Minimum distance between in front of the heater and any object: 20 cm
Minimum distance between on top/below the heater and any object: 10 cm
Minimum distance between each side of the heater and any object; 5 cm
We still recommend that the heaters have more space around them than the minimum distance requirements to ensure that the heat is circulated properly throughout the room.
Nothing should be placed on top of the heaters, as this can pose a safety hazard. If large objects are placed on the heater, the overheat protection will eventually be triggered.
