Hi i was wondering if you could help. I have just moved into a new house with a blocked up fireplace in the lounge which currently has two 2inch by2 inch holes cut into it for ventilation. The wall is flat and so i'd like to put an electric fire suite up against it, however this will cover the two ventilation holes. Can i cut a ventilation grill higher up in the actual chimney (1.5 metres or so from the ground)? If i just push the fireplace up to the skirting board and so leave 1/2 inch gap or so between the holes and the new suite will that leave enough ventilation. Any advice would be very gratefully received.
