LAST EDITED ON Oct-30-04 AT 07:37AM (MST)[p]In my opinion I wouldn't worry so much about build up in the pipe you would have to use it for along time for that to become a problem, but make sure you have a dampner in the pipe to control the air flow and put it as close to the stove jack that you can this will hold more heat in the pipe. take a good bed roll with some kind of under covering, if the weather turns cold you will be glad you got it! that stove will not hold wood all night long and it gets damn cold at 2 in the mornin, one other little tip we use is to get a coleman lantern,about 1/2 hr before you get up just light it and let it burn it will knock the chill off in the tent quickly and dry the air.One last thing make sure you got some kind of screen on your pipe to keep the hot poppers off your tent if you pull too much draft, Good Luck Pilgrim!...Greg
