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.

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.

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.
• no draught damper, or it is incorrectly dimensioned.
• 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.
