ASSEMBLY

4.1. Unpack the heater and check the contents. Should there be any
damaged or missing parts contact your Sealey stockist immediately
4.2? Attach the handle by lining up the holes in the handle with the holes in the upper shell of the heater (fig.1).
4.3. Insert screws and tighten.
4.4. Remove heater and packaging material from the carton.

Although our heaters operate 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).

OPERATION

5.1. FUELLING THE HEATER see fig.2A above right
5.1.1. This appliance is designed to operate safely at a minimum ambient temperature of -20°C.
5.1.2. For optimal performance of this heater, use paraffin. Paraffin has been refined to virtually eliminate contaminants, such as sulfur,
which can cause a rotten egg odor during the operation of the heater. Using diesel fuel can cause excess soot production. DO NOT use bio-diesel as this fuel will damage your heater’s seals and filter.
DO NOT use fuel such as, benzene, alcohol, white glass, camp stove fuel, paint thinners, or other oil compounds in this heater. these are volatile fuels that can cause a fire or explosion.
DO NOT store paraffin in the living space. Paraffin should be stored in a well-ventilated area outside the living area.
DO NOT store paraffin in direct sunlight or near a source of heat.
DO NOT use paraffin that has been stored from one season to the next. Paraffin deteriorates over time, old paraffin will not burn properly in this heater.

5.2. VENTILATION
5.2.1. Risk of indoor air pollution and carbon monoxide poisoning. Use the heater only in well-ventilated areas.
5.2.2. Always provide a fresh air opening in the heated space of at least 2,800 cm (3 sq. ft) for each 29 kW / hr. of heater output.
5.2.3. Provide a larger opening if more heaters are being used.
5.2.4. Minimum Ventilation Opening Needed for this heater is 64cm
5.3. STARTING THE HEATER (IGNITION)
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. It is referable 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.
5.3.1. Fill the tank with paraffin or other approved fuel until the needle on the fuel gauge points to “F”. Replace the fuel cap and tighten firmly.
5.3.2. Connect the heater to a power source. You must use an extension cable that is at least 1.8 meters long and is a minimum of 14 AWG rating.
5.3.3. Push the power switch to the “ON” position. The power indicator lamp will light and the heater will ignite fig.3.
NOTE: On the first ignition or after refueling you may hear a grinding sound just before ignition. This is the fuel pump removing the air from the fuel line. Your heater will start up within seconds. If it does not start repeat start-up procedures with a fuel gauge reading of at least 1/2 tank.
NOTE: The electrical components of these heaters are protected by a fuse mounted in the PC board. If the heater fails to ignite check this fuse first and replace it if necessary. Also, check the power source to be sure the proper voltage is being provided to the heater.
5.4. STOPPING THE HEATER
5.4.1. Turn the power switch to the “OFF” position. Combustion will stop and the Cooling Cycle will begin. approx. 7 mins.
5.4.2. When the Cooling Cycle is complete the fan will stop running and it will be safe to unplug the heater.
NOTE: Unplugging the heater before the Cooling Cycle has been completed may cause overheating, and possible damage to the heater and heat plate.
5.5. RESTARTING THE HEATER
5.5.1. Wait ten seconds after Cooling Cycle has been completed.
5.5.2. Follow all start-up procedures above.
