I am completely new to corn/pellet stoves and I don't know anyone who has one. I read the owners manual several times and then installed my stove. I'm not entirely sure I've done this correctly. I installed my vent with the edge of the thimble about 2 inches away from the edge of my sliding door trim. Manual says 1" from combustibles. Then I read it is not to terminate less than four feet horizontally. Does that mean if I vent it the foot above the door then it falls within the measurements? I took venting and terminating as two separate measurements. One book says it needs to be two feet from and adjacent wall and one says it needs to be three feet. I have it about 2 1/2 feet. As you may be able to tell, the installation area was rather compact as far as obstacles.
