• The safety thermostat - located on the fuel supply pipe of the burner, will shut down the burner if
its temperature is higher than 95 °C (55 °C for boilers DxxPX, PXxx). Thus, it protects the burner
from return ignition of pellets in the conveyor and at the same time from operation with clogged
flue gas exhaust from the boiler (e.g. in case of a failure to remove dust from the boiler, flue gas
duct and chimney). The safety thermostat will also put the burner out of operation in case the hose
between the burner and conveyor gets perforated to prevent flue gas from escaping to the boiler
room.
INFO - After any shutdown of the burner when an error message (ALARM) appears on
the display it is necessary to immediately find the cause and remove it. After removing the
cause of the error you can start the burner by merely turning off and on the burner switch,
which is located on the boiler panel.
