9. Troubleshooting

Problem
Burner is not running

Possible cause

No power supply
Room thermostat (if being used)
has been set too low
Room thermostat is defective
The automatic oil firing device
indicates malfunctioning (warning
signal lights up). This is displayed
through the signal lamp
"Malfunctioning burner.
The safety temperature limiter has
interrupted the power supply, blow-
out temperature is too high, air
input and air output have been
narrowed down or device could not
cool off afterwards: device was
switched off by pulling out the plug,
instead of by switching off.

Solution
Check with a voltage tester or lamp,
turn on the main switch, change the
fuse, check the supply line for loose
contacts.
If device is being operated without
room thermostat: check whether the
cap of the room thermostat connection
is on, since the heater will not start up
without the cap, if necessary, place the
cap on (the cap contains a power
supply bridge).
Set room thermostat above room
temperature
Examine room thermostat (can only be
carried out by an expert). Change it or
bridge it over at the fastening clamp on
the device in emergency cases and
switch it on manually.
After waiting for about 1 minute, switch
on the illuminated button to suppress
interference. The indication of
disturbance on the control device and
the signal display should extinguish.
The burner will then attempt to start up
again.
You will find a further description of
errors through the LED code directly
on the control device.
When starting up initially, it is possible
that the button for removing
disturbances has to be pressed so
often, until the burner has sucked in oil
that is free of air. Check that the oil in
the reverse flow pipe is free of
bubbles. Heating up will only be
possible after this.
Turn the black protective cap to the left
and remove it. Press the button for
removing disturbances on the STB.
This can be found above the entry
point for the device cable. Get rid of
the cause for overheating (resistance
to suctioning-in or blowing out).
