No, it works, there just are a couple of things to consider.
There are a number of recent threads in this forum, so have a look at those titles and try those suggestions.
Placement of the wood
May sure the wood is dry / seasoned.
Also keep in mind, you won't always "see" a lot of smoke. There is dirty smoke (bad) and clean smoke (good) and the idea is that you want a clean smoke
If the wood itself isn't burning, read through those threads, try the suggestions.
If that doesn't fix it, Call CS on Monday and discuss.
