When used in the construction or agricultural industries ensure that the safety regulations in force are adhered to with regard to
4.3.
distances from
flammable materials and any other specified substances. refer to General safety in section 1 for recommended clearances.
WARNING! Air contaminants taken into the heater may affect the heat output, damage the unit and may cause health problems.
Example: Bodyshop filler dust will damage the motor bearing, clog the filter and compressor and contaminate the combustion chamber
causing flame flutter and health hazards. If contaminants are present the heater must be supplied with ducted clean air, see 4.4.
Please note that any parts damaged by filler dust will not be covered by warranty. Additionally, a cleaning charge will be made
for any heaters damaged by filler dust.
4.4.
VENTILATION.
Minimum recommended opening for fresh air intake, AB502.V2 = 0.17m2
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 0.01m2/kW heater output.
this should be divided equally between floor and high level. A ventilation opening must run to the outside of the premises in which the
heater is to be operated. If the operating area has no direct access to clean fresh air we recommend you run a large gauge duct from
the outside of the building to the inlet of the heater in order to provide a clean air intake. Ensure that the duct is laid so as to not
compromise safety.
4.5.
Flue connection
For indoor use this heater must be connected to a flue pipe to vent exhaust gases outside. the heater can only be operated
without a flue when it is outside. to obtain a good draught, the flue gases must rise as much as possible vertically. Ensure that there is a
minimum 2 metre vertical flue length without any bends. Avoid horizontal sections and ensure that any bends are smooth.
5. OPERATING INSTRUCTIONS
5.1.
Running the heater on paraffin
the heater has been factory pre-set for paraffin 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. Minor adjustments to heat output may be required during the first
60 hours of use. these adjustments are made to the air pressure valve (see fig.4.A). once the unit
has completed the running-in period it should not be necessary to alter the air pressure again until
a new air filter is fitted or a change of fuel takes place.
5.1.1. Ensure that the unit is unplugged from the mains supply.
5.1.2. fill the fuel tank with paraffin. Do not over-fill. Wipe away any spillage before use.
5.1.3. Plug into the main power supply and switch on the heater. the heater will ignite and will build to its
maximum heat in approximately two minutes.
5.1.4. Always shut down the heater using the ON/OFF switch. Leave the heater plugged into the
mains supply for at least 3 minutes. ( the heater is fitted with an aftercooling timer that allows
the fan to rotate for approximately 2 minutes after shutdown, to cool the combustion chamber and
release residual heat.) nEVEr sHut DoWn tHE HEAtEr BY PuLLInG out tHE PLuG.
DO NOT touch the heater outlet as this will remain hot for some time. store in a dry, safe, childproof
area.
5.2.
Running the heater on diesel
the heater has been pre-set in the factory for the use of paraffin. Because diesel burns hotter than
paraffin it will be necessary to decrease the air pressure to give out the correct heat output. Failure
to make this adjustment will damage the combustion chamber and invalidate your warranty.
5.2.1. Ensure that the unit is unplugged from the mains supply.
5.2.2. fill the fuel tank with diesel. Do not over-fill and wipe away any spillage before use.
5.2.3. to ensure correct combustion set the air pressure using an accurate pressure gauge.
5.2.4. use a pressure gauge which will measure up to 10 p.s.i. and has a 1/8" BsP thread.
With the heater turned off and unplugged from the mains, remove the threaded plug
from below the air pressure valve and attach the gauge, see fig.4.B. start the heater and
compare the pressure reading with the pressure chart shown on the right.
5.2.5. to adjust, locate the air pressure valve (fig.4.A), which is in the centre portion of the air
inlet grill at the back of the unit. Hold the adjusting screw steady with a screw driver and loosen the locking nut. turn the screw
anticlockwise to decrease the pressure until it compares with the diesel figures in the pressure chart.
5.2.6. to adjust the heater back to paraffin follow the process in section 5.2.5, but turn air pressure valve screw clockwise until the
pressure compares with the paraffin figures in the pressure chart.
5.2.7. Shut down the heater using the ON/OFF switch. Leave the heater plugged into the mains supply for at least 3 minutes.
nEVEr sHut DoWn tHE HEAtEr BY PuLLInG out tHE PLuG.
remove the gauge and replace the plug before turning on the heater again.
5.2.8. DO NOT touch the heater outlet as this will remain hot for some time. store in a dry, safe, childproof area.
IMPORTANT! this heater can be connected to a remote room thermostat ABt04 (not supplied) via the socket situated in the side
panel. If no thermostat is connected then the grey socket cover supplied MUST be inserted into the socket or else the heater will
not operate. note that the heaters have a pre-purge time and an after cooling time. this means that a) the burner will ignite
approximately ten seconds after motor start and b) the fan will run for approximately two minutes after shut down. this is normal and
correct operation.
5.3.
Monitoring the heat output
5.3.1. If, after a period of time, the heat output begins to fall this indicates that either the unit requires maintenance, as laid out in section 6,
or that the environmental conditions the unit is operating in are not correct, see section 4.
DO NOT ATTEMPT TO TURN UP THE AIR PRESSURE TO COMPENSATE FOR HEAT LOSS as this could result in damage to the
combustion chamber and would invalidate the warranty.
