I am installing a enviro windsor freestanding in the lower level of my home. The outside wall is completely exposed so I have the options of sending the vent pipe straight out the wall or inside up and out. (I bought the stove complete, and vent pipe for up and out came with it.) Is there any reason why I should go straight out the wall and up? Is there a high risk of chimney fires with pellet stoves? How hot does the vent pipe normally get? My clearance to combustibles requirement for the vent pipe is 1". I am looking to place the vertical pipe about 6" from the wall.
