Check the condition of the outer burner pipe as well.
Switch off the power to the burner before the work begins.
Resetting the thermal relay
When the thermal relay on the
downpipe has been triggered,
the 'ALARM' indicator lights up
constantly.
When it is reset, the burner must
be dead.
Remove the thermal relay's
enclosure on the downpipe.
Reset it by pressing the button
on the thermal relay.
Refit the enclosure and restart
the burner.
Switch off the power to the burner before the thermal relay's
enclosure is removed.
Safety system
The p ellet system's safety system consists of:
• overheating protection against excessive boiler temperature.
• thermal relay in downpipe.
• 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.
