4. ASSEMBLY
Unpack the heater and check contents (fig.2).
4.1. Slide the axle through the wheel support frame and wheels and retain with the two dome head nuts.
4.2.
Place the heater module on to the wheel support frame ensuring that the air inlet is by the wheels. Place the heater onto the frame,
lining up the holes on the fuel tank flange with the holes on the wheel support frame.
4.3.
Place the front handle on to the fuel tank flange and line up with the wheel support frame fixing holes. Insert bolts through the fuel
tank flange and both frames and secure finger tight only with nuts and washers.
4.4.
Repeat the process with the rear handle.
4.5.
Attach the cord wraps onto the rear handle using the supplied screws and nuts.
4.6. When assembly is complete, securely tighten all fixings.
WARNING! DO NOT use the heater without the support frame fully assembled.
5. OPERATION
•
PARAFFIN, KEROSENE OR DIESEL? - The Sealey AB heaters will operate on all.
•
CLEAN BURNING - A specially designed burner head in a stainless steel combustion chamber ensures a more thorough burn of fuel
which means greater fuel economy and maximum heating effect.
•
FILTER PROTECTION - The compressor unit is protected by extra large filter elements.
•
LARGE FUEL TANK - The AB series heaters will operate for between 8 and 11 hours on a single fill of fuel.
•
SAFETY FEATURES - The AB series heaters are fitted with a flame-out device which cuts the fuel supply when the flame is inadvertently
extinguished.
5.1.
Principles of heat generation (fig.4)
When the heater is switched on the air compressor draws in air, pressurises it and passes it through an air line to the burner head
nozzle. The air flow causes fuel to be drawn from the tank. The fuel and air mix is then sprayed into the combustion chamber. The
mixture is automatically ignited by the spark plug and a high temperature heat stream is generated in the combustion chamber. Air is
drawn into the unit by a fan and is pushed around the cool chamber situated between combustion chamber and outer casing. This fast
flowing air sucks the heat stream out of the combustion chamber, providing the required heat. The heat output is governed by the
compressor - the higher the air pressure the hotter the flame If the system malfunctions a "flame-out" control will operate and
automatically cut off the motor and fuel supply. Should this happen, switch off machine and unplug from mains supply. Refer to trouble
shooting chart in Section 8 and/or return unit to supplier for maintenance.
5.2.
Fuel
The AB series will operate with three types of fuel, paraffin, kerosene or diesel, (not bio-diesel). The following information must be
understood before use.
5.2.1
Paraffin / Kerosene will sometimes cause condensation. If the unit is stored unused (i.e. during the summer) such
condensation will cause the fuel tank to corrode and, when next used, the flame to pulsate due to water in the tank. To overcome the
problem, the fuel must be drained off, if the heater is to be unused for long periods.
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 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 or 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 or overspray will not be covered by warranty.
5.4.
VENTILATION. Minimum recommended opening for fresh air intake, AB2158.V3 = 0.37m².
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, allow at least 0.01m
output. A ventilation opening must run to the outside of the premises in which the heater is to be operated.
5.5.
Running the heater on paraffin / kerosene
The heater has been pre-set at the factory to a setting which is suitable for paraffin, kerosene or diesel and will produce the correct
heat output when first used from new. You should run the heater at the pre-set output in order to ensure the long life, safety and
reliability of the unit.
WARNING! The first time the heater is used, 'fire up' outdoors and run for at least 10 minutes to burn off any oils used in the
manufacturing process.
5.5.1 Ensure that the unit is unplugged from the mains supply.
5.5.2 Fill the fuel tank (fig.7) with paraffin, kerosene or diesel until the fuel gauge points to "F". DO NOT mix the fuels, always drain and
clean out the fuel tank when changing type of fuel.
WARNING! Never refill the fuel tank indoors, always refill outside. DO NOT overfill. Wipe away any spillage before use.
5.5.3 Plug into the main power supply using the 2m extension cable.
5.5.4 Turn the thermostat control knob (fig.6) to the desired temperature setting. The heater has a range from 4
switch to the "ON" position. The lamp and the room temperature display will illuminate and the heater will start.
NOTE: The electrical components of this heater are protected by a fuse mounted on the PCB. If the heater fails to fire, check this fuse (fig.14)
first and replace if necessary. Also check the power source to ensure that the proper voltage is being provided to the heater.
NOTE: The room temperature will display and indicate the following:
If the temperature is less than 0°C, the display will show "LO".
If the Temperature is above 37°C, the display will show "HI"
Actual temperatures will be shown between 4°C and 37°C.
5.5.5 The pump pressure should be +/- 10% of the pressure stated in the specification table above, if the unit is running outside of this
tolerance, adjust the pressure as shown in fig.5.
5.6.
Shut down the heater using the ON/OFF switch and then disconnect from the mains supply (fig.6).
