FEATURES OF YOUR 1004T
Push Button Ignition: Only one touch of the ON/OFF button is required to operate the heater.
7 Step Automatic Heat Control with electronic thermostat. The fan is also controlled by the
thermostat.
Economy Mode: An energy saving feature that reduces the room temperature by 3˚C over a 90
minute period.
Lockable Control Panel Lid: The 1004T has a lockable Control Panel Lid which is ideal for
commercial use. This feature is great for applications where safety is paramount or when the unit is
required to be set once and left alone. Two keys are also supplied with the unit.
Function Lock: Prevents children from altering heater settings whilst running, or from activating the
heater when turned off. This feature is utilised if the Control Panel Lid is unlocked.
Heater Filter Indicator: When the heater filter becomes covered with dust and the temperature inside
the appliance rises, the heater filter indicator will flash indicating that cleaning is necessary.
The integral humidifier tray can be filled with water as required to raise the humidity level in the room.
Room Sealed: Air for combustion is taken from the outside and the flue product is exhausted outside,
keeping the room air clean.

HOW TO OPERATE THE HEATER
■Turning ON
●Press the ON/OFF button
・The ON indicator will illuminate green.
・The combustion fan will rotate.
・Ignition will take 5〜10 seconds and the
ON/Combustion indicator will change from
green to red to let you know that the
burner has ignited.
Note:
・When using the unit for the first time or after long periods of disuse, ignition may not occur the first time
it is operated as there may be air in the gas pipes. If ignition does not occur after approximately 30
seconds the unit will cease operation automatically.
Try operating the unit again if this occurs.
・The unit may make noises after ignition/extinction. This is the inside of the unit expanding and
contracting 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 back into ignition mode.
■Turning OFF
●Press the ON/OFF button
・The ON/Combustion indicator will go out.
・After the indicator has gone out, the
convection fan will continue to rotate for
several minutes, then stop. This is to
lower the temperature within the unit. Do
not pull out the power cord during this
time.
When the Function Lock is set, the Function Lock indicator will continue to illuminate even when the unit
is OFF and the Function Lock will not be cancelled.

CAUTION !
・Do not pull out the power cord or disconnect the power during combustion to cause extinction, or
straight after extinction, as this may cause damage to the unit.

ECONOMY MODE
ADJUSTING THE TEMPERATURE
Displaying, setting and adjusting the room temperature can
only be done when the heater is operating.
・When the unit is first operated, the room temperature is
set at 22˚C.
・Set the desired room temperature with the up and
down buttons while looking at the display section.
・The “Set Temp”can be set to “L”or between “12”〜
“26”, or “H”(continuous combustion on High).
・The “Room Temp”will display “L”(when lower than
1˚C), “1”〜“30”(at intervals of 1˚C), or “H”(when
higher than 30˚C).
・Once a temperature is set, it will be stored in the
microcomputers memory.
Note:
・Rooms may not arrive at the set temperature due to the
construction of the room, the location of the unit, or
external temperatures.

FunctionLock

The Economy Mode, when selected, has the ability to reduce gas consumption and ultimately save energy.
Once a room has reached the desired temperature, the unit will automatically begin reducing the set
temperature gradually. This reduction is normally not noticeable, however, it is purely your choice whether to
select this mode or not.
How it works
・After a room reaches the set temperature, the set room temperature will decrease 3 times automatically,
each time, dropping by a maximum of 1˚C in 30 minute blocks. From the second time onwards, the comfort
control will automatically operate. (The comfort control alters combustion and fan speed more frequently to
counteract the feeling of cold air.)
・The Economy indicator will illuminate to let you know that the Economy Function is selected.
・The Economy function will not operate when the set room temperature is less than 16˚C or above 26˚C.
・When the Economy function is operating, the current displayed room temperature may be lower than the
set room temperature, however, this is normal.

FUNCTION LOCK
1
The Function Lock can be operated either when the
heater is running, or in the “stand by”mode, by
pressing the up and down buttons simultaneously.
The Function Lock is activated and the Function Lock
indicator will glow.
2
To de-activate the Function Lock, simply press both
arrow buttons simultaneously for 2 seconds and the
Function Lock indicator will go out. The lock can be
de-activated at any time in this way.
The Function Lock will help to prevent accidental operation as well as small children from altering the
heater settings.
When the Function Lock is activated during normal operation all heater controls other than the OFF
switch will be locked. Deactivating the lock releases the controls. If the lock is activated whilst the
heater is turned OFF, then all heater functions will be locked. If the heater is turned OFF whilst the
Function lock is activated, it cannot be turned ON again until the lock is deactivated.

OTHER OPERATING INFORMATION
■HUMIDIFIER TRAY
Your 1004T is fitted with an enamelled tray
behind the air outlet so that you can humidify
the air. To fill the tray, open the door as
shown in the diagram and pour water into the
tray using the spout built into the door.
The air will be humidified as it passes over the
water in the tray. DO NOT FILL THE TRAY
WHILST THE UNIT IS IN OPERATION.
CLOSE THE DOOR AFTER FILLING. The
1004T is a very high efficiency appliance.
During operation a small amount of water is
produced in the flue tubes. This drains into
the enamel tray. It is quite normal for a small
quantity of water to remain in the bottom of the
tray. If you are using the humidifier, it will
need filling about once a day during the peak
heating season.
■FAN FILTERS
To protect the fan from dust and lint, the
1004T is fitted with 2 fan filters. They are
located at the top, rear of the unit. To clean,
pull the filters out of the unit and remove dust
with a soft brush or a vacuum cleaner. Re-fit
filters after cleaning. Your 1004T has a filter
clean warning indicator that will illuminate
when required, however, weekly cleaning is
recommended during the peak heating
season.
■OUTSIDE FLUE
On cold days steam may be discharged from the flue outlet. This is normal with a high efficiency
appliance and does not indicate any fault.
The heater and its flue must be installed correctly by an authorised person, and the installation must
conform to all local regulations.
The installation also must comply with the instructions supplied by Rinnai.
This heater must be serviced, installed and removed by an authorised person.
No parts or functions should be modified or permanently removed from the heater or its flue.

MAKING ELECTRICAL CONNECTION
WARNING: This appliance must be earthed.
This appliance is suitable for use on 230V 〜50Hz mains only and external wiring must be carried out
to I.E.E. Regulations.
Connect the appliance to the mains electrical supply. A 3amp switched fuse spur with contact
separation of at least 3mm on all poles, must be provided as a means of electrically isolating the
heater for servicing purposes.
Observe polarity and that wiring is correctly restrained.
E EARTH Green / Yellow
L LIVE Brown / Red
N NEUTRAL Blue / Black
IMPORTANT
Do not use a clock or any other type of switch on the electrical supply apart from as the means of
isolating the supply for servicing. (A clock or switch in the supply would also turn OFF the convection
fan and allow overheating to take place).
INSTALLATIONS NOT INCORPORATING A REMOTE TIMING DEVICE
When the heater is to be used as a stand-alone unit the central timer sub PCB fitted on the heater has
to be disconnected from the main PCB. Disconnecting terminal plug H (white, red and blue wires), as
indicated on the top wiring diagram of page 37, will enable the heater to operate independent of a
timing device.
TIME CONTROL
It is necessary to make the time control electrical connection before the unit is fixed to the wall.
The switch live and neutral wires from any remote timing device must be connected onto the terminal
connector situated on the rear of the appliance. Removing the metal protection cover accesses this
terminal connector block which is indicated in the photograph below. (Wiring diagram Page 37)
