WARNING! Air contaminants taken into the heater may affect the heat output, damage the unit and may cause health problems.
p
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 openings for fresh air intake.)
Model: AB602.V2 = 0.15m
WARNING! Only use the heater in well ventilated areas. Careful consideration must be given to the placing of the heater to provide safe and
p
comfortable heating. Ensure continuous ventilation is provided to the heater operating area. Allow at least 0.01m
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.

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.5.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 as the heat
builds to maximum (approximately two minutes) the dome at the output end of the heater will begin to glow. Observe the colour of
the dome to check that the heater is producing the correct heat output, as indicated below. Stand at least 3 metres away from
heater to make observations.
a) NORMAL
CHERRY RED IN THE MIDDLE PROGRESSING TO AN ORANGE ON THE
OUTSIDE RIM OF THE DOME (see fig.4).
b) TOO HOT
ORANGE ALL OVER. WARNING! This output will damage the combustion
chamber and invalidate warranty.
c) TOO COOL
ANY DULL GLOW PROGRESSING UPWARD TO CHERRY RED ALL OVER.
(Heater odour emissions will also indicate incorrect settings.)
5.1.4. To adjust the heat output, locate the air pressure valve (fig.5.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 screwdriver and loosen the
locking nut. Turn the screw clockwise to increase the air pressure and thus increase the heat output.
Turn the screw anticlockwise to decrease the air pressure and thus decrease the heat output. Make
small adjustments only and give the heater time to stabilise before observing the effect on the colour
of the dome. When the colour is normal as described above in section 5.1.3.(a) tighten the locking nut.
5.1.5. Turn off the heater at the rocker switch and unplug from the mains supply. ( except for the
AB200, see section 5.2.6 below ) 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. Plug back into the mains supply and start the heater, run for two minutes before making any adjustment to the air pressure valve.
Locate the valve (fig.5.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 screwdriver and loosen the locking nut. Turn screw half a turn anticlockwise to decrease the air pressure, and thus decrease
the heat output, to compensate for the hotter burning diesel fuel. Retighten the locking nut.
5.2.4. As the heat builds to maximum (approximately two minutes) the dome at the output end of the heater will begin to glow. Observe the
colour of the dome to check that the heater is producing the correct heat output as indicated above in section 5.1.3. Stand at least 3
metres away from heater output to make observations. Minor adjustments to heat output may be required during the first 60
hours of use. If necessary readjust the air pressure valve as indicated in section 5.1.4. to achieve the correct dome colour.
5.2.5. Turn off the heater at the rocker switch and unplug from the mains supply ( except for the AB200, see section 5.2.6 below ).
DO NOT touch the heater outlet as this will remain hot for some time. Store in a dry, safe, childproof area.
5.2.6. Always shut down the AB200 using the ON/OFF switch. Leave the heater plugged into the mains supply for at least 3
minutes. ( The AB200 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.
5.3.
Monitoring the heat output. The heat output should be checked on a daily basis by observing the outlet dome operating colour, as
described in Section 5.1.3. 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.
5.3.1. If there is any doubt about the efficient operation of the heater, the air pressure should be
checked more exactly using a pressure gauge which will measure up to 30 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.5.B. Start
the heater and compare the pressure reading with the chart shown on the right. If the
reading differs from the chart this indicates that maintenance is required as laid out in
Section 6. You should also investigate whether the environmental conditions at the location
of the heater are suitable, with particular reference to the amount and quality of the air supply.
5.3.2. Turn off the heater as instructed in sections 5.1.5. & 5.2.5. Remove the gauge and replace the plug before turning on the heater again.
