run, the external auger may need up to 20 minutes to load. After the pellets are loaded the burner will
go into IGNITION mode then PRE-BURN mode then finally BURNING mode where it will remain until it
reaches the temperature by the thermostat. When it reaches this temperature the burner will go into
END BURN mode and finally END BLOW until all the pellets coals have extinguished. At that point the
burner will be in WAITING mode until the boiler calls for more heat which starts the whole process over
again.
To stop the burning
, turn the boiler’s thermostat down or turn the burner OFF from the BURNER’s
menu or keep OK button down for 5 seconds.
Caution!
Never turn off a working burner from the main power switch of the boiler. Do not leave the
burner unattended when it has been necessary to turn off the burner’s power while in operation.
