently.
SERVICE
Rinnai recommend that this appliance and installation be inspected and serviced every 2 years or more frequently.
If the power supply cord or any other component of the heater are damaged, they must be replaced by Rinnai or
a suitably qualified person.
Any service or repair work should only be carried out only by an authorised person. Rinnai has service and spare
parts departments nationally. See back cover for contact details.
TROUBLE SHOOTING
General Operation Characteristics
DO NOT attempt to clean the heater while the appliance is hot or operating.
All parts of the heater can be cleaned using a soft, damp cloth.
DO NOT use solvents or abrasives to clean any parts.
DO NOT spray aerosols in the vicinity of the heater whilst in operation.
DO NOT place articles on or against this heater.
DO NOT use or store flammable materials in or near this appliance.
Service calls for general cleaning, maintenance and wear and tear are not necessarily covered
under the warranty. Service calls of this nature may be chargeable.
Faults caused by insufficient gas supply, gas quality, installation errors or operation errors are not
covered by the Rinnai warranty. Refer to separate Warranty Booklet for details or go online at
www.rinnai.com.au//support-resources/warranty-registration/
Before asking for a service call please check the following table as these characteristics are part
of the normal operation of the appliance and do not indicate a fault.
CHARACTERISTIC EXPLANATION
At ignition:
Warm air does not start when the burner
lights. The fan is started automatically after a short delay. This is to allow the heat exchanger to warm up, helping to avoid cold
draughts.
This is normal operation.
Smoke or strange smells are produced on
the first start up after installation. This is caused by grease, oil or dust on the heat exchanger.
This is to be expected and will cease after a short time.
Sharp clicking noises at ignition, or when
the unit thermostat modulates to a lower
or higher setting, or shuts down.
This is simply expansion and contraction noise from the heat
exchanger.
This is a normal operation sound.
During combustion:
Dull clunking noise when the thermostat
operates. This is the sound of the solenoid gas valves opening and closing to regulate the gas flow.
These are normal operation noises.
When the appliance is turned off:
Convection fan continues to run after
turning ‘OFF’. This is to remove residual heat from the heat exchanger and stops once the appliance cools sufficiently.
