I am going to fit a log burner in a breakfast room which is open plan with the adjacent kitchen. The kitchen has a cooker hood, currently venting to an outside wall. When it is on it's highest setting, you can feel air being pulled in through the air brick vent in the breakfast room, which is going to affect the draw of the log burner. If the cooker hood was changed to recirculation, would this still affect the log burner.
