Hello All,

My Father-Inlaw gave me a mid to late 1990's pellet burner..I would like to hook this up and give it a try this year and have a few questions about the venting of it..

I now have a wood burner (old late 1970's or early 1980's model) and the triple wall steel chimney needs replaced..I thought I would instead of replacing it just upgrade to the pellet stove..I currently have 8" stove pipe that goes straight up from the top of the stove...The pellet burner vent comes out from the back so I will need one elbow and then straight up..

The biggest question I have is what do I need to do about the large hole in my ceiling and in my roof as the pellet stove only needs a 3" vent..Going from the 8" I currently have to a 3" is going to leave me with a big hole..I don't know what is avalible for piping this out but I would assume I would have to change the box that fastens to the ceiling and the boot part on the roof for the smaller pipe..Is this correct? Or is there a easier way??

Thanks for any and all advice..
