Has worked for years and then this year it has become a problem. You lite the polit light turn up the flame and before you can sit down it goes out and you relight and go to sit down and it goes out again!!!! It does stay lit but this is only you have gone thru the process an angravting amount of time. Of course this is when it gets cold and it the most in the summer when it is not in use it is fine,go figure?
