COMBUSTION CHAMBER (see figure 1)
*
Place burner ring (1) in the burner pot and
replace combustion chamber cover.
* Unlock the sliding bottom drawer (2) by
means of pedal (3) and safety catch (6) and
open.
* The bottom of the combustion chamber and
combustion dish are now accessible, see
figure 2.
Ignition and cleaning can now be dealt with
easily.
IGNITION PROCEDURE
1.
Fill the tank with fuel. Slide the locking
button on the control panel vertically to
open the tank, which hinges forward.
2. Switch to "0"; connect plug to electricity
sypply and switch on at socket.
3. Put capacity regulator in low position.
4. Pour apporx. 1/3 litre of paraffin in the
combustion dish. Crumple some paper into a
ball, light it and drop into the dish to
ignite the oil. Close and lock the sliding
drawer. Check through the top cover that the
sealing around the bottom of the combustion
chamber is visible.
5. Switch to "1". After about 5 minutes the
combustion chamber will be warmed up
sufficiently for the main fan and pump motor
to come into operation. The orange pilot
light will illuminate.
6. After approx. 30 minutes, make any necessary
adjustments to the draught stabiliser.
7. During initial commissioning burn, there
will be some fumes from the heat resistant
paint finish and because the combustion
chamber has been oiled against corrosion.
These fumes will cease after about 30 to 40
minutes.
SAFEGUARDS
*
The burner is equipped with a thermostat
controlling the flame. Should the flame be
extinguished for any reason, this thermostat
will stop the fuel pump as well as the main
fan. For causes, see chapter "Location of
faults".
* An overheating thermostat which shuts off
the fuel supply completely is reset by means
of a push button in the
burner. For causes, see chapter
"Location of faults".
* The fuel supply system is equipped with an
"overflow tube", through which the oil flows
back into the tank incase the pipe to the
burner becomes obstructed. After the flame
has extinguished, the flame control
thermostat will switch off the burner. For
causes, see chapter "Location of faults".
* The burner is equipped with an
"overflow security", located underneath
the bottom of the combustion chamber. This
will come into operation if, over a
period, the fuel is not burnt completely.
The excess fuel will flow from the
combustion dish, via an inlet tube, into a
small container. This container is
positioned on a spring-loaded micro
switch. As soon as this container is half
full, the fuel pump is switched off auto-
matically. For causes, see chapter "Loca-
tion of faults".
* The air combustion fan is equipped with a
thermostat.
