Morning, I finished installing my slate hearth pad, got the stove in place, and called two places about double wall stove pipes and didn't get a very clear answer. I have a straight shot out of the top of my stove to a stainless insulated chiminey. I have cathedral ceilings so the stove pipe will be 10 feet long. One dealer said I need an adjustable slip pipe (48-68") and a couple of regular double wall pipe sections. Another dealer said all I needed was a 1' slip section and the rest regular. First guy didn't have the long slip on hand but was getting some next week. Second guy didn't sound like he had everything I needed either. Is this an unusual setup or did I catch these guys off guard? Next Friday I plan on going down to the first guys place and getting what I need. What would be your advice be? Should I special order something to avoid too many sections? Thanks. Dan.
