OPERATION

WARNING! This heater is not suitable for use with Bio-Diesel; use of Bio- Diesel will damage the filter and seals. Damage caused by use of Bio-Diesel will not be covered by warranty

PRINCIPLES OF OPERATION
Fuel System: This 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 burner head. Air also passes through the nozzle where it mixes with the fuel and is sprayed into the combustion chamber as a fine mist.
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.
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 the front of the chamber.
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.
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.
Tip-over Sensor: The heater uses a tip-over sensor.
Fuel: the heater operates with paraffin, kerosene or diesel fuel. DO NOT use any other type of fuel.
When used in the construction or agricultural industries ensure that the safety regulations inforce 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/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 overspray will not be covered by warranty. Additionally, a cleaning charge will be made for any heaters damaged by filler dust/ paint over spray.

VENTILATION

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.

STARTING THE HEATER
NOTE: If air has entered the fuel line; possible when new, when left standing for a long period or when the tank level has fallen too low, priming may be necessary (see 5.3.4). It is preferable to start the heater outdoors for the first time, to allow any oils left over from the manufacturing process and transporting to be burnt off in a safe environment. Run it for 10 minutes on this first burn.

Carefully fill the fuel tank with clean approved fuel until fuel gauge ( Fig.1B ) points to ‘F’
Ensure the fuel cap is secure.
Plug the power cord into a suitable power socket. If using an extension lead see Electrical Safety section 1.1.
Turn the power knob in Fig.1 from “O” to the “ “ setting. The green “power indicator” lamp will illuminate, the fan will run followed in 15 seconds by the pump. Inside the next 30 seconds the heater will ignite. If the heater does not ignite the red “Misfire” lamp will illuminate and flash after 3 attempts. Switch the unit off “O” and wait approximately 20 seconds before attempting to ignite again; this 20 seconds will allow the PCB to recalibrate. On successful ignition, if required, increase the heat by turning the knob to setting “ “.
When switching from one heat level to another during operation, it may cease operating and go into the misfire sequence. If this happens, turn the power knob to the “O” position and immediately turn it to the desired heat level.
NOTE: The electrical components of this heater are protected by a fuse mounted in the PCB. If the heater fails to fire, check this fuse first, and replace if necessary. Also check the power source to ensure that the correct voltage is being provided to the heater.
TILTING FEATURE
Loosen the hand screws on the main frame of the heater, position the heater in the desired position and tighten the hand screws to secure the heater in the tilted position.
TO STOP THE HEATER
Turn the power knob to the “O” position, the green “power indicator” will go off. Combustion will stop, and the Cooling Cycle (approx. 5 minutes in duration) will begin. 5.5.2. When the Cooling Cycle is completed (fan stops running), it is safe to unplug the heater.
WARNING! Unplugging the heater before the Cooling Cycle has finished may cause overheating, possible damage to the heater and heat plate, and will invalidate the warranty.
TO RESTART THE HEATER
Wait ten seconds after the cooling cycle has completed.
Turn the power knob to the position and wait 10 seconds before adjusting heat level if required.
Be sure to follow all starting procedure precautions.

MAINTENANCE

Use only original equipment replacement parts. Isolate power before any maintenance. The use of alternate or third party components can cause unsafe operating conditions, and will invalidate the warranty. We suggest following a maintenance schedule as follows.

FUEL/FUEL TANK – Flush every 200 hours of operation or as needed. DO NOT use water to flush the tank. Use fresh kerosene/ paraffin/diesel only.
FILTERS – The Fuel Filter and Oil Filter should be cleaned at least twice per heating season by rinsing them in clean kerosene/ paraffin/diesel. This procedure should also be followed if the fuel is found to be contaminated (Fig.5).
NOZZLE – Nozzles should be cleaned or replaced at least once per heating season. This procedure should also be followed if the fuel is found to be contaminated.
To clean dirt from nozzle, blow compressed air through nozzle front. It may be necessary to soak the nozzle in clean kerosene/paraffin/ diesel to help loosen any particles (Fig.6).
SPARK PLUG – Clean and re-gap every 600 hours of operation, or replace as needed (Fig.7).
After removing the Spark Plug, clean the terminals with a wire brush.
PHOTOCELL – The Photocell should be cleaned at least once per heating season or more depending on conditions.
Isolate power before using a cotton swab dipped in water or alcohol to clean the lens of the Photocell **(Figs.8 and 9).

ONG TERM STORAGE
Unscrew the Drain Bolt and drain fuel into a suitable container (Fig.10).
Using a small amount of kerosene/paraffin/diesel, rinse and swirl the fuel around the fuel tank. Empty the tank completely.
Never store leftover kerosene/paraffin/diesel over the summer. Using old fuel can damage the heater.
Store heater in a dry, well ventilated area.
Be sure that the storage area is free of dust and corrosive vapours. Repack the heater in the original shipping material. Keep this User’s Manual in an easily accessible place.

TROUBLESHOOTING

Although this heater operates with diesel fuel, when the temperatures are 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.
