SIC39

Message displayed on the remote control: INSUFFICIENT DRAFT - FCS SENSOR

The SIC39 is the shutdown due to clogged air intake or lack of minimum suction.
The main cause is an anomaly in the flow read by the FCS. Clean the air intake and check that the tubes are not bent, dirty, disconnected, and, above all, not reversed. In case of breakage, deactivate the FCS (see page 5) and manually adjust the combustion, so that the stove still operates during the waiting period for the replacement.
