Chimney sweep
The unit must be set as follows for measurement
by the chimney sweep:
1) Set the switch on the control panel to winter.
2) Set the temperature on the temperature controller
higher than room temperature to trigger a heating
cycle.
3) Also set the internal thermostat for the 2-stage
burner operation higher than the actual room
temperature, to trigger maximum output.
Once the unit has ignited it is possible to take
the measurement approx. every 2 minutes
at a measuring point in the flue gas pipe.
Once the measuring process is complete, bring
the internal thermostat and room temperature
controller back to the previous condition.
We reserve the right to modify the dimensions and design as part of the ongoing technical development process.
In order to replace the STB thermostat, refer
to the following table and the corresponding labelling
on the mounting bracket in the unit.
