.Press the ONIOFF button
The ON indicator will illuminate green.
The convection 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 into ignition mode.

TurningOFF
.Press the ONlOFF button
ON I OFF
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 1s to lower
the temperature within the unit. Do not pull
out the power cord during this time.
CAUTION !
Do not pull out the power cord or disconnect the power during combustron to cause
extinction, or straight after extinction, as this may cause damage to the unit.
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.

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
22C.
Set the desired room temperature with the
up and down buttons while looking at the
display section.
The"Set Temp" can be set to "C' or between
"16" - "26 , or "H" (continuous combustion
on High).
The "Room Temp" will display "L" (when
lower than IT), "1"
- "30 (at intervals of
1"C),or "H (when higher than 30%).
Once a temperature is set, it will be stored in
the microcomputer'smemory.
Note :
Rooms may not arrive at the set temperature
due to the construction of the room, the
location of the unit, or external temperatures.

If the heater does not ignite then the pre-set temperature may not be set to a setting which is
higher than the actual room temperature.

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.
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 morefrequently 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 room temperature may be shown as
being lower than the set room temperature, however,this is normal.

. HUMIDIFIER TRAY
Your 1004FDT 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 1004FDT 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 inthe 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
1004FDT 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 1004FDT has a filter clean
warning indicator that will illuminate when
required, however, weekly cleaning is
recommended during the peak heating season.

Testing Unit
Purge air and swarf from the gas line.
Connect gas. Refer to AGA pipe sizing chart if
in doubt about the size of the gas line.
Connectioncan easily be reached from the top
and rear of the unit. Check for escapes, using
soapy water after turning the gas on.
Turn "OFF' the gas supply.
Removethe front cover.
Remove the test point screw from the pressure
test point on the front of the main solenoid valve
and connecta pressure gauge.
Turn "ONthe gas supply.
Plug the unit in and turn "ON" the electrical
power (CAUTION:240 Volts insidethe unit).
Press the "ONIOFF switch to operate the unit.
Turn the thermostat to "HI". The unit should
ignitewithin 10seconds. If it does not ignitethe
first time it will spark again after 10seconds.
If the unit still does not ignite, there may beair in
the gas line. Turn control "OFF and then "ON"
again. Turn the thermostat to "HI".
Turn on ALL other gas appliances at their
maximum gas rate, in accordance with
manufacturerinstructions.
With all gas appliances runningat the maximum
gas rate, the pressure gauge at the test point of
the Infinity should read at least 1.13 kPa on
Natural Gas or higher depending on your area.
On LPG the pressure should be no less than
2.75 kPa. If it is not, the gas supply is
inadequate and the heater will not operate to
specification. Check the gas meter, regulator
and pipe work for correct operation
I sizing as
required until the required gas pressure is
achieved.
NOTE: The regulator on the 1004 FDT is
electronically controlled and factory preset.
Under normal circumstances it does not
requireadjustment during installation.
Perform the "Gas Setting" procedure on page
27 only if the unit is not operating correctly and
all other possiblecauses for incorrect operation
havebeeneliminated.
Pressthe "ONIOFF switchto stop operation.
Disconnectthe electrical power supply.
Turn "OFFthe gas supply.
Remove the manometer and replace the test
