PRIMING THE FUEL SYSTEM (first use only)

To enable the heater to start easier on the first occasion after the fuel tank is filled, the fuel pump can be activated without starting the heater to feed the fuel into the fuel lines.

) button down. It is important to monitor the fuel delivery along the fuel line to ensure the combustion chamber does not become flooded with fuel.

WARNING

If the combustion chamber becomes flooded, some fuel may come out the exhaust pipe. During first starting the heater it may create excessive amounts of smoke for a few minutes or until the excess fuel is burnt off.

STARTING THE HEATER

To start the heater, press and hold the POWER ( ) button for 2 seconds.

The heater will enter its start-up process where it will perform a system check, start pumping fuel into the combustion chamber, then activate the glow plug to initiate combustion. Once combustion is initiated, the glow plug will turn off and the heater will control as per the set mode and conditions on the control panel.

If it cannot initiate combustion, the heater will retry several times. If it still cannot initiate combustion, the heater will shut down and an error will show on the control panel (refer to troubleshooting section for details).

CAUTION

The heater will go through its pre-set start-up process when turned ON, which will take around

2 minutes and will operate at its maximum output.

After this time, it will operate in the mode and conditions set on the control panel.

DO NOT interrupt the start-up process by cutting power to the heater.

If the heater does have the power cut during start-up it can result in excessive smoke from the exhaust when it is restarted. This should clear after a few minutes of operation.

STOPPING THE HEATER

Once operating, the heater should be shut down by pressing and holding the POWER ( ) button for 2 seconds.

The heater will enter its pre-set shut-down process where the pump will stop, and it will burn off the fuel in the combustion chamber then the fan will continue to run until the heater has cooled down, which can last for around 5 minutes.

6

CAUTION

The heater will go through its pre-set shut-down process when turned OFF, where the fan will continue to operate. After this time, it is safe to disconnect the heater from power and remove any ducts.

DO NOT interrupt the shut-down process by cutting power to the heater before it is completed.

If power is cut to the heater during operation or shut-down, you may see excessive smoke from the exhaust when it is restarted. This should clear after a few minutes of operation.

If it occurs regularly, it can cause carbon build-up in the combustion chamber which may result in poor combustion, inefficient operation and trouble initiating combustion.

OPERATING MODE – HEAT LEVEL

In this mode ( ) the heater is controlled at one of 6 levels – 1 being the lowest fan speed and heat output, 6 being the maximum fan speed and heat output.

The heat level can be adjusted to a higher setting by pressing the UP ( ) button or to a lower setting by pressing the DOWN ( ) button.

OPERATING MODE – TEMPERATURE CONTROL

In this mode ( ) the heater is controlled based on the difference between the set temperature and the measured room temperature. The heater will automatically adjust its heat level based on this difference.

Note: When using the heater in temperature control mode, it is important that the controller is located within the room or area being heated so the room temperature is correctly monitored

The set temperature can be adjusted to a higher temperature by pressing the UP ( ) button or to a lower temperature by pressing the DOWN ( ) button.

When the temperature is lower than the set temperature, the heater will operate at its maximum heat output.

As the room temperature gets closer to the set temperature, the heater will adjust the heat output level down. Once the room temperature reaches or exceeds the set temperature, the heater will turn off.
