I have used a Cannon Caress gas fire for several years without any problem. It's now taken to going out, quite suddenly, after anywhere from fifteen minutes to an hour or more on any setting. It can be blazing away cheerfully on the highest setting, for example, then give a slight 'clunk' or click and its off ! I turn the gas off , just to be on the safe side but its then some time before it is willing to restart.
Any advice gratefully received.
Harry.
