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 requires
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/Combustion 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 will 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-activates 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 operation
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.
