Gas fire

I remember my grandmother getting a new gas fire put in by the council (about thirty years ago) to replace the old coal fire and back  boiler she had. The council chaps also put a new flue liner in the chimney. Apparently checked it and left. Next day one of her neighbours called round and had been knocking on the door for a few minutes. Looked through the window and saw my gran collapsed on the floor. Called the police and they broke in and called the ambulance service.

Turns out the flue had pushed a brick out of the chimney on it's way down and this had flattened the liner. Gran was suffering from CO2 poisoning. After a week in the hospital she was released home. Council had put another flue liner in and thoroughly checked the installation before allowing her back. They reckon if the neighbour had called round a few hours later my gran would have been a gonner.
