Wrong
Action in case of chimney fire!
If a chimney is not cleaned often enough, or if the wrong type of fuel is used (e.g. damp
wood) or the air flow is maladjusted the chimney may catch fire. In this case close the air
supply to the fire chamber and call the fire brigade.
Never try to extinguish it yourself using water!
