Hello all, I've been browsing these forums for a while now, and though you don't know it, you've been very helpful already! I have a Lopi Pioneer Bay FPI that I have tried to find an install crew for, but it doesn't seem to want to happen. I would like to see if it's possible to install it myself. I have a masonry fireplace, with a damper installed. There's a chimney rain cover on the top. 1) Is it suitable to run a flexi-pipe all the way down it? Or should I buy straight parts for it? 2) Are there any permits (county/state) I need to be aware of? 3) I've uploaded some photos. The chimney rain cover has some pins(?) securing it, what's the easiest way of removing them? 4) With the flex-pipe is it easier to run it down the chimney or pull it up? Thanks for reading! I am nervous and excited to get it up and running!
