7.6 Burner control reset button
An error can cause the burner control to lock out.
When this happens, the red LED on the control panel
will illuminate. After eliminating the cause of the error,
you can reset the appliance using the reset button.
Note
Before resetting, always eliminate the cause of the
error.
The appliance's error conditions (8.3 "Error
conditions") and how to resolve them are described in
the error condition summary (11 "Troubleshooting") .
7.7 Flue gas thermostat reset button
A malfunction in the flue gas discharge, e.g. a
blockage in the chimney, can lead to the flue gas
thermostat locking out. This state is evident when the
push button on the flue gas thermostat has been
activated (refer to the figure). Once the cause has
been removed, and the sensor has cooled down
sufficiently, press this push button to reset (if the
sensor is not sufficiently cooled down, the flue gas
thermostat will immediately lock out again). The
appliance will then automatically start up again, if
there is a demand. If this is not the case, please
consult the error condition
summary
(11 "Troubleshooting") .
Note
The draught diverter may be hot.
