Troubleshooting
Resetting the alarm
Switch off the power to the burner for approximately 10 seconds.
In the event of a fault that requires intervention in the burner, the power
must always be switched off before work begins. After action has been
taken, the alarm is reset automatically when the power to the burner is
switched on.
ALARM
High temperature in downpipe
Failed start
High ambient temperature
Fan not working
Excess pressure, combustion chamber
Starter element not working
21
Risk of entrapment!
Do not insert hands or objects in the feed auger.
Before any work is done on the feed auger, the power cable
must be disconnected from the burner.

The voltage is measured in the sensor's connection points on the circuit
board when the burner is live. During resistance measurement, the sensor
must
not
be connected.
Switch off the power to the burner and detach the plug before
cleaning or service or before the burner is detached from the
boiler.
Troubleshooting
In the event of a problem, first check all the conditions required for the
burner to work:
• Does the burner have power? Is the operation indicator lit up?
• Are all control units, thermostats, etc. set correctly?
• Are all safety devices, overheating protection, hatch switches, etc. in
normal operating mode?
• Is the burner receiving pellets?
Look at the grate after a failed start. If there are unburned or slightly
singed pellets there, the most probable cause is that the draught is too
high.
If all the pellets have burned up, the most probable cause is that there is a
problem with the pellet supply.
If the cause of the problem is none of the above, all the burner's functions
must be checked. If the burner is in alarm mode, i.e. the alarm indicator is
lit up, it must be reset.
Follow the operation of the burner. Measuring instruments can be very helpful
when troubleshooting.
External fault sources
Common circumstances that give rise to operating problems:
• the inclination of the feed auger from the horizontal plane is not
40°±5°.
• the pellets do not meet the requirements under the standard.
• draught >15 Pa.
• lack of draught damper.
• large area in flue.
• irregular fuel supply because the feed auger has not travelled far
enough, the pellet store is of poor quality or there are a lot of crushed
pellets in the store.
• grate in incorrect position.
Checking the feed auger's capacity
A. Detach the quick coupler at the downpipe and hold your hand over the
quick coupler part that is attached to the hose.
B. Connect the feed auger to a wall outlet and let it rotate through 3.5-4
revolutions.
C. The quick coupler part on the hose must be filled with pellets. If this is
not the case, check the inclination of the feed auger and its insertion
into the pellet store.
