Do a burn in it with it outside of your tent. Get it good and hot for a half hour/hour or so, then put it in your shack. You should be fine after that...
I wouldnt worry too much about getting the walls hot. Leave some free space around it and you will be fine. I have a permanent shack and trust me if your stove is hot enough to make the walls hot you wouldnt be able to breath in there.
I never got my shack out this year, too busy with work. The season is ending and I already can't wait for next year.
Ok guys, everyones getting tired of all the wise cracking, thread derailing attempts at mindless humor in this forum. Be serious and help a person out or don't post.
