6. OPERATING CONDITIONS
6.1. KEROSENE AND DIESEL FUEL USAGE
These AB heaters are factory adjusted to give the most efficient burn on kerosene but will also burn diesel. Note that kerosene will tend to
burn more cleanly than diesel. Care should be taken to provide at least the minimum amount of ventilation recommended when burning
diesel.
6.2. STORAGE OF FUEL
Always store kerosene and diesel in a well ventilated area well away from general living space. Do not store in direct sunlight
or near a source of heat or other source of ignition such as a torch or a portable generator. Do not use fuel that has been stored from
one season to the next as it may have deteriorated and will not burn properly in the heater. Store the fuel in a suitable container which
complies with requirements set out in local authority regulations.
WARNING! Air contaminants taken into the heater may affect the heat output, damage the unit and may cause health problems.
Example: Bodyshop filler dust / paint overspray will damage the motor bearing, clog the filter and pump and contaminate the combustion
chamber causing flame flutter and health hazards. Please note that any parts damaged by filler dust / paint overspray will not be covered
by warranty. Additionally, a cleaning charge will be made for any heaters damaged by filler dust.
7. OPERATION (REF. FIG.1A)
7.1. START UP
7.1.1. Fill tank with clean fuel. Only use Diesel or Kerosene. The fuel
gauge on top of the tank allows to check fuel level.
7.1.2. Connect the power cord plug to a AC220-240V 50 Hz earthed

8.1. Regularly wipe the enclosure using a soft sponge or cloth. For very dirty parts, use a sponge wetted with lukewarm water and a mild
detergent, then dry using a clean cloth.
8.2. Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow compressed air through air inlet.
8.3. Regularly inspect the power cable: if worn, cracked or damaged have it replaced by technical service.
8.4. Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a plastic bag, put it in its packing box and store it in
a dry, ventilated place.
8.5. LONG TERM STORAGE
If the heater is to be stored for a long period of time, drain the fuel through the fuel cap opening. Rinse and swirl a small amount of fuel
within the tank and then empty it fully. When you come to use the heater again do not use old fuel which has been stored from the
previous season. Use of old fuel can damage your heater.
Although our heaters operate with diesel fuel, when the temperature is below 0°C diesel additives are required to maintain the diesel’s
viscosity. Typically diesel can cloud in freezing conditions and will start to gel. You will need additives for your fuel in these conditions.
Kerosene does not start to gel until the ambient temperature is around -40°C.
