Why does smoke come down a chimney in an adjacent room?
This is caused by the working appliance drawing oxygen from wherever it can so as smoke leaves one flue it is drawn down an adjacent chimney pot down the flue through the fire opening and drawn towards the working fire. There are three remedies: • Block off the flue of the unused fire in the adjacent room; • Perhaps fit a taller pot; or • Try more ventilation to the outside from the room with the working fire.
