Hi all, Thanks for everyone's advice on here regarding installing the liner. Still have some adjustments to make thanks to bholler. I want to make sure I have everything to properly install the insulated liner to the stove. Below are some pics of the coupler I received in the kit from rockford chimney supply and the stove. So how does all this fit together? The coupler "necked" down slips into the stove until it hits the bolts inside that hold the removable flue collar. The other end will not fit over the insulated section. It probably would fit if I peel the outer wall and insulation off. I do have a section of liner that I can experiment on. Advice on the proper way to install this? Do I need extra parts? Thanks!
