3. SPECIFICATION
Model No:...............................................IR55
5.1.1. 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.
5.1.2. 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.
5.1.3. 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.
5.1.4. 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.
5.2. Fuel: the heater operates with paraffin, kerosene or diesel fuel. DO NOT use any other type of fuel.
5.3. 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.
5.4. 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.
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.4). 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 care
fully 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.4. If using an
extension lead see section 1.1.11.
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.
6.2. Inclined Feature.
6.2.1. The ow of heat can be directed horizontally or inclined upward with an approximate 10° angle from the horizontal. Loosen the hand screws
(g.5) sufciently but not completely from the side panels of the heater, using the handle bar as a lever locate the shoulder of the hand
screws in the required hole position, and tighten the hand screws to secure. Utilise the lower adjustable deector as required, fully extended
when using horizontally to protect the oor for example.
6.3. To Stop the Heater.
6.3.1. select "o" position on the control panel. combustion will stop, and the 'cooling cycle' (approximately 90 seconds) will begin.
6.3.2. When the 'cooling cycle' is completed the fan stops running and it is safe to unplug the heater.
6.4.1. Be sure to follow all starting procedure precautions.
6.4.2. Wait ten seconds after cooling cycle has completed.
6.4.3. start heater by pressing "I" position on the selector switch, if required and linked to timer or thermostat choose "II" position. select "o" to

6.3.3. rotate the blast tube anticlockwise until the large hole in the slots
aligns with the xings and remove/slide holding the tube
horizontally (g.9), nally resting the assembly as shown in g.10.
Note! some internal parts are delicate and care is required in this
process.
6.3.4 A 16mm A/F socket (g.12) will be required to remove the nozzle. It
will be necessary, with care to spring electrodes apart in removal.
DO NOT remove the top diffuser or damper disc.
6.3.5. to clean dirt from the nozzle, blow compressed air through nozzle
nose. It may be necessary to soak the nozzle in clean kerosene/
parafn/diesel to help loosen any particles (g.12).
6.3.6. replacement of the nozzle and blast tube is the opposite of removal.
6.4.Electrodes
Clean and re-gap every 600 hours of operation (g.12), ensure
electrode gap is between 2-3mm and they do not touch other
components . to clean or replace the electrodes, the blast tube will
require partial removal as described in 6.3.2, 6.3.3 and 6.3.4.
6.4.1. offer a long screwdriver through the damper disc hole and slot to

and swirl the fuel around the fuel tank. Empty the tank completely.
(All as described in 6.1)
The nozzle head sub assembly large disc is a close t inside the blast
tube, hence directing and restricting (throttling) the air ow volume from
the fan through the slotted holes to the diffuser. the diffuser mixes the
supplied air with the fuel to give the optimum burn characteristics. this
optimum setting for each burner is preset in the factory and this position is
recorded and supplied with the heater instructions. the entire sub
assembly can be removed by loosening the cross head screw in the boss
shown in g.12. If removed for cleaning for example, make a note of the
phasing notch (g.13) in the damper ring that aligns with the triangle apex
in the bossed ring. It must be reassembled with the same notch to triangle
apex orientation.
