Thank you for all your advice and help, I am just thinking the same thing. It will be all set up and not work and then I wont know what to do.
Treemoss- Your concern should also be the wood. Even if you have a great draft, the oak you have only being seasoned for 18 months will cause creosote and not burn well. Especially, if it is not in an ideal area for proper seasoning. How long has it been split and stacked? What kind of oak is it? Red oak has more moisture content than most other oak species. Oak in general is a wet wood. I have oak rounds that have been bucked and split in half that are still in the high 40's to 50 imoisture content. Is the oak your main supply? The Mulberry and maple should be ok.
