Hello all. I am going to be installing my little wood stove in a few weeks and was just wondering how to install the conector pipe in this particular situation. I have always hooked into existing fireplaces or pipe thimbles so I never came across this. I am going directly for the stove collar to a ceiling support box. The distance from the top of the flue collar the the support box doesn't have any "give" so how do you slide the pipe up onto the adapter on the support box and then pull it down into the stove collar as it would fall apart, or at least expose the crimps? Is that where the "slip joint pipe" comes in? Is that the only/best way?
