1.1. eleCtriCal safety
WarninG! It is the user’s responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and
all electrical connections for wear and damage. Sealey recommend that an RCd (Residual Current device) is used with all electrical
products. You may obtain an RCd by contacting your local Sealey stockist.
If used in the course of business duties, it must be maintained in a safe condition and routinely PAT (Portable Appliance Test) tested.
electrical safety information, it is important that the following information is read and understood.
9 ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
9 Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
9 Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is tted with the correct fuse - see
fuse rating in these instructions.
8 do not pull or carry the appliance by the power cable.

9 Only use parafn, diesel or kerosene to fuel this heater, in accordance with instructions contained in this manual.
9 locate heater on a level and stable surface.
WarninG! only use heater in well ventilated areas. ensure continuous ventilation is provided to the heater operating area via
windows and doors etc. If people are not required to be present in the heated area, the volume of air to be heated (m³)/heat output
(kW) ratio must be at least 10:1 and people must be advised not to remain in the heated area for prolonged periods. If people
are required to be present in the heated area, the volume of air to be heated (m³)/heat output (kW) ratio must be at least 30:1.
Ventilation must be to the outside of the premises in which the heater is to be operated. The total open area (m²) must be at least
0.003 times the total heat output (kW). The volume concentration of
WarninG! do not use the heater near ammable material, liquids, solids, gases or compressed gas cylinders etc.
8 do not stand or place any object less than 3m from the heater output and keep the heater a minimum of 2m from any walls or
objects.

5. operation
5.1. fuellinG the heater:
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 parafn. Parafn has been rened to virtually eliminate contaminants, such as sulphur, 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 lter.
8 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 re or explosion.
8 do not store parafn in the living space. Parafn should be stored in a well ventilated area outside the living area.
8 do not store parafn in direct sunlight or near a source of heat.
8 do not use parafn that has been stored from one season to the next. Parafn deteriorates over time, old parafn will not burn
properly in this heater.
5.2. Ventilation:
5.2.1. risk of indoor air pollution and carbon monoxide poisoning. use
heater only in well ventilated areas.
5.2.2. Always provide a fresh air opening in the heated space of at least
2,800 cm2 (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)
5.3.1. Fill the tank with paran or other approved fuel until needle on fuel
gauge points to “F”. Replace fuel cap and tighten rmly.
5.3.2. Connect the heater to a power source. You must use 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 heater will ignite g.3.
note: On rst 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 fuel gauge reading 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 rst and replace 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, 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.

adjustment or repairs.
6.1. lonG terM storaGe:
6.1.1. Unscrew the fuel cap.
6.1.2. Using an approved siphon, remove the Parafn or diesel.
6.1.3. Using a small amount of Parafn or diesel, rinse and swirl the fuel inside the fuel tank
6.1.4. empty the tank completely.
note: never mix water with fuel, it will cause rust inside the tank.

parafn only.
6.3. spark plug:
Clean and re-gap every 600 hours of operation or replace as needed. After removing the spark
plug, clean the terminals with a wire brush, re-gap the terminals to 0.140” (3.5mm) g.4.
6.4. fan blades:
6.4.1. The fan blades should be cleaned at least once per heating season, depending on conditions.

6.5.2. To clean dirt from nozzle, blow compressed air through nozzle front. it may be
necessary to soak nozzle in clean parafn or diesel to help loosen any
particles g.6.
photocell:
6.5.3. The photocell should be cleaned at least once per heating season or more
depending on conditions, use a cotton swab and water or, alcohol to clean the
lens of the photocell. Be certain to reinstall the photocell in proper position as
shown below g.7.
6.6. filters:
6.6.1. The fuel lter and oil lter should be cleaned at least twice per heating season
by rinsing it in clean parafn or diesel. Contaminated or old fuel could make
cleaning necessary immediately g.8.

Athough 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/Parafn does not start to gel until the ambient temperature is
around (-40°C).
