Hey people,

I just got my YLL 3 yesterday and figured this would be the correct way to put together the inserts with the spacer. Strangely, when I use it like this, there is a small flag of smoke that does not come from the device but as if i were burning something when heating?

I stopped immediately of course, but cannot seem to figure it out, while I do not find any manual explaining how to do this. Would be grateful for any help.
