You can replace the HC at https://7thfloorvapes.com/index.php...vers/da-buddha-ground-glass-heater-cover.html or... you can lift the HC a bit on it's base. EDIT: Some units do not have clips... or the clips (pieces of wire screwed to floor of unit that keep the HC tight) If not you can work with shims Slide it up on the cylinder it is on, being certain that you have more than 1/2 of cylinder still covered. If not secure, you use shims... small slivers of cylindrical pieces that you fit between the HC and the base. 7th Floor LLC has these. If you want a couple, Message me privately and I will take care of it.
