QUESTIONS AND ANSWERS
Can I place the controller in a different room from the fireplace/heat source?
No. The controller must be mounted in the same room as your heat source. Make sure that the controller is
in a position where it can easily detect changes in the room temperature from your heat source, e.g. 2-4
metres away from the heat source. Do not place the controller in the hallway or near the doorway, around
a corner from the heat source, or far away (>6 metres) from the heat source in a large room.
How far away from the heat source should I place the fan?
You should keep at least 1.5 metres of distance between the heat source extraction point and the fan.
However, the recommended distance between the extraction point and the fan is 3 metres.
