6. Instructions for Use
6.1. Start-up
Fill tank with clean fuel. Only use Diesel or Kerosene.
The fuel gauge on top of the tank allows to check fuel level
Connect the power cord plug to a 230 V 50 Hz earthed electrical supply system.
Earthing is mandatory.
Having completed the "start-up" above, the left display window shows the ambient temperature value.
Push the power switch to "on" position, now the display shows the last setting temperature.
If the ambient temperature is lower than default temperature, waiting for few seconds, the heater will
start.
If the ambient temperature is higher than default temperature, push thermostat control button to set
desired temperature, waiting for few seconds, the heater will start.
COLD START-UP: at low temperature keep the air vent hole (see Fig. 6) closed by a finger during
ignition to make start-up easier.
VENTILATION MODE: Simultaneously pressing the setting buttons of the room temperature, the flame
goes out and the device continues to function as a fan.
ABNORMAL OPERATION: in case of malfunction (flame failure, reduced air flow, bad combustion,
etc.) the heater stops and the LOCK-OUT code will be showed on the display window.
6.2. Manual reset/restart
If the heater is in lock-out mode, check and remove the cause of lock-out before restarting the heater.
To reset, turn the ON/OFF switch to 0 and then (after few sec.) again to I. In case of repeated
malfunction, call technical service. Turning the thermostat control knob will NOT reset the heater.
6.3. Shut-down
Move switch to "OFF" (O) position. DH1-50 will run a post-ventilation phase for cooling down
combustion chamber. Unplug the unit when not used for a long time.
Never disconnect the heater from mains to stop it while in operation. Always allow the
cooling sequence to be completed (DH1-50), otherwise the residual heat could damage
internal components.
Do not cover the heater. Do not block the air inlet and outlet.
The heater outlet is very hot during operation and after use. Do not touch! Use personal
protecting equipment if needed.
Children should be supervised to ensure that they do not play with the appliance.
The appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge.
Unplug the heater before moving it. Never pull the cable to unplug or move the unit.
Do not leave the heater unattended when in use.
