5. OPERATING CONDITIONS
5.1. PARAFFIN, KEROSENE AND DIESEL FUEL USAGE
These AB heaters are factory adjusted to give the most efficient burn on paraffin and kerosene but will also burn diesel. Note that
paraffin and 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.
WARNING! Never use any other fuel such as petrol, benzene, alcohol, camping stove fuel, paint thinners or other oil
compounds. USE OF THESE VOLATILE FUELS MAY CAUSE A FIRE OR EXPLOSION.
5.2. STORAGE OF FUEL
Always store paraffin, 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.
5.3. FILLING THE FUEL TANK
Never fill the fuel tank indoors. Always fill the fuel tank outdoors on a level surface. Take note of the position of the fuel gauge whilst
filling the tank and do not overfill it. Never refill the tank whilst the heater is operating or is still hot.
5.4. VENTILATION REQUIREMENTS
  Usethisheateronlyinawellventilatedarea.Youshouldprovideanopeningtotheoutsideairofatleasta3squarefeet(0.9M²)for
every 100,000 BTU/hr of heat output. Provide a larger opening if more than one heater is being used.
5.5. SIGHTING THE HEATER
Always install the heater so that it will not be directly exposed to water spray, rain, dripping water or wind. The heater should not be
placed near to any combustible materials. The minimum clearance from combustibles is 1.2m from the top of the heater, 1.2m from
the sides of the heater and 2.4m from the front of the heater. Never use the heater in spaces which contain products such as petrol,
solvents, paint thinners, dust particles, volatile or airborne combustibles, or any unknown chemicals.

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.
6. THEORY OF OPERATION
6.1. FUEL SYSTEM.Theheaterisequippedwithanairpumpthatoperatesofftheelectricmotor.Thepumpforcesairthroughtheairline
connected to the fuel tank, drawing fuel to the nozzle in the burning head. Air also passes through the nozzle where it mixes with the
fuel and is sprayed into the combustion chamber in a fine mist.
6.2. QUICK FIRE IGNITION. A transformer sends high voltage to a two pronged spark plug. The resultant spark ignites the fuel air mixture
as it is sprayed into the combustion chamber.
6.3. AIR SYSTEM. A fan is turned by the heavy duty motor which forces air around and into the combustion chamber, where it is super
heated and forced out of the front of the chamber.
6.4. TEMPERATURE LIMIT CONTROL.Theheaterisequippedwithatemperaturelimitcontroldesignedtoturntheheateroffshouldthe
 internaltemperaturerisetoanunsafelevel.Ifthisdeviceactivatesandturnsyourheateroff,itmayrequireservicing.Oncethe 
temperature falls below the reset temperature, you will be able to restart the heater.
6.5. ELECTRICAL SYSTEM PROTECTION. The heater’s electrical system is protected by a circuit breaker that protects the systems
components from damage. If the heater ceases to work, check the fuse first and replace if necessary. See maintenance section 8.9.
6.6. FLAME SENSOR. The heater uses a photocell to ‘see’ the flame in the combustion chamber. Should the flame extinguish, the sensor
will cut off the electrical current and the heater will shut down.
7. OPERATION
7.1. TO START THE HEATER.
7.1.1. Fill the tank with fuel until the fuel gauge points to “F”. Do not overfill.
7.1.2. Ensure that the fuel cap is replaced and fully tightened down.
7.1.3. Unwind the mains cable from cable tidies and plug the heater into the mains power
supply.
7.1.4. Push the power switch to the ON position and the heater will start. The heater will run
up to temperature and then maintain an output of 13.2kW (45,000 Btu/hr) with an
airflow of 170cfm.
NOTE: The electrical components of these heaters are protected by a fuse mounted on
the PC board. If the heater will not fire, check this fuse first and replace if necessary.
Also check that the proper voltage is being supplied to the heater.
7.2. TO STOP THE HEATER.
7.2.1. Turn the power switch to OFF and disconnect the mains power supply. NEVER SHUT DOWN THE HEATER BY PULLING OUT THE
PLUG. DO NOT touch the heater outlet as this will remain hot for some time. Store in a dry, safe, childproof area.
7.3. TO RESTART THE HEATER.
7.3.1. Wait ten seconds after shutting off the heater.
7.3.2. Turn the power switch to ON.
8. MAINTENANCE
8.1. MAINTENANCE SCHEDULE
WARNING! Never attempt to service the heater whilst it is still hot, wait until it has cooled enough to touch. Unplug the heater
from the mains supply before servicing.
