LIVING FLAME HAS GONE, NO MORE YELLOW FLICKERING FLAMES, ALONG WITH HIGH HEAT SETTING.MY GAS MAN BLEW OUT THE BURNER, AND BLEW DUST/SUT ALL OVER, INCLUDING HIS FACE, WITCH I DIDNT TELL HIM ABOUT, BUT THAT BLOW COST ME £40. AND I HAD TO CLEAN UP BEFORE THE WIFE GOT HOLME. IT DID MAKE A SMALL IMPRUVMENT BUT NOTHING LIK IT SHOULD BE.
