I used to use chips and used to soak them. No more. I use chunks and do not soak them. If smoke is rolling out every seam, hole, gap around the door, etc. you have TOO MUCH smoke! Granted, starting up you probably will have that for a short bit. It should lessen and thin considerably. The thin blue is close to invisible, sometimes IS invisible, but you can still smell it. That is what you want.
