We bought two Big E's this year and the first one is up and running fine. The second one is being set up now. However, the burnpot collar (I think that is what you would call it) is missing. Can you still use the stove without this part? My dealer said he would have to order one and it could take a couple of weeks to get. I would like to start using the stove now. The dealer said oh yes, you can use it that way. The collar just tries to keep the pellets from bouncing off to the side. Does this sound right? Thanks for any advice!!
