I have a tex deck and this works with no issues!
I thought the same thing. I looked at putting the top section right into the main body but decided against it because it would radiate the heat directly over the hoppers and make them harder to get into.
It can. The carrying handles also act as a shut offs. Anytime your done you can pull the handles outward and in about 15-20 minutes it will run out of fuel.
Always check with your local codes and laws/regulations first. I have seen this stove working well with low overhangs. I think it doesn't get hot above due to the convection effect of the air flow. Most all of the heat is pulled down from he deflector and circulates. The positive side effect is warm fee and lower legs.
I had the same problem with mine. I missed that there was a handle for a dampener on the very bottom of the stove. I put that on and then opened it. A big difference in the heat output. Check that.
Yes it can be used in a wall tent. Rainier Industries, Bussard, and Davis wall tent manufacturer all recommend our stoves over their prior stoves they sold in the past. They are carrying the Q-Flame and accessories because it works so well versus others.
It is smart to use common sense and keep all combustible the correct distance away (3 feet or more typically). Many folks have this stuffed in the corner of their deck walls that have brick or stone backing. Please check with you local laws/regulations to be sure. It is closed flame so is safe than most heaters in general.
There is no smoke, the wood pellets are 99.9% efficient... smells a little bit like a campfire... it's great
About 10 minutes.
