Safety system
The pellet system’s safety system consists of:
• overheating protection against excessive boiler temperature.
• thermal relay.
• non-combustible hose (melts) between feed auger and
downpipe.
• fan with fan guard.
• photoresistor for flame monitoring.
• blockage if the ambient temperature is too high.
The majority of the functions cannot be influenced by the user
and require no special control.
Check regularly that the hose between the feed auger and
the downpipe is intact.
Changing the inner burner pipe
Detach the burner from the outer burner pipe.
Unscrew this screw. Turn the inner burner pipe anticlockwise
and pull the pipe out.
Move the lip suspended in the pipe to the new burner pipe.
Refit in reverse order.
Check the condition of the outer burner pipe as well.
Check that the burner has been disconnected
from the power supply before working on it!
Any intervention in the boiler’s electrical
equipment that requires tools must be carried out
under the supervision of a qualified electrician.
Disconnect the plug before service or if the
burner is removed from the boiler.
