5. OPERATING CONDITIONS
5.1. FUEL AND AIR SYSTEM: This heater is equipped with an oil pump that operates from an electric motor. The pump forces oil from the
fuel tank, drawing fuel to the nozzle in the burner head. Air also passes through the nozzle via a fan and ducting where it mixes with the
fuel, sprayed into the combustion chamber as a fine mist where it is super-heated and forced out the front of the chamber.
5.2. QUICK-FIRE IGNITION: A transformer sends high voltage to a two pronged spark plug. The spark ignites the fuel/air mixture as it is
sprayed into the combustion chamber.
5.3. ELECTRICAL SYSTEM PROTECTION: The heater’s electrical system is protected by a circuit breaker that protects the system
components from damage. If the heater fails, check the fuse first, and replace if necessary.
5.4. FLAME SENSOR: The heater uses a photocell to see the flame in the combustion chamber. Should the flame extinguish, the sensor will
stop electrical current and the heater will shut off.
5.5. FUEL: The heater operates with paraffin, kerosene or diesel fuel. DO NOT use any other type of fuel.
5.6. When used in the construction or agricultural industries ensure that the safety regulations in force are adhered to with regard to distances
from animals, 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/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/paint over
spray will not be covered by warranty. Additionally, a cleaning charge will be made for any heaters damaged by filler dust/paint
over spray.
5.7. VENTILATION
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. A ventilation opening must run to the
outside of the premises in which the heater is to be operated.
The heater requires a fresh air opening of at least 2800cm².
For Example:
- A two car garage door should be open at least 11cm.
- A single car garage door should be open at least 16cm.
- Two 76cm windows should be open at least 20cm.
6. OPERATION
p
6.1. STARTING THE HEATER
NOTE: Always place on a at, stable and level surface and check the electrical supply conforms to the data on the model plate. It is
preferable to start the heater outdoors for the rst time to allow any oils left over from the manufacturing process to be burnt off safely;
run it for 10 minutes on this rst burn. On rst starting or if the heater is started after the oil tank has been emptied; the ow of oil to
the burner may be impaired by air in the circuit. In this case the automatic digital control system will cut out (“safety lockout system”)
the heater and it might be necessary to renew the starting procedure by depressing the reset button on the control panel (g.2). This
button will illuminate; wait two minutes before resetting. Repeat if necessary.
6.1.1. The drain plug is mid position beneath the tank and requires an 8mm hexagon key to operate. Ensure the plug is closed tight before
carefully lling the fuel tank with approved fuel through either ller neck. DO NOT ll or drain whilst the heater is operating.
6.1.2. Ensure both fuel caps are secure after lling.
6.1.3. Plug the power cord into a suitable power socket, indication of power will be shown by the power light illuminating in fig.2. If using an
extension lead see Section 1.1.
6.1.4. Set the selector switch to “I” (ON) and the heater will start. Select “O” to turn off; the heater ame will extinguish with the fan continuing
to run for approximately 90 seconds cooling the combustion chamber. Set the selector switch to “II” (ON) only when used in conjunction
with a timer or a room thermostat. If the heater ceases operating and goes into a misre sequence; set the selector switch to the “O”
position and immediately switch the selector switch to the desired function “I” or “II”.
NOTE: The automatic digital control system of this heater is protected by a fuse in the module. If the heater fails to re, check this fuse
rst, and replace if necessary. Also check the power source fuse and ensure that the correct voltage is being provided to the heater.

6.5.4. For transporting short distances on level surfaces the handlebar and wheels are adequate. For more arduous locations and distances,
lugs are tted for lifting with rope, slings or chains.
WARNING! During handling and transporting, oil may leak. The fuel and breather caps are not an absolute seal, enabling air
to enter and escape during operation. Never transport or service the heater while it is operating, while hot or plugged into the
mains. Severe burns or electric shock could occur.
Use only original equipment replacement parts. The use of alternate or third party components can cause unsafe operating conditions,
and will void the warranty. We suggest following a maintenance schedule as follows.
6.6. FUEL/FUEL TANK
6.6.1. Flush every 200 hours of operation or as needed. DO NOT use water to ush the tank. The drain plug position which is shown in
g.3 and g.5 requires an 8mm hexagon key to remove. It may be necessary to elevate the heater as ground clearance is small. After
draining into a suitable container for recycling replace plug and ush with a minimal amount of fresh kerosene/parafn/diesel only.
Drain again into the container for recycling. Clean drain plug, seal ring, seat and replace, tighten to seal.
6.7. FILTERS
The Fuel Filter and Oil Filter should be cleaned every 50 hours by rinsing them in clean kerosene/parafn/diesel. The fuel lter can be
viewed, accessed and removed through a cutout in the side panel (g.5).This procedure shown in g.6 should also be followed if the
