I have sent messages to Camp Chef with no return. I read another person on here had the same problem I did. The flame will go too low to cook if you try to use all three burners. The flam will go into the tube by the knob; this is not safe at all. I will be returning mine to costco too. Too bad I bough the extra grill case, and the click ignition. Another thing too, is that the click ignition is terrible. They try to make a one size fits all, that does not look professional, nor does it work well.
