FEATURES
• Room Sealed: Air for combustion is taken fromthe outside and the flue products are exhausted
to the outside. This means heater operation has no effect on the composition and quality of air
in the room.
• Push Button Ignition: Only one touch of the STANDBY/ON switch is all that is required to
operate the heater.
• Lock: When the Lock function is activated all controls other than the STANDBY/ON switch will
be locked. Deactivating the lock releases the controls. If the lock is activated when the appliance
is in STANDBY, all functions will be locked.
• Memory: The heaters micro-computer records preset temperatures, timer programming, and
operational modes. Even in the event of a power failure, the need for reprogramming is
minimised.
• Dual Timer: The Dual Timer allows you to program the appliance to operate for two separate
periods each day. Once programmed the heater can then be controlled by selection of the Timer
1 and or Timer 2 functions.
The Dual Timer feature means that you can "Set and Forget" your heater. It will turn itself ON
or to STANDBY at the times you have programmed until you cancel the Timer program.
• Pre-Heat: This function automatically operates the appliance before the programmed ON time
of the Timer, in order to heat a room to the pre-set temperature by the programmed ON time.
• Remote Control: Full function cordless remote for the convenience of operating the heater
from a distance.
• Auto-Off Function: The Auto-Off function is an energy saving feature designed to control the
room temperature economically. If the room temperature continues to rise when the heater is
thermostatically turned down to its lowest setting the front burner will turn off leaving only the
pilot flame operating. When the room temperature requires further heating the heater will
automatically re-ignite to warm the room.

Rinnai 6 Operation Manual
BASIC HEATER OPERATION
GENERAL NOTES ABOUT IGNITION
This appliance has a sealed combustion chamber that requires purging before gas is allowed to flow
and the ignition sequence begins. As a result the combustion fan starts several seconds before there
are any signs of ignition. The normal ignition sequence is as follows:
OPERATION WITHOUT THE REMOTE CONTROL (AUTOMATIC MODE)
1. When the On/Off button is pressed the Operation Indicator LED
will glow red and Combustion fan will rotate to purge the system.
2. Pilot sparker operates.
3. As soon as a spark is sensed, gas will flow to the pilot.
4. When the pilot flame is established gas will flow to the front burners and then to the rear burners.
5. When all burners are established the heater will automatically modulate between burner settings
to achieve and maintain the default set temperature of 22°C.
When using the heater for the first time or after long periods of non use, ignition
may not occur the first time it is operated dueto air in the gas pipes. If ignition does
not occur within approximately 60 seconds the appliance will attempt to re-light,
however if ignition continues to fail the unit will cease operation automatically. Try
operating the heater again if this occurs.
The heater may make noises after ignition or extinction. This is due to expansion
and contraction of the internal components and is normal.
The heater will not ignite if the ON/OFF button is pressed straight after extinction.
After approximately 20 seconds has passed the unit will automatically go into
ignition mode.
The remote control stores the clock, timer and temperature settings for the heater. The heater can
be operated and stopped without the remote control by simply using the On/Off button on the top
panel of the heater. Operation in this manner is known as automatic mode. In automatic mode the
default set temperature is 22°C. For operation in other modes the remote control must be used.
OPERATION WITH THE REMOTE CONTROL
For the remote control functions to be available, the heater must be switched
between standby and off using the remote control.
The remote control emits an Infra Red (IR) signal and must be aimed at the
receiver unit located to the right of the warm air discharge louvre . The
normal operating range is approximately 5 metres, up to an angle of
approximately 40 degrees to the horizontal. This range may vary depending
on the position of the installation and the strength of the remote controller
batteries. The remote control transmits information to the heater whenever a
button is pressed except as follows:
1. When the remote control display is de-activated and any button is
pressed to restore the display
2. When the lock function is activated
When the timers are being set, timer information is transmitted only when the
‘Time Set’ button is pressed.
Signal transmissions are confirmed by a brief illumination of the Transmission Signal Indicator
on the Remote Display and at the heater the Remote Control Indicator located to the right of
the warm air discharge louvre will flash and a beep will sound to confirm that the settings have
been received.
When the remote control is not used for a period of approximately 5 seconds the
display will then default to stand-by mode, displaying only the time.
To re-activate the remote control press any button on the keypad. This returns the
display to the previous mode. No information is transmitted from the controller to
the heater when re-activating the display.

time. Then press the Time Set button once.
If you do not want to set the timers at this point then press the
Time Set button 4 more times until the display returns to
the time. If there is no button pressed for approximately 90
seconds then the screen will deactivate and any settings that
have not been transmitted will be lost.
Timer Setting
3. "Timer 1 Set ON" and "AM 06:00" will be displayed. Use the Up
and Down buttons to set the desired "AM" or "PM" "ON" time. Press
the Time Set button once.
4. "Timer 1 Set OFF" and "AM 09:00" will be displayed. Use the Up

be re-programmed.
PRE-HEAT
This function operates automatically in conjunction with the Timers. When a Timer is selected, the
heater may operate anywhere within an hour prior to the programmed ON Time.
This function is calledPre-heat as it ensures the room reaches
the desired temperature by the programmed ON time. This is
achieved by sensing the rooms temperature one hour prior to
start.
The difference in room and set temperatures at the time of
sensing the room temperature determines exactly how long
before the programmed ON time the micro-computer will ignite
the burner.

Rinnai 11 Operation Manual
CARE AND MAINTENANCE
CLEANING
Your heater needs very little maintenance, however the following information will help you keep it
looking good and working efficiently.
FILTERS
• Unplug electrical cord before cleaning.
• DO NOT USE SOLVENTS. All parts of the heater and remote control can be
cleaned using a soft, damp cloth and a mild detergent.
• DO NOT attempt to clean the heater while the appliance is hot or operating.
The filters for this appliance are located inside the Room Air Return
doors and consist of two metal mesh strips.
The build up of dust or other particles on these filter strips reduces
the air flow through to the heater which in turn reduces heater's
efficiency and can lead to the appliance shutting down.
Filter Care
Filters require cleaning regularly during the heating season to
prevent these unnecessary cut-outs.
To remove filter strips for cleaning:
A. Open both the Room Air Return doors, the doors have
spring loaded latches and are hinged to open towards the rear.
Pressing the front edge of these doors will unlock the spring
loaded latches and allow the doors to swing open.
B. Carefully slide filter strip upwards until the bottom tab clears the
lower retaining slot.
C. Slide the filter strip down and away from door to remove.
Cleaning filter strips:
D. Clean any dust and other debris from both faces of the filters
with either a vacuum cleaner, a soft dry cloth or a soft brush.
NEVER attempt to clean filters with water.
To re-insert filter strips:
E. Carefully slide the upper tab labelled “TOP” (no hole) back into
the upper retaining slot.
F. While holding the filter flush with the door lower the filter until
the lower tab has engaged the lower retaining slot.
G. Close both the Room Air Return doors so that the spring
loaded latches re-engage.
Heater shut down due to filter blockages
DO NOT wait for the Filter Blockage Indicator to come on before
cleaning filters.
DO NOT continue to use the heater once this Indicator is flashing.
When an obstructive build up is detected the Blockage Indicator LED which is located above the
Receiver Window will begin to flash RED to let you know that there is a problem.
Once the Indicator is flashing if no action is taken the heater will eventually shut down to avoid
overheating and a fault code of 14 will be displayed in the Error Display window.

Rinnai 12 Operation Manual
CARE AND MAINTENANCE
Returning the appliance to normal operation after a shut down
To restore to normal operation after a filter blockage shut down do
the following:
1. Press the On/Off button once to turn off the heater.
2. Remove obstruction (see “Filter Care” on page 11).
3. Press the On/Off button once to turn the heater back on.
4. Use the remote control to resume normal heater operation.
LOUVRES
It is important that the Louvres of the Warm Air Discharge be
kept clear of any obstructions as this will cause your heater to
operate less efficiently.
When an obstruction is detected the Blockage Indicator LED which is located above the Receiver
Window will illuminate RED and the combustion state reduces to front burner, low operation only.
To restore normal operation remove the obstruction and use the remote control to resume normal
heater operation
GENERAL HEATER CHARACTERISTICS
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 room fan air is started automatically after a short delay. This is to allow the heat exchanger to
warm up, helping to avoid cold draughts.
Smoke or strange smells are produced on
the first up operation after installation. This is caused by grease, oil or dust on the heat exchanger. This will stop 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.
During combustion:
Clunking noise when the thermostat
operates This is the sound of the solenoid gas valves opening and closing to regulate the gas flow.
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.
Other points:
Steam is discharged from the flue terminal. High efficiency appliances tend to discharge
water vapour on cold days. This is normal.
Heater does not start when the STANDBY
/ ON button is pushed, thermostat is on
High (H).
Check that the appliance On / Off button is ON.
Check Timer(s). Timer(s) programmes must be
turned off or overridden for manual operation.
Timer(s):
Timer(s) do not operate at set time. Timer(s) may either be inactivated or incorrectly
programmed. Please confirm Timer(s) are set
correctly. See page 9 for correct Timer(s)
operation.
Timer operates for a short period and then
cuts out. Room temperature may be higher than the set temperature. Increase set temperature if desired.
Cancel the Auto Off function.
