INTRODUCTION & SPECIFICATIONS
NOTE: Your heater is set to be used with paraffin, to adjust for diesel use refer to Section 4.
The Sealey AB heaters are made to DIN30697 standard and built to survive the rigor of bodyshops, workshops and large work areas (these heaters
are not for domestic use). A sensor will automatically cut off the motor and fuel supply if the flame is inadvertently extinguished. The heater
can be fuelled with paraffin or (with minor adjustments to air pressure systems) diesel. Diesel, however, will not burn as cleanly as paraffin.
DO NOT use any other type of fuel. A specially designed burner head in a stainless steel combustion chamber ensures a thorough burn of fuel
which results in economical use and maximum heating effect. The cast alloy compressor unit is protected by a large filter element and the fuel
line is fitted with an in-line filter to ensure trouble free operation. The AB heaters will operate for between 6 and 18 hours on a single tank of fuel.

3. ASSEMBLY
Unpack the heater and check contents. Should there be any damaged or missing parts contact your
supplier immediately. If your model is supplied with wheels refer to fig.1 for assembly as follows:
3.1.
Slide axle (4) through wheel support frame (3).
3.2.
Install wheels (5) then cap nuts (9) on axle ends and tap lightly into place.
3.3.
Place heater on wheel support frame and line up holes on the fuel tank flange with holes on the wheel
support frame.
3.4.
Place handle on fuel tank flange and line up with the wheel support frame fixing holes. Insert bolts (6)
through the fuel tank flange and both frames and secure finger tight only with nuts (7) and washers (8).
3.5.
When assembly is complete, securely tighten all nuts.
4. OPERATING CONDITIONS
4.1.
Principles of heat generation
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. Heat will
cause the steel dome in the heater outlet to glow. The intensity
of this glow is an indication of the output. 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 7 and/or return unit to supplier for maintenance.
4.2.
Fuel
The AB series will operate with two types of fuel, paraffin or diesel. Before operating the heater you must determine which type of
fuel you will use in order to effect the correct heater settings. The following information must be understood before use.
4.2.1. Paraffin
The heat output is governed by the compressor - the higher the air pressure the hotter the flame. The AB series heaters have had the
air pressure pre-set at the factory to accommodate paraffin (because it will burn more cleanly than diesel). When the heater is new
however (or when the unit has been returned from service) the settings may require minor adjustment to accommodate reductions in
air flow through a new air filter. Incorrect settings will cause flame problems and may emit fuel odours resulting in damage to the unit
and an uncomfortable working environment. Paraffin 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, paraffin must be drained off and replaced if the heater is to be unused for a long periods.
4.2.2. Diesel
AB series heaters are pre-set at the factory to accommodate paraffin. If diesel is used without changing the setting the air pressure
will be greater than is required resulting in an excessively hot flame which will damage the unit. Before using diesel the system must
be adjusted by decreasing the air pressure to the point at which the diesel will burn to generate the correct heat output.
p WARNING! Failure to adjust to the correct air pressure will damage the combustion chamber and invalidate your warranty.
The spark plug will require cleaning every 50 hours of use in order to remove carbon deposits (see Maintenance Section 6). We recommend
cleaning the plug at least once every standard working week if less than 50 hours.
When used in the construction or agricultural industries ensure that the safety regulations in force are adhered to with regard to distances from
