Hey all we bought this quad 5100 to heat our last home and it served us well there for around 5 years. New home to us in March with a brick fireplace meant the insert was moving with us. Good bit of cutting and blocking with sheet metal to make room for the stove and close everything off. About 22' of Insulated flex liner from Rockford chimney supply. Not a pro install by any means but we're all so glad it's back to keep us toasty as the weather gets crisp. I've been lurking here since researching the install at our last home years ago. Lots of good knowledge to be had here and wouldn't have tackled it without hearth.com. Thanks to all for sharing!
