5. OPERATING CONDITIONS
When the heater is switched on the air compressor draws in
air, pressurises it and passes it through an air line to the
burner head nozzle. The air flow causes fuel to be drawn from
the tank. The fuel and air mix is then sprayed into the
combustion chamber. The mixture is automatically ignited by
the spark plug and a high temperature heat stream is
generated in the combustion chamber. Air is drawn into the
unit by a fan and is pushed around the cool chamber situated
between combustion chamber and outer casing. This fast flowing air sucks the heat stream out of the combustion chamber, providing the
required heat. The heat output is governed by the compressor - the higher the air pressure the hotter the flame.
If the system malfunctions a “flame-out” control will operate and automatically cut off the motor and fuel supply. Should this happen,
switch off machine and unplug from mains supply. Refer to trouble shooting chart in Section 8 and/or return unit to supplier for
maintenance.
5.1. FUEL
WARNING! This heater is not suitable for use with Bio-Diesel; use of Bio-Diesel will damage the lter and seals. Damage
caused by use of Bio-Diesel will not be covered by warranty.
The AB series will operate with three types of fuel, paraffin, kerosene or diesel. The following information must be understood before
use.
5.1.1. Paraffin / Kerosene will sometimes cause condensation. If the unit is stored unused (i.e. during the summer) such condensation will
cause the fuel tank to corrode and, when next used, the flame to pulsate due to water in the tank. To overcome the problem, the fuel
must be drained off, if the heater is to be unused for long periods.
5.2. When used in the construction or agricultural industries ensure that
the safety regulations in force are adhered to with regard to distances
from flammable materials and any other specified substances.
WARNING! Air contaminants taken into the heater may affect the
heat output, damage the unit and may cause health problems.
Example: Bodyshop filler dust or paint overspray will damage the
motor bearing, clog the filter and compressor and contaminate the combustion chamber causing flame flutter and health
hazards.
Please note that any parts damaged by filler dust or overspray will not be covered by warranty.
5.3. VENTILATION. Minimum recommended opening for fresh air intake, AB1008 = 0.29m², AB1258 = 0.37m²,
AB1758 = 0.52m².
WARNING! Only use the heater in well ventilated areas. Careful consideration must be given to the placing of the heater to provide
safe and comfortable heating. Ensure continuous ventilation is provided to the heater operating area, allow at least 0.01m2/kW heater
output. A ventilation opening must run to the outside of the premises in which the heater is to be operated.

8. w TROUBLESHOOTINGi
8.1. 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/Paraffin does not start to gel until the ambient temperature
is around -40°C.
