I'm doing some decorating in my sons flat. There are 2 small Dimplex fan heaters fixed high up on the walls operated with pull cords. As I'm painting the walls I really need to take them down. I just wondered how they are fixed in place. They seem quite firmly attached so I don't think they are just hanging on those keyhole type slots so would I be right in thinking I have to take the cover off and there will be screws fixing them to the wall inside the heater?
TIA John
