Pellet stoves can be direct vented as well. I used one 3 foot section of pipe straight out the back with an end cap that directs the fumes out and down at about 45 degrees. as long as you dont have any combustables within 30 inches (I think thats the minimum) mine is about 36 inches from the outlet to the ground, you should be fine. find a local pellet stove dealer in your area (I would avoid the TSCs, Home Depots, etc) and ask as many questions as you can. I researched and visited several dealers in columbus before making my final descision. www.hearth.com has a forum section dedicated to pellet burners, but as with any online forum, there are tons of people that like to help and a few asshats as well. your mileage may vary.
